Take care not to crease or bend the battery—it can leak dangerous chemicals and/or catch fire.

With one hand, fold the two upper and lower tabs out of the way of the battery and firmly hold down the frame.

Pull up on the blue battery pull tab with strong, steady force until the battery is separated from its adhesive in the phone.

If the battery doesn't budge, apply a few drops of isopropyl alcohol (90% or greater) beneath the battery, wait a few minutes, and try again.
