Happiest day since my first day with my iPhone
20 - 30 minutos
My phone was randomly shutting off even when almost fully charged. The problem was getting worse each passing week, and after researching on several blogs I discovered it was most likely my battery. I also discovered the ifixit site and the positive comments about your company!
It went great! It took about 20-30 minutes to install the battery. I had taken the phone apart before to fix the screen so I sort of knew what some of the guts looked like, but your videos definitely helped. The instructions you provided were right on & helped me finish up quickly.
I recommend putting the screws in small sandwich bags to avoid losing them. Also, watch out for the small round connector- either #6 or #7 on the logic board. I had some trouble trying to snap this one into place.
