My LG Intuition doesn't seem to fully charge part of the time. Some days it does, and some days it doesn't. I had it plugged up from 10 p.m. last night until 7 a.m. this morning and it still wasn't fully charged. Is anyone else having this problem? I don't think the problem is the charger or the USB cable. I don't appear to have any apps that are misbehaving either.
