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.

I was surprised to see some of my younger relatives using Youtube as their free music streaming service. You can find almost any song, with static images in the video. They listen with their phone in their pocket, while streaming regular YouTube. One of them had an android phone that let you disable the touchscreen with a switch, along with some way to turn off the screen. I have to admit I do the same sometimes with…

YoutubeVanced allowed this. You could disable the video stream and just stream the music.

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.

When I'm watching the kids or doing chores I am often watching some "background noise" TV at the same time. If I'm not at home, the phone is the obvious choice. If I am at home, I'm often moving from room to room and it's a lot easier to just take the phone with me than constantly switch devices. And when I'm laying in bed at night feeling lazy, I just watch on my phone instead of moving out to the couch in the living room (sometimes, and sometimes I say in the living room and enjoy my big TV).

I’m sorry but who watches video on a 6 inch phone today?

When I would commute from Orange County so Santa Clara the flight was often ~40 minutes. Combine with takeoff and landing it didn't make a lot of sense to pull out an addition device but it was easy enough to watch a short TV show on my phone.

They did say during the conference that the new chip had a new video encoder/decider, so that sounds plausible.

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.

Can’t you achieve the same results then by pretending that one long stream is just a bunch of independent chunks and download them separately in bursts? No need to trickle it the entire time.

Afaik that's how video streaming works. You can text it in YouTube and look at buffer length for example.

Edit: my objection is incorrect. We’re in fact saying the same thing. I misread a previous post :/

Not if the broadcast is (eg) HLS[0], so I think the proper answer is: “it depends.”

I watch more on my phone than on tv - sitting on a train, in bed at night etc

Most young people

No

Uhmm, yes?

Mobile is the main format for content consumption on YouTube, Instagram and YouTube, all platforms which are predominantly used by young(er) audiences.

I barely ever watch YouTube (for entertainment purposes) on my notebook or desktop, but primarily on my phone. Many of my friends don't even own a TV or a monitor setup.

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…

They highlighted dynamic refresh rate on screen. So screen can run at 30FPS (half of normal speed) if you are streaming 30FPS content (which many folks do). Or even 24FPS (which now won't need to be converted - nice!).

None of these factors explain why they closed the large gap between offline and online video playback

I am surprised to see someone saying HLS wouldn't work this way. I'm not up to speed on the latest in HLS, but when I used it circa ten years ago, HLS worked by providing parts of a stream as individual video files, so I'd expect this is more true for HLS than a single-file-as-a-stream, not less. Videos were divided into fixed-length files, e.g. 10 seconds each. The playlist file saying what video files to use could list all of the file names up front for every provided quality level.

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!

I don't want to question wether Apple's work on battery management is better than Google's, but want to outline the meta of such statements. In general, I don't think it's good to compare a new bought device with the device you are replacing, since the old device is probably a couple of years old. So the specs of the old one must be worse than the specs of the new one. Another example would be Tesla buyers who are re…

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 can make unless it has functionality you really need. Phone value drops sharply after the first 1-2 years and so I have a lot of fun buying last generation's phones (Android and iPhone) and comparing them to each other. Holding off on the newest phones really shows me how imaginary the price of an absolute brand new phone is.
