N800 is worse, see Igor's post here http://lists.maemo.org/pipermail/maemo-users/2008-February/009409.html My numbers is from my own measurements I did later. The extra N810 was new at that time. > > The main reason I suggest turning off when the device is not going to be > used for long periods (such as a night sleep) is the non-slim chance > that something might cause break power saving (metalayer-crawler, router > incompatible with power saving, forgetting to disconnect bluetooth, > etc.) and you wake up to see a dead device. Yes, definitely. I was trying to solve this by send SIGSTOP to offending processes (browser in particular) when keyboard and screen is locked and it somehow worked. It is relatively easy to do it as powerlaunch script. With nice UI that would allow to picks up offenders by monitoring CPU usage this could be useful tool for poor man's suspend. Basically by locking screen and keys every process except few critical onces could be stopped and later resumed (SIGSTOP,SIGCONT) when device is unlocked. Would not solve keeping audio open etc. Frantisek _______________________________________________ maemo-users mailing list maemo-users@xxxxxxxxx https://lists.maemo.org/mailman/listinfo/maemo-users
