20 - 30 minuten
I was handed a hand me down Iphone 3gs and it was about 3 years old when I got it. It was cool but the battery power was horrendous.I could literally watch the battery drain right in front of me. It started to die at 20% then 30% and so on. It got to the point where I effectivly only had 30% of battery and had to constantly have it at 100% or it wouldnt be worth it.Then I got a job and ordered ifixits replacment.
The repair went a lot better than expected.I did goof because it wasnt connecting to the network at first but I took it apart and readjusted ribbon 7 that was responsible for network configuration.It fixed the problem. I ended up taking 30 minutest but only because there was so much dirt and grim in there.It really was not as bad as I thought it was gonna be at all. Funny thing though, I did not use the ifix it guides at all. I dont know, something about just pictures didnt settle right with me. They are descriptive but I found a better guide on youtube.I think thats something IFixit should really start doing.Picture guides are great but video guides are even better.
Really make sure you put the cables back on to the mother board. if you dont hear that click it probably isnt on right. About a week after getting my battery it wouldnt charge anymore.I used many chargers and nothing. I decided to take it apart and readjust the cable to the battery and it fixed the problem. I had the same problem with the network ribbon. So yeah, make sure its fitted well and to be careful and not gorilla grip that $@$*.
