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.

Your readings may be different because you are getting them from NuePower, which reports 100mA higher.

Here is my response to a similar question:
I have NuePower installed for the 1% battery display. The readings that I have reported are from Homescreen Plus, which is a plugin that I use in conjunction with SecondToday. Homescreen Plus reports -100Ma than NuePower. Both Homescreen Plus and SecondToday are by the same vendor. If you are interested, the link to the site is http://www.chi-tai.info/cs_wm_tools_im_cs.htm. I find this combination of the SecondToday and Homescreen Plus convenient and Homescreen reports CPU usage, battery status, and discharge rate, among other things, on one easily accessible screen.

Both tg1.0 and the7thson appear to be using SystemInfo. They give the same readings as Homescreen Plus (-100Ma less than NuePower). tg1.0 posted a zip file on page 5 of this thread.

mabmarc appears to be using NuePower. It reports 100Ma higher than the others mentioned, probably due to its polling method or screen redraw? There is a link to NuePower on one of the threads, maybe in this one.


You should consider using one of the tools above before comparing your readings. All readings were at the lowest backlight level. Once you have standardized your readings, you may find them consistent with the others that have reported. If not, at least you can begin to isolate the problem.

Use the link to the Updated Readings above to compare. Other information found in this thread is based upon different backlighting, different tools, etc. As the readings became more clearly understood, they have been standarized and are more reliable. For example, I did report a reading of between 75mA to 84mA somewhere in the thread, but that was with higher backlight settings. The standardized reading, at the lowest backlight is 57mA. This is identical to the others that have reported.

Actually, I expect 103 hours in standby (1340mA/13mA). Over several days of observation, I am sure that my device will get that, although I have recharged after 49 hours in order to conduct other tests.

My signal strength from Voice Command is 60%. Neat trick. Never tried that before. I am not sure what it means though. The phone itself, when connected to the Airave, reports the signal strength of the EVDO connection in the Status Bar, even though the phone connects a call through the Airave. I am not sure what signal strength the young lady in Voice Command is reporting.
