Answer to "Replaced iPhone4 battery. Now randomly restarts and battery % broken!"Hey everyone, what I found was that my phone was doing the same things. I took the back off, examined the battery, plugged in the charger and the phone turned on fine. Everytime I tried to put the cover plate on the phone it would shut off. After looking closely, I noticed a tiny nick in the black rubberized insulation on the connector from the battery to where it connects to the phone. I covered it with a tiny piece of electrical tape, closed the phone back up and no problems at all. Yes electrical tape meet iphone. Now for my paperclip trick.
