Just found this floating around the intrawebs:
I would like to create a a definitive guide (best Practices) to get the maximum amount of battery out of the Sensation. Coming from a LG G2x I'm finding this battery is actually equal or worse and since rooting and removing bloatware currenty seems impossible, then customizing this phone has to be within the realm of stock apps and settings..
Using Battery monitor widget, I'm typically getting -200 ~ -300 mAh usage whenever the phone is being used, it will drop down to -30 mAh at its lowest in idle, but no where like the G2x of 5-10 mAh or -2mAh for Vibrant (in idle)..
My goal is to have this phone last 24-36 hours regularly (if possible) ... Right now I'm getting 12-18 hours, with moderate use.. 20 ~30 minutes calls..
Here are the steps I've tried to improve life, in order or decreasing effect.
General Tips/Steps to improve
Turn off All Syncing (use power widget to toggle as needed)
Check Settings >> Accounts & Sync >> [disable auto sync]
Set Screen timeout to 15sec
Set brightness to < 15%
Check Settings >> Power >> Turn on most or all the power saving features in this menu.
Remove (or reduce) number of widgets that need to poll data (includes clock/weather, stocks, social feeds, etc)
Turn off Bluetooth, GPS (when not needed, again use Power widget to toggle)
Enable Wifi calling (yes wifi calling saves battery especially in low 3/4G signal areas)
Use camera sparingly (by far biggest battery hog)
Useful apps or widgets
General apps / widgets and tips to have
Add Power widget to home page (for quick toggling)
Install Battery monitor widget for charting battery usage.
Juicedefender or Green Power from appstore and let them help manage power
