Thanks for the share, but there really is no need to go through all that and sacrifice such and such just to save battery life. If you're using CM7 the Optimus M already has good battery life and performance and all of that extra work is really not needed. I have my CPU set to a Min of 245 and the Max set to 787. I use my phone heavily through the day and I get a good 20 hours out of it..
I also leave wifi on at all times when im home because it actually uses less battery than 3G, because when 3G is on it constantly searches for towers which ends of up using more power. I have my WiFi sleep policy set to never, so it always stays on when the phone is sleeping which ends up saving a ton of battery because 3G stays off as I said and will say it again 3G uses more battery power than Wifi. Of course I turn off my WiFi when im not at home or at a place where there is a strong wifi network.
You provided some good tips, but as I said that really isn't needed, its too much. People should be just fine if they do the basics such as turning of haptic feedback/dialtones and having the screen timeouts set to the lowest with the brightness at about 50%
Thats how I get 20 hours out of my phone with heavy usage.
