Apply a suction cup to the back of the battery.

Pull up on the suction cup with strong, steady force to begin to separate the battery from the frame.

If this is difficult, apply a few more drops of isopropyl alcohol underneath the battery, let it sit for two minutes, and try again.

Insert the point of an opening pick into the gap created between the battery and frame.

Don't insert the opening pick more than halfway or you risk damaging the fingerprint sensor underneath.

Pull up on the suction cup to remove the battery.

If you used isopropyl alcohol, wait ten minutes before installing the new battery to allow the alcohol to completely evaporate.

When you're reassembling your phone, remove the old adhesive and apply stretch release adhesive strips, double sided adhesive tape, or pre-cut adhesive to secure the new battery.
