Phone has 6 cores, only 2 are being used. For power saving?

My phone has a Snapdragon CPU. The specs say it has 2 cpu's?

  • 2x ARM Cortex A57
  • 4x ARM Cortex A53

So I used android app CPU-Z and it says 4 cores are being used, the other 2 have stopped. Is it just that the extra 2 will kick in once the phone is under heavy load?

I don't know this for certain, but I would argue that they would activate more cores as the load heightens. It's very likely for power consumption purposes; I'd imagine the two processors load balance to consume less power. 1 CPU running at max capacity vs. 2 CPUs running half capacity probably draws far less power and outputs a, relatively similar, result. 


All speculation though, I'll likely be reading up on this tonight to verify. Haha.
