Switching apps, latency for apps to restore state once you switch to them, latency for the camera to save a photo, latency on pretty much all interactions is noticeably better.
I'm not talking about dropped frames, Apple have always been good at ensuring a fluid user experience, but there are lots of points where apps can take a few seconds to do something on older hardware, or do it nearly instantly on newer hardware.
Does a few seconds make a difference? To my life, no. To my enjoyment of using the device, yeah. Whether it's worth frequent upgrades or not is a value judgement we can only make for ourselves, but there are many perceptible differences devices more than a few years apart.
Probably not the best examples because they have bloated webapps that are pretty slow/laggy.
If you're on desktop, use the old reddit layout, and install RES if you can.
Nearly every complaint I see about reddit's UX is because of people using the official app (Seriously, how is the official app the worst one?) or the new reddit UX.
As for Twitter, I've never felt its website or app to be slow on mobile.
If you have to download an app to use what is fundamentally a website, that website has failed miserably.
Reddit on a desktop does this kinda weird jiggle thing.
I thought my eyes were going bad, and then you notice the page is still loading after 10 seconds.
Voice latency is a big part of why people type on a telephone, instead of talking on it. We're entering a second generation of people who have no idea what it was like talking on an analog POTS network. They'll even argue with you, claiming their VOIP connection across the ocean has the same quality and latency as someone talking on a hard line to a neighbor down the road. Ummm... no. Not even close. Sadly, the older generations didn't realize how good they had it.
Remember when phone companies used to compete on quality? AT&T's "You get what you pay for" campaign. Sprint's "So clear you can hear a pin drop" campaign. MCI's "Static-free coast-to-coast."
Today, it's "We'll bundle six other services you don't want with your phone service and charge you a $1,200 for a new phone. Aren't we great!"
And personally, I'd rather have a little latency added than have to talk over a shitty POTS line. I always had a hard time understanding people over it.
That was AT&T's method. AT&T even had a demo line that you could call that would play various sounds and music and you could press a button to switch between the modes to hear the difference.
But you can't really think that a POTS call sounds better than a modern VOIP call?
Yes, I can. Because just before the pandemic, I was able to use a real POTS network in a remote part of the country. Called from one ranch to another over a rural switch. And it was awesome.
The quality of a call is about more than its audio bandwidth. If that was true, then people wouldn't be able to tell the difference between an iPod and a vacuum tube amp. And, again, latency is a massive factor, as is true asynchronous communication. Arguing over POTS is a whole different thing than arguing over VOIP.
People who defend VOIP claiming it's just as good have never done a side-by-side comparison. The only advantage VOIP has over anything is the usual "make it cheaper" race to the bottom.
These days so much of it is routed over IP, which is where all the latency got added.
So, its hard to know what your "ranch" actually was.
OTOH, its hard for any hardwired system to be half as bad as your average cell phone which are dealing with constant channel quality issues, which results in the robot voice (for lack of a better description), and all the broken up audio, or simply silence that one frequently gets from a cell phone. Basically cell phones suck for actually talking to people. <shrug> But once again, convenience trumps quality.
Battery in SE 2 compared to 3 is 11% larger (1821 mAh to 2018 mAh) but advertised "video playback" duration is 15% larger (13 h to 15h). This is unlike the comparison of SE 1 to 2 in which an 18% larger battery (1624 mAh to 1821 mAh) was entirely eaten by screen, etc. for no improved playback duration.
13 h 15 h
I think if this rumor were true then Apple would not have launched the iPhone SE with the A15. There was really no reason for the SE to have the A15 but they shoved it in there, anyway.
TBH the Apple lineup has never been more confusing.
Then again I upgrade phones if they come out in green also. My last upgrade was for a 120hz screen refresh rate.
If you game or edit pics or anything else that needs a faster proc, sure, you'll notice not having the fastest phone. But if you email, reddit, HN, twitter, etc, you're really not going to notice much.
Rumors are the iPhone 14 will have the same A15 and only the Pro will get the A16. I think you'll see a bunch of people freak out about this, but honestly, phones really don't need to be faster at this point.
