I got a replacement iPhone 4 about 2 months ago when the lock button broke on my original one. A few weeks ago my battery life took a turn for the worst but I chalked it up to the iOS updates and got used to taking my charger everywhere "just in case". Not a big deal, just annoying. Well, last night I went out with some friends and went to go pull my phone out to take some pictures. To my surprise, my phone that had been fully charged and working fine 5 minutes earlier was completely dead. It would not turn on, and trying a hard reset did nothing. Completely ticked me off. I spent $200 on this thing, plus the monthly bill, and I've had 2 phones go bad on me since September? When I got home, I threw it on the charger, not holding my breath and to my amazement it powered on, still showing a fully charged battery and it's been acting fine ever since. However, I'm wondering what may have caused my phone to be a temporary brick? It's not water damaged, never been jailbroken, and is treated better than a newborn baby. Has anyone had this happen? Is it a fluke thing or do I need to march down to the apple store an hour away and get ANOTHER replacement? Thanks in advance!
