Ok - this really isn't about usage. I'm getting what I would consider decent battery drain given what I'm doing during the course of the day. And certainly better than I got the first 24-48 hours of having my first iphone. But I've noticed (twice) now (got mine on launch day) that after plugging it in at night (I also turn it off while it charges) - I wake up to 100 percent - but the usage/standby meter doesn't reset and my phone sticks on 100 percent. This doesn't happen often - today is the second time in over a week. Software? Calibration issue? Should I reset the phone now - or wait until it's either fully charged or fully depleted? thoughts? Other than this - my phone operates as it should so I would prefer not to return it if at all possible.
