Not in flight mode
I have no idea what is going on, but it's now been 52 hours without charging and I am at 50% battery. It did not drop over night at all. I'd bet a phone call would drop me to 40% right away, but I think I'm gonna be able to get well over 60 hours out of that one charge. So, Psyki, I'm giving you all the credit. Nothing's changed from before where I was getting 16 hours on a charge except for putting your ROM on.
