s33 & JorgeFX: see from 20:00 hrs to 7:00 hrs, that's when it was on standby (with WiFi), on my desk, connected to wifi, no widgets with only Nokia Messaging on checking for mails, LED off. The massive drop of 30-35% from 13:00 hrs to 19:00 hrs is when I was driving with sygic on, on a few calls, music playing and some camera stuff, and connected all the time via 2G (no autodisconnect). Remember, I am just talking idle time here, not usage time. Oh and in the night I did wake up couple of time(s) to check I don't have any custom kernel yet. So, that will be the next step.
