Ok you lost me... Diablo? Chinook?! What are those?? I really need to learn more about this stuff...

12 hours?!!! How on earth did you get that?! that's like 4 times what I get!

I used mine this morning, for a bit of light typing on the way to Physio, just for 30 minutes in the car, and it has nearly halved the battery power... It was on charge all night! Started off by saying 12 days idle and 8 hours in use, now it's saying 8 days idle and 5 hours in use.... But I know it's lying and won't last anywhere near that

What your looking for is any process listed as using non-zero cpu, while all your seeing is the "desktop".

then write the names of the processes here.

Btw, chinook is maemo4.0, also known as os2008, its the version that the N810 shipped with originally.

Diablo is 4.5 or there about, its basically a updated chinook, with the really big thing being over the air updates of the os itself (until then, a system update meant a reflash of the device).

Thanks^^ That's a great explanation! I actually understood it Maybe I'm getting the hang of this

I think I must be running Diablo in that case, if that makes any difference to any of this.

Ok processes.... I have 62 processes that are at 0%

The only ones that are doing anything are:

Hildon-desktop at 10%
Xomap at 4%
and Browserd at 1%

I can't see that any of the others are using the CPU.

browserd? unless your using the web browser at the time, that process should be doing nothing.

on that note, are there more then one browserd? it fires up a second one when the browser is actually in use.

Yes, there are two of them. Now they are both showing 0%

I haven't used the web browser all day and WiFi is still off.

Also, I have like 14 of hald-addon-omap-gpio

Is that normal??

I believe maemo-launcher is just the generic name for process launching (sadly it doesn't tell us much). If you open a bunch of programs at once you can see several maemo-launchers showing up and then being replaced with actual program names.

I've yet to figure out what the one maemo-launcher that stays on my system eating up 12-20% of my memory usage is though. It shows up there even when I boot my tablet freshly.

maemo-launcher is a system for speeding up the launch of gtk based programs, iirc.

basically it preloads the gtk libs, so that when a program launches they get a copy handed over or something like that (the unix way of dealing with libs can be quite memory effective if a lot of apps share libs).

You could try installing the HomeCPUSpeed applet. It could be that your CPU is stuck at a high speed. If so, that could be a hardware error since the OS has the ability to manage the CPU speed.
Ever since Chinook (the OS version before the latest one which is Diablo--as you know ), the OS has the ability to vary the CPU speed according to need. There are apps that will allow you to manually alter the CPU speed--one of these is Liqbase.

I used to have a Tapwave Zodiac, but the screen died. When I tried to fix it, the battery fell out and, thereafter, the battery always ran out much, much faster than before. I suspect that the wire connecting the battery to the board had been partially broken. You could have a bad battery connection in your Nokia as well.
I'm in China where there are small cell phone repair shops all over. These guys are supposed to be wizards (according to one of my friends)--they download schematics off the internet and can fix almost any gadget. If all else fails, perhaps you could find a cell phone repair place near you (obviously, not in China) that could check the circuits in your device.

I'm sorry to bring you potential bad news ... but ...

As you completely returned your unit in a virgin state with the latest release of Maemo, your problem shouldn't be software related.

So, maybe your battery is faulty. But you told us you changed it ... by a new one ...

So, now, let's face 2 possibilities :

- either your power suply is damaged and doesn't provide enough power to properly charge the battery (maybe it's just the wire that is somewhat damaged ?)

- or your unit charging circuitry / battery management circuits are damaged

Maybe you could borrow a friend's Nokia charger and try it ?

I boot my N800 from SD and run my wifi 24/7 at full power either at home or at work. I use only one battery and charge it every night. I can get 3 - 4+ hours of surfing, 6 hrs of listening to XM Satellite radio online, and up to 36 hours in sleep mode while the web browser and other apps are still active (although it rarely goes 36 hours without being used).

About 8 months ago I went through a period of the battery draining overnight with nothing running. I couldn't find any reason for this happening and ended up reflashing and reinstalling all my apps. That fixed it and it hasn't happened since.
