I can go 48 hours on the extended battery and I'm not using SetCPU and I typically leave the screen on auto brightness (though I guess I occasionally turn it down).
Yesterday's usage:
Unplugged the phone around 7:30am. Read emails for about 20 minutes in the morning, checked the weather. Listened to some music on my bluetooth headphones on the way to work, maybe 30 minutes. Started up Appbrain on the phone and downloaded/installed the apps over 3G. At lunch, I listened to more music on the way home, browsed the internet for maybe another 30 minutes while I ate, and listened to music on the way back (all bluetooth).
Showed a few coworkers some of my apps, so another 20 minutes or so with the screen on. Occasional email/text throughout the rest of the day.
At home, I sporadically pick up the phone and browse the internet/read emails/send texts. Easily a solid hour+ of browsing. Played a couple games and downloaded a couple more apps.
When I went to bed and plugged the phone in, around 11pm, my battery was at 50%. Probably a total of two+ solid hours of browsing, an hour of emails, 20 min. texting, 30 min. games, an 1.5 hrs. Bluetooth streaming music and maybe 15 min. or so of phone calls. Plus a little misc. fiddling.
More information about my phone:
- The only radio I toggle on and off is Wifi. Everything else stays on all the time. Wifi goes on when I get home.
- Widgets that update themselves are: a calendar widget, a Google Tasks widget, a sports score widget and a weather widget. All widgets with configurable timers are set to update in 30 minute intervals.
- I have ATK installed but only to let me manually kill processes, it has no auto killing intervals set.
- I am running Launcher Pro Plus. Before I installed LPP, I cleared off my entire Blur desktop - there is nothing on it.
- I am rooted and have removed most of the common bloatware - nothing crazy, just the things like CityID, Amazon apps, Blockbuster, etc.
Hope that information helps someone.
