I recently updated my smartphone to Android 2.3 “Gingerbread”, and very quickly began noticing shorter battery life. See picture below. It was taken after a full day of only the following applications being used:
- Phone call < 5 min
- Browser usage < 15 min
- Idle rest of time
It’s indeed strange that the “Android OS” is taking up the majority of battery resources and/or CPU time. Unfortunately, I can’t run ‘top’ and find out the exact process taking up CPU time, but needless to say this isn’t looking good.
