I still haven't seen any reports on battery usage during the night leaving the phone "as is", as I always do (GSM on, all data off).

Checking by battery-eye history, when idle my N900 uses about 0.5% per hour, so about 4% of the battery is used during the night.

Probably putting it in offline mode and unloading the WLAN driver would also save a bit. At least for me it's not worth it, prefer to be available at night (e.g. in case of emergency), and the battery lasts for a good 3+ days (OK, I'm not a heavy user..)

@ndi,

Do you have any references regarding that overnight maintenance?

Reinob, please read whole thread, not only last few posts (especially, that this one is short, only few pages...). Overnight off-line/powercycle was compared and published here long time ago.

@Estel,

Must have missed your post, but I have read and followed the thread from the beginning

I also leave it on all night, but i have every thing on (and i do mean everything) i have a drop of about 5% and here we a talking about the 3000mAh battery, so it really looses some %, a normal battery would be closer to 10%, unless you charge up at night (keep charger connected when sleeping) then it chargers for 1-2 hours of the night and then starts to drop.

Ref. i charge when needed, really no pattern, i never charge doing sleep, and sometimes when im in a hurry and can see that it's low on power i charge it for 10-15minuts, but this still gives me 625mA (half of a normal battery)
For more info on my charging look to post #2 in my battery thread

Reinob, if that is the case - sorry about that. Maybe we're all getting little too sensitive about thread reading, but don't worry - i also read every post in thread that i write to, and also been ''accused'' of not doing so same day, except that from little different cause.

Sorry for this little off-topic, but i think that keeping good atmosphere was worth posting that - as a reminder, also for myself.

@Estel, no worries. I'm a very "passive" user here so I tend to read a lot and post very little.. but of course sometimes a detail or two can escape my attention

sorry for my bad english but at the end what is the result? turn off or offline mode to consume only a bit the battery? :-)

@iscio,

If you turn off the phone during the night the battery goes down by about 1% (due to the shutdown and restart), while leaving the phone idle during the night takes around 4-5%.

So if you don't need to be available during the night, turning the phone off saves some battery.

Not at hand, but you can use Google to check, there is a bug on Bugzilla about Calendar being open in the morning, Nokia said it performs maintenance at 4 am.

Also, if you want you can check alarque.ini for all the scheduled tasks. The list is quite large. Also on this forum you will find tutorials on how to move/disable updating overnight.

As for wiki, not sure if "off eats less than on" deserves its own page.
