    • 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.

    • Grab the first 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 a spudger 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.

    • Remove the battery.

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

    • Before installing a new battery remove any remaining adhesive, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

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

Conclusion

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.
