Replaced my iPhone 5 battery and it went perfectly. Took about 20-25 minutes. As others have mentioned I did not take the entire screen off. I worked carefully supporting the screen and the bottom of the phone in one hand and worked with the other. I figured only having to unscrew two screws and taking out a battery would keep the connection problems to a minimum. Battery took a little time, but slow and steady coaxed it out. Went back together in a snap. Turned it on and started up without issue. Full charge lasted me nearly three days. Much better than the two hours I was getting. Could not be more pleased with outcome.
