My iPhone would no longer keep a charge.
The repair was very simple and the directions were adequate. The old battery was a little harder to remove than I expected because of the sticky gum keeping it in place.
I also used a video from a different online area that gave me a little more confidence. The kit and battery price of ifixit was very competitive and worked well. A high quality video of the fix would be better than steps with photos.
Overall I was very happy with ifixit and my iPhone charges like new!
