Grip the pull tabs, and slide it up until you can feel it contact adhesive underneath.

Lift straight up to pull the battery away from its adhesive.

Work slowly. It's easy to lose your grip and accidentally pull the tab up from under the battery. It can be helpful to use gloves for more grip.

If you're having difficulty separating the adhesive, apply more heat and wait for the adhesive to loosen.

If available, have a friend help hold the phone down while you lift.

If you lose or tear the release strip, or the adhesive is too strong, follow the next step for an alternative method.
