[Android Q&A, Help & Troubleshooting] leola:
For quite a while now I've had a battery drain problem on my xperia sola. I've uninstalled most apps, deactivated WiFi, and it's still no good. My phone drops about 30% of battery load over 9.5 hours of standby.

I've looked around other threads without finding a solution yet.

However, I have taken a cue from other threads and installed BetterBatteryStats. Below is the output from last night's standby. I can't really make out anything obvious from it. Can someone help, please?
