Getting approx 48 hrs with standard use (bit of surfing, email, txt's few calls bit of music on the way into work etc).
Decent 3G coverage at work and wifi at home, phone rarely has to hunt for signal.
Phone was charged last night and is showing 89% remaining - unplugged since ~ 7am thismorning.
Screen usually sits at the lowest brightness which is fine for indoor use.
I found a HUGE difference in battery life switching chargers. Originally used the supplied USB lead via a cheapy charger adapter thingy (how techincal! - it's the ones which allow you to plug in a USB lead and charge your phone)
Now switched to the charger which came with my bluetooth headset and that's helped no end with battery life. A full charge takes MUCH longer (usually ok as its charged overnight) so that maybe something to do with it.
