List,

Try to collect wakeup on Android phone when phone is in suspend mode.
run daemonize powertop > /data/powertop.log &

There are some wakeups when phone is in suspend mode.

The question is how fast the background process will be resumed after CPU is up?
 
What I see is CPU wakeup is too short and my powertop& does
Not have enough time to run and suspend again.

Any idea to collect wakeups in my situation?

Thanks.
