Hi. My Nokia N800 seems to have a real bad battery drain and I can't figure out why. It drains real fast when using wifi. This I can kind of understand, so I have tried putting the N800 in offline mode and locking the keys and screen. Even after doing that, if I turn the N800 back on after a few hours, It show a very depleated battery, at best, and sometimes it just will not turn back on unless I charge it up again. I have never had any device come this close to real bad battery drain, and that includes the Nokia N95 phone and a apple ipod touch.

Does anyone have the same type of battery problems or any possible solutions for this?
Please let me know,
Thanks.
