So, I'm running AOKP, along with the lean kernel, and honestly, I'm not noticing much (if any) improvement in battery life. I suppose it's slightly better (about 1-2% higher than it'd normally be), but not by much. Is there something I'm missing...? Not to sound like a complainer, or anything; honestly, the battery life has always been perfectly fine for me, even on stock, I just thought running a good ROM/ kernel combination would help out a bit.
Also, it seems like the phone gets hot much more often (and more quickly) than it used to when I was still on stock... What's up with that?
Oh, and just a general ROM question, but once I flash something in recovery, can I delete the .zip file off of my phone, or do I have to leave it on there?
Edit: One more "general" question... If I flash a future milestone ROM, will it reset all the settings I've made in the ROM control?
