15 minutes - 1 heure
My phone 5 battery wouldn't last very long, and I would often find myself with a dead phone by lunchtime.
I thought I had a case of a battery going bad, so I called ifixit to the rescue, and replaced the faulty component. I couldn't see a real difference before and after, so I actually think that the problem is not with the hardware, but with the latest ios...
It was extremely straight forward! The provided tools and the instructions made it a breeze. It took probably 20 minutes, with 15 of that time just looking at the instructions!
Proper diagnostic is the key a of a successful repair!
