That being said, with LithMod and Chevy's ULV kernal at 600/250 I've been getting the best battery performance yet. I still don't see how anyone can get 30+ hours out of their phone with "moderate" usage. Maybe with strictly standby...
What's the secret Peter?
Using JDLFG's LV 800 kernel and JuiceDefender I made it almost 34 hours yesterday. Yes, a lot of that time is with the phone not doing anything, but I do use it to stream shoutcasts while driving and the usual browsing/emails etc. Heavier use will certainly shorten that life, but I think to say Lithium Mod has battery drain issues would be incorrect.
For what its worth I run at 800/300 normal, 300/300 standby, and have JuiceDefender scheduled to turn off the radio entirely between midnight and 7 AM. Wifi is only turned on when I'm at home in the evenings and bluetooth and GPS is always off. I can't imagine having autosync disabled.
