Xiaomi Redmi Note 8 Battery Replacement

필요한 것

  1. Xiaomi Redmi Note 8 Battery Replacement, Heat the rear glass: 1 단계, 이미지 1/1
    • Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen the adhesive underneath.

    • 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. Xiaomi Redmi Note 8 Battery Replacement, Insert an opening pick: 2 단계, 이미지 1/3 Xiaomi Redmi Note 8 Battery Replacement, Insert an opening pick: 2 단계, 이미지 2/3 Xiaomi Redmi Note 8 Battery Replacement, Insert an opening pick: 2 단계, 이미지 3/3
    • Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.

    • If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.

    • In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap you created.

    • Slide the opening pick to the bottom right corner to slice the adhesive.

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

    • The battery is secured to the rear case with two pieces of stretch-release adhesive.

    • Use a pair of tweezers or a clean fingernail to peel down both battery adhesive pull-tabs to un-stick them from the bottom edge of the battery.

    • Don't jab the battery with any sharp tools. A punctured battery may leak dangerous chemicals or catch fire.

  18. Xiaomi Redmi Note 8 Battery Replacement, Remove the pull-tabs: 18 단계, 이미지 1/2 Xiaomi Redmi Note 8 Battery Replacement, Remove the pull-tabs: 18 단계, 이미지 2/2
    • Grab the right pull-tab with a pair of tweezers or your fingers and slowly pull it away from the battery and towards the bottom edge of your phone.

    • Pull hard enough to maintain tension on the strip, but don't force it. Give it plenty of time to stretch and un-stick from under the battery.

    • Don't press down on the battery. Hold the Redmi firmly by its sides.

    • Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.

    • Pull at a low angle so the strip doesn't snag on the edge of the battery.

    • If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

    • If the adhesive breaks off underneath the battery and can't be retrieved, continue with the next step.

    • Repeat the previous pull-tab removal procedure on the second pull-tab.

    • Follow the same procedure as with the previous strip: don't press down on the battery, keep the strip flat and unwrinkled, and pull at a low angle.

    • If the adhesive breaks off underneath the battery and can't be retrieved, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).

    • Wait about one minute for the alcohol solution to weaken the adhesive.

    • Use the flat end of an opening pick or a plastic card to gently lift the battery.

    • Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

  20. Xiaomi Redmi Note 8 Battery Replacement, Remove the battery: 20 단계, 이미지 1/2 Xiaomi Redmi Note 8 Battery Replacement, Remove the battery: 20 단계, 이미지 2/2
    • Remove the battery.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

    • Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard.

    • During reassembly, temporarily reconnect the battery to the motherboard to help align it correctly. Disconnect the battery after it is seated.

결론

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

For optimal performance, calibrate your newly installed battery after completing this guide.

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 device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow these instructions in reverse order. During reassembly apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

Take your e-waste to an R2 or e-Stewards certified recycler.
