Battery life/performance.
Some of you know I'm an avid Juice Defender user and speak highly of it. However, on the MR1 release of AOKP and wifi, I find it's more of a hindrance to the OS, than helping it.
Case-in-point, I went to bed last night @ 92%, woke up at 37%... and I was only asleep for 6 hours.
Doing the math, that's 9% an hour, which is what you should see with moderate use like browsing or anything that uses the screen.
What's odd is I have 'kill all' set when the screen is off, with 15 minute pings (for my Exchange email), so at MOST I should have lost 10% battery.
Now, I keep wifi on at home and have it prevented from being killed, but given the way wifi is supposed to work on these roms, it shouldn't drain the battery if the device is in deep sleep, as mine was.
So I'm going to keep monitoring, but I think there's an issue with wifi and the kernel. I've got Juice Defender turned off for now and I'm going to see how it does tonight. Since it can't seem to put my phone into airplane at night anymore, the app has less and less functionality for me these days, anyway.
