identityserviceD will intermittently use up a massive amount of CPU and drain my battery, do i just accept this or is there a way to stop it from running unnecessarily?

Occasionally my Mac battery will drain faster than normal, even if I'm only doing light tasks or even just letting my Mac sit there. When I open up the activity monitor, sure enough, it's 'identityserviced' using up 90%+ of my CPU. wtf. is this normal or do i need to force quit this everytime it happens so it's not eating up all my battery?
