Interesting comment on the battery impact of Siri. Did you notice improvements when you turned off Siri entirely or just the "Hey Siri" functionality? I find it quite odd that Siri would take up battery even when not running (given that "Hey Siri" is disabled).

I haven't tried partially disabling Siri (always completed disabled it or fully enabled everything), but I thought the "Hey Siri" feature worked only when plugged in? Maybe I'm confusing it with a different feature.

  That was an iOS9 limitation.

    That was a phone limitation. The iPhone 7 had the hardware for always on listening.

      Ah that must be it. I have an iPhone 6.

      My 6S+ supports this as well.
