You know what i make from this thread and other's similar? That there is no single culprit for battery drainage. It sounds like doing anything on this sucks the life out of the battery. True some report miracles with 20+ hours with always online. I dont think MfE is to blame. I dont think IM online is to blame. I dont think Ovi maps is to blame. I dont think MicroB is to blame. Ultimately, they all are to blame. I have disabled every possible function of the phone and discovered it made no difference (lowest brightness, all radio intennas off - except phone function, vibration off, zero multi tasking) and battery drops life like a .... (View The graph) - Internet browsing through the wifi drains the battery AS fast as 3G. - When the phone radio is offline (underground train) the battery stabilises but still falls. What does this tell me? well that no application is sucking the battery excessively. No extra devels app uses the phone radio so this filters this possibility. - Idle. Not really, connected through 3G (check emails etc, but not online on any IM account). But nothing else. Kinda idle i guess. I know, with long testing that 2G is wonderful to the battery life. But who can seriously advise that we use 2G on a daily basis? it's fine for IM chat etc but when you have to open a browser window the pain returns.
