There is a big difference between the local video playback and the streamed video playback on the older model. The new model seems to bring the two in line. iPhone 12 Pro Max Video Playback: 20 iPhone 12 Pro Max Video Playback (streamed): 12 iPhone 13 Pro Max Video Playback: 28 iPhone 13 Pro Max Video Playback (streamed): 25 As far as I know, the new models are slightly thicker and have a higher capacity battery whic…

Maybe a hw decoder? (These already exist, but I mean, really tightly integrated with the browser.) Or some other offloading to hardware? That would be my best guess

Or maybe it was a random hardcoded performance target.

Next version improve it artificially by x% by simply changing the hardcoded var. And boast you device is so much better

It might sound like a tinfoil comment but apple was already caught underclocking older devices 'for the good of users'

I would think the newer 5G modem would help, too.

Maybe. 5G still uses more power than 4G over long duration, if both are enough for streaming. 5G power usage benefits come when you download something, and it simply takes less time.

Aggressive pre-caching so the wireless modem isn't turned-on as long?

This is a huge qualitative difference beyond just the numbers. With a battery life that is longer than 24 hours, I can just have a single charger at home, and go through the entire day without worrying about charging. It basically removes battery level from the things you have to be thinking about as you go about your day.

I would hope that your new phone lasts more than 24 hours regardless. I also may not be terribly with it, but I'd also hope that no one is trying to stream video 12+ hours a day.

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.
