Use this guide to replace the battery in your Samsung Galaxy S9 Plus.

Opening the Samsung Galaxy S9 Plus will damage the waterproof seals on the device. If you do not replace the adhesive seals, your phone will function normally, but will lose its water protection.

Before disassembling your phone, discharge the battery below 25%. If your battery is swollen, do not heat your phone. 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.

You’ll need replacement adhesive to reattach components when reassembling the device.

  1. Switch off your phone.
    • Switch off your phone.

    • Use an iOpener to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes. You might want to repeat this step several times during the back cover removal.

    • The adhesive of the Samsung Galaxy S9 Plus is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

  2. In the following steps, you'll be cutting through the adhesive securing the back cover.
    • In the following steps, you'll be cutting through the adhesive securing the back cover.

    • The adhesive in the inside of the back cover is laid out as seen in the image.

    • You'll be slicing through the adhesive in the areas shown:

      • Thick portions of adhesive

      • Thin areas of adhesive

      • Avoid prying or slicing in this area, to protect the fingerprint sensor flex cable.

  3. If the phone's rear glass 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. Press a suction cup onto the back cover.
    • If the phone's rear glass 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.

    • Press a suction cup onto the back cover.

    • Lift the back cover's bottom edge with your suction cup, opening a slight gap between the back cover and the frame.

      • This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool. If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • Insert an opening pick in the gap and slide it to the bottom right corner.

  4. Insert a second opening pick and slide it to the bottom left corner. Insert a third opening pick at the bottom end of the phone. This opening pick stays there during the rear glass removal procedure to prevent the adhesive from resealing.
    • Insert a second opening pick and slide it to the bottom left corner.

    • Insert a third opening pick at the bottom end of the phone. This opening pick stays there during the rear glass removal procedure to prevent the adhesive from resealing.

  5. Start to slide the tip of the opening pick from the bottom left corner along the side of the S9 Plus. Leave the opening in its place after you cut the adhesive half way up the left side of the phone.

    • Leave the opening in its place after you cut the adhesive half way up the left side of the phone.

    • Slide the opening pick from the bottom right corner half way up the frame and leave it there.

  6. Insert a fourth opening pick at the right side of the frame and slide it to the top right corner. Slide a fifth opening pick along the left side of the phone to the top left corner.
    • Insert a fourth opening pick at the right side of the frame and slide it to the top right corner.

    • Slide a fifth opening pick along the left side of the phone to the top left corner.

    • Use the opening pick to cut the remaining adhesive under the upper part of the rear glass.

    • Don't open the phone all the way yet. The flex cable for the fingerprint reader is still connected to the motherboard.

    • Use the edge of a spudger to pry up and disconnect the fingerprint sensor flex cable.

  9. Remove the rear glass.
    • Remove the rear glass.

    • Before reassembly, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth before installing fresh adhesive.

  10. Remove the nine 4 mm Phillips #00 screws.
    • Remove the nine 4 mm Phillips #00 screws.

  11. Insert an opening pick under the right side of the plastic cover containing the NFC antenna and charging coil. Flip the opening pick sideways to lift the cover out of its plastic clips. Work your way around the plastic cover, prying up to release the remaining clips.

    • In the following step, only apply the spudger in the areas marked in red, which is where the battery adhesive is located.

    • Avoid this area. There's a gap in the mid-frame right below the battery, and you can accidentally damage the display through it.

  15. In case you have trouble to pry up the battery the adhesive may not be loose enough. You can apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive. Try your best not to deform the battery during the following removal 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.

    • Insert the flat end of a spudger at the top left corner of the battery where the flex cable is located and start to pry it up.

    • Work your way down the left side of the battery and loosen the adhesive with the spudger.

  16. Insert the spudger at the top right corner of the battery and pry it up.

  17. Remove the battery.
    • Remove the battery.

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

    • Before installing 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 at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place for 5-10 seconds.

Abschluss

To reassemble your device, follow these instructions in reverse order.

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.

For optimal performance, calibrate your newly installed battery: Charge it to 100%, and keep charging it for at least two more hours. Then, use it until it shuts off due to low battery. Finally, charge it uninterrupted to 100%
