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?
