The complete cycle method is generally used to calibrate the charging circuitry in multicell laptop batteries, as the batteries in mobile devices like ours generally only have a single cell it's actually pointless (and marginally harmfu) to do complete discharge cycles (as there's nothing to calibrate).
personally i'm a heavy user of this N900. getting a spare battery. trying to find a desktop battery charger.

Ok another test thats a little more controlled. I fully charged my N900 last night before I went to sleep (~4am, most likely a bit later). Got up a little while ago (we'll say 10:30am and make it an even, generous 6.5hrs).
Stuff running/settings (display was off)
- I left it with the alarms/clock app open.
- Facebook widget
- Weather widget
- WiFi
- Email checking every 15minutes
Battery was around %50 when I woke up, maybe a tad less.
That's kind of terrible, seems surprising even to me, having used the device the past week. I'm guessing it's either the facebook widget or weather widget that caused most of the drain. The apps released before the N900 was even out couldn't have been tested that well. For example, I had performance issues early on that seemed to be corrected by removing the AP News widget.

Ah sorry, I'm on AT&T at the moment. Using ForecaWeather, looking in the settings there doesn't seem to be anything about GPS or automatically reporting your location. I had to switch it manually from London to New York. Set to check weather every hour.

wow, such a heavy battery drain and you're not even on 3G! Had you installed any apps other than the one that come with the phone? Hopefully its a runaway app and not because the n900 cannot go for more than 12hrs with the most minimal use

I must agree... the battery life for the N900 is terrible. My N95 ( which has 2+ years old batter) still produces more energy than the battery of the N900. Don't get me wrong, I like the phone but the battery life is terrible... Hence, I ordered for two additional batteries on ebay.

I checked the calendar a couple of times, sent an SMS, changed a number of settings, shot a few seconds of video and took about 6 photos. The GPRS signal is lousy - the phone has to keep connecting and disconnecting. In fact, even the basic cell phone connection drops repeatedly.

Battery was around %50 when I woke up, maybe a tad less.
Then I returned home, so it switched to wifi. I didn't have time to do much before going out again (back to GPRS) and then came home about an hour ago. Since then I've adjusted a few more settings, checked things on the desktop and done a bit of playing around. In total it's been unplugged for nearly 13 hours, 9 of those on GPRS, 4 on wifi. The battery is showing about 2/3 full.
One question: do you have the sceen set to full brightness? People who have it set to 4/5 seem to be reporting better battery life. (Though I can't see that mattering while you're asleep!)

If the answer is maybe
could it be dependent on the size of inboxes and/or IMAP vs. POP? There are reports that the email app is very slow on large inboxes - implying it's a CPU hog at processing them. That shouldn't affect fetching a few new mails but you never know, if it's doing something silly to compare remote and local inboxes. Just a thought.We could with a tool that measures the cumulative system resources spent on different apps - CPU time, network activity etc. "time" does it for one process, but not cumulatively over many instances of the same process.
