Use this guide to replace the battery in your Samsung Galaxy S6.

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

If your battery is swollen, do not heat your phone. If needed, you can use a dropper or syringe to inject isopropyl alcohol (90+%) around the edges of the back cover to weaken the adhesive. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you're not sure how to proceed.

This guide involves removing the rear glass. Removing the rear glass destroys the adhesive holding it in place. Follow this guide to reinstall the rear glass.

Insert a paper clip or SIM eject tool into the hole in the SIM card slot on the power button side of the phone.
  • Insert a paper clip or SIM eject tool into the hole in the SIM card slot on the power button side of the phone.

  • Press to eject the SIM card tray.

    • Don't press too hard or you may damage the SIM card tray.

  • We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener.

  • Place the iOpener in the center of the microwave.

    • For carousel microwaves: Make sure the plate spins freely. If your iOpener gets stuck, it may overheat and burn.

which temperature must be used for heating? Thx

I found you need to be very patient when using the iOpener. It's worth taking your time, giving the heat time to work on the glue. When I finally got the battery out, there were some strips of glue left behind that I just cleaned off with some isopropanol before installing the new battery.

By the way, I had to run the iOpener for longer in my microwave for it to get hot enough. When it was too hot to touch, I figured it was hot enough for the batteries.

I didn't find this to be as hard as I had built it up in my mind to be; HOWEVER, saying that I need to say years ago I was the local Nokia service center in my town. But many years ago right after they got rid of analog times. Yeah. A classic installer/repairer mistake when starting something they haven't fixed or installed before is picking up the instructions, flipping through them; maybe even reading a section that is new-then tossing the instructions over the shoulder. "I got this." This usually comes right before something major gets broke. And I can tell you when you try to do it yourself and then mess it up horribly then take it to the repair shop. Well we called that "I can do it myself" syndrome and charged extra to put back together what they brought in in the box. Now knowing all this - I can't stress this enough because I am stupid, stupid, stupid. COVER YOUR SCREEN IN CLEAR BOXING TAPE AND READ ALL THE INSTRUCTION BELOW THROUGH TO THE END BEFORE EVEN ATTEMPTING THIS FIX. Take my advise.

I didn't have an iOpener, so I used a wheat type heat bag. If you do this though, make sure you put a layer of plastic between your Mac and the bag, or you'll get condensation in places you don't want it.

I started out using the iOpener but switched to my wife's hairdryer. A heat gun or hair dryer proved to be much more convenient and is a time saviour. You can heat more and the glue becomes more fluid make the next steps with the opening picks much easier

Use a hair dryer! Watch this vid: It is much easier to do if you heat it from the other side.

Ther first time you heat up the iOpener for this repair when its room temperature I had to heat it up for more than 30 seconds. I remember I had to heat it up for around 45 seconds. However, after that when you need to reheat it again during the repair 30 seconds will be enough.

Hi, the microware have multiple power 1 to 9, what must be used ?



Cedric VINCENT - Reply

  • Heat the iOpener for thirty seconds.

  • Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional thirty seconds at a time.

  • Be careful not to overheat the iOpener during the repair. Overheating may cause the iOpener to burst.

  • Never touch the iOpener if it appears swollen.

  • If the iOpener is still too hot in the middle to touch, continue using it while waiting for it to cool down some more before reheating. A properly heated iOpener should stay warm for up to 10 minutes.

May I know the temperate limit about heating iOpener? (maximum 150 degrees Celsius?) thx so much.

yamayhuang - Reply

I had to heat mine up for more than 30 seconds. After 30 seconds on high it was only warm. It had to keep trying different times and checking it until it got hot. I think the initial time that I put it in for was over a minute.

DO NOT USE IN NON ROTATING MICROWAVE! It will pop a hole. I had it in for 45 seconds the first time. It wasn't very hot inside and I saw it started to leak on the paper towel I put under it. Just a fair bit of advice. I think I will just stick with the heat gun. Loud but useful.

I heated mine up for 30 seconds, tested, then again for 30 seconds. It felt adequately hot. Leaving it on the left side, per the instruction, for a minute did not loosen the adhesive. I ended up pulling the suction cup hard enough to shadder the old screen. Moral of the story, I don't think it gets hot enough safely to have an affect.

Travis Dixon - Reply

There is a clear problem here with the heating part using the iopener details are given. Whoever is testing them needs to make it clear - What temperature does it need to be? And for which phone models, because they differ in what's needed. It's only £10-15 for a laser guided temp sensor unit, and the designers/repairers should have one of those already for doing these kinds of repairs. Explaining half a repair, is worse than not explaining at all :-(

30 seconds sure isn’t cutting it… 45 didn’t get the screen of my iPad air 2 to budge either… even after resting on the ipad for 4 minutes.

60 seconds in the microwave, the iOpener burst.

I’ll get a new one and try once more with heating it 45 seconds and repeat that for 30 minutes like others have said here. If that doesn’t work it’ll have to be the heat gun.

  • Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.

  • Opening your phone will compromise its waterproof seals. Have replacement adhesive ready before you proceed, or take care to avoid liquid exposure if you reassemble your phone without replacing the adhesive.

  • If your glass is shattered, put packing tape over the entire panel to hold it together during the removal process.

  • Lay the heated iOpener over the rear panel for about two minutes to loosen the adhesive around the edge of the glass.

    • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

  • Shift the iOpener to heat the remaining section of the panel for another two minutes.

  • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

are there any option out there that allows you to heat the adhesive outdoors without any power plug?

John Joiner -

the way we do it at Get it fixed cellphone repair calgary is with a heat gun, wich is way easier than this, make sure to wear some gloves and dont worry to use to much heat as long as you point just to the back of the phone, (the back panel is thick enough to protect the logic board from over heat) instead of the usual blue plastic piece i sugest to use the thinnest metal razor knife and a business card so you can insert the business card and move it all around the frame, those blue plastic things are way too thick that will break the glass panel if you apply to much pressure

  • Once the rear glass is hot to the touch, apply a suction cup near the bottom edge of the glass.

  • Lift on the suction cup to create a small gap underneath the rear glass, and insert an opening pick into the gap.

  • Optionally, once the pick is inserted, you can add a few drops of isopropyl alcohol into the gap to help weaken the adhesive in the following steps.

If the rear screen is cracked/smashed, you will not be able to use a suction cup to remove it. The suction could would not seal because of the cracks. I tried masking tape, 3M shiny HVAC tape, and others, and the suction could would not seal to those surfaces either.

I ended up using the sharp point of the smudger to remove some shards of glass to get underneath the cover to leverage it up and out. Definitely use gloves and safety glasses if you have to do this.

Thank you for your comment. I needed to see this particular instance of what to do when the back cover was cracked. I was going to try to suction it with tape covering it. This saved me some heartache. You're an angel!!

Jessie Brooks -

  • Slide the pick along the bottom edge of the phone to slice through the adhesive securing the rear glass.

  • Afterward, it may help to leave the pick in place and grab a second pick as you proceed to the next step. Leaving the pick inserted can help prevent the glue you just separated from re-adhering.

  • Re-heat the rear glass as needed to prevent the glue from cooling and hardening.

Add Comment

  • Repeat the heating and cutting procedure for the remaining three sides of the phone.

  • Leave an opening pick under each edge to prevent the adhesive from resealing.

At this stage I didn’t use a plastic pick as I think they are too thick and will crack a screen that’s not already cracked. I used a stainless steel

I sesame blade which does a much better job of cutting through the adhesive. Just be careful not to insert it in too far. I sometimes put a mark on my blade to ensure it doesn’t go in too far.

  • Use an opening pick to slice through any remaining adhesive.

  • Remove the rear glass.

  • Use tweezers to peel away any remaining adhesive from both the rear glass and the phone's chassis.

  • Then, clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth. Swipe in one direction only, not back and forth. This will help prep the surface for the new adhesive.

  • Follow this guide to reinstall the rear glass.

You should note that the adhesive strip may need to be fully removed from the frame in order to proceed with repairs. The adhesive on my phone covered all of the screws exposed in the next step.

Sean Cruz - Reply

  • Remove the thirteen 3.5mm Phillips #00 screws securing the midframe to the phone.

Make sure you do not mix up these thirteen screws with a hidden 14th screw under the mid-frame chassis, on the left side of the headphone port, on daughter-board. This 14th screw is shorter than the other screws, so make sure you do not replace it with one of the longer screws. It will push up against the front glass and lift it away from the adhesive.

David Whyte - Reply

  • Firmly grasp the edge of the midframe assembly.

  • Lift up on the midframe assembly while pushing down on the battery to separate the midframe assembly from the rest of the phone.

    • While lifting the midframe, be careful to avoid snagging it on the audio jack or charging port.

  • You may need to heat and apply an iOpener to the edges of the display to soften the display adhesive if midframe separation is difficult.

i suggest to apply heat on the corners of the front screen to lose the adhesive a lil bit and push from the bottom back of the phone right where the wireless charger is because of the charging port

get it fixed - Reply

When grabbing from the bottom, you fun the risk of damaging the charging port and headphone jack. I would suggest starting from the top. This is because the two ports at the bottom slide down into the frame. There is also adhesive that will give you a little resistance.

Alex Philip - Reply

Step 18 is not correct, you have to start from the top. You can damage the charge port

On mine the adhesive actually tore away part of the colored film on the back of the screen glass rather than separating from it. I’m guessing applying heat to the screen corners first would help avoid this (I didn’t).

  • Insert a plastic opening pick between the case and the battery.

    • Be careful to keep the pick as flat as possible to avoid bending the battery, which may damage it and cause it to release dangerous chemicals.

  • Push the pick further in to separate the battery from the phone.

    • If the battery is too strongly adhered for the opening pick, place a warm iOpener over the battery to loosen the adhesive.

    • Alternatively, apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.

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

Do you have to remove the battery to remove the motherboard? I just need to remove the motherboard for soldering.

No, it is not necessary to remove the battery.

However, it makes it easier to handle the phone with the battery taken off.

I used a trick from a different phone tear down, but it really helps, slip a length of dental floss under the top edge of the battery, then with a back and forth action of the floss, you can slice through the adhesive and easily remove the battery, worked great on this phone.

  • Remove the battery from the phone.

  • Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.

  • To install a new battery:

    • Remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the phone, not directly onto the battery. The adhesive should go around the perimeter of the battery compartment, but not in the rectangular cutout in the center (which is actually the back side of the display).

    • Press the battery firmly into place for 5-10 seconds.

Question!? If the screen is barley cracked at the coner, (2cm) of the phone, would it shatter thru this process!? Please let me know ASAP!?

Yes the UK version is very well glued in. I recommend using a flat metal spudger and pushing it in from the bottom right side and then continue doing the same working up. This method seems to be the safest and only takes a minute or two

Samsung warrenties are rubbish.

What step are you stuck on?

Evan Noronha -

I've encountered phones where the IOpener was no match for all the adhesive. I succeeded by heating them with an iron that's made for shrinking monocoat covering around the wings of radio controlled model airplanes. You can get them at a good hobby shop for ~$15.00. It's shaped so you can heat around corners and comes with a sock to keep from scratching anything. That method always defeated the adhesive for me.

David Blythe - Reply

If you are using a heat shrink iron as David commented above, keep it in contact with the phone for the shortest possible time required to soften the adhesive. At their highest settings these irons can reach over 200 degrees C (around 400 F) which is hot enough to damage flat cables, and distort or even melt plastic components inside the phone.

mlewus - Reply

The recipe is quite good and easy to follow.

But you should buy the the adhesive film and use it to fix the body again because the old one you have to destroy to handle the screws.

This film you can by at Amazon for 7,50€ and it was delivered within 2 days.

Once you get to removing the battery there is some adhesive holding it in place. It is probably a good idea to replace this so the battery does not move around, I used a small amount of UHU all purpose glue.

DO NOT USE super glue as this damages the plastic covering of the battery.

David Foley - Reply

Just did this today. If I had to add anything, you need a LOT of heat, and a VERY thin guitar pick to get between the glass and the midframe. I had to get the back panel to around 100c before the adhesive would give way, a lot hotter than I usually need to get most things apart (75-80c is the norm). Be careful not to burn yourself whilst you're doing this. Also, a larger battery will fit in here! Apparently S7 batteries can fit in the S6, but do your research online before you attempt this.

Is this just an issue with the battery not being charged still or is there possibly something wrong with the connector on my motherboard?

Just swapped out my battery… took about half an hour for me too. I would recommend a hair dryer over the heat pad they give you. Put the hi dryer on high and steadily went over the back panel for about 3 to 4 minutes moving medium slow…. I used the adhesive that I bought for the phon that matches the frame, but t had to buy on amazon for it. Also, needed just a bit of double sided tape to put the new battery on in place.

Overall though it’s a great kit and instructions!!! Gonna have to do another Samsung 6 soon, but the cost for the kit andbatteries is way cheaper than anew phone or the $120 to have someone do it for me. Though I am technically very capable to do the repair, anyone should be fine doing it if they can use a screw driver and just take their time.

This was super easy to do. The kits on Amazon fit perfectly. Used my hobby iron and went around the edges for about 3 minutes set at 100C (212F) and everything came off real easy with no damage to anything. Took about 40 minutes to do, which included cleaning up the old adhesive and the phone before reassembling. Well worth the effort versus buying a new phone, the new battery is just like the day I bought it.

I also wouldn’t have bought this phone if I’d known how hard it is to do the routine maintenance of replacing the battery. Since this is rated as difficult, I was afraid to attempt it myself. I took a new battery and adhesive strips to a local repair shop, SecurePro in SLO, where someone who’s done this many times turned it around perfectly in under half an hour. No more range anxiety!

Cynthia Replogle - Reply

Wasn’t too bad- my only problem / tip (?)- the rear glass on my phone had semi-shattered, so prying the rear cover off caused a few more breaks in the glass- and crucially, the glass seperated from the opaque film backing rather than from the phone. meant having to remove the backing and glue. Which was fine- I didn’t mind having the rear glass broken before but now it is transparent! which actually looks super cool. Great guide.

Hugh Roche Kelly - Reply

Out of curiosity - I replaced the battery with the kit from IFixIt - production date of new battery was early 2018.

Battery is now used for 2 months - and has a capacity of close to 0. So it last for 1/4 day without any interaction; phone typically drops dead at around 40% of the battery. A reboot then shows 0% battery.

Has anyone seen similar behavior.

I’m wondering if replacing the battery jet again makes sense - or if all S6 batteries (even the replacment kits) are just crap.
