I just wanted to share an interesting test I recently performed. Due to constant frustration with my battery life, I decided to remove all my apps and see if things improved.
I ended up removing every app (I had around 100), except the following two:
Google Voice ( I use it for text messages )
Battery Left Widget ( I used it to track estimated battery life )
Before doing any changes, Battery Left Widget was showing about 9 hours and typically at the end of a work day the phone was almost dead.
Today, with just those two applications, the situation is completely different. Here is where I stand right now:
Battery Remaining : 30% ( per the Android OS )
14h 17m 19s on battery
Cell standby : 42%
Phone idle : 40%
Wi-Fi: 8%
Android OS: 7%
Display: 3%
Android System: 2%
Maps: 2%
The Battery Left Widget is saying about 22 hours of full battery life, but you need to run it on a few full charge/discharge cycles to get a better estimate.
In the past, when the phone would die in around 9 hours with minimal usage the percentages of usage seemed similar to what I got after removing the apps... Cell standby and phone idle near the top, and very minimal use by my applications. So nothing on the list clearly jumps out as a reason for the difference.
This was done on a stock, non-rooted, D3.
If anyone is interested in seeing if they get similar results, request you post to this thread stating the following:
1) Battery life before removing all apps
2) Battery life after removing all apps
3) Estimated full battery life based on "Battery Left Widget"
I can tell you, getting used to no apps isn't fun but it is an interesting test. I figure "no apps" or "almost no apps" is a great way to test battery life against other users for comparison.
