and my battery is empty after 24 hours.

and i have to say:
the xorg log process is constantly running with about 4% cpu usage... and the other processes ALL TOGETHER with about 4 %...
so in my opinion the 4% are way too much for one process.
if this process would just use as much as the other (single) processes my battery would last TWICE the time it lasts now!!!

i seem to be suffering from a similar battery drain problem, haven't yet investigated the cause but may do so tonight, turned on my phone yesterday morning around 10am, by 2pm it was down to a red battery indicator, i hadn't used the phone much only some light web browsing - ie 15-30 minutes tops, the phone had been connected to local wifi for most of this time. At 2pm I recharged the phone for the rest of the day made maybe 20 minutes of phone calls and also a bit more light browsing 15 minutes and the battery was almost drained come 10pm
obviously something is killing the battery just not sure what, this was probably the worst battery life i've experienced since receiving the phone

last night i flashed eMMC then flashed the PR 1.1 image so i could run new firmware from scratch for first time.
Any way since flashing the newest image and starting from clean today i got my first ever full day use on one charge and i still have 1/3 of the bar left.
I think we have all installed something what is really killing the battery b/c i cant see how new firmware could improve my battery by 12 hours alone

Yesterday I was thinking to reflash it to see if it could fix the problem. It seems it is a possible solution.

As mentioned in previous messages, the Xorg logfile /tmp/Xord.0.log is always running and using a lot of CPU. Is it doing so also after the reflash?

Thank you for all the information!

That sounds normal. I have experienced a drain today. Fully loaded it yesterday, came to work today and in the afternoon it was almost empty. A few days ago, reading this thread I looked at CPU usage and mine is steadily around 15%. I saw another one in this thread being around that number. That isn't tight, right?

Could it be apps? I did install quite some and I'm deciding to get rid of them to be sure.

mhm... in idle the cpu usage is usually at 5 - 10%... and thereof xorg log uses 2 - 5% ://

I would be suprised if xorg would not use any cpu
Itīs like backbone of your GUI.

If i remember someone said the battery doesnt fully charge, it hits 90%. So what they did to solve this was pull the battery out, hold power button for 30 seconds, and put the battery back in, dont power up but it should start charging even further, can anyone confirm? or have tried this?

but it wasn't that cpu-hungry before PR1.1?! o.O

someone mentioned that they have added the -logverbose option....

I think it would be useful if people reportng xorg cpu usage stated whether it was obtained by running top from an ssh login, or via top viewed on the terminal running on the N900 gui (and therrefore itself using xorg cpu resource).

If the latter, one might expect true idle usage to be lower, of course
