20 - 30 minutos
I could be attempting to take a photo or video and it would shutoff. I sent three texts one morning and it shut off. It wouldn't matter if it was at 90% or 100% If it was plugged in to a power source on the other hand I never had had it shutoff on me.
Repair went well, guide helped tons! The repair took me about 58min. The part that took the longest was getting the screen off, after that it went pretty fast.
Just take your time follow the guide and follow it in reverse to make sure you don't skip any screws or cables.
