Use this guide to remove or replace the battery on your Xiaomi Redmi Note 8 Pro.
If your battery is swollen, take appropriate precautions.
For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
You’ll need replacement adhesive to reattach components when reassembling the device.

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.
-
-
-
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 phone 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.
-
-
-
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.
-
Wait about one minute for the alcohol solution to weaken the adhesive.
-
Use the flat end of a spudger to gently lift the battery.

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.

FD> the isopropanol seeped into my screen, shoot.
Me too. The alcohol solution destroyed the screen.
My advise to other users: do not use the alcohol solution and keep carefully cutting and prying until the battery loosens.
