I cannot play video for 2.5 hours on my almost 2 years old N810. I can hardly read an ebook for this long. In addition I have dual boot, including 30s delay. During this delay screen is on maximum brightness, and I don't know which power saving features are enabled, so without this delay, a few more reboots might be possible. > I have posted my findings with one spare N810 to that thread.

In similar tests on a new N800 I never even managed two weeks (in offline mode). 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. -- Matan. _______________________________________________ maemo-users mailing list maemo-users@xxxxxxxxx https://lists.maemo.org/mailman/listinfo/maemo-users
