Replace the battery on your iPhone 4S.

  • Author: Walter Galan
  • Time required: Example: 15 to 30 minutes
  • Difficulty: Moderate

Replacing the battery on the iPhone 4S requires minimal disassembly.

Edit Step 1 Rear Panel  ¶

Edit Step 1 Rear Panel  ¶ 

  • Before disassembling your iPhone, be sure it is powered off.

  • Remove the two 3.6 mm Pentalobe screws next to the dock connector.

  • During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws.

  • The 5-Point Screwdriver should only be used once, as it has the potential to strip the screws.

Edit Step 2  ¶

Edit Step 2  ¶ 

  • Push the rear panel toward the top edge of the iPhone.

  • The panel will move about 2 mm.

Edit Step 3  ¶

Edit Step 3  ¶ 

  • Pull the rear panel away from the back of the iPhone, being careful not to damage the plastic clips attached to the rear panel.

  • Remove the rear panel from the iPhone.

Edit Step 4 Battery  ¶

Edit Step 4 Battery  ¶ 

  • Remove the following screws securing the battery connector to the logic board:

    • One 1.7 mm Phillips screw

    • One 1.5 mm Phillips screw.

  • Use a plastic opening tool to gently detach the battery connector from the socket on the device. Start lifting off the connector from the bottom side, by placing the tip of the tool between the loudspeaker enclosure and the metal cover of the connector.

  • The battery connector comes off vertically from the logic board. Do not apply force sideways.

  • Pay attention to the pressure contact underneath the top screw of the battery connector. This may come loose while prying the battery connector from its socket.

Edit Step 5  ¶

Edit Step 5  ¶ 

  • Use a plastic opening tool to pull the pressure contact from underneath the battery connector.

  • When reinstalling the pressure contact, be sure to clean it with a degreaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to create wireless interference.

  • Take notice of the position of the small black ground clip on the upper screw of the battery connector. This clip is attached only by the upper screw. When reinstalling, it must be aligned so the gold contact point will press against the back cover.

  • Be careful not to rip off the battery connector socket soldered on the logic board. There are 4 very small soldering points awaiting this mistake!

Edit Step 6  ¶ 

Image #1

Edit Step 6  ¶ 

  • Insert the edge of a plastic opening tool between the battery and the outer case near the bottom of the iPhone.

  • Run the plastic opening tool along the right edge of the battery and pry up at several points to completely separate it from the adhesive securing it to the outer case.

Edit Step 7  ¶ 

Image #1

Edit Step 7  ¶ 

  • Use the exposed clear plastic pull tab to peel the battery off the adhesive securing it to the iPhone.

  • Remove the battery.

To reassemble your device, follow these instructions in reverse order.

If your iPhone reboots constantly after the replacement, you need to do a "Hard Reset" by holding down the Home- and Sleep-Button for about 10 seconds (until the device restarts).

If you have WiFi and/or Cellular connection problems with the new battery, try restoring the device using iTunes.

When I removed the battery the glue was holding it in. I used the screw driver to pry it out. It sparked and I'm sure shorted the logic board. VERY IMPORTANT ONLY USE PLASTIC TOOL WHEN REMOVING BATTERY! Now I have no service. I swapped a different logic board into same phone and works fine. Any suggestions on how to fix the old logic board are appreciated.

Well, the phillips screwdriver was a bit awkward. Had to hold screwdriver top down with one hand and turn driver with other hand. All else was as stated. Never had to touch any internal parts with my bare hands just used tools. That saves the worries about static or corrosion. One part that I failed to see in write up is the small case ground. Don't loose it it will come loose once screw is out.

brriverrat, · Reply

A couple of suggestions.

1). If you are over about 40, some sort of hands free magnifier helps a lot - I used a headband mounted jewelers magifier called an Optivisor.

2). A pair of fine tipped tweezers and a gentle touch will let you grab the pressure contact in step 5 without getting skin oil on it.

3). Work over some sort of tray to stop small parts from rolling away.

4). If you don't have a spudger or a set of plastic case opening tools (or you know you have them, but can't recall their exact location at this moment...*cough*), the corner of an an expired credit card, or a stiff guitar pick will work to pry the battery loose. It will likely bend the card though, so do use an expired one. I used an empty Starbucks gift card I found in a junk drawer...

Did you check to make sure the antennae did not get disconnected? It is easy to disconnect, so you have to make sure to check that it snaps into place. The connector is the gold piece connected by a black wire.


Try to upgrade to latest IOS..it will solve the problem


Replacing the battery made my battery life ten times worse. Did I install it wrong?

kcwatanabe22, · Reply

did you ever get your battery issue resolved?


Install worked as described, and with a bit of luck.

There needs to be a more detailed photo/explanation in Step-5 regarding the positioning of the small multi-layered piece (with black coating) that is held down by one of the screws (above antenna connector and below battery connector) and that must be 'in-position' (without a screw) while you place the new battery and attache the batt. connector.

Thanks for the guide.

I have replaced my battery which is now powered fine but I now don't have a phone signal which is "searching" can anyone advise?

I have managed to successfully replace the battery but now I have no phone signal which just says "searching". Can anyone advise what I need to do ?

Vic Smith, · Reply

If the phone is not connecting to you provider (also date/time is reset), plug it in to your computer/ itunes for a while. It should go back to normal.

Ian Booth,

People should be advised that the screwdrivers provided with the iFixit battery replacement fix kit are slightly magnetized, which was a surprise. So touching anything except the screws themselves with them is a bad idea.

threephi, · Reply

Another general comment about this guide: the photos are very nice, but it would be extremely foolish to open your phone and remove the battery while holding it in your hands, as is depicted. Work on a flat, clean, open table top to minimize the chance of losing any screws or other parts.

threephi, · Reply

i didn't know what possibly went wrong, i enclose the assembly and there's no gsm signal, so i re-open the back cover and install it again, then the signal comes right back.

I was a bit confused, as my Battery APN was 616-0582, which was not listed on the "Replacements Battery Parts" which is sold here. Only Apple Part #: 616-0580, 616-0579, 616-0581 are listed there. But The 79 I bought works like a charm as a replacement of my 82. At least after restarting after I got a "searching" in the first two minutes.

Starkiller, · Reply

After I replaced the battery according to these instructions, I, too, had the scary "searching" error when looking for my service provider, even though my 4G was available. I plugged the phone into my computer and rebooted the phone. When it came back on, my provider showed right up. All is well. Do watch for that little black and gold thingy...it's teeny, and comes loose no matter what you do. Just pin it between the phone and connector on the top screw, with that little gold dot facing you. Put the screw in to hold it in place.

This was so easy! Slow and careful. The longest bit was getting the battery off of the adhesive.

It's medium in difficulty but it is my first repair! :)

Replacement went well, but I did encounter the "Searching" problem on re-start. Phone could not find carrier. Fix was simple though. Just reset network settings located under Settings/General/Reset (scroll to bottom)/Reset Network Settings.

Zero Knight, · Reply

Just changed my battery.

I concur with others regarding the "No Service" issue after restarting. Before tearing it down again to check the antenna connection, I rebooted the Phone and then the second time I had service. So if you are fairly confident of your handiwork then definitely try this first!

As others have stated it is worth keeping a very close eye on the black earthing clip and it's positioning before removal. It is held down with the top screw and must be repositioned before the screw is fitted. I used the thinnest end of the Plastic Opening Tool to slide into the fold of the earthing clip in order to guide it into place. My Pentalobe tool was slightly magnetized so I used that to bring the screws in for tightening with the Philips screwdriver.

Thanks ifixit!

This worked wonderfully for me!

My iPhone 4s battery was discharging very rapidly since I installed iOS 7. Although I'd read reports that it's a software problem with the latest iOS, the phone is over two years old.

This repair has greatly improved my phone's battery life. Before I replaced the battery, when the phone reached ~7%, it would shut off at any time, and I could only use it for about two hours. The battery can now deplete all the way to 1% and I have much more battery life. I'm very happy with the battery kit from iFixit; it's revitalized my phone.

The battery replacement isn't easy -- the screws are very small indeed. The "pressure contact" popped out when I disconnected the battery. I had to look at the high resolution iFixit image to understand its replacement. To replace, first attach the battery connection, and then slide the "pressure contact" beneath the top screw of the battery connection. Fine-nosed tweezers make this much easier than fingers.

easy and quickly replaced the battery. thanks for your helpful guide.

The installation worked well for me. I did use latex gloves to avoid the transfer of oil from my skin to the device parts. The screws, particularly on the inside of the device, are tiny so it is really important to have good lighting. A free-standing shop magnifying glass would make the process of inserting the screws easier.

brhanks, · Reply

I just completed the replacement. The first time the device would not power on without a power cord connected. There was no service and I was unable to activate Wi-Fi. So I opened the phone up again, removed the battery connector, aligned the ground clip and cleaned it with alcohol. This time the phone was able to boot without the power cord attached, but the screen was flickering like !@#$ around the corners. Wi-Fi worked and so did service. After a minute I noticed that the flickering was less noticeable and now after 30 minutes it's completely gone. So if you have the flickering issue, just wait a few minutes.

tomteichert, · Reply

After replacing the battery the phone wouldn't connect to GSM. At first I thought it had to do with the pressure contact that connects to the back cover so I redid it a few times but no luck. Finally had to take it to a service center, luckily the solution was only a few minutes away. Connect the phone to a wifi network, pull the SIM card and then insert it again after a while, enter your pin and you"re up and running again. I was not the first customer who had entered the shop with this problem. Best wishes from Sweden!

Extremely good guide - took all of 10 minutes to change the battery without any issues. As always just ensure you have all the right tools and worth reading through other members comments. Well done iFixIt!

Adrian Casemore, · Reply

An easier repair than I anticipated. My advice is once you get the back off, take a minute to study the orientation of the battery connector and the small black ground clip underneath the top screw; it will inevitably pop out of position when removing the battery thus requiring realignment. Go slow and use minimal force when prying both the battery connector and battery. After powering on the phone, I too had the problem of acquiring a cell signal. After five minutes of the phone displaying "Searching," I did a reset (holding sleep/wake button and home button simultaneously) and when phone powered back on I immediately received a signal from my carrier. Looking forward to greater battery life between charges.

sbatzel, · Reply

- I had the same issue with "searching" network and I was *unable* to address it by: (i) resetting the network settings, (ii) removing the SIM card, (III) connecting my iPhone to iTunes, and (iv) setting the time automatically.

- Eventually, I had to manually set the date (especially the year) and time to the right settings, then reboot.

- After that everything got back to normal.

just completed this very easy battery replacement on my daughters iPhone 4s. Steps are really easy to follow, one thing I found helpful was to use a tweezers to put the pressure contact back underneath the top screw of the battery connector!

collinsmikep, · Reply

This is soooooo easy.

I also had the 'Searching' issue.

Powered down, and back up again and all was fine.

Shame on Apple for making this appear to be elusive.

I did use a magnifying light, and a pair of needle nose type tweezers for the pressure contact. I also cleaned the back and the connectors with alcohol like they recommended, but not sure if it made any difference.

Well done ifixit!

Followed instructions and had a perfect installation. Two tips: before unscrewing the battery clips, pry up the battery to loosen it from the adhesive, carefully. Then unscrew the clip and carefully pry it up. That way, there's no frantic popping of the grounding clip. Then pull off the battery. Also, once put back together, power up, then remove the SIM card and reinstall (like everyone else is doing). Presto, new battery and fully functioning iPhone 4s.

Both of the battery are made in China.The battery which assemble in the 4s is produced by amperex technology limited, the ifixit replace battery is produced by SONY electronic(wu xi)limited.

Procedure was easy with two caveats:

1) I needed a small pair of needle-nosed pliers to remove and reinsert the pressure contact.

2) It took quite a bit of pressure to release the battery from its adhesive.

Everything went super simple. Before I shut down my phone I put it in airplane mode, after turning the phone back on I took it off airplane mode and everything was working perfect. I did not experience the network problem, this may be the trick.

Installation seemed fairly simple for it being my first time. I had some issues with the LCD Glitching a bit but after a few hours it went away. I'm currently monitoring the battery life right now with the app called Battery Doctor. I will post a reply in a few days. I would recommend reading through the comments before installation!

It was harder than I thought it would be... the screws are so super tiny! I had to curse quite a lot to get them back in :)

My advice: DON'T DRINK COFFEE BEFORE replacing your battery! :)

I also had the "searching" problem, and at first my phone wouldn't connect to itunes (error message), but after resetting network settings and restarting my phone, all went back to normal. Curious how long my battery will last!

Thanks a lot from cold Germany - worked like a charm, took about 20 min with one interruption (soccer game on tv). Was my first try on an iPhone, and yes, the screws are tiny, and yes, you definitely need some extra light and a magnifying glass if you are over 22 :-D. I also had the issue with "searching network". After resetting the network settings it did work instantly! Keep on with the great work here at ifixit !

Just got my kit, followed the instructions and had 0 problems except could use larger photos of the inside of the phone as we are going along. Oh and the pressure contact - I never did touch it with anything other than the plastic tool of the screw driver. Not quite clear what position that was in from the pictures, could use a close up there too. Otherwise iFixed IT!

It took approximately 15 minutes. I watched a video on youtube where a guy was replacing the battery with the one bought from ifixit. All occured without any problems, very well. I appreciated the way the battery was packed and the fast shipping. Thank you ifixit !

After following instructions and replacing battery I still have not been able to get the new battery to charge. Anyone have issues with this? Otherwise phone seems to be working great.

spacerlede, · Reply

Battery replacement straightforward and no dramas. I had done the pre-reading (i.e. this guide and all the comments) and was ready for the black/gold bit to sproing across the room, which it didn't. Steps very easy as above. I removed the black/gold thing from the phone while I was taking the old battery out so I didn't lose it.

All went back together smoothly - I used a couple of toothpicks to align the black/gold thing + the connector from the battery before screwing them in - the ribbon on the connector was stiff and I was reluctant to be too heavy handed trying to force it in. So gently pushed it into place, screwed back in, back cover on and away we went.

Phone came back to life with 75% battery life and found my network with no dramas. All in all done before the children could come and have a look at what I was doing (10-15 min tops).

Many thanks - now to repair the broken iPad glass.

My 4s got submerged in water and I replaced the battery. Afterwards, when I attempted to turn it on. The apple showed up on the screen but no more. I took the battery out and charged it in another phone and then put the charged battery into the phone again. Once again when I tried to turn it on, the apple appeared and no more.

This phone has so many pictures of my children and important messages on it that I would like to retrieve. Any suggestions on what I should do to get this phone working again?

rooster, · Reply

Just did the replacement in about 15 minutes. A few notes:

1) Having a magnifier that you don't have to hold in your hand is key. I have a set of pivoting jewelers lenses that clip on to my reading glasses.

2) The Phillips screwdriver that comes with the "Liberation" kit is crap. Blunt, crude, wrong tip angle. Unusable. Get a set of real, or even semi-real fine screwdrivers.

3) establish a wide, open, clean area for working. If one of those little screws skitters out of your grip you don't want to be searching under table debris for it.

4) Pointy tweezers. With the size of the screws in this thing they won't seem so pointy.

5) The instructions above are vague about how the battery connector gets pulled off or pushed on. I still can't quite figure out the combination of sideways and up that worked. I ended up using the plastic tool to lever the connector to the right, while lifting...no, that wasn't it.

hiltondier, · Reply

I have to be honest, I went to the trouble of changing my battery using an ifixit kit but the new battery had no better life than the one I was replacing. I've been through so many guides trying to figure out if there is some setting I've got it on that drains battery life but I can't find anything. Meanwhile, I didn't have a warranty to invalidate, so to speak, but my only chance to rescue my phone now is to take a gamble that my insurance providers will be able to fix it. Now I'm worried that I'll have invalidated that policy. I LOVE the idea of ifixit's battery replacement kit as much as I'd love to stick it to Crapple but I'm afraid for me, this kit wasn't worth the money or the hassle. But on a side note, I'd like to urge anyone read this to avoid Crapple products. They're designed to fail so that you just buy more of their products but I will absolutely not be giving them any more of my money. Thanks anyway ifixit.

Ok, so wash your hands. Get everything on a flat surface before you dig in. Great directions except I would add that prior to removing the battery connector cover, take note of the little black ground clip (with the gold contact point) which gets attached under the top screw. I had a hard time getting this back in place as I didn't notice exactly where it was prior to removing the battery connector cover. These directions are great otherwise. Thanks for saving me some moola by letting me replace the battery myself!

soczkas, · Reply

Be very careful as to where you decide to do the repair. I dropped one of the internal screws doing mine and my roommates and I spent a good half hour scouring the kitchen/dining room floor for the 1.5mm screw. Using a towel under your phone while doing the repair was an easy way to keep screws from bouncing away when I inevitably dropped them again.

With the help of a youtube video (https://www.youtube.com/watch?v=nYYdbk3U...) I got the battery replaced fine - but also had the "No Service" / Searching problem others have commented on ...

To round off the battery replacement instructions, it would be good to indicate to users that:

1) the Time & Date are set back to 1 January 1970 when the battery of the iPhone is replaced

2) to fix this, it's easiest to sync in iTunes ...

3) if the "No Service" / Searching problem persists, power down & up a few times

That worked for me ...

Thanks ifixit for the great product & service!

Hello, I was not able to remove one of the two screw once phones open, impossible. It became smooth. Can you help me? I think of having damaged the battery by forcing to remove the screw, and my iPhone does not light up any more.

juliette, · Reply

I did this with a couple of hitches. The battery glue sticks like sh1t to a blanket so I broke both my plastic tools trying to pry it out. I used the screwdriver to pry the battery after that and I got a spark, but fortunately I didn't fry anything.

The takeaway:

Go gently with the plastic tools


shumbies, · Reply

The "No Service" error may come up after the replacement. As others have mentioned, restarting the phone again is the best first step. Then reset the network settings if that fails. I tried to edit this into the guide but it got rejected. I've seen other guides missing software next steps as well and then have to dig through the comments or search elsewhere for a solution. Not sure why iFixit doesn't want software steps in the guides as it is an important step to a solution.

Just changed the battery 15 minutes ago and everything still works (so far). Since I'm so extremely near-sighted, I found it a lot easier to take off my glasses and go through all the steps dealing the screws and the ground clip having my nose about 5 centimeters from the phone. So glad I finally did this. I was going from 100% to 45% just getting up, leaving my house and riding the train to work (less than 2 hours). Hope I can keep it working. I stopped at the Apple store today and priced out the 6 and 6 Plus and %#*@, the exchange rate makes them so fricking expensive - nearly ¥100,000 for the 128G 6 Plus. That's the equivilent of about $1,000 under a standard 2-year contract like in the States.

I did find that the phone took way to long to find the network again and when it did it was 2 bars short of full power which wasnt the case beforemso I went into the phones settings into network then reset the phones network settings and restarted the phone like a normal computer.

It was much faster this time.

I had the advantage of already owning the iFixit Pro Toolkit before I started so I was able to remove the spring contact under the top screw with the curved tweezers (and re-position it before putting the screw back in). I also used the tweezers to gently hold the contact still while I tightened the top screw. I also had the 'Searching' issue on bootup but I figured it was a network contact initialization issue since the network data would be wiped so I set the phone to Airplane Mode for about 15 seconds and then switched it back. It connected instantly. Hope this helps.

Once iFixit sent me the right screwdriver (don;t get the cheap open, get the pro grade) I was able to do the swap in less than ten minutes. It's easy, and I'm an idiot, so do it yourself and don;t pay someone to do it for you.

Nice guide. I had a trouble free install (other than getting the tiny screws stuck between the battery and the rest of the assembly and needing to take my glasses off and peer intently with one eye into the iPhone - ah, the joys of ageing). But watch out for that little pressure contact - mine popped out and away when I was prying open the battery connector. Thanks folks for a great guide and also parts kit!

The guide was good but I found the youtube video more helpful, especially since the piece on that got moved on the video happened to me as well, so I was able to see how to put it back. It's been so long since my battery was properly working, that I am not sure if this new one is good. When I turned on the phone it was at 76%. I let it drain completely yesterday before charging it overnight. It's only half way through the day and it's down to 32%. Is this normal? I've not used it overly today. How often should a charge last for relatively average usage (checking emails, online a bit, texting)?

Could thenew battery be bad? I'm going to give it a few more days and monitor it.

The kit itself was pretty easy to use, the biggest issue being my eyesight isn't what it used to be, so thankfully had a friend to help. Just hoping the battery is ok and I don't have to do it all again.

Excellent guide. This is so easy to follow and do. It took approximately 15 minutes. I also watched a video on youtube where a guy was replacing the battery.


I did encounter the "Searching" problem on re-start. The phone could not find my service provider, but the fix was very simple, I just re-booted the phone and it was back to normal.

Very easy to do with help of the kit. I also replaced the screws but honestly i dont see the point. The philips screws are more fragile in my opinion. And as somebody else said, if your eyesight is bad, use glasses. The screws are so tiny!

Good stuff, great. A recommenation: Take a sheet of paper, put the stuff you dismantel on it, put a circle around it for each step and add the number. This will help during reassembly, especially the 2 different screws in step 4. Greetings from an old? (>60) German.

I followed the instructions but am unable to get the phone to power on unless it is connected to a alternate power source,tried rebooting phone, I still get the same result,

When I unplug phone it loses power and goes dark,battery meter on phone says it's fully charged! Does SIM card need to be reinstalled before powering phone on?

In general: Watch several videos before diving in. Wash your hands, and/or put on some snug fitting nitrile gloves. If your eyesight is not what it used to be, then use a magnifying light lamp or perform in a very well lit area. Re: Step 1 - At first glance, the two screwdrivers included in the kit look very similar; in order to avoid confusing the two, place a piece of colored tape on one of them. RE: Step 2 - push gently with two thumbs, but don't overdo it. The back plate will only slide forward 2mm - a very small space. Re: Steps 4 & 5 - Recommend using the kit box, or several small trays to set aside the 2 battery connector screws and pressure contact plate. These pieces are very small! The kit's screwdrivers are magnetized to hold the screws, but not the plate. Re: Step 7 - Some of the battery adhesive may come loose from the phone and battery, and ball up into a wad. An exacto knife can be used to gently excise any wadded up portions of adhesive.

Muy sencillos los pasos para realizar este cambio por una nueva batería, por ser un equipo ya viejo el iPhone 4s, me pareció muy buen precio los 25 USD por el paquete de liberación y el cambio de la batería, lo que más tarde por supuesto, fue encontrar el primer tornillo de la tapa, por más que lo quiero hacer con cuidado, se me cayó un tornillo que al final deje en el blister del paquete de liberación del cambio de los tornillos. en una semana diré si la batería me dio el performance que requiero para mi teléfono.

I can't believe I waited this long to swap my battery. The repair was easy using the kit with included tools. I had the phone apart and back together in about 10 minutes and I was working slowly so I didn't make a mistake. The only challenge was prying the old battery out. The plastic tool worked well, you just gently apply pressure as described in the guide. Now I am going to fix my old ipod.

I'm 57 and trying this without jewellers glasses was a mistake. The screws are TINY. I've worked on computers for years but never with screws THIS small! If your eyes aren't 20/20 get magnification for sure. The kit I got was from BattDepot and only came with one size of screwdriver. There are two sizes required. Dumb!! And the one screwdriver isn't magnetized so getting the screws back in has been a beggar. Good luck with your install. Mine's been more difficult than expected. (Should have bought the iFixit kit!)

My iPhone worked well except the fact that the battery was very used.

I change my battery by following these instructions and I succeed to disassemble and reassemble my iPhone without any difficulty. However, after having turned on my device, the cellular connection didn't work with the new battery. As written in the tutorial, I tried to restore the device using iTunes (in DFU mode and not).

After reviewing the steps I decided to follow this guy's advice and left the battery in.....one less item to possibly foul up. I don't know if it made it any faster (first time to open my phone, so nothing to compare it to) but I can say that my phone is charging for the first time in 6 months :D



1) This is doable but not easy, quick or without risk.

2) If this is your 1st time, the whole process can take >2 hours (half of it reading this fixit manual and notes, which I highly recommend!)

3) I highly recommend placing a large, thin clean white cloth on the table. This prevents screws from rolling around and you will clearly see anything falling out.

4) If you have them, use tight surgical (latex) gloves. This prevents you from greasing up contacts.

5) Have e.g. a big old egg box ready, so you can place the screws in order (and maybe write step/screw size on the side).

6) I bought my display from "Generic" on Amazon ($20.36). Screen works fine and tools were ok but not great (screw drivers do not withstand force needed to unscrew some).

7) I had my own 2mm Phillips screw driver and a 2.4mm flat (for the big screws).

8) Have a nice cold beer by your side! Good luck!

Sounds like this comment relates to a screen replacement, not a rear panel replacement. No way a rear panel replacement would take 2 hours - can be done in 2 minutes!

Jonathan Deamer,

I was paranoid about stripping the pentalobes - I used the ifixit pentalobe screwdriver TOGETHER with a layer of Glad Wrap (cling film or saran wrap for the non-Aussies) over the pentalobe holes - absolutely no problems. Guess it helps the driver head gain purchase?

After seeing the comments about trouble finding the carrier, I shut down the phone, did a soft reset (by holding the power and home buttons until it started and then shut down and stayed off), and removed the SIM. After the repair, I replaced the SIM and plugged it in to the charger. It started up and found the carrier (Verizon, as it happens) immediately. I would guess that only the soft reset made a difference, but I did both.

with a small driller, but I guess it is very difficult. Never attempted that myself on an iPhone.


There is no screw in Step 2?

Is the screw stripped or the head stripped?

I have used superglue on the screwdriver to remove a stripped screw, it would turn but not come out, with superglue I could turn and pull the screw out. May also work on a stripped head.


If you are careful, use a Dremel tool and a micro drill bit (sold where Dremel tools are purchased) to drill it out. Last resort kind of thing, good luck.

gregsrow, · Reply

This step needs a few more caveats.

The bottom screw on my phone was locked with some thread adhesive, and required more force to loosen it than I expected.

Even after removing the screws, the battery connector was rather firmly seated, and required a fair bit of persistent gentle prying with the opening tool before it came loose.

The ground clip came loose and nearly flew off while loosening the connector, so it would really help people if there were a warning on this step to watch out for the ground clip and make sure it doesn't bounce away.

The battery connector is attached to the battery. You're not going to completely lift it out and remove it. It pulls out from the socket you can see in step 5 picture 3. The pressure contact (little black and gold thing) will probably just slide out from under the connector. Not a problem.

In french: attention avant de retirer le contacteur de la batterie. La vis du haut tient "en sandwich" une petite pièce métallique noire et dorée. Cette pièce a pour but de faire contact de masse avec le dos de l'iphone quand il est refermé. Donc il ne faut pas la tordre. Quand les deux vis du contacteur sont retirée, attention au moment de débrancher le contacteur: cela va faire bouger cette pièce qui ne doit pas être abîmée ni tordue. Au remontage, il faut bien la remettre en place sous le contacteur de batterie: il est tout à fait possible de mettre d'abord le contacteur, puis de glisser la petite pièce au dessous pour qu'elle soit bien à sa place, le trou en face du trou de vis et du trou du contacteur. En remettant la vis, la pièce tient bien en place. Elle doit bien continuer à dépasser de manière a faire contact avec le dos de l'iphone.

Top screw didn’t move with iFixit Philips #000 driver. The metal is too soft and in the result the screw was damaged while still in place. Having nothing to lose I also tried #00 and #0. Any way to remove the stuck screw? I would gladly saw it off if I could.

Ok, I had to drill the screw to break it. It was very delicate and time consuming operation. But in the end the screw cap finally broke off and I was able to remove the battery!


The Liberation Kit Philips head screwdriver strips the battery connector screws! It stripped the ne 1.7 mm Phillips screw circled in red in the photo above. I was able to remove the other screw, then I lifted the battery connector off while the red screw was still in position and wound the connector around in circles while lifting upwards and managed to unscrew the stripped screw. Advice, find a decent philips heard screwdriver for the internal screws like the two found on the battery connector.

When reassembling, use EST tweezers to get align the pressure contact over the top screw hole. using the pointy end of a spudger to assist: put the point through top screw-hole on the battery connector, then through the pressure contact and into the screw-hole. this will help to keep the small piece in place while re-seating the battery connector. Leave the top hole spiked as such until the screw in the bottom hole is gently fastened. Remove the spudger and replace the top screw.

This picture needs to be greatly enlarged! The pressure plate sits directly underneath the battery connector, but cannot be seen here.

Got a big scare as the phone would not connect to the cell network at first boot, only WiFi. Shut it off and when it rebooted it seemed to work. WIll probably know in a day or so if everything works fine or if there are interference issues, etc.

This is normal ... removing the battery resets internal clock to start value and your provider doesn't accept that, hence no network.

Going online through wifi or manually setting date right corrects this after a reboot.

Bill McNamara,

The black ground contact needs still more "flagging." This is a simple metal strip that is attached ONLY by the 1.5mm (upper) screw. It will help if you look at it before you remove the upper screw. Notice the gold contact arm and point. That contact point must be in a plane above every other surface inside the device when you replace the battery connector, because it makes a ground contact with the metallic inner surface of the device back plate.

When I replaced it, I used the Pentalobe driver to line up battery connector and ground contact with the screw socket post. I then attached the 1.7mm (lower) screw loosely, removed the Pentalobe driver gently, and inserted the 1.5mm (upper) screw into the assembly. There is a tab on the ground contact that helps it align properly once pressure begins to applied. I completed driving the upper screw, pressing lightly with the spudger on the battery connector plate to make sure it was seated on the pressure contacts. Finally, I completed driving the lower screw.

Matt McCaffrey, · Reply

This is a hard step because the directions and pictures are not very clear. This might help:

1) Here you HAVE TO disconnect the battery connecter (the language is confusing).

2) This is easier than it looks, as you can simply lift the connector upwards from any angle (I rested my plastic tool on the antenna and gently lifted it up).

The photo suggests you have to pull the connector backwards (which would be hard), this is not true, it can be lifted up towards you (the pins go out backwards and upwards, you'll see).

Finally, don't confuse the "pressure contact" with the "pressure contact point". You remove the contact, the contact point (underneath) sits on the board. No need to worry about this.

After reassembly, the CELL CONNECTION WASN'T WORKING. You might need to slightly bend the contact in step 5 up just a little, so it will make contact with the metal back plate. Did that and it worked perfectly.

I found the plastic pull tab to be useless. Peeled pretty much the whole battery out from the left side. Used a probe to "break" a few strands of glue to help. Just watch the connector and ribbon cable in the lower left corner as you pry up so you don't crimp them or damage them.

DO NOT remove the battery unless absolutely necessary. If the battery is removed from the phone, DO NOT reuse it, ifixit does not seem to understand the importance of safely handling the battery

Tom Chai, · Reply

Tom you have never been so wrong. Removing the battery is the FIRST step ANYONE should do before repairing or attempting repairs on their phone. The iPhone has many different grounding points in the phone and having electrical current running to it poses a massive risk, especially with ESD (ElectroStatic Discharge). People, PLEASE make sure you remove your phone's battery FIRST before doing any repairs. Use a plastic, not metal, spudger, after unhooking the battery from the logic board, place the spudger along the right side of the battery NOT under the volume buttons, about an inch and a half lower (two roughly if a sim card is present) and start prying it up using the frame as the fulcrum, as you start to lift the battery from the adhesive make sure you slide the spudger farther under to get even contact so you do not damage the battery.

Prestige Computer Solutions,

Try a used plastic credit/gift card to apply gentle pressure to lift the battery out of the phone, the short edge of the card fits within the gap on the logic board side between the battery and video cables. You can also use it on the opposite side if there is room between the battery and iPhone frame. This has worked on all of the 4 and 4s models I've replaced screens on.

I offer an alternative image if interested.

Hello! My clients iphone 4s:n battery connector broke, when i tried accidentally take the battery out with a plastic tool from the wrong side.

Connector detached completely, so that the two middle ironcensors came with it and was stuck to the connector. When i screw the whole connector back to phone, it works with battery power, but the batterys downloading doesnt work. Are these two middle censors that are stuck in the connector exactly the ones that should be charging the battery? Do you know how i can fix this? I have already bought electrical conductor glue, but should the parts be cleaned somehow first? And how can i fix it, when the center metal sensors on the system board is also attached to the battery?

How can i clean out thiskind of part with windex? I have purchased almost all of the possible tools from iFixit and the electrical conductor glue i bought somewhere else. (http://www.ebay.com/itm/300915727408?ssP...)

Please, Please, PLEASE avoid using probing elements to try remove batteries. I have had dozens handed in to me with punctures and two that actually started smoking due to people trying to prise the battery out. DO NOT DO IT.

The best way I have found to remove the battery is this process;

1) Try remove it with the pull tab directly, some will come out, some will not. Do NOT use excessive pull force else it'll deform the battery and reduce the capacity.

2) If the pull test didn't work, then get a hot air gun on medium and warm up the area around the battery for about 30 seconds, focusing on the perimeter of the battery. If you see ANY popcorn'ing then you're too hot, you don't want to cook the battery.

2.1) Wait about 30 seconds for the heat to now wick underneath the battery to soften the adhesive.

2.2) Now try pull the battery up, the extra heat should have softened the glue that you can remove the battery without excessive force and without sticking objects under the battery.

Buy a cheap pair of digital callipers ($20 -$30) and it will be clear. You can then use them to measure all kinds of things instead of squinting with a ruler.


I bent the wire of the silent button on right top of the battery. Now the silent botton don't work. The wire on the bent is half-cut. BE CAREFUL when you put the new battery inside!

Was having a hard time getting the screws back into the battery connector. Read another tip online that helped - pushed the end of my phillips screwdriver into some soft candle wax which gave it just enough stickyness to have the screw stay attached to the screwdriver while I was moving it toward the hole. Thought I'd pass that along.

I did as wazzamagu did (and stated above), "My Pentalobe tool was slightly magnetized so I used that to bring the screws in for tightening with the Philips screwdriver." That made replacing the screws fairly easy. Thanks for all the advice on this page. It was not hard at all. Go slow and carefully, everything is smaller in there than I expected. The "searching" thing came up as it seems for most people, but just took a reboot and all is fine.

I had the same issue with "searching network". After resetting the network settings in settings it did work perfectly!

Took about 15 minutes. The only thing that was confusing was the reference to parts, using the partname, and I didn't know what they were referring to. So I had to figure it out by the photos. Slightly frustrating. Got it in and it worked. My problem then, was it kept SEARCHING and couldn't find my carrier. I followed everyones advice on here, plugged phone into my computer to itunes. then turned off network settings in settings, then turned them back on, and I got 3 bars. good to go.


Instructions were good and everything works fine after replacement. Needed to use a tweezer on the pressure contact on the top screw of the battery. Thanks

I swapped out the battery today. No real issues. Pretty easy task.

For the past couple of months, my phone had been dying very fast. I knew that my phone's battery capacity was getting quite low as this phone is older now, and is out of warranty. So I ordered a replacement battery about a week ago, and just installed it yesterday. The install was pretty easy, if you pay attention to where everything belongs. But my draining issue has not gone away. It stays charged a bit longer, my capacity is at almost 100%, yet it can't even hold a charge over night. I'm not sure what is causing this and would love any tips or stories from someone else!! Please help!!
