I think you’re thinking of “adaptive sync”, which is more of a gaming thing and only works when the app is fullscreened.

Adaptive sync and variable refresh rate are the same thing.

Video of the monterey beta shows it works without being fullscreened. https://www.reddit.com/r/macgaming/comments/o1954n/adaptive_...

I don't know to what extent the display itself needs to be different, but hopefully Apple planned ahead.

People with kids. I probably watch an equal amount of video on my phone and my 80in+ TV.

I don’t understand how you came to that compromise.

Sometimes you want to watch video, but you don't want to lug an 80-inch TV into your room.

In general, I moved from Android to iPhone a couple of years ago and must say the battery on iPhone lasts so long compared to my old Android phone that there's no comparison really. Apple's work on iPhone battery management is impressive!

Sure, but there are a 1000 android phones, some that cost $20.

I switched from Pixel 3 XL to iPhone 11 Pro and the battery life was way worse on iPhone. It's about half as good as the Pixel was. It was like that on day one. It was my single biggest gripe about the iPhone.

Maybe just more efficient since the A14 already had AV1 and HEVC support. https://www.cpu-monkey.com/en/igpu-apple_a14-180

> the A14 already had AV1 Uh, I'm gonna need to see a reputable citation for that claim.

Yeah I tried to find another source and could not find anything. Does anybody else know? I just see a lot of posts complaining about CPU usage with AV1 on a M1 macbook.

This is a little presumptuous or possibly a misunderstanding of the parent's comment mentioning "old Android phone". It's entirely possible that the person did a lateral generational phone switch, but you've assumed that they upgraded to a newer phone. I love older generation phones because they're so cheap and your car comparison is perfect because buying a phone new IMO is one of the worst financial decisions you c…

Talking about how expensive the phones have become lately, the max out specs on new iPhone 13 Pro Max costs $1,600 and if you add taxes it would be $1,760!

Your 10% sales tax is robbery. Where is that ?

I'll be carrying my charger with me. These numbers are great on paper, and sure they can reflect the overall trend of higher battery life, but are not examples of real world results. I wouldn't be surprised if these results are on airplane mode with the brightness locked to the lowest setting and the volume off with no Bluetooth accessories. The title says "video streaming battery life" however the website actually s…

I've been running my M1-based MBP since April I've been able to use it for well over a full work day (on the order of 12+ hours) before dropping to 30% battery (from a full charge) And that includes 8+ hours of using VDI, streaming video from YouTube, random other web browsing, etc My iPhone 11 (if I'm not running some poorly-optimized games) will run for over 14 hours between charges of "constant" use (streaming aud…

> hard to believe that the two-generations-newer, more-efficient (and powerful) A15 + larger battery is not going to be more performant

The last generation, 12, had less battery life than its predecessor :p

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

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

My ip12 has shown 1.5 Gbps, that’s 4 hours of Netflix content per second…
