Try any voice recording app for a few hours, now use the facebook app for the same number of hours. The impact on battery life of a mic actively recording alone is very noticeable, so noticeable that your phone has a special chip just to recognize patterns similar to “hey siri”.



It would not need to record high quality audio and could maybe even take advantage of that same chip? Just thinking out loud here - smaller, crappier audio would also be easier to send back unnoticed (or instead of even recording audio it could be transcribing on the fly to a text file using something super basic and easy with low accuracy)

Please, stop with the sarcasm.

Okey, let’s say they manage to record us without a huge impact on our battery life. Now, how do you send these recordings or even the extracted keywords from a popular app, a client installed on devices controlled by the users and susceptible to reverse engineering and network traffic analysis without anyone noticing it?

It’s just too much risk and they don’t even need it, see my relevant reply here: https://news.ycombinator.com/item?id=32950204#32953216.


Great question! I'd love a peek at their source code to figure out these answers too!

I swear that comment is sarcasm free.
