Jun 03 11:07:23 <Maxdamantus> This N810 battery seems to be working quite well. The device has been on without charging for around 8 days and the icon seems to show it still at around 75% (can't see an actual number).
Jun 03 11:07:39 <Maxdamantus> Seems fairly low-power overall.
Jun 03 11:07:50 <Maxdamantus> Dunno if it goes into a sleep state.
Jun 03 11:07:50 <KotCzarny> o.O
Jun 03 11:08:06 <KotCzarny> afair my n800 ate through battery in ~7days
Jun 03 11:08:29 <Maxdamantus> It's not connected to wifi or anything.
Jun 03 11:08:57 <KotCzarny> what is the battery voltage?
Jun 03 11:09:47 <Maxdamantus> Wonder how to tell without taking it out.
Jun 03 11:10:05 <Maxdamantus> It doesn't have the same chip as the N900 at least.
Jun 03 11:10:09 <KotCzarny> there was a tool for that i think

Jun 03 11:11:58 <KotCzarny> written by me, so might be awfully inacurate
Jun 03 11:12:03 <KotCzarny> feel free to improve
Jun 03 11:14:25 <KotCzarny> and related post: https://talk.maemo.org/showpost.php?p=153728&postcount=13
Jun 03 11:22:06 <KotCzarny> see the last post of that thread
Jun 03 11:22:50 <KotCzarny> and whole thread has some nice notes
Jun 03 11:23:20 <Maxdamantus> retu-adc #8: 450   batt:  52% [###___]  idle:154.0h idle(w/wifi):57.9h max:2.0h
Jun 03 11:23:39 <Maxdamantus> Is that 450 as in 4.5 V? That doesn't seem right.
Jun 03 11:23:50 <Maxdamantus> No, because -bf is 550.
Jun 03 11:24:10 <KotCzarny> nah
Jun 03 11:24:13 <KotCzarny> its not the voltage
Jun 03 11:24:16 <KotCzarny> just raw values
Jun 03 11:24:27 <KotCzarny> and because retu is undocumented you can only guess
Jun 03 11:25:13 <Maxdamantus> But if it's an ADC connected to the battery, it should universally correspond to a particular voltage.
Jun 03 11:25:27 <KotCzarny> but you dont know what that register reports
Jun 03 11:25:41 <KotCzarny> might be scaled value
Jun 03 11:26:20 <KotCzarny> and as i've mentioned in the post, graphs can shed some light what those values mean
Jun 03 11:26:24 <KotCzarny> see the plots
Jun 03 11:26:52 <Maxdamantus> But presumably it will still return a particular value for a particular voltage, so someone just needs to figure out the corresponding values, which you can do by attaching a multimeter in parallel with the battery, or just providing a controllable constant volage power source.

Jun 03 11:27:35 <KotCzarny> the others are from different runs
Jun 03 11:27:49 <KotCzarny> https://mrrau.eu:20281/n800/kcbatt/batt2gp.png this seems quite long run
Jun 03 11:28:00 <KotCzarny> legend in the middle
Jun 03 11:29:21 <KotCzarny> funny that light sensor reports temperature too
Jun 03 11:30:45 <KotCzarny> you can see that 400 should correspond roughly to 3.6V
Jun 03 11:30:57 <KotCzarny> assuming you kno the li-ion discharge curve
Jun 03 11:31:57 <KotCzarny> maybe even 450
