There is some speculation that the iPhone 13 running in low power mode, that the 2 performance cores are completely shutdown and only the 4 efficiency cores are used. With only the 4 efficiency cores, the A15 still performs on par with the Snapdragon 888. The A15, running in low power mode, is only using about 3 watts of power as compared to the 888 using about 9 watts. This video shows how powerful the A15 is in low power mode and able to maintain a perfect 60 fps. The A15 is a beast of a mobile CPU.
