For all of you, having trouble with low battery life using this ROM (just over one day, or so, of normal usage), I might have a solution. (I am using first ROM with 7.8 system, that poloche cooked, posted HERE, if it makes any difference.)
First things first - When i originally installed this ROM, battery life was very bad. A day of normal usage, and that's it. I tried many different things, in one moment disabling dehydration hack seemed to help, but only after uninstalling a number of apps, problems disappeared. I will get back to that. Here is how my Battery screen in settings looks like now:

Battery saver is turned off (except when it turns itself on), Wi-fi is turned on, downloading emails is set to "as items arrive", so no special measures of saving battery. Battery drain when phone is idling is exactly 1% per hour, never more.To be totally honest, it is four and a half days of relatively light usage - a few calls, several SMS messages per day, some internet, mail, etc. But, then again, before that, my phone was practically idling, and battery lasted one day anyway.
And what is most curious, application responsible for battery drain was - Nokia Drive . Since I uninstalled it, problems were gone. So, I forgot about the whole thing, and kept using phone for a few weeks.
Then recently, I decided to install some more apps. And then - what a surprise! Battery drain again. After just 2 hours, battery dropped from 100% to 86%, with only a few minutes of phone usage.
And, application responsible was, believe it or not - Nokia Trailers. I uninstalled it, and problems were once again gone.
So, here is my theory. Branded Nokia apps cause battery drain. How and why, I have no idea. It may be a long shot, but I don't know how I could interpret facts differently. And facts are pretty straightforward - no Nokia apps, battery lasts four days. Install any of them - it drops to just over a day, and nothing else is changed on the phone.
Maybe someone should try it out, however stupid it may sound...
