I don't have high CPU while charging. I'm leaning towards a daemon.

Also, pedometer, if it's the one counting steps, is running a loop and monitoring accelero several times a second. That can't be good.

If you need to kill stuff, ps from terminal gets you processes and kill kills them. Killall is better.

Frankly, you should not be there. Killing a drain is last resort. It shouldn't be there in the first place.

Also, yes, TMO search vacuums. I have used Google on many occasions.
