i know why battery life sucks so much!

I honestly noticed my biggest hit to my battery when I was using juicy's rom. I don't think it was the roms fault, but since it didn't have the task manager, I couldnt really see what the memory usage was as easily and I didn't have quick access to my kill all apps. now I have had my phone off the charger for 7 hours and I am at 90%(sprint stock radio and rom) and I have played over an hour of teeter today. I honestly think its the same old memory management issue as with the touch and the mogul, just the apps thrown on it are beefier (tf3d for example) and therefore killing the battery faster if we are not careful to kill them.

Here is my estimated breakdown of battery drain per hour, based upon my compilation of the many reports in this thread and my own personal observation over the last month.

At idle, Phone On, Data Inactive, BT Off, Wifi Off
Backlight Off - 13Ma / hr
Backlight On, lowest level - 57Ma / hr (add 9Ma / hr for each level of brightness)

Turn BT On - additional 59 Ma / hr. Add to above

Active Data Connection (transmitting) - Additional ~362Ma / hr This is hard to pin down exactly

Active Phone Call - ~268 Ma / hr (Probably will vary with signal strength)


golfman32, based upon what you reported, here is my calculation of your battery drain in 8 hours.

Phone On: ~160Ma (160/1340=11.95% battery drain)
Add BT On: ~472Ma (472/1340=35.22% battery drain
Add 1.5 hours of Active (transmitting) Data: ~543Ma (543/1340=40.52% battery drain

Total: 1,175Ma (1175/1340=87.69% battery drain in 8 hours.

Your report of 15% to 20% remaining sounds about right. BT on is expensive and so is active data.

Unlike many who have reported, I find NO measurable battery drain if the GPS locator is on, but not actively seeking satellites. I always have the GPS locator on. The effect that signal strength has on battery drain is the big unknown. Many have reported that poor signal strength has a big impact. I did my monitoring with the Airave, so these estimates are under optimal conditions.

THanks for this one,
I have the Touch Pro and have been experiencing the crappy battery issue. did the registry "hacks" for turning on the power management and added the battery value of 0x4e20. One thing I also noticed was that had abou 5 apps rnning in the background.
So, today isthe next test. I make sure all the apps are shut down and started with a full charge this morning. I've been on the phone for about 45 minutes and did about 5 minutes of web browsing. The battery indicator is two bars down.
We'll see how it is at the end of the day...
