face unlock wasting battery when phone is already unlocked

[rejetto]

I was trying face unlock and I noticed the thing is triggered even if the phone is unlocked.
Seems like a useless waste of battery to me.
Am I missing something?

I think it's using front camera for smart screen option to extend display timeout
