Hi, I have a big problem with my nexus one phone. The battery life of my phone is very bad (only 12 hours, with NO (app) USE! (only text messaging!)) I think the problem is that when I check "Battery Use", the "Android OS" is getting 70% (and more, up to 93%!) of my battery use... What can I do? I've seen other topics with this problem, but there always is a special app that's the problem. I've reseted my phone several times, so no new apps installed, and I still have the problem... But sometimes, "Android OS" isn't running in the Battery Use, only the "Android System"... But once Android OS has started, it climbs up to 70-80-90%... Thanks!
