And metered data. I would be very aware if my phone was eating my data plan via constantly recording audio. Even a measly 12kbps audio stream adds up to nearly 4GB/mo if recording 24hrs/day.
Non-techie users would absolutely notice that their data and battery is being used up in the background pretty quickly. Further, the cell networks simply could not support that kind of usage from every single subscriber at the same time.

The feds have been using cellphones as full-bore wiretaps since the early 2000s when they used it on mobster's "dumbphones". I'm sure they've figured out clever exfiltration techniques on smartphones by now. Especially considering how willing the ISPs/telecom companies are to bend over backwards to hide surveillance. Even 3g/4g wiretapping is probably feasible.
