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.
    • 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.

  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.

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

  4. 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.
    • 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.

    • Heat an iOpener and apply it to a long edge of the S8 for about 2 minutes.

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

    • 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.

    • As you're waiting for the adhesive to soften, move on and read the following step to get an idea of where to pry.

  5. In the following steps you will be cutting through the adhesive around the edge of the rear glass panel. The adhesive on the rear case is laid out as seen in the first image.
    • In the following steps you will be cutting through the adhesive around the edge of the rear glass panel.

    • The adhesive on the rear case is laid out as seen in the first image.

    • The prying pattern as seen from the outside of the phone is as follows:

    • Thick portions of adhesive

    • Thin areas of adhesive

    • Avoid prying here, to protect the fingerprint sensor.

  6. Once the back panel is warm to the touch, apply a suction cup as close to the heated edge of the phone as you can while avoiding the curved edge. The suction cup will not make a good seal on the curved portion of the glass.
    • Once the back panel is warm to the touch, apply a suction cup as close to the heated edge of the phone as you can while avoiding the curved edge.

    • The suction cup will not make a good seal on the curved portion of the glass.

    • If the phone's back cover is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • Lift on the suction cup, and insert a halberd spudger, or opening pick, under the rear glass.

    • Due to the curved glass, you will be pushing up, rather than inserting parallel to the plane of the phone.

  7. Once you have the tool firmly inserted into the glass, reheat and reapply the iOpener to soften the adhesive.

  9. Slide an opening pick or the blade of a Halberd spudger down the side of the phone, separating the adhesive. Go slowly so that the tool doesn't slip out of the seam. If cutting becomes difficult, reheat and reapply the iOpener.

  10. Repeat the previous heating and cutting procedure for the remaining three sides of the phone. Leave an opening pick on each side as you continue to the next to prevent the adhesive from resealing.

  11. 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.
    • 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.

  12. Follow this guide to reinstall the back cover and replace the adhesive.
    • Follow this guide to reinstall the back cover and replace the 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.

  18. Prepare an iOpener and apply it directly to the battery for at least two minutes. Reheat and reapply the iOpener as needed.
    • Prepare an iOpener and apply it directly to the battery for at least two minutes. Reheat and reapply the iOpener as needed.

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

  19. 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.
    • 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.

  20. Slide the opening pick up the side of the battery to break apart remaining adhesive. Lift the battery out of the case. Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new 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?

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.

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

Good Survey - Ответить

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.

How complicated compared to my old S4 … what a joke
