I am having an issue with my 3gs that has JUST popped up in the last couple days. I leave it on the charger all night then pull it off in the morning. It USED to always say 100%, as it should since it was on all night but the last couple days it says 99% when I pull it off. If I plug it back in, it immediately goes to 100%, but then as soon as I unplug it, it goes directly back to 99%. What gives? Anyone know what might "fix" this? Thanks!
