Follow our iOpener heating instructions or use a hair dryer to heat the adhesive securing your battery to the rear case.
Lay the iOpener flat on the backside of the iPhone to the right of the camera. Smooth it out so that there is good contact between the back of the iPhone and the iOpener.
Let the bag sit on the iPhone for approximately 90 seconds before attempting to remove the battery.
If using a hair dryer or heat gun, heat the back of the iPhone until it's slightly too hot to touch.
