Introduction

This guide demonstrates the necessary procedure to replace a defective battery in a Samsung Galaxy S6 Edge.

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.

  1. 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.

      • Do not insert the tool into the microphone hole or you could cause damage. Look for the outline of the SIM tray.

    • Press to eject the SIM card tray.

    • Remove the SIM card tray from the phone.

    First thankful sir that you have a good idea for people to creat like this.. I am very happy from your website its too good. All things i learn from your website thank you..

  2. We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener.
    • 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: https://youtu.be/16GkvjVyOJA It is much easier to do if you heat it from the other side.

    I wonder how many people actually wrapped in their iPhone into iOpener and put this "sandwich" into microwave??

    putinaspiliponis - Reply

    I know this is obvious, but backup your iPad with iTunes before you start. I'd also turn off your passcode if you have one.

    Laurie Higgins - Reply

    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.

    Not everybody has a microwave. You need to state how long and at what temperature in a conventional oven.

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

    • 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.

    whale13 - Reply

    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.

    Mohideen Rifay - Reply

    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 things....no 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 :-(

    I used a hot water bottle, works well as it covers the whole screen and stays hot for longer.

    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.

    • The iOpener will be very hot, so be careful when handling it. Use an oven mitt if necessary.

    • 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?

    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

    After did that with my own heat pad, the white paint got ripped off but luckily glass back cover did not break. So I scratched all white part of the back cover and now its all transparent.

    I used a purpose built heating device at 100 degree celsius. Lower temperatures didn't work.

    I used a blow dryer, attached my multimeter heat sensor to the back to monitor the temperature. At 54 degrees Celsius I could separate the back with a suction cup from my phone without damaging the paint.

    • 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!!

    • 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.

    I used a card like the ones people use to play poker or any card game with. Only one was needed to separate the back without any damage to the paint.

    Be sure to apply a decent amount of heat when removing the last bit of the rear glass, cracked the rear of my screen (only a small amount mind) trying too use too much force not enough heat for the last spot.

    • 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

    When I did my battery, the adhesive stayed almost 100% on the back glass and was still in good shape. What didn’t remain attached only lifted slightly and I was able to coax it back to its original location with tweezers. I didn’t bother to remove and replace the adhesive layer because mine was still good. I set the glass out of the way where it wouldn’t get dirt on the adhesive while I finished the battery swap. I added some additional heat (hair dryer) after reattaching the glass to make sure the adhesive made the best seal.

    • The motherboard is an ESD sensitive component and should be handled with care. iFixit recommends using a anti-static bracelet whenever handling components of this nature to avoid damage.

    • Grip the motherboard on both edges toward the top of the device.

    • Do not lift the motherboard all the way out in this step; the ribbon cable on the underside needs to be disconnected first.

    • Lift the motherboard up and away from the display, taking care not to put too much stress on the daughterboard ribbon cable.

    Better to remove the antenna connector from daughter board and keep the connector on main board, as You will planning to remove it you will need to take from it anyway.

    • Insert an opening pick underneath the battery and slide it across to break up the adhesive underneath.

    • Try your best not to deform the battery while prying. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.

    • Twist the opening pick to fully dislodge the battery and remove it.

    • 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.

    Hi Sam, in conclusion and reassembling is the heat pad (used at the appropriate step in reverse) sufficient to re-adhere the panels or should new adhesive be applied. If new adhesive is required, can you recommend a satisfactory product please.

    Cheers

    You should apply new adhesive when reinstalling your rear panel. You can use this 3M Double-Sided Adhesive Tape that we sell, or look around online for adhesive tape cut specifically for your phone.

    Achtung!

    Der Rahmen unter dem Akku ist an den verklebten Längsseiten nur ca. 5mm breit. In der Mitte befindet sich kein stabiler Schutz zwischen Akku und der Rückseite des LCD-Panels. Also besser wirklich nur die Ränder lösen und nicht mit einem Spachtel oder Ähnlichem hinter dem Akku herumhebeln, denn das könnte das LCD beschädigen.

    Oliver Edler - Reply

    Beachten bei Akku Einbau!

    Die Position des Akkus muss in Längsrichtung unbedingt anhand des Anschlusssteckers ausgerichtet werden und nicht an dem Kunstoffrand des Bodens. Das Flachkabel ist nicht flexibel und der Anschlussstecker hat kaum Toleranz (+- 1/10 )

    Das ist etwas knifflig, denn man sieht die richtige Lage nur, wenn die Hauptplatine in Position ist.

    Am besten, man überprüft das, bevor der Kleber am Akku angebracht ist.

    Wer den Fehler gemacht hat, weiß was ich meine. :/

Interesting but so difficult not worth doing! My A G S6 edge battery expanded in the night and pushed of the back. Fortunately I was awake and saw it happen.

My advice is not use Samsung phones too dangerous!

Good guide, but with one minor correction - the SIM card slot is on the volume button side of the phone’s upper edge, not the power button side. An important distinction, considering the potential damage one could do if they stick the pick in the wrong hole.

thx 4 this! it showed me it's not rly worth buying this phone off eBay with a battery that needs replacing. while I feel pretty secure that I could replace the battery using this (extremely well explained) guide, I don't rly feel like investing this much energy into something that could potentially further damage my phone, so the search continues to replace my note 4 that had the eMMC bug :/
