<div><br>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.
<br><br>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?<br><br>thanks
