20 - 30 minutos
my cellphone battery couldn't keep up an hour, even without talking or using applications ... i have decide to give fixit a try!
smoothly, i have to be careful since lots of part were very small and if breaking any connector would lead of damaging the phone mother board. Definetly need to take my time through each step.
My only advice, look up the video on youtube, do a quick search on what you wanna do and you will find people showing how it is done step by step, in video. it is way better then text explanation. i find the video quicker then following the manual on fixit.com. I did use both when i am not sure what to do.
