as an example (taken from this thread).
system A needs to wake up to get a battery reading, store it and go back to
sleep, It does so every 10 seconds. But when it does so it only runs the one
process and then goes back to sleep.
system B has the same need, but wakes up every 10 minutes. but when it does
so it fully wakes up and this allows the mail app to power up the radio,
connect to the Internet and start checking for new mail before oppurtunistic
sleep shuts things down (causing the mail check to fail)
System A will last considerably longer on a battery than System B.
Exactly, thanks for pointing out the specific example :)

This does not affect suspend_blockers nor does suspend_blockers
interfere with that.
Suspend_blockers allow the system to suspend ("mem">/sys/power/state
suspend), when the userspace decides that the device is not in use.
So implementing suspend_blockers support does not impact any
optimizations done to either system A nor system B.
