Introduction

Use this guide to bring life back to your iPhone 6s Plus with a new battery. For optimal performance, calibrate your newly installed battery: Drain it below 10%, then charge it uninterrupted to 100%.

This guide instructs you to detach the front panel assembly; this is intended to prevent damage to the display cables. If you feel comfortable supporting the display carefully while peeling the battery out of the iPhone, you can skip the display removal and go directly to the battery removal steps.

You can also use this guide to replace the battery connector bracket.

Video Overview

Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
  • Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

  • Power off your iPhone before beginning disassembly.

  • Remove the two 3.4 mm Pentalobe screws on either side of the Lightning port.

Make sure you use the correct screw driver tip to remove these screws, which for the iPhone 6s Plus is the P2, otherwise you may strip the tip of the screw making it 10 times harder to remove. If once the screw is lose, it will not come off, use a magnet to remove it.

If I do it by myself, will it damage the water resistant strip?

I know iphone 7 have it ,but I am not sure 6s plus have it.

Ganqian Zhu - Reply

iPhone 6s has an adhesive gasket under the display, similar to the iPhone 7—however, it doesn’t add much in the way of waterproofing since the 6s has non-sealed openings in other parts of the phone. Water resistance on the 6s is primarily internal (seals around the logic board connectors, etc.). It may still be worthwhile to replace the adhesive on the 6s in order to help keep the display firmly seated so it doesn’t move/wobble at all under pressure, but the phone will continue to work fine whether you replace the adhesive or not.

Jeff Suovanen -

Opening the display on the 6s Plus separates a thin strip of adhesive around the perimeter of the display. If you prefer to replace the adhesive, have a set of new adhesive strips ready before you continue. It's possible to complete the repair without replacing the adhesive, and you probably won't notice any difference in functionality.

My cracked screen prevented the suction cup from sealing. SOLUTION: With a piece of clear packing tape across the screen, the suction cup will seal and pull.

Jim Cowles - Reply

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case. Pulling too hard may damage the display assembly. Apply just enough pressure to create a small gap between the display assembly and the rear case.

I had a shattered front glass panel so I could not get the suction cup to seal properly. I tried a couple of different ways to get good suction but to no avail. I eventually used a Stanley knife to pry up the corner so I could get the spudger into the opening.

A really high quality packing tape over the entire screen will usually be enough to use the suction cup on a shattered screen.

I used a suction cup on each side to provide counter traction. I braced the iphone between my knees and pulled apart while my helper inserted the spudger

jkanne - Reply

This was by FAR the most difficult part of this whole thing. I confess the spudger was not cutting it so I used a butter knife to get into the small opening first, then used the spudger to go around the screen.

Julie Sanchez - Reply

Hey everyone, if you never have done this part before be aware there is an extremely strong adhesive around the lip of the screen and once again is extremely strong. I had to get a friend to insert the pry/pick into the small gap while I used one hand to brace the phone down and the other to pull the suction cup without it digging into my hand. Go slow, it took me 5 tries because I didn’t realize how strong the adhesive was.

bartmistrot - Reply

I also had a badly cracked lower screen - that glass was actually threatening to pull off the phone in chunks during this step, even with packing tape. Resorted to @j2arch’s tip and inserted a utility knife vertically into the seam between the display and phone body. Was able to lever the glass enough to get the spudger in there.

The safest place to pry from is the notch in the front panel above the headphone jack. While still maintaining pressure on the suction cup, insert the flat tip of a spudger into the gap, directly above the headphone jack.

This was by far the hardest part of the repair for me. Getting leverage while finding a way to prod with a spudger is a challenge in coordination. I used a second spudger with point holding the phone down by the headphone jack, with the other end of the spudger anchored to my desk.

Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel as a hinge. Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone. Don't open the display more than 90º—it is still connected to the top of the phone by the display, digitizer, and front camera cables which can tear easily.

When putting the new battery in, make sure to line up the plug and not to the top of the battery… our battery was smaller so the plug would NOT have lined up if we used the top of the battery. ALSO, the plug was NOT 90 degrees so we had to finagle the plug. Also, make sure there is a clear CLICK when you plug in the connector or it may not work. Ours went in but guess didn’t go far enough so we had to take the screen off and push it harder until we heard the “click” then it worked fine.

I just changed my battery and also left the screen attached. I was lucky enough to get all 3 adhesive battery strips out clean so I didn’t have a struggle with the battery coming out. If I was going to need to get rough with it I was going to take the screen off at that point.

Use a plastic opening tool to disconnect the digitizer cable by prying it straight up from its socket on the logic board. When reconnecting the digitizer cable, do not press the center of the connector. Press one end of the connector, then press the opposite end. Pressing in the center of the connector can bend the component and cause digitizer damage.

Remove the display assembly. During reassembly, pause here if you wish to replace the adhesive around the edges of the display.

You need to clarify where exactly these "adhesive strips around the display" are, what they look like, and where to purchase new ones from.

Anthony - Reply

You can see what they look like in this blog post. Hopefully we'll have replacement adhesive strips available in the future, but right now I don't know of any suppliers. Your phone will work fine without replacing the adhesive—if I had to guess, I'd say it's there as a little extra insurance against display wobble now that 3D Touch has users pushing harder on their phones.

We now have a detailed guide for replacing the adhesive strips, and we should have them in stock soon. The guide has been updated to reflect this.

  • Peel back the tips of the three battery adhesive strips along the bottom edge of the battery.

OK - second most challenging part of the swap. TAKE YOUR TIME! It is hard to pull the strips out without getting them caught on the metal edge parts inside which can tear them, but do them one at a time, pull slow but steady, and as it stretches, grab the tape closer down near the body of the phone. You will not believe how far these things can stretch!

I was successful with getting 2/3 of them out but the one closest to the guts - the first one I tried to hurry - broke off. I got the other two out then needed to use a credit card to get up & under to loosen the battery. Another video I saw showed slightly warming up the back of the phone using a hair dryer set on low which would loosen the adhesive, but I did not do that. I was able to get the battery up far enough to use the tweezers to grab the adhesive and then pull it out.

Julie Sanchez - Reply

I’m absolutely stuck here. I don’t see the adhesive strips at the bottom of the battery. I only see the flat cable that wraps around the bottom of the battery, which is now separated. I don’t think it was supposed to separate like that.

Gather the ends of all three adhesive strips in your hand.
  • Gather the ends of all three adhesive strips in your hand.

  • Try to keep the strips flat and unwrinkled during this procedure; wrinkled strips will stick together and break instead of pulling out cleanly.

Gently pull the battery adhesive tabs away from the battery, toward the bottom of the iPhone. To avoid tearing the adhesive strip, be careful not to pull against the battery or lower components. Pull steadily, maintaining constant tension on the strips as they slip out from between the battery and the rear case. For best results, pull the strips at a 60º angle or less.

    • The strips will stretch to many times their original length. Continue pulling and re-grab the strips near the battery if necessary.

  • Hold down the battery with one hand as you pull, or the elastic strips may fling the battery from the phone once they're separated from the rear case.

Use a set of curved tweasers to pull each strip clear of the bottom left corner of the battery. Then the strips will pull out alongside the battery and the frame almost effortlessly. Do this for each strip and your battery should almost fall out.

I found it better to pull one strip at a time

John Parker - Reply

Do them separately or they will probably rip like mine did :(

Christopher Eccles - Reply

Pulling them separately is a good idea especially if it’s your first time. My middle strip tore at the beginning and I had to pry the battery up and then I was able to remove the remaining strip of adhesive. While prying the old battery in an upward angle it did start to bend I believe I achieved a 35 degree angle

Gregory - Reply

Definitely agree one at a time - see my comment above for more detail. Also possible to slightly warm the back of the phone first using hair dryer set on low. This loosens the adhesive if for some reason you break a strip off & have to pry the battery out (CAREFULLY)

Julie Sanchez - Reply

If you successfully removed all three adhesive strips, move on to the next step. Otherwise, you will need to pry the battery from the rear case. Prepare an iOpener and apply it to the back of the rear case, directly over the battery. Alternatively, you can apply heat using a heat gun or  hair dryer.

  • After about a minute, flip the phone over and use a plastic card to break up any remaining adhesive behind the battery.

    • Do not insert your card in the area between the volume down (-) button and the top edge of the battery, or you may damage the volume control cable lying underneath.

    • Do not pry against the logic board or you may damage the phone.

    • Keep the card as flat as possible to avoid bending the battery, which may damage it and cause it to release dangerous chemicals or catch fire. Do not use any sharp tools to pry at the battery.

  • Alternatively, a piece of dental floss may be used to separate the battery from the rear case. A stronger alternative to dental floss is an unwound guitar string, such as a 0.009 E string from a 12-string set.

  • Thread the floss or string behind the upper battery corners, bring the ends together, wrap them around a folded cloth, and pull evenly.

Remove the battery.
  • Remove the battery.

  • When installing the battery, refer to this guide to replace your battery's adhesive strips.

  • Perform a hard reset after reassembly. This can prevent several issues and simplify troubleshooting.

I recommend putting the battery in place BEFORE putting the new adhesive strips to make sure you know for sure that the battery connector lines up with the socket. I ended up with a battery wire that was just a bit too long and I mounted the battery way at top of the pocket (big mistake). Even after moving the battery down, the connector wire was still a little too long, so I had to connect the battery and shove the wire between the battery and logic board as much as I could. Checking the battery beforehand could save some adhesive strips from going to waste.

so few comments on this one?!

has any/many done this without the adhesive strips.. and was it ok?

sarah - Reply

If you mean the battery adhesive strips, sure—you can put a piece of double-sided tape down the back of the battery, and it probably won't move anywhere. There's not much room for the battery to move anyway. Use the adhesive strips if you want to do it right—but, if you're in a bind and you just need the phone working, you can skip the strips. And you can always open the phone back up and add the adhesive strips later.

If you mean the adhesive gasket around the display, the answer is pretty much the same—It's better to have it, but it doesn't hurt anything to put the phone back together without it.

Ezequiel Braunstein - Reply

Reassembly of the display to the chassis was a terrible ordeal until I realized that the front-facing camera connector and sensor cable connector cables had changed position in the 3-cable stack. This is possible--try it yourself:

Follow the two disconnected cables back to the display.

Swap them by tucking the smaller connector cable UNDER the bigger connector cable. You can do it because the angle that they exit the display lets them lie either way, on top of the other or under it.

You'll know immediately when trying to re-attach the connectors because the big connector needs to be the second (middle) one. Otherwise the cables can be hooked up with a lot of fiddle but they won't fold to fit under the cover..

The battery adhesive -- my case used to get hot until i changed the batt. Two-sided tape (like carpet tape) might not let heat shed betweenor or through the strips. Using two-side non-specifc tape in wide stripsfrom a roll? It makes me wonder about heat-managing properties of official batt tape.

Ned Bedinger - Reply

The old battery blew up on me while replacing, because the battery adhesive strips tore. I didn't have a plastic card to unstick the battery, so I had to bend it. That's why it blew up, so be careful guys, because I absolutely didn't expect that. There was lots of smoke and I burned myself a little bit.

I thought my phone will die after that, but I connected new battery and everything works fine.

Wow! That was awesome. It's amazing how easy things can be when they are designed to be replaced! One note though, when I was draining my new battery, at below 10% it would not play sound. I could not play music, or hear phone calls, I could however be heard. After having opened my phone so recently I was worried a connection had come loose or been missed entirely. Once charged to 100% everything behaved as expected. I am not sure if that is normal or not. I could totally understand restricting power use at those levels, but does it? I didn't "enter power save" not knowingly at least.

Very straight forward instructions. Easy to follow; video helped as well. Took me about 1 hour to complete. Phone is charging now. Looking forward to see how the new battery performs. Thanks very much for this site and to all contributors! I like fixing things myself. 11/19/17.

Just got done with my first iPhone battery replacement. Took me about an hour. I think the hardest part for me was getting the screen popped open enough to get the spudger in there. I ended up using an iOpener to warm the adhesive a little and it was a little easier to open enough to get the spudger in there. I also used the plastic scalpel tool from the Pro TechToolkit to cut the adhesive loose before shoving the spudger in there.

Hi,

I followed this tuto and I successfully changed the battery on my iPhone 6 S Plus without any difficulty. But, after then change, touchId feature does not work anymore. Main button is working fine, only touchId feature is faulty: I have a message saying that touchId feature will not be available on the phone.

I wonder if the fact that I disconnected the touchId connector (part of the 3 screen connectors), and reconnected it at the end, may act as the screen itself was changed. Some messages on forums tell that in this case, the iPhone refuses to reactivate touchId feature.

If someone can help it would be great.

Don’t be as stupid as me and follow the guide at the step 23. It’s really difficult to pull all the tabs together, better try it to pull out a single one and then go on with the next one.

There should be large red bold letters in this procedure telling you to make sure the battery is not connected when re-connecting the display cables.

I blew the backlight circuit on the motherboard.

I had the battery connected when plugging in the display cables.

Power was not on so it did not occur to me that it would be a problem.

Expensive mistake.

The problem that lures you into this trap is that you need to position the battery to align with the battery connector when re-installing the battery.

To make sure it is aligned properly, the natural thing to do is to plug in the battery connector.

But then you can forget that the battery is connected when you re-attach the display cables.

If I were to do this procedure again, I would not even disconnect the display at all. It is not necessary when replacing the battery.

Same thing happened to me. display now dead. had it done at the local gadget /phone repair store but they couldn’t fix it.
