I am frantic! I've read through most of the battery forums, and several have mentioned an upgrade being the culprit, but I haven't installed an upgrade. The battery life on the HTC 8x has been declining, but I thought it was because I discovered how awesome it is to play Pandora all the time. I just got a Bluetooth speaker too, but only used it one day. Admittedly, I am a heavy user, using text, phone, maps, email, web, music, camera all day long (my work). It's great that I can't get calls (again, my work, my livelihood...) My phone is blackout dead, no red charging bar, no vibration, no nothing. I've had it on charge now for 16 hours, still nothing. Anybody know what I should do?
