N900 High battery consumption
 
Durring idle time, my device rapidly eat battery. Using CSSU fully updated, no battery patch.
How to find and kill that process, Top command looks OK.

Hey uros
Maybe you can install powertop to see what's eating your battery.
If you search here for powertop you'll see a lot of threads about battery life and also a lot of results if you post the output.
I also have the latest CSSU, KP49 and both speed and batterypatch installed and on top of that OptimizeN900.
I know there's a controversy here on TMO about these patches,
but here's my output with the original battery from december 2009

Tnx Peter, solved. It was GPSdata refuse to shutdown :)

Re: N900 High battery consumption
 
Hi,
my battery drains about 20% in 3 hours, while phone is locked, no wifi, no 3g data, no gps active, cpu usage is low (batterygraph).

I run powertop and saw some differences between my and your output!
First the C1-C4 lines are looking very different, also in "Power domain activity breakdown" part, the dss and core lines show "ON: 100%"!
Could this be the cause for my abnormal battery drain?

I have current cssu, kp49 (also tried pre v50, no difference), no speedpatch, no batterypatch. Tried dsp profile and default profile.

Maybe my battery is just broken? My n900 is nearly two years old, so maybe its time to change the battery?

Here is the complete output of powertop, maybe someone can help me:

Batteries definitely age. Find the battery thread and buy Scud batteries.

It could be your battery but my battery is now 2 years and one month and still very alive...
As for core and dss on 100%, probably that'll be the reason for draining your battery so fast.
There are a few threads about powertop and on the Wiki page you'll find some more information.
I'll hope some experts read your post to comment on how to solve this.
Something to read, here, here and if you search on powertop, you'll see a lot of threads about battery life.

Check your dictionaries guys. If they are corrupted, hildon-input-plugin or the like will keep eating battery like hell.

How can I do this?

Re: N900 High battery consumption
 
Try to ininstall kernel-power-settings to see if there is any difference.

bitrocky 2012-01-30 14:18
Re: N900 High battery consumption
 
I uninstalled kps (copied kernel-config before) and rebooted
it seems to help, I have less wakeups.
but dss and core is still on!?

but now w/o kps, I get a okay-requester with "Package kernel-power-settings not found" on startup and everytime I unlock my phone!?

Do you know where it come from?
