Update: very good battery life with this kernel. Went to sleep last night and awoke by my tp2 alarm this morning: 8 hrs and only 15% usage. I don't disable data at all. Recursion, I disable gps on mine so that's maybe the reason I get better battery life on mine. Yeah, you're not going to get the same battery performance under Android (at least not yet) as that using Vin's ROM. It's getting a lot better so I have been using Vin's Neo half the day and FRX04 with this kernel half the day.
Recursion is right, it gets pretty warm while charging if the phone isn't in sleep mode when I start to charge it. If I force it to sleep (push the power button) while charging, it's not warm. It's almost as though it won't go into deep sleep automatically if the charging is happening unless I force it with a push of the power button.
Very happy with this test kernel thus far.
