Re: i know why battery life sucks so much!

Here's my results from nueBattery also with an Airave:

1) Phone in Airplane Mode (radios off) screen completely dimed = 148mA
2) Display set where I can read it / AP mode = 193mA
3) Radio on, Internet Connection on, BT off = 193mA
4) As per 3) with BT on = 225mA

So if you're getting only 75 - 85mA of draw, WOW. That's like 1340 / 85 = 15.7 hours of standby. Mine is more like 1340 / 193 = 7. Now that sucks! I did just notice that ActiveSync causes about 100mA of draw. Make sure to shut that down! I'm letting ABC TaskManager run to see what the average draw is. I'll post my results.

RESULTS:

Battery was all over everywhere from about 50mA to 400mA. My guess is using 30min timescale was way too big and reflected the polling of the battery. Swithced to 2 min timescale and the average use is just under 100mA with backlight on and about 50mA with the backlight off.
