I know that by going to
Settings > About Phone > Battery Use, I can get some idea of the applications that are using up the most of my battery. I see things like "Cell standby", "Phone idle", and "Wi-fi"; is there any way to drill down even further and find out what is really draining my battery? For example, I am fairly certain that GPS usage is included under 'Cell Standby'.
Any help would be appreciated; I have had my phone for only about three months, and the battery goes from 100% to 0% over the course of two-ish days with minimal usage (some browsing, check-ins), and I cannot figure what is draining the battery.
I am mostly interested in ways of diagnosing power usage in a less broad way, but in the interests of finding out what could possibly be draining my battery, here is what my 'battery use' is reporting at the moment:
- 38% - Cell Standby
- 33% - Phone Idle
- 20% - Wi-Fi
- 6% - Display
- 2% - Angry Birds
- 2% - Maps
I have been on battery for 8h 50m, and the charge has gone from 100% to 64%.
