Yes, I've been having exactly the same problem lately. Like you, I am not using modest and I don't have any music or videos on the machine. I also see nothing via top and have disabled metalayer-crawler.

I also keep wifi and bluetooth off accept when I am using the browser.

This is driving me crazy.

Are you using a memory card at all? If so try it without the card, and if that fixes the problem try other brands of card. (I will be avoiding A-data for at least the foreseeable future)

Yes, I use a 16 GB Markvision Class 6 card. It would me more practical for me to turn the device off than to remove the card, though.

What is really strange is the fact that this problem is intermittent (this would mean it is not the card?). Most days everything works just fine, and suddenly another day the battery gets exhausted in a few hours of standby.

Perhaps the battery indicator is inaccurate?

Thanks for the info,
L.

Have you tried to see what processes are running when the battery drain happens? May be one of them uses the CPU excessively and thus results in a heavy battery consumption...

Yes, this is what I suspect also. I looked several times at 'top' output when I think battery is being drained, but I found nothing.

Thanks,

I had a problem with an N800. The internal charger was slowly going bad. Sometimes it charged sometimes it did not. It finally stopped charging complety. I use a desk charger now to charge my battery.

I removed advanced backlight a few days ago and haven't had a battery problem since. Can't actually say that was the answer since my battery problems have always been intermittent, but so far so good.

The only problem I had like this, was like davidgro said, with a 4 GB A-data sd card sucking too much power.

There is a cmd line tool, battery-status you can install that will log battery level at regular intervals. It might help you determine if the battery drains at a regular rate or all of a sudden.

I use advanced backlight on my n800 all the time, and I have had no battery problems with it. You don't have it set to allow zero backlight?

hey guys,


i wanted to jump in here to see if anyone might have suggestions for me as well (didnt wana start a new thread) but exactly how long of a charge do you guys get on a daily basis, i see that if i fully charge it and use it a bit then place it in flight mode with the screen off, it will a about two days. and with wifi on it may last a day in standby mode, but if i'm on it intermittently all day using internet radio and checking my e-mail, while im'ing it last about 2-3 hrs, is that any reason to worry or get an extended battery... also is it possible to over charge the tablet, like if i forget and leave it plugged while i'm at work or the gym..

Thanks,

My battery lasts about 5 hours of intermittant use. I keep another battery in an external charger which charges a dead battery in about 5 hours. Therefore, by the time my N800 goes dead my backup batterynhas a full charge.
