I don't have the typical battery drain issues many other users have. I am wondering if anyone has had this problem. I'll often plug my phone in and charge it overnight. In the morning, I'll pick it up off my night stand, notice the battery life at 100%, but within a few minutes of using the phone while still plugged in, the battery life starts to go down to as low as 94%. The only way to reverse this is to unplug the charger, then plug it in again. Then in about 10 minutes, the battery life will read 100% again. That shouldn't happen. I never experienced this problem with the iPhone 4. Would the soon-to-be-released iOS 5.01 fix this, too? Thanks.
