Use a pair of blunt nose tweezers to peel the black colored end of the left pull tab off the battery.

Grab the pull tab with your tweezers and slowly pull it away from the battery, toward the bottom of the Redmi Note 7.

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

Don't press down on the battery. Hold the Redmi Note 7 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.

A good way to get this done is to pull out the adhesive strip about 3 cm and then roll it up on your tweezers.

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.
