I think that is a general "weakness" in all phones. No phones are able to stay on with wi-fi activated for more than a few hours. Don't act all surprised - It's always been that way.
I'm sure you won't notice any big difference in battery life before you buy another phone. Even if you use wifi and charge it at the same time. The engineers behind the phone(s) are surely smarter than making a mistake like that.
If you charge your phone with a PC with ActiveSync installed you don't need wi-fi because it can use the AS connection.
I really do dislike it when my post is misread and the mis-read is then answered with some very silly comments.
1) I've tried 2 new batteries - same result, despite first charging them both slowly overnight before turning the device on. Yes, I've used the wall charger with Sony Ericsson stamped all over it ... that is to forestall other silly comments.
2) I was pointing out that the battery overheats when using wifi while connected to the wall charger -
every time. The Polaris with a Li-ion battery now 15 months old does
not - it just works all day. So the situation is not the same for all PDA's, OK ?
3) using wifi to transfer maps to and from my office LAN (ie. more than one PC), edit, rerun the geological modeller, test the maps in the PDA programs, edit them there and re-transfer and so on is extremely inefficient using AS rather than wifi. And I tend to work for 9-10 hours at a time, not a few hours to listen to trivia. Again, the Li-ion battery of the Polaris shows no such overheating symptoms, but Li-poly batteries do
4) the same problem applies to using GPS. You cannot run the battery with GPS on for more than 3-4 hours without loss of power. When I field-map, I'm using it constantly for up to 12 hours, so it has to stay on car charging. The SE battery heats alarmingly within an hour or so, the Polaris
never does. And yes, I'm using Sony Ericsson car chargers ...
5) I'm not suggesting that Sony Ericsson engineers were stupid - instead SE cut manufacturing costs with a battery that would suit the Generation Y trivia crowd ... heaven knows there are huge numbers of them. The X1 is not suitable for the heavy use I have with its' current battery configuration
