A few months ago, a friend gave me an old phone - it had been a "works" phone and had been relegated to the cupboard when a new one was provided. The phone is a Samsung Galaxy S (the original gt-i9000). It's been flashed and is currently running CyanogenMod 10.
GPS is turned off, as are bluetooth and wifi - I don't use that stuff, this is just a phone with which I can take pics if needed and whichi I can (and do) use as a music player for the commute (and on which I play angry birds when I have some "alone time" )
I charged the phone overnight, and unplugged it just before 7.30 this morning. SO far today, I've sent one text and received a reply. It's now 10.30 and the battery is down to 80% already.
20% battery use in 3 hours. really?b Battery use shows 66% used by Android OS, then the next biggest ones are 8% on facebook and hotmail - these things are installed but very rarely used and are set, where possible, to manual updates only
Should I be turning the phone off overnight to force services to shutdown and clear caches? Is there a way of figuring out just why Android OS needs to use so much battery? Is it just a shagged battery from being used so much?
