iPhone 3GS Battery

내 문제

My wife's 3GS would turn off unexpectedly even with a green battery icon showing half the power remaining. The battery would get charged up the night before and would last only a few hours before just shutting off.

나의 수리

The iFixit repair kit, video, and instructions were very easy to follow. The kit shipped and arrived quickly. The repair only took 25-30 minutes and the phone is operating much better now.

내 조언

This wasn't listed in the directions, but make sure the phone is off before starting the repair.
