Haha, just to mention, I am a mathematician I gave an approximate number when I said 5 hours. The worst is 1 percent every 1-2 minutes. Lets not talk math though . When it comes to flashing, I am a Mobile Software Engineer, so not a lot know more than me. In fact I am at work right now, flashing some BS motorola phones. Anyways, thanks for your critics and help. I guess flashing will not help, as it does not affect the battery management. I will try things like running it at 900 and so. Thanks again.

Well to put it in short way
- Uninstall all apps that you do not use
- Disable all apps that require connection (IM, VOIP, Skype, e-mail,widgets etc.)
-Disable all schedulers that take connection in some intervals
- Use only 2g
- Do you use any folder/categorization application?

Test for couple of days to see if battery depletion is still big. If not then one by one start using widgets / apps.

And on some level I find it bit offensive that you are using devel/testing repository and come off with question that you should be able to debug yourself (because well, you are using devel/testing).

Learn to use some basic analysis tools like:
top
htop
powertop

Thanks. And for the offensive part, I have used all those commands, and I check battery life using the x terminal. I have been troubleshooting myself for a while now, with no clear results, and I thought the forum could help. NO means to offend anybody.

Since you're a Mobile Software Engineer, maybe you can answer my question: I was assuming that flashing could fix some random corrupted file somewhere, and a corrupted file could affect battery management. No? That was my theory, anyway.
