I've not used it at all, only turned the screen on a couple of times to check the battery and have everything turned off. How could I have lost 2 thirds battery in that amount of time with just GSM on and everything else turned off, it's ridiculous.
If on Tmobile turning on and off data uses more power than leaving on 24/7 in my experience. I tried it for a few days, and it zapped battery.
