Interesting, the battery life and management was the only part where I thought it was really good. I never ever managed to drain it even on long days.

I did not do too much, Browser, GMail, Camera, Music. That's it. It crashed on unlocking quite often. I'd get a black screen and the small rotating logo would appear. After the OS was back again it needed a reboot as no app would start up again in this "recovered" state.
