    has anyone done any battery testing on their 6s or 6s plus with Hey Siri off vs on? Coming from a 6 plus to a 6s the battery life has been much shorter (to be expected), but I have been wondering if anyone has switched off Hey Siri and seen an increase in their battery life.

    If so, please share what you have seen. If not, I'll do the honors.

    If you have Siri on, it's always listening, even with hey Siri off. Test this by speaking your command and after the first word press and hold the home button to activate Siri. You will see she still gets the whole command so suspect having hey Siri on will do very little for battery drain.

    That said low power mode does disable hey Siri but also the preemptive mic thing so having siri off will save battery but hey Siri will not.
