Somebody in the thread at some point said:
| Just a quick addition to the power topic -
|
| I compiled and ran powertop on the phone yesterday. I know there's
been some
| previous discussion of using tickless kernels on the freerunner (and the
| problems encountered with those), and indeed the kernel was waking up to
| tick more than anything else.

Cool thing to do.

| However, about 25% of kernel waking came because of chatter from the
| accelerometers, which I don't use at the moment (they're a
bell/whistle for
| after I get the phone stable).
|
| Anyone know a way to turn them off completely?

If you don't have the event device nodes for them open, they do not run
the interrupts.

Use lsof -n to see who has them open.
