This reminds me again how cool phones architecture is. There’s a huge amount of patents around the idea that you don’t really need to have the power-hungry main AP on all the time. Instead, people get really creative around delegating behavior to cheaper chips to save power and sometimes reduce total BoM cost. For example, one that I worked on was around the idea that you could use a minimally featured yet cheap ble chip to detect when one of your paired devices was near the phone. It would then wake up the beefier chip with the full stack implemented, which saves a suprising amount of power. Some of the things you can do when you break out of the software-only box are incredible!
