hi, I am writing here beacuse I don't want to start a new thread, but I really getting annoyed. I have a lumia 800 with the .12070 firmwere version, and have all the battery draining options except for wifi and autobrightness turned off, running 2 live tiles, 3 emails (sync set for 1h), and a facebook account, with almost no music, max 20min of calls, 20 sms per day, no games, and a little browsing on internet. My battery lasts me 10 hours on a good day, usually runs on critical after 8hours :/ any suggestions?
