I'm giving the N810 I'm having a chance and am trying out some things with it and so far I must say I'm as in love with this device as one can be without breaking some state-laws..

One thing that I would want to get some input on is the battery life/consumption I'm experiencing.

Ex: Last night I had the battery at about 90% when I went to sleep.
Seven hour later, when I woke up, it was at 5% and when using it for 10-15 mins I get a battery/charge warning and the device shut down 10 secs later.

What I had running: Gmail notifier (set to check every 30 mins), Weather forecast applet, RSS reader applet, Mauku was running (icon shown in the left hand side), Skype was also running (icon in left side), I had an active WiFi connection but no BlueTooth - I also noticed that the GPS icon was showing in the top and seemed active.

So, reading some threads here on the forums it seems like this might all be explained by the apps I had running (or am I wrong?).

I really like having things like gmail notifier, mauku, rss reader, weather reader active - but do I have to close them all every time I go to sleep/don't intend to use the tablet for some time?

Is there a mode that "disables them" but keeps them on my tablet and hence preserves my battery (but allows for the alarm clock to still work)?

I guess the question is,
a) Does my apps listed above fully explain the battery drain, and
b) how do you guys 'turn the device off' in the evening and/or when you don't intend to use it for a couple of hours?
