I seem to recall that state of the art audio encoding can compress voice to 8kbit/s which is a single packet per second, insignificant compared to how chatty your device is. Trivial to buffer and send during a period of activity. It sums to 1.7MB over the 30 minute window in the article graphs which should be visible if it is actually counted. Why would apple or google actually make it count though? They want to spy on you either for their own benefit or because the government forces them to. You say you found it taking screenshots and phoning them home. Of course! It is a surveillance device. Is it worse? Maybe. You should consider it sends everything home. Every keystroke, every touch of the screen, every sample of the accelerometers, every sample of audio. Perhaps only the sheer quantity of data in video prevents them from sending it all. Might be "remedied" with 5G bandwidth.

Audio, screenshots, and some of the other stuff I can believe, but I think batteries need a big upgrade before the data snatchers can get away with streaming video, even at a low bitrate.

I'm also not sure how easy keylogging is these days, is there even a permission that allows it? I supposed there's ways to do it with custom keyboards. Google/Apple doing it themselves would be a pretty big deal.

I think everyone acknowledges that chrome sends every keystroke in the address bar home. I don't keep up with the spyware so perhaps it is now every keystroke in the rest of the browser. It isn't much of a leap further that their operating system does the same.

Knowing how digital advertising works, it's more likely that a payload is delivered to the phone in some app or by os or by browser that has a dictionary of keywords paid for to be associated with specific ad campaigns. If the device detects that term (via sound, search, or media) it triggers a message home as an analytics to target you and your device now calls for those campaigns.

If it works like that, why aren't the app companies describing exactly how it works to advertisers in order to earn their business?
They describe how everything else they do works in great detail if you're someone who buys ads.

What makes you think the raw audio stream needs to be sent anywhere. Modern phones are capable of doing keyword extraction on-device.

You need to know what keywords to listen for before discarding the audio data. An advertising giant might know but a government doesn't.

This conspiracy theory has been around for a lot longer than phone hardware has been capable of doing that.

  The Chrome Browser can transcribe audio into text, with what I consider good accuracy. It's well out of the realm of a conspiracy theory when it's been demonstrable for a couple decades.

  Don't forget energy usage. The phone would need to be on high power mode all the time to run those kinds of algorithms. There's a reason "Hey Siri" has dedicated low-power hardware - it means it can work without burning through the battery.

  It can work by burning through the battery. When you have a browser open or any number of apps, some of them are certainly detecting.

If that were true why are cell phone voice calls still so terrible?

Because cellular carriers keep the same pace as a snail on vacation.
