I've been having some off and on battery drain problems lately (no user-made recent changes to device - VZW TP2 with WM 6.5). Take this morning for example. Device fully charged at 5:30am. No phone callse, no e-mail (Exchange Push and one POP account that checks every 15 minutes). By 7:30am I was down to 60% charge. That's a 40% drain in 2 hours with almost no usage. I'm confused considering just yesterday things went well with some calls and a good bit of Push e-mail and I only used 50% of the battery in a full 12 hours.
