Use this guide to remove an old or worn-out battery in the Huawei Honor 9.

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.

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%.

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

    • Heat an iOpener and apply it to the back of the phone for around two minutes. This will help soften the adhesive securing the rear glass.

    • You might need to reheat and reapply the iOpener several times during the rear glass removal.

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

  2. Secure a suction handle to the lower edge of the rear glass, as close to the edge as possible. 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.

    • 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.

    • Lift the rear glass with the suction cup to create a gap between the glass and the frame.

    • Insert an opening pick into the gap.

    • If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

  3. Slide the opening pick to the bottom right corner. Insert a second opening pick and slide it to the bottom left corner. Leave the opening picks in place to prevent the adhesive from resealing.
    • Slide the opening pick to the bottom right corner.

    • Insert a second opening pick and slide it to the bottom left corner.

    • Leave the opening picks in place to prevent the adhesive from resealing.

  4. Insert a third opening pick at the bottom left corner. Start to slide the tip of the opening pick from the bottom left corner along the side of the Huawei Honor 9 to cut the adhesive. Leave the opening pick in its place at the top left corner to prevent the adhesive from resealing.
    • Insert a third opening pick at the bottom left corner.

    • Start to slide the tip of the opening pick from the bottom left corner along the side of the Huawei Honor 9 to cut the adhesive.

    • Leave the opening pick in its place at the top left corner to prevent the adhesive from resealing.

  5. If the adhesive gets hard to cut it is likely too cold. Use your iOpener to reheat it. Insert a fourth opening pick under the top left corner of the rear glass.

    • Insert a fifth opening pick at the top right corner of the phone.

    • Slide the opening pick along the right side to cut the remaining adhesive.

    • Carefully lift the rear glass and remove it.

    • Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape.

    • After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.

  12. Apply an iOpener to the center of the display, to loosen the adhesive beneath the battery. The adhesive beneath the battery is very strong. You might need to repeat this process during the removal procedure several times. If heat does not work you can apply isopropyl alcohol (90+%) to the corners of the battery and let it penetrate the adhesive for several minutes before continuing. The flex cables under the battery are laid out as seen in the image. Try  to avoid prying in the marked areas to prevent damaging the cables.

  13. 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 right corner of the battery where the flex cable is located and start to pry the battery up. Work your way down the right side of the battery and loosen the adhesive with the spudger.
