Just wanted to update on this. I know I had posed the question about the battery life yesterday so let me tell you what happend:
I went to xda and found the Glaxy S theme and wanted to try it on my Optimus S. The bad thing was that my phone didn't like it and got stuck on the boot animation so I went to go restore my nand and realized it was the TR 1.8.2 nand and not my CM7 nand. Anyway, I had to end up reflashing Zefie's CM7 on my phone from scratch. I am also using zefie's custom recovery, so I wipred data, cache, went to mounts and storage and formatted everything possible (except sdcard) and reflashed cm7 (per instructions). Charged my phone overnight and today I have been using my phone (as usual - no heavy usage) for 3 hours + and I'm still at 100% battery life. What gives? lol no idea what i did or what happened.
I'm not saying this is a fix, but something happened where my battery life is no longer at 40% 3 hours into my day. Any ideas?
Any further update for how the rest of the day went? My day with aospCMod was extremely poor, but mostly because I was messing with it a lot and changed the governor to be slower reacting (which I didn't realize means it would take longer to slow down as well!). But I'm giving it another day of trial to see what I can do about it now that it's all set up.. After that, if it's still bad, I'll go back to scott pilgrim and try to optimize that more than i had it..
