I am constantly amazed by how different people's opinions of the PW battery life are. I keep the wifi on and my battery lasts a blink. Well, ok, 12 hours. Lots of blinks. But still, not very long.
So people say 'it's the wifi/3g'. But the battery on my KT was endless.
Hence, it is the screen. But some users here seem to not have battery life issues.
I am starting to wonder if my unit is just defective. But I charge it every other day...
