My Battery Experience.
Since 906 I've been running Energy with no/zero/zilch/nada backlight adjustments. Highbeams ON as the Chef intended. No my battery doesn't like me very much but I'm ok with that. Battery life has been, um, decent, at best but liveable. Yes, I've needed my Rescue Charger on my desk at work a few times.
Today, on 920 was a different story. I got 15 hours of light to moderate use off of a charge (took it down to 5%). That is with all the "common" battery mods in place including the latest from maxx134. I think the Battery Hard Reset rootlinux/Strigoi talks about definitely made a difference as well.
I've read every, yes every, post in this thread since I found it back in July so the information is out there. If you want a simple source to find most, if not all of the ones I've used then check out

Now I'm a n00b so I dont have much more than observational "data" to report but during my 15 hours today I made a few short calls, sent/received about 20 sms, browsed moderately, used GPS for a short duration, and have one email account update every 30', two update every 60' and one more update every 4 hours.
Now I'm not saying this is the way to run your phone but IMO this is was a good "test" of the battery mods posted here in this thread. For full functionality you need to use the built in Auto Backlight Adjust or Lumos.
Hope this helps. This is another of my n00bish attempts to give back to this awesome community.
As I've said before, I realize it's possible I'm nuts and have no clue what I'm talking about.
BIG props to all the pros out there that are so patient and gracious and of course the biggest of all props goes out to the Iron Chef himself
