After nearly 24 hours, with normal usage (couple calls, texts, internet and some apps), wifi on for the whole time and some 3G I've still got 75% left and my wifi signal is muchos better (seeing as it uses the HTC hardware drivers)
42% left after 48hours off charge

Wifi on, calls, texts, web browsing, 3G on when out. Doing farking good I'd say

Christ if I switched wifi, sync and location services off I'd probably have a lot more left!
