Re: N810 (maybe N8x0 too) turns off automagically
 

Best bang for the buck battery for the n810 and n800 are made by Cameron Sino IMO. About $9 each, including shipping, they seem to have exactly the same life as the nokia stock battery.
I have 3 of them, 2 for my n810, one for the n800.

My battery took a heavy hit today. Unplugged for about 2 hours, no open apps and bam low battery froma full charge...

On the contrary, almost all threads about Mugen batteries say they work fine.
I also replaced the original one with a new Mugen one, and it works fine, giving the advertised capacity. The only small problem they have is the design of the battery contacts, which are a bit loose, but it is very easily solvable with a small piece of cardboard in the bottom of the battery to keep it tight against the contacts.

Hmmm... does GPS suck serious power? I left it on w/ navit by accident, in about 20 mins my tablet was dead. Had a girls # on notes not saved... autosave is a lifesaver

I've a Bluetooth GPS receiver with an 1100mAh battery that lasts for many hours so my guess would be the GPS isn't your issue.

Re: N810 (maybe N8x0 too) turns off automagically
 

In our case, yes, the gps sucks serious power. Of course not enough to kill the battery in 20 min, but in about 5 hours.

Mine took 2 bars off and it was dead in 15 mins. Although, the 'not calibrated' part may have had an effect.

Maybe it's just that your battery is getting old. I think that this kind of flakiness is pretty common for an old battery.

Maybe I should try the cardboard approach. I tried putting duct tape over the bottom and it hasn't seemed to be enough to avoid glitches.

This issue has been a major irritant to me. When my N810 is on, it runs great. :) But if I reboot the system (e.g., b/c the desktop freezes), then it restarts for a couple seconds and then shuts off. Similarly, if I power the device down and then turn it on again it restarts for a couple seconds and then abruptly powers off. :mad: In order to boot again, I need to plug it into the power supply, take the battery out, replace it, push it into the connectors as hard as I can, and power on. Once it has successfully powered on, I can replace the battery cover panel. But if I have to start up away from my power cord... forget it. Sounds bizarre, but the behavior is very consistent. I can give a more exhaustively detailed account if that would be helpful. It's possible that there is some interaction with the boot menu as I am dual booting.

I am forced to reboot often since that damned second row of icons from the tray locks open and prevents access to apps in diablo5.

I have a mugen battery for my N810 and one for my N900 and they are working fine.
