Battery management

[Guest thatake]

Heya, I recently upgraded my BJII OS to 6.1 and right off the bat I noticed it drains battery quicker, about 1/3 quicker than when it was on 6.0. I always have/had auto 3G, no blue tooth, backlight off, screen turns off in 10 sec - I set everything back to what it was. It used to last about 4 days if I didn't use it much, 2 full days with occsional use with no calls. Is there any other setting that I can look into to save the battery duration with a light use? Or 6.1 just requires more juice?

Couple things I've looked at that could help, but they're fairly serious tweaks. One is running TornadoPowerControl. It's an overclocking utility, but it lets you run underclocked until the processor demand is enough to switch to overclocking. I used it so I could watch videos with bluetooth headphones. Didn't really measure to see if battery life was longer with it, but it should be for light use, in theory at least. If you're interested, I can post a how-to for TPC and the BJII.

Another possibility is keeping Activesync from running in the background so often. This way lets you choose to run Activesync only when you pair with your PC. See XDA developers. I tried this, but haven't worked out all the bugs yet. This technique makes you set up a dummy exchange sync profile so you can alter the Activesync settings. At the end, you delete the dummy account. After I did that, I couldn't sync successfully. Maybe keeping the dummy account (it doesn't do anything other than let you change settings) would be the key.

Thanks dsilver, this is very interesting. When I upgraded to 6.1, I did notice Active Synch was requiring an exchange server - I'm on a goodlink provided by my company, so this wasn't something I was going to do to mess up my email. But faking things out all the way may just be the right medicine. I'll try it out this weekend.
