So since some of you were looking for it, here's the battery tweak again that I originally posted deep in the belly of the Scott Pilgrim (CM7) thread:
I originally found this information on the xda forums.. I've only tested it in the CM7 build, so it may or may not work in other ROMs. And it's been days since I first did this.. I can tell you that my battery did go from about a max of 10 hours, to nearly a whole day (24 hour period) if I kept it to light use. The highest I've seen my TWS% go during the course of a day was about 20-25% (some of my classes are in old stone buildings built to double as fallout shelters, so even roaming doesn't always work). From what I've seen around on these and other forums is that many CM7 builds (probably mostly the unofficial ports) don't have that great battery life compared to some other more established and polished ROMs, but at least this will get you to a more reasonable position battery-wise.

- Open up the dialpad, and type:
*#*#4636#*#*
(the numbers are for 'info'; don't press call, it should automatically go to a 'Testing' menu)
- Go into 'Phone information'
- Press Menu, and select 'Select radio band' (this will result in a force close, but that's what we want.. just keep going.)
- Go back into 'Phone information' and scroll down to the bottom'. It will probably still say 'CDMA auto (PRL)', but the problem is this is probably a visual glitch. Or it might say 'Unknown'. Either way, switch it to something else, then switch it back to 'CDMA auto (PRL)'. Then you can turn off the radio and turn it back on with the button right underneath that.
- At this point, the fix has been applied, but it would be a good idea to clear the battery stats to get a fresh start. So boot into recovery and do that, then reboot. The fix *should* stick after this reboot, but I think it didn't when I first did it. But assuming it does, then you're golden. It will be like this for all other reboots. If it does not, then just do it again. You can tell if it worked if when you go into battery usage, and go into cell standby, the TWS% is much lower. I charged mine completely overnight after applying this fix and have been off the charger now for over a half hour and TWS% is still at 0% (even though cell standby is at 46% (but that's not a problem at all..), and my battery is still at 100%. Before, by this point, it would probably already have dropped 5% with the same amount I've been using it.
