Perhaps they’re assuming a cinematic frame rate of 24fps for streaming video and matching the refresh rate to that versus whatever refresh rate an iPhone 12 Pro has - guessing 60hz? Still seems a big increase but maybe the combination of the variable refresh display, larger battery and refined 5nm node (TSMC 5NP) all add up to something substantial? I was wondering if this was also factoring 5G in given last year’s 5G modems were noted as particularly power hungry. I’m guessing Apple is testing on WiFi though.
