hmmm. My N800 recently began running the battery dry in only a half day or so; as you mention, it used to go days between charges. This began suddenly with no change in habits or new packages having been installed. Since I really only use the device at home and at work, I ruled out anything to do with the whether or not the APs support WLAN Power Save Mode. As I said, it all worked great until recently. It is frustrating. Even if I charge overnight, I'm sure to hear the N800's plaintive wail for the power adapter just after lunchtime. Could my battery simply be dying? Is there any way to check? thanks Dave
