I've been following this thread with interest, since I tend not to get much battery life if I don't do it that way. I decided to do a little "test" on Sunday, so I turned it on first thing in the morning, and never turned it off all day. When I wasn't using it, I closed all open applications, put it in offline mode, and locked the keys and touchscreen. When I went to bed, the power meter said that it had 3 hours "when in use" and 5 days "when idle". When I got up the next morning, the battery was completely down and the tablet had shut completely off. When I plugged it in, I verified the settings, and they were indeed as I reported above. Something is definitely not right. The price that Nokia is charging for replacement batteries is highway robbery, and prohibitive to have one just for a spare, which is what I normally do with my cellphone. I swap batteries in my phone regularly to keep the batteries fresh and active. Mark ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

Thanks. I seem to get various processes eating immense amounts of time and memory when the tablet gets into wonky states, but I haven't found what *triggers* it yet.

I've reflashed, and installed even less than before (I'm putting things back one at a time and waiting a while, to see when weirdness begins).

I had some problems where the battery connections shook loose inside the battery pack, causing my tablet to reboot unexpectedly and not charge properly etc. So I was looking at the charging process trying to figure out what was wrong, and then out of curiosity using the battery-status script from http://nitapps.com/ and logging the output. I hadn't realized that the AP is part of the power-saving scheme; there is a power-save option on the tablet under advanced/other in the connection manager. If unchecked, battery life drops from 100 hours to 7 hours on my APs (Dlink at home, Proxim at work). I tried setting the WiFi to 10mW but it didn't make much difference. I agree; the backlight should turn off. With the light on, I estimate 9 hours battery life. http://andrew.daviel.org/N810-FAQ.html#battlast -- Andrew Daviel, TRIUMF, Canada ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

Sounds to me like you may be assuming that network connectivity is Bluetooth's only function... What about getting online via wifi while using a Bluetooth keyboard? It would really suck if turning on your keyboard made the internet connection drop and vice-versa. It would be nice, though, if Bluetooth remembered its previous state when a connection is made and restored that state when the connection is terminated. (e.g., Bluetooth is off. Set up an internet connection via cellphone, causing BT to be automatically turned on. When the internet connection is terminated, then BT should automatically turn off unless something else is using it.) -- News aggregation meets world domination.

No: I have both bluetooth and wifi enabled (and autoconnecting to any known access points). My tablet is normally not discoverable over Bluetooth, for security-by-obscurity purposes. The battery life is normal: if I don't use it the whole day, it still shows 100% in the applet. I've heard that there are some wifi accesspoints that don't support power savings properly, and make the tablet use much more power when connected.

They went to great lengths to "protect" the devices from their legitimate owners, while leaving the owner's data completely and utterly exposed. That's one really good reason why (whether they agree or not) Nokia should have made a decent PIM part of the package out of the box, and it's probably the major reason why they didn't; they didn't want to go to any effort to deal with the security side of it. By pronouncing the devices "NOT PDAs" they're attempting to absolve themselves of any responsibility on that front. However, there's no justification for assuming people want to carry around another device, especially when with VoIP it's perfectly legitimate to expect some people to do without a smartphone (or maybe even *any* mobile phone) if they have one of these. Why didn't they just force owners login to their tablet like you do in most Linux distros? If they used the same kind of login process as desktop Linux, users could choose whether to autologin if they don't care about security or require logging in if they do. Between that and the "lock device" feature (which should also have a timeout feature to automatically lock it after a selectable period of inactivity and would work like screensavers that can be set to require a login to exit the screensaver) would go a long way toward satisfying basic security needs.

It seems like it shouldn't come on for the hard keys, either, because it's just as easy for one of them to get pressed in a pocket or bag as it is for the touchscreen. If the owner doesn't know the key combination to unlock the device, they shouldn't lock it in the first place.

What state did you leave it in when you put it in your bag? I normally carry my N800 in a belt pouch and, if I don't "Lock touch screen and keys", the battery will run completely dry (as in I have to hook it up to the charger to get any response at all, and, when I do, it reboots) over the course of several hours, presumably due to the touchscreen being bumped, causing the backlight to trigger. OTOH, once I figured out to lock the screen, I no longer see any appreciable power drain in transport. (Actually, aside from power use, I know that random bumps were registering on the touchscreen due to applications starting up and some of them (such as Maemopad+) showing random "scribbling"... I first started locking the screen to prevent this; the battery not running down was a happy side-effect.) -- News aggregation meets world domination.

Something like that may be going on, though I haven't installed very much. I'm assuming the application would have to be running to make a difference? Yesterday I started the day fully charged, and it spent the day in my shoulder bag, and when I unlocked it near bedtime to read for a little while (not having touched it since I took it off the charger in the morning), the battery was down to 3 days standby, 1 hour active.

Hm... But that still leaves these being a problem. I can probably just be careful about ssh agent and keys, I don't use it *that* much on the N800. My fallback position on the email config would be to be prepared to change the password there on short notice, which is easy enough to do. It's a bit inelegant. Also anything where the browser is keeping the passwords for me would be at risk. I know *so* many people who have had portable electronic devices lost or stolen, I really do think it's a much bigger threat than desktop systems (I do know some people who have had those stolen as well, but not nearly as many).

I ws confused about this when I got mine, and it's very poorly documented. You just leave it and the screen goes away. Really. I bought a leather case for mine, so when I'm done I just close the case and put it into my jacket (inside) pocket. It took me a little while to get to trust it (which is why I consider it badly documented, because it's behaviour contrary to expectation), but it seems to work. What I *do* get (unrelated) is the occasional hang on the wifi side, with the wifi monitor failing to relinquish a network when I move out of range. Normally you get the "ching-chung" noise, but if not, check it, as I have found it hung with the screen shining, which of course runs the battery down in an hour or less. But it's very rare. ///Peter ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

I normally use "Lock touch screen and keys", but perhaps that's not secure enough for you.

Lock, sleep, power-down
I'm apparently confused about the various states I can leave my N800 in. When I hit the power button and select "lock device", I get an unlock dialog on the screen. And it *stays* on the screen, overnight, in my bag, wherever, until I unlock the device. That's unexpected behavior; it uses power (backlighting is on). The only other useful option is to power down the device, which requires a full boot to get it back (slow, I'm told it uses a lot of power). Is there a preference somewhere I've messed with causing this? Or that I could mess with to make this go away? I want some way to set the device into low-power-consumption mode quickly, easily, and securely, and then bring it back quickly, easily, and securely when I need it (entering a lock code is acceptably easy). And I worry about heat issues if I put the N800 in the slip case and the slip case in my shoulder bag and walk around outside during the summer while the device is also running the screen and backlight. -- David Dyer-Bennet, [EMAIL PROTECTED]; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users
