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.
