My phone is an HTC Inspire, and it's the most ridiculously fast battery draining phone I've ever seen. I could go the whole day without turning the screen on and I'd still be lucky if I had any juice at all left.

But hands down, the worst culprit, the most pitifully inefficient battery powered device I've ever witnessed is the Sega Nomad.



This thing took six AA batteries and you got an hour of play on a fresh set of batteries, if you were lucky. And no, I'm not exaggerating. It was usually more like 40 minutes.
