The thread goes on. My battery eye graph is as random and inconsistent as others here.

People have said no other device can do IM, Web browsing and Music for this long - but yes they can. Nokia's N97 served me very well in battery life. I often used IM for 2 hours in the morning, and then email and web browsing through the whole day. By midnight I would have usually have about 50% battery left.

With the N900 - one hour of IM would take about 30/40% battery life. That is simply painful. Especially as I have 15 more hours left in the day where il need my phone. Dont always have USB plug in available.
