Listen for “hey Siri” impact on battery life?

[JulianL]

Has anyone tried to measure the effect of enabling Settings/Siri/Listen for “Hey Siri” has on battery life vs having that option disabled? Series 6 running 7.0.1 of particular personal interest.

I don’t recall seeing any posts addressing this aspect thus far. I would imagine it would be minimal and no more of a drain that the hand washing reminder using precise location 24/7. I have everything turned on on my series 6 and have been enjoying great battery life.

My S5 and S4 nearly always lasted from wake up to bedtime, so I never felt need to measure with it off.
