20 hours (my N900 is only a few weeks old) checking email 8-20 times a day (primarily by WiFi), 2-6 hours of music, with no widgets on the desktop (only shortcuts), with a black desktop background and all components turned off when not in use. Frequent StockThis use (5 times a day) and infrequent GPS use.
At the end of the day I still have plenty of green bar showing.
On the days in which I use iNES or any other game the battery drops much faster.
My notebook computer only gives me 1.25 hours so I'm very happy with the battery life of the N900 so far.

With loads of widgets and 3G N900 doesn't last long for me. But I'm fine with it as that's a trade-off for the ability to have pocket PC with me.

My battery drains empty in about 12 hours now without using it, it's just 12 hours of standby (GSM and Wifi on). Did a complete reflash (incl emmc) two weeks ago. It makes no difference if I set the max cpu to 600 or 850Mhz
Anyone able to see the problem ??

Powertop 1.13.3

I get between 24 and 48 hours depending on usage, can be lower if my daughter wants to watch a movie 
How I got that far:
- no wifi
- no 3G unless needed, so almost always GPRS
- swapiness hack (set to 30)
- overclocked to 500-805MHz and ideal profile
at night, I switch the n900 offline (flight mode).
During the day, I have 4 mail accounts checked every 15min, 2 IM accounts online and calendar/contacts synce every hour. Some websurfing, mail reading, 1 or 2 phone calls and some chat sessions.

I have noticed a similar decrease in battery life that has not been addressed by a reflash of image and eMMC. Haven't been able to track down what the issue is with this huge difference in power dissipation.

About 3 days with medium use using the swampiness changes, kiiling the indexing, killing apt update checking and clocked for 250Mhz-1GHz.
Hard usage (n64 games all full 1ghz) about 4-6 hours of play time.

what exactly constitutes "standby" for the device?
