No, i dont have 3G on...Anyway, tomorrow im selling it and i already have a HTC Desire...
Thanks for everything!

I also noticed a recent battery drain.. normaly my battery lives for about 40+ hours but now batterygraph showed me it had lived for about 12h. I checked "dmesg" in terminal and it showed:

"dspbridge: timed out waiting for mailbox" and looped that message. I also found some strange processes in top like "kondemand/0" and stuff. The vibration when i clicked the screen was wierd. I am not sure why this happens but i tried "modprobe -r dspbridge" and it stopped. Problem is that i need to do this now everytime i reboot.

And by unloading the dspbridge module i probably will encounter some other problems.. like camera or other graphical functions. I have not noticed anything yet.

By using Stkeeps battery diagnostic script (think it was Stkeeps) i have noticed a significant raise in battery use while idle.

Same problem, last 3 days or so. Full charge in the morning, need to charge it by night time the same day as it's almost empty. Hoping rebooting will fix it...

dsp is used for audio decoding. So, try to kill pulseaudio, tonegend and mafw-gst-renderer.

It is just consequence of many process switches. And process switches are usual during audio work.

Mhm... are you using Duracel Ultra?

I had some horrible battery problems as well (4 hours then shutdown). I installed an app called Conky (from dev-testing I think), and it showed that there was a process running that was continuously using 90% of my CPU and draining my battery. I avoid the program now and my battery life is much more normal now. Install the program and see what it tells you.

I hit an odd glitch yesterday where my wifi router stopped giving out DHCP IPs. It still showed it was available, and routed for devices that already had an IP, it just refused to give out new leases. (Most of my devices are DHCP, but are mapped by MAC and have a non-expiring lease.) When I came back from work I was around a few hours and my phone started beeping that it's battery was low. It apparently kept trying to switch over to the local wifi and ate a lot of juice doing so. Something like that would kill any device though.

Moral of the story: Sometimes it's not the N900 that's to blame for it's power usage. It could be someone nearby has setup a new wifi router or a bluetooth device that's constantly pinging your N900 and waking it up, making it eat battery.

Just something to think about.
