I doubt it, it's clearly batched & a bit lazy

  Isn't that exactly what you would see if there was separate hardware that recorded steps, and the main hardware polled it occasionally.

    That’s what you’d see if the raw accelerometer data was continuously recorded and the actual step math was done in batches on that data possibly along with other computations. If separate hardware was already doing all the math up front it’d make no sense to not pull it once every 10s or something, and there certainly wouldn’t be visible lag between opening the health app and the distance / steps numbers updating

      Entire reason to have separate hardware is so that you don't have to wake up the main processor. If you wake up the main processor every 10 seconds you've completely lost the advantage. The idea is if someone's phone is asleep in their pocket you need to wake it up occasionally to check for notifications and so on, but you don't want to be waking it up constantly.
