If I understood, the timer coalescing can push timers around to produce spurts of activity followed by quiescence; this results in better overall power performance. It *might* cause problems with a high-frequency heartbeat.


You pick the "drain my battery real fast" option.... Also in the past known as "higher performance" to remove the delay in the morphic polling loop.
