I don't know if this is at all the same issue but I've noticed that in the mornings when my alarm goes off, if I've hit the snooze a bunch of times, the battery reading will be under 100% when I finally wake up despite the fact that it's still plugged in to the charger. So I'll unplug it, then plug it back in and the weird thing is that as soon as it's plugged in again, it will suddenly show it's 100% charged even though it's not.
Anyone else having that happen? It kind of sucks not having that full charge when I unplug it in the moring (unless I want to plug it back in again and let it charge back up). I didn't notice that happening the first 5 or 6 days I had the phone... It's just been the last few days.
