Yet another battery drain problem...
 

I bought my N810 in February, and until two weeks ago, the battery lasted normal (about 4-5 days with normal use). But suddenly i have the usual problem, the battery ends very very quickly. Yesterday i locked it at 12:00 am with 49% battery, and tomorrow morning (10:00 am) it had closed.
My thoughts:

1. Some days before i notice the problem, i had reflashed the device and restored from my backup. I don't think i did something different from other times.
2. I have searched for my apps, and i don't have something that eats the battery (except a new version of an app has such a bug). If it' s needed i will give a list of my installed apps.
3. I reformated the internal memory and my memory card. I also tried without my card and didn't saw big difference, just the normal 0,3%/hour of my card
4. I think it can be a software problem and my device cannot go in powersaving mode as it should. Could it be a problem with systemui or mce? Can i repair this without reflashing again?
5. Finally i thought something that i read somewhere (probably in this forum). The last two weeks the weather here is very warm. Sometimes i see that cpu temperature is high. For example now the room has ~27,5 C (81 F) and N810's CPU has 37 C (100 F). There wasn't such a difference before (i don't know if it's normal).
6. I don't want to reflash again...!

Usually my main processes are:

• hildon-desktop - 16-31 MB - 3-5% load (with load-applet opened to watch the processes)
• hildon-input-method - 11 MB - 0%
• systemui - 10 MB - 0%
• Xomap - 7 MB - 0%
• browserd - 7 MB 0% (why does this run???)

I hope i wrote all the information needed, so to solve this problem.

NOTE: I know that there are tones of threads about this problem, but nowhere is a solution. I created this thread with enough information. This problem should be solved. Where are the developers? Nobody knows what is happening?

Hey, nobody?

Metalayer-crawler? (Is that most dubious program still part of OS2008?) If you still run it, disable it.

Re: Yet another battery drain problem...
 

Applets are the usual suspects. Disable them and see if it helps.

connected to a "power managing" Wireless Access Point?

Oh men, i' m not a newbie. I 've done all of them...

Re: Yet another battery drain problem...
 

Do you have a status bar applet to warn you about excessive CPU usage?

Re: Yet another battery drain problem...
 

Yes, i have the load-applet, in the first post you can see the first processes, i have not notice something strange with cpu usage

Re: Yet another battery drain problem...
 

i had the same problem,but now the battery-life of my NIT is perfect.what i can say is:
1. the USBcontrol can cause battery drain.
2. if you reboot (by terminal as root, not by the power button) it will surely solve the problem (if there is no hardware problem)
3. don't rely so much on cpu percentage usage!
and finally i suggest you to install the "advanced power" aplication( very useful )
i hope these can solve your problem
(sorry for bad english!)

Re: Yet another battery drain problem...
 

Well, i know that, but i don't use it
I have the advanced power app.
NOTE: Today i noticed that sometimes the cpu frequency went to full (400 MHz) without reason. I run "top" and saw that maemo-launcher was 1-6% cpu usage.
