***EDIT*** my battery life is still acceptable. I'm still trying to pinpoint the cause of a drain bug that seldom gets triggered, and drains my battery within 10 hours or so. But most of the time I get decent usage. about 15-18 hours always connected, listening to 5-6 hours of music, 30-45 minutes of phone calls, some internet/messaging(maybe 1-2 hours) and all of this usually while connected to wifi internet, and sometimes to 2G.. 2G phone is almost always on except when I'm in areas with very poor reception, I just switch the cellular radio off and only use wifi.
