Use this guide to replace the worn-out battery in your Samsung Galaxy S8.

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, take appropriate precautions. 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.

  1. 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

    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.

    Get yourself a cherry pit bean bag the size of your iPad. Heat it, put the iPad on it for 3 to 5 minutes or so, reheat the cherry pit bean bag, again put your iPad on it. Then heat the iOpener and start working. The cherry pit bean bag will have to be reheated several times, but it will soften the adhesive so you have less problems with the iOpener

    The heating can be done very effectively (and quickly) with 3d printer heated bed. Make sure the bed is clean. Set the temperature to 60c, (130f ) and put the ipad face down for +/- 10 minutes. Repeat as needed throughout the “gentle prying” stages.

    The iOpener did not work at all for me.

    I had to use a heat gun and bring the edges of the case up to ~200 degrees (used an infrared thermometer to measure) before the glue would weaken. This obviously superheated the metal frame, so I also had to wear gloves to handle the phone while prying the back off with the included picks.

    Repair instructions worked like a charm. Had to be patient with the iOpener and getting the screen off. I tried repeatedly without success until shifting the suction cup a bit to the left side where perhaps the glue had loosened up a bit more.

    Kyle - 답글

    The iOpener, in my opinion, is of no help. Many warnings to say “don’t warm it too much”, but the glue doesn’t melt if not warm enough. As a result, a complete waste of time and energy. In addition, too much liquid in it, so it doesn’t lay on the device on a sufficient surface. I took a hairdryer and it worked much much better.

    Step 1 should be: now that you have looked over the tools of this repair kit, take your ipad to the nearest repair store and let them handle it. Sure you will waste about $65 by purchasing this kit and the cost of the repair but you will not tear your ipad up and you will have at least 2 days of your life that you can spend time with your family.

    Just replaced the battery in my iPad mini LTE. Followed the Ifix step by step instructions and they worked very well. The only thing i would change is step 42. You do not have to lift the LCD connector from the logic board. So don’t. It’s an unnecessary step. Other then that all was good. It took me about 2 1/2 hours from start to finish but I took my time and I recommend you take your time also. Very exciting too finish doing it and see it come to life afterwards. Tested everything and everything still works

    My experience. I was replacing the screen which had been cracked and a little shattered in some places. The iopener is pretty much useless, so was the suction cup. The suction cup would probably be more useful if I was doing something besides the screen. Also you probably want the clean the screen before using it so it can get good suction. I used a hair dryer on high for a couple of minutes at a time (someone on this tread suggested that). I used my exacto knife and a razor blade to get into the adhesive. First the exacto to get the initial cut, then the razor blade to go a little deeper. Could have probably just used the razor blade, but the exacto has a little more finesse. I got the razor blade in and a little under the glass then I used the picks to wedge in. I didn’t want to risk anything using the razor blade too much. Used tape to keep the shattered glass together.

    My experience pt2

    Fortunately the shattering was mostly on the edges and most of it had adhesive on the back so it stuck together. Just take your time and work your way around following the guide to get the screen off. Have some goof off or goo be gone to clean the frame when putting the new glass on or putting the existing one back. (someone suggested that also, very good idea). Be careful of the LCD (you should know that). The cable on my LCD was pretty tight, so I propped it up while taking the cable cover off and when I put it back on I did the same thing. I just put a bottle on the battery and leaned the back of the LCD on that while attaching the cables and putting the screws back on the cover. Also be careful with the home button and the bracket on the back of it. I had enough old adhesive on left on the bracket that it stuck back to the new glass fine. So far only 12 hours in, so we will see how that holds up when the kids get at it.

  2. Heat the iOpener for thirty seconds.
    • 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.

    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 - 답글

    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 :-(

    assortedrubbish - 답글

    All phones/devices differ it’s unrealistic and unsafe to put a exact time/temperature needed to soften the adhesive. It’s really quite simple you warm the device evenly and in a controlled manner just enough to enable pry tools and picks to begin separating. Best tool in my opinion but again this is because I have experience is a hot plate and heat gun both of which are used at nearly the lowest settings and I can handle flat palming the plate for almost 10 seconds I leave the device to conduct heat until approx it’s about 110 at most 120 ish this will be plenty to soften all the adhesive if any problem areas I use heat gun while prying. Again you need go slowly and learn with a throw away phone

    Larry Bennett - 답글

    I also used a hairdryer. I used it on the low setting and I cut a piece of carboard to protect the rest of the screen. The iFixit tool and method is vert tedious and very time consuming in comparison. With the hairdryer method you can literally have the display apart in a few minutes. Using your other hand nearby the area you are heating it should be very hot but not enough to burn your hand. You only have to heat metal part of case near glass edge. If you have a cellular model then you need to be very careful because the black antenna area is plastic. So less heat and work your way up in adding heat just enough to separate around the area but not so much you melt the plastic!

    iOpener was the worst part of the kit. Followed directions for :30 in microwave and took 4 trips to the microwave to loosen adhesive on left side of home button. I thought I was figuring it out and it was working well… even set a timer to wait 10 minutes between heating it up. Was on the right side and was on my 12th heat up when it exploded in the microwave. My only tip is that if you set it clear side up, as soon as you see any bubbles or boiling in the liquid, STOP! If you put a pot holder over the iOpener and press slightly to make good surface contact, that seemed to help. I finished heating with a “Corn Sack” that held heat better than the provided iOpener.

    breadandbits - 답글

    The iOpener is, well, sort of silly. I used it for a while by immersing it in a pot of water regulated at 180 F, which worked, but I ultimately found it far faster to use a hair dryer. I do have an inexpensive IR thermometer which seemed to indicate that the adhesive softened sufficiently when the outer surface of the ipad display edge registered about 140 F. That said, the reflectivity of the outer surface is probably not suitable for reliable temperature indications with an IR thermometer. Just be patient. If you don’t have an IR thermometer, just heat the surface until it is almost too hot to the touch.

    Also note the instructions are VERY different for the WI-FI vs. the Cellular version when attempting to release the adhesive along the bottom (home-button) edge. In one case (on left side) you are to cut towards the center, in the other case you are to cut away from the center. I ended up cutting the right-side cellular antenna cable because I didn’t pay close enough attention here.

    The iOpener was a good idea but it just didn’t work. I used the heat gun on low and got it off in about 7 min. 30 min to clean off the excess adhesive. The directions stopped at removing the battery. What the !&&*??? is there a trick to plugging in the battery. Mentioning the need to seat the loudspeaker assembly and the NFC antenna - charging coil would have been helpful. Also, directions on seating the adhesive for the battery. Finally, directions on placing the seal would have been good. I ham handedly got it but needed to use the added adhesive that was sent with the kit. Overall took about an hour. I’m kinda psycho over making sure all the old adhesive was removed. Used the heat gun to reseat backing. worked great! Need to revamp the directions with items above but the kit had everything (except heat gum) and things I didn’t need.(likely to cover other installs.)

    Our issue was that a small gap would open when using the iOpener, but not large enough to get spudger or opening picks in there (also tried hair dryer but same result). Luckily as a guitar player I had some very thin nylon picks that we were able to get in there, which opened up a large enough gap to get the spudger and opening picks in. From there, we were able to heat the other sides and guide the spudger around the entire edge to get the back glass off.

    First we used a Dunlop nylon .38 mm guitar pick, then a .60 mm pick, and that allowed us to get the spudger in.

    This is by far the hardest part of any tutorial that requires you to open the Samsung. The iOpener is totally useless on my opinion (it doesn’t get warm enough). What I did instead is use a hairdryer but it took me time before I could get the adhesive soft enough. Especially since I was not able to measure the temperature of the phone will warming it. Also I think that the halberd is not thin enough so I used a radiology sheet (don’t know the right word in English) to get into the phone and it was much more effective and time saving. Thank you for the tutorial and good luck !

    • The fingerprint sensor cable connects the phone to the rear glass near the main camera. The cable is very short and should disconnect as the rear glass is removed.

    • As you lift the glass, peek in to be sure the orange cable with a blue connector has disconnected.

    • Use the opening picks to slice through any remaining adhesive and open the phone slightly.

    • If the fingerprint sensor cable seems snagged or stays taut do not open the phone any further. Disconnect the connector with the point of a spudger before proceeding.

    • During reassembly, in order to reconnect the fingerprint sensor cable, first angle the back cover into position until the cable connector lines up perfectly over its socket. Then, use the flat end of your spudger to gently snap the connector into place by pressing it straight down.

    • Remove the glass from the phone.

    For reassembly, if the fingerprint scanner is removed from the back cover: it’s much easier to place the fingerprint scanner in the small compartment on the back of the phone, connect it and then finally put the replacement back cover on. The adhesive on the inside of the back cover will get connect to the fingerprint scanner and hold it tightly.

    The NFC antenna and coil assembly might get stick to the back cover due to adhesive spreads while trying to pry the back cover to open the phone. Take a look inside to ensure the assebly has not got sticked. If so, try using a credit card like plastic to get it peeled of from back cover without breaking the assembly always paying attention to the fingerprint sensor as well.

  12. To install a new back cover:
    • To install a new back cover:

    • Use tweezers to peel away any remaining adhesive from the phone's chassis. Then clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to prep the surface for the new adhesive.

    • Peel the adhesive backing off of the new rear glass, carefully line up one edge of the glass against the phone chassis, and firmly press the glass onto the phone.

    • Follow this guide to reinstall the old back cover, or to install a back cover without pre-installed adhesive.

    • Be sure to turn on your phone and test your repair before installing new adhesive and resealing the phone.

    • If desired, you may reinstall the back cover without replacing the adhesive. Remove any large chunks of adhesive that might prevent the back cover from sitting down flush. After installation, heat the back cover and apply pressure to secure it. It won't be waterproof, but the glue is usually more than strong enough to hold.

    • You may also need to transfer the camera bezel to your new part. If that's the case, follow our camera bezel replacement guide.

    Hi,

    Must the 3 screws to the left of the battery be removed? I find that the NFC antenna/Charging coil is adhered onto both sides and can easily peel off. But of course, the 8 screws at the top must come off in order to disconnect the NFC antenna/Charging coil for replacement.

    • Use an opening pick to pry up the battery from the bottom.

    • You will be prying against the case directly above the daughterboard and antenna cables. Pry carefully to avoid damaging either of these components.

    • You may need to reheat and reapply the iOpener repeatedly to further soften the adhesive. The adhesive is tough and it may take a few tries to get the pick started under the battery.

    • Try your best not to deform the battery during this process. 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.

    Very frustrating process. Not a kit problem, but the folks at Samsung must be a sadistic bunch to use so much adhesive to glue in a battery, No success removing yet after numerous reheatings. Cracked back cover, so proceeding with additional caution due to batter location. Cracked board below the battery would be a disaster.

    Bruce Ward - 답글

    Success in removing the battery after about 7 reheatings. To reassemble, I had to remove the fingerprint sensor in order to fasten the circuit back to the board. Wasn’t a big deal. Reused the cracked back cover since I always use a protective cover and waterproofing isn’t an issue for me.

    Overall, I’m satisfied with the kit and the instructions. I just must have been too aggressive when dislodging the adhesive from the back cover.

    Bruce Ward - 답글

    If you have removed the front glass already, the process is a lot simpler. You can take a hair dryer and use it close to the back of the battery for just a few seconds, then use a combination of dental floss and the opening pick to pry the battery out.

    Damien - 답글

    I could not get a good angle with the pick to pry out the battery. I used the angled tweezers instead, although you need to be very careful not to puncture the battery. I inserted one tong of the tweezers along the bottom edge. I aligned the tweezer tip so it was flat against the front of the phone, parallel to the battery. Then I twisted the tweezers so the tip of the tong slipped under the battery. And I pulled the tweezers away from the front, continuing to twist the tip to keep it under the battery as I pulled the battery away from the adhesive. That worked quite well.

    Derek Snell - 답글

    The dental floss trick works! So much easier to ‘floss’ out the battery than risking puncturing the battery.

Who are these geniuses that engineer a cell phone that requires complicated surgery in order to replace a faulty or dead battery? Really? And this POS costs the yuppified zombies how much?

Joseph Kennedy - 답글

Mate, check a term “planned obsolescence” on wikipedia. Even if 1/50 of people won't replace a battery but buy a new Samsung, it is a 1 extra cellphone sold. It was designed on purpose hard to remove.

to make phone sistant and if you take how much thinks are in new phones of course they are complicated its same as new cars sorry but new technology is more sophisticated

Mine was stolen, it would be gone forever if they were able to pull out battery right away. But since I was calling and sending “play alert" commands through find my phone server, thieves were tired of it and left it on a sidewalk wrapped in paper and a t-shirt.

What type of adhesive do you use to stick the phone back

Hi! In our store you’ll find a rear cover adhesive strip for the S8. In the event that that’s sold out, we recommend using Tesa Tape—the 2 mm width should work well for this repair.

Will the phone still be water resistant after this ?

Thanks

aperret - 답글

This was wild. I hope I don’t have to use this knowledge for awhile. Why doesn’t Samsung just tell you to send it back and they will fix it for the price of a new battery? If I pay $800-$1,000 for a phone that I can’t change the battery on after a year or two, I’m going to be !#^&@@ at Samsung. Should we all complain to them about making this service available or having them advertise the lack of battery changing before a customer buys it?

that’s the issue. Like Apple, Samsung want you to buy another new phone every year instead of replace the battery.

Same issue, i sent my S8 back to Samsung 15days ago and still waiting for my f****** phone.

Pietro Ferracini - 답글

This process did NOT work for me. I purchased the kit and spare battery thinking it would be as easy as the video shows. However, after multiple attempts and several different hot pads later, the cover did not budge AT ALL. Now, I’m stuck with a kit that didn’t work and a battery (not even a Samsung replacement battery like the site stated), and nothing to show for it. Not being able to replace any battery in any electrical device on your own is just a poor engineering letdown, especially in such an expensive phone.

Michael Pakosta - 답글

There are versions of phones with waterproof battery compartments and certainly they could maintain their ability to control waterproofing the product of they still redesigned the access to the back cover via a more robust removable rear cover with gasket.

But with rear main cover more secure with screws possibly?

I'm not going to spell out how to tell them to make their phones, but maybe they might consider how users want to have the ability to change the battery themselves, and maintain the control of the device without sending it to a repair site for some time period.

Think of all the professional customers, besides all the soccer moms, students and retirees who they might dismiss right away.

Military & Government Officials, maybe even Senior Company Executives and tech companies that use these for everything from email and texting to secure encrypted NSA stuff.

Make it so they can be field repaired with a fresh battery seems like a no brainer?

That's my 2 cents!

Michael McGarghan - 답글

if battery deteriorates to a very low level, say, just last 1 hour after recharge, and it’s under warranty, can we send it back to Samsung for free repair?

chasun - 답글

Just remember, if you replace someone else battery and the phone explodes, you are liable. It’s advisable, if you’re not a bonded repair person, it’s not recommended that you change this battery. If you are doing it for yourself then take all precautions and insure the battery the correct replacement and you follow all removal and install direction specifically. If you don’t the results could void your Warranty or worse explode and injure you.

bgdn.soare - 답글

Thanks for the questions!

1. In theory the phone could still be water resistant, but I definitely wouldn’t expect that unless it was repaired by a professional—even then I’d still be pretty careful. In my experience it’s really easy to compromise ingress protections during a repair, so I generally just assume that my repairs are no longer up to the same water resistance standards as they were before.

2. We test our batteries to make sure they’re up to OE standards. If you aren’t getting close to the same life as you were with your original battery, contact our support team.

Good luck with your repair!

Adam O'Camb -

Replaced battery and a severely cracked back panel for a total of about $70 (750 NOK).

Less hassle and much cheaper than getting a new phone.

The glue holding down the battery is easily softened with some isopropyl alcohol.

A little warning: The NFC Antenna and Charging Coil Assembly has a rubbery feel to it. This substance does NOT like isopropyl alcohol and will disintegrate if you accidentally get some on there. It shouldn’t really matter much, but better keep the alcohol away from it.

After heating up the adhesive to the battery, it is a lot easier to go from the top where the battery connection is with your halberd spudger and just push it under the battery until it releases. Took me 2 minutes to heat up the adhesive then maybe 10 seconds to remove the battery from the case using the sponger. Also i gave up on the iopener and started using a hair dryer, worked way better.

mike howell - 답글

I’m heating with a hair dryer and it won’t budge. How long did you heat it? How hot is too hot?

Matthew Ellis -

There is a lot of adhesive on the back cover at the bottom of the S8, it goes about 1.5” up - its a lot of area to get through. Go very easy and make sure the adhesive is well softened with heat. You can go deep under the cover with whatever thin plastic tool you are using to separate the cover since theres nothing to damage in the area - but if you go too fast or pry too hard here the cover will break.

Aftermarket covers are very cheap (likely not gorilla glass), so it may just be better to be prepared to replace it if your original plan was to only replace the battery.

Paul G - 답글

After an hour of iOpener’ing and suction cupping I now have a completely shattered back glass piece.

Picks, halbread, none of the tools included were thin enough, or strong enough to get into the seam opening. Further pulling on the suction cup shattered the entire back glass.

Waste of $80.

Bob Peachey - 답글

Hi Bob,

I’m really sorry to hear about your repair! The back glass for Samsung devices are notoriously difficult to remove due to the adhesive. At this point, you got past the hardest part of the repair! The fix is still salvageable with a replacement back glass, which can be found for a reasonable price.
