Siri Audio battery usage in settings, even when I have Siri completely off?

I think I figured this out. Feel free to try to prove me wrong. When I use voice dictation (using the mic button on the keyboard to speak into the phone and have my spoken words transcribed into text), it stays "on", basically keeping an audio channel open, until another application uses the phone speaker, at which point the dictation service stops "running". I think this is what my phone labelled as "SIRI" under battery drain. I figured this out because sometimes, on days when "SIRI" was using a lot of battery, when I would get in my car and connect my phone via bluetooth, it would immediately show that I was in an active call with my own phone. This will make sense to you if it ever happened to you. I figured the phone was basically still trying to "listen", and when I connected it via bluetooth, the "listening" switched from the phone to the bluetooth connection.

So, I started trying to make it stop. I discovered that using any music app would terminate that process, and my phone could then be connected to my car via bluetooth, but not actively on a call with my phone. And from that point on, things stayed normal. But if I used dictation, sure enough, the next time I connected to my car via bluetooth, it would go back to that strange connection where I was on a call with my own phone.

I repeated the experiment many times and it always produced the same result.

Conclusion: disable or stop using dictation (voice to text) to type on your phone.

And wait for Apple to get smart enough to figure these things out for themselves and fix them.

I am wondering if this has to do with using Bluetooth for audio. My theory is that the iphone (with this OS) does not have anywhere to assign the battery power required to transmit Bluetooth audio, so it is classified under "SIRI audio". I have noticed a correlation on my phone with Bluetooth audio use and the appearance of "Siri Audio" in my battery stats. Going to do some experimenting over the next couple of days...

Found the fix! If you have turn Siri off turn it back on when you go to the audio selection or suggestions you will see that it is set to all ways on. I set mine on hands-free only, turned Siri off. Restarted the phone and battery usage went back to normal.

Nope, that's not it. I don't know what it is but I think it is the iphone mistakenly labeling some other process as "SIRI"

Holy crap! I've been trying to figure out the battery drain for months! I have the same active phone call indication when my vehicle connects! I think you solved it!!!! Thank you!!!!!!

This is exactly what happened to me. I played some music so now I will check to see if the weird bluetooth call to myself goes away.
