I get about a day (18 hours), but I have Fring on at all times, I think that's fair usage.
All programs off, flight mode not on, wifi off, 3G on, BT off, push off:
On, awake: 150 to 68 mA (150 mA for 10 secs, then drops)
Sleep (press power button shortly or wait long): 13 mA
Flight mode on:
On, Awake: 143 mA to 68mA (150 mA for 20 secs, then drops to 90, finally down to 68 after 30 s)
Sleep: 53mA to 15mA
Be sure to give it enough time to let it settle in sleep mode. It continues to use up to 70 mA in sleep mode until about 30 seconds into it.
