My existing battery was acting very weird. It would sporadically but off the phone anywhere from 30% to 8% - then tell me it needed to be charged with the red, empty battery sign, when I tried to power it up. If I waited about 5 – 10 minutes, I would be able to power it back on and the battery percentage would be about the same. If I tried to do anything, it would power itself off.
When I would then plug up the phone to my charger, it would take about 20 minutes for the phone to power itself back on. One interesting point is that the phone would always gracefully shut itself off – it would never just cut off.
The repair went good. I think it took about 10, devoted minutes. The hardest part was getting the top cover off. I expected that though. Also, another tricky part was taking out the old battery because apple uses adhesive to stick it in there.
I would offer to take your time, be patient. Keep tugging on the suction cup on the top screen until you get some space between the body and the top. Don’t force anything!
When you are getting the old battery out of the body of the phone, try not to pry it against anything that you might damage. I found myself prying it up, resting the pry tool against other circuits and boards. That wasn’t smart. I found other area’s that I could work on prying it up without damaging anything. Another bit of advice in this stage is to be patient and keep the same amount of pressure going around the battery. Think of it as you might be chipping away at mortar around a brick. Little chips all the way around until it’s finally loose!
Lastly, I found that when you are putting the screen back on, the top portion of the screen should go in first, at a 45 degree angle, then the rest of the screen laid down towards the bottom.
