Dunno bout you guys but for me, normally (everyday) I'm using the phone for...
1. 3G and HSDPA connection which has 3 email accounts (the main reason why I bought a WM phone; if not I've already bought a Sony Ericsson

)
- Outlook Exchange - checking interval of 15 mins (8.45am to 6.15pm) and 30 mins for the rest of the day
- Gmail - checking interval of 30 mins
- Yahoo - checking interval of 30 mins
* data connection will disconnect if idle for 45 seconds
2. SMS (regular SMSing, not too much and not too low)
3. Calls (maybe accumulated average of 30 mins per day)
So, having only 24 hours of battery life seems kinda sucky (when I was on DXHK3). But now on DXIA2, I think can reach 2 days (we'll see tomorrow

). So, the improvement is almost +100%
