Have a look at this thread:http://talk.maemo.org/showthread.php?p=1020718 It worked for me. Patrick BINGO, Patrick! Thanks you a hundred thousand times, that was exactly my problem! I already wanted to write about hildon-input-method crashing and consuming about 90-96% of CPU time. Now you were faster than my thoughts ;-) So is it all about broken autocompletion dictionaries? Doh! Here is the solution from your link (for the conveniency of others falling into the same issue): 1) Run xterminal and sudo gainroot 2) cd /home/user/.osso/ 3) mv dictionaries olddics 4) Restart your phone How do they get broken? (I don't expect you to answer this question.) /usr/bin/hildon-input-method is really the worst battery killer I have noticed. I'm watching my battery using BatteryGraph continuously. Now I'm going to bed to move my broken dictionaries out of the way ;-) Maybe we should raise a bug: 1. The dictionaries shouldn't get broken by autocompletion software itself. 2. If the dictionaries get broken somehow, the hildon-input-method program should not crash or behave in such a buggy way that it consumes all available CPU time. Should I raise the bug or is anyone here to take the initiative? Could you recommend me where to open it? Should this bug's fix be implemented by the CSSU team? Many thanks for you all, guys!

The reviewer stated that his device lasts 3 days on battery when only sometimes calling or writing SMS. This is what I hardly can believe because my N900 lasts only 3, max. 6 hours on battery and then the battery gets discharged. Was the reviewer kidding or is something wrong with my mobile computer? Mine, whith it's quite old battery, can probably last 2 days with this kind of usage (but browsing the web on wifi empty the batterie on 3/4 hours). I'd say you have a program installed that ruins the battery life. ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users Thank you for sharing your experience, Rixed! I am connected all the time to WiFi at home. But even outdoors when not connected, my battery discharges in a couple of hours.

I have recently bought a new battery and the effect is minimal. My device was in repair service already and they changed the motherboard. It helped a bit but I never made it to that 3 days on battery. Any ideas? :-) The biggest leap in saving enery is to use smart-reflex. Thus for you have to install kernel-power 50. Please read all instructions in the wiki carefully before doing so. Installing latest CSSU is recommended too. CU Michael Thank you, Michael! Now I don't exactly know what smart-reflex is for now. I surely can search for it but if you could explain it also for the others, I'd be happy :-) OK, I'm not sure if I have the kernel-power installed for now. I'll definitely install it. Last time the installation ran without problems. CSSU. This is still a mystery for me. It's a sure choice then. I notice I am a bit noob :-D Pavel ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

But it isn't everything. Even when not connected (while I'm outdoors), the battery lives for hours, never days. I'll try to investigate the battery killer ;-) Maintaining a TCP/IP connection drains the battery; so things like IM accounts are the antithesis of long battery life. Some protocols are also thirstier than others. It's a shame, because one of the advantages of Maemo 5 is its design to be always connected. Unfortunately, that isn't conducive to multi-day battery life. Some of the other power (limited QA, mainstream Linux userland, full multitasking) also makes it very easy for software (including Nokia's) to accidentally drain the battery by not being well written, not using the heartbeat functionality and not stopping doing things when not in the foreground. HTH, Andrew Yes, you are right, Andrew. I should then use a connection stopper application. Thank you for the tips. Still, I suspect that something else drains the battery power because I never did it to a day up and running, even when offline.

My N900 lasts 4 days if I use it only lightly: just a few minutes of wifi connection a day plus some short calls and SMSs. When always connected to 2-3.5G it lats only around 5 hours. If your N900 is not lasting when not always connected make sure you install the CSSU from maemo.org. It fixes alotr of bugs.

No, I'm usually not connected to 3G when outdoors. I use 3G on merely rare occasions because it costs money in contrast to WiFi :-) Actually, I don't have “switch to wlan when available” enabled /but/ cca 98% of all the time I am speaking of I had it enabled. As I connect rarely to GPRS, 2.5G 3G cellular data networks and I am perfectly aware of disconnecting it and switching to WiFi, this is not my issue. Anyways, thanks for the tip :-) Pavel ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

You should try setting the N900 in flight mode (or offline mode, whatever it's called) so you can make certain your's not using wifi nor 3g nor anything. Then see how long your phone lasts. Also, while doing so, open a terminal and run top for a minute or two to check CPU usage by programs. Top itself and Xorg should be on top, with only a few % of CPU. ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users
