    But if I am to remove my widgets and apps... what am I left with?

    I agree, but just removed one at a time to test, if it works then it could be a software bug with that widget..... If so, a bug report could fix it and sort your problems out

    It's really quite simple, if you have nothing running you shouldn't see anything taking cpu in top(besides X, osso-xterm and top).

    Ahem. I want names named so heads can roll.

    An application messing with user settings that way without appropriate notification and interaction should be an absolute no-no.

    I saw this happening right after I set up my gmail account in Nokia Messaging. I usually keep my WiFi connection on "always ask" but after setting up that account it changed to "on demand". I realized it after observing a suddden change in battery usage. I hope I was the only one experiencing this behaviour.

    After a week of excellent battery performance, the problem is back. After I switched to 2g mode and had 3 full days of battery, I figured I'd install a few apps. I got jeweled, puzzle collection and mancala and I updated my fm radio (just installed not played).
    That was yesterday with a fully charged battery. This morning I woke up to the beep of low battery and by the time I got out of bed the phone shut down.

    CPU and Mem usage are close to zero, no active connections, no background applications running...

    I am now pretty sure that something goes wrong when I install a new app or udate an existing one. I can't explain it otherwise...

    I also have this issue from time to time. I make sure i have no cpu hogging app everytime but still sometimes it goes down from 70% to OFF after only 6-7 hours. (I sleep then wake up to find my phone turned off with battery drained) Happens during the day also. Weird.

    I just ran into a similar problem, ran top, then corky and both were showing me that the cal app was eating 76.5 percent of my cpu, and the cpu was running at 100%. Drove me crazy then I remebered I had changed a setting in the cal function, to keep dates for 1 year past. I changed to 1 month and rebooted the N900, and now in standby I am 2-3% instead of 100% and back to 2 days of normal usage per charge, which is a mix of wifi, 3G, txt, voice, pics, games, and a little bit of everything.. hey its still new!! This problem didnt raise it's ugly head till I upgraded to 1.1.. Hope this helps. Craig

    But the thing is in my case that the battery drains while CPU is 97-98% idle.

    And both times it happened after I installed new apps.

    Some of you asked me if I had rebooted. Now if it is necessary to reboot after installing a game why am I not prompted to do so by the app manager?

    And how could a newly installed app like a game, that is using no connections, gps or resources, eat up all the battery?

    Could someone confirm if there is a bug in the application manager?

    BTW, recharging Li-Ion atterieswhen half-empty does no harm, infact it's better on the battery to charge often
