Test scenario:

Clean install with developer mode so I can access the device via adb shell. Device is on the lock screen, sitting idle, so essentially is should be doing not a lot.

I ran eventstat to see which processes are generating the most wakeups:

root@ubuntu-phablet:~# eventstat 60 1
 Event/s PID Task Init Function Callback
   87.00 0 [swapper/0] hrtimer_start_range_ns tick_sched_timer
   39.05 3759 scopes_ng::Scop hrtimer_start_range_ns hrtimer_wakeup
   16.68 5 [kworker/u:0] hwmsen_work_func hwmsen_poll
   10.00 3951 ubuntu-location hrtimer_start_range_ns hrtimer_wakeup

Then I strace'd PID 3759,
strace -p 3759 -e connect
