Battery repair failed... why?
I followed the instructions to replace the battery on my iPhone 4 Verizon. The phone wakes up when plugged into the wall but doesn't hold a charge.
I've repeated the process several times trying to get a different result but no luck. After the first time I wore plastic gloves and wiped down the inside with hydrogen peroxide to make sure there were no finger oils getting in the way.
I successfully changed the battery on an iPhone 4S in the same go.
What could be the problem?
