Peel up the black pull tab at the top of the battery, and pull slowly but firmly to separate the battery from the adhesive holding it in place.

The battery separates more easily if you add a few drops of isopropyl alcohol along each side, to soften the adhesive beneath. High concentration (90% or greater) alcohol will not harm your phone's components.

Heating the area behind the battery can also help soften the adhesive, but be very careful not to overheat the battery.

If the pull tab breaks, use a spudger or an old credit card to pry up carefully on the edges of the battery until it comes loose.

Don't deform or puncture the battery—it can catch fire and/or explode if damaged.

Never reinstall a damaged or deformed battery. Replace the battery.
