My Nexus 7 doesn't see a ton of use, and at times I find it's completely drained power wise. Standby time doesn't seem to be as good as other platforms I've used.

In the past, I've just plugged in it's standard microUSB cable to a powered USB port on a computer, and came back to a charged device. But this wasn't 100%, and sometimes it seemed it wouldn't start charging.

Tonight, it's now just stuck in a loop, where it boots, immediacy powers down when it hits the PIN lock screen, then ends with a few seconds of video distortion and an audible hiss. Anyone seen similar? Is this a defect I need to be seeking warranty service for, or just bad low power handling?
