I’m not sure you understand how animations like this are usually coded.
First, a simple zooming animation should be well within the capability of both of these phone’s processors with zero slow-down or delay. In this video the SE is horribly slow, not just fractionally slower.
Second, these animations are (or should be) coded to execute within a certain amount of time. This allows Apple to choose the speed and quicken or slow the animation to taste. If the SE’s processor was incapable of running the animation adequately then you’d see jerkiness, stuttering, choppy animations or dropped frames but it would still attemp to “catch up” and execute within the prescribed time. That is clearly not the case here where the animations in both phones look completely smooth. It’s that one has been set to execute (intentionally or not) more slowly than the other. That’s why the author of the video comments that the slowness of the SE’s animation is completely artificial and there’s no reason for it.
Again, any A-series processor is more than capable of executing simple zooming animations flawlessly. Apple has been caught out. These suspicions have been bubbling away for years.
Still don't get it clearly.
Ok, equate a single animation speed to a driver in a 2013 model year car doing 0-60mph in 5 seconds. Each person you add to the car is the new bulk in a new OS version as it gets more complex and feature stuffed. Now add a 250lb adult passenger. The 0-60 goes down to 5.2, now add 2 more heavy adults in the rear 2 seats, it goes down to 5.6.
Now get a 2017 model year car with 100hp more (same as a new phone with a much more powerful CPU). No big shocker those times ALL go down, with or without load (the 3 passengers). You have more raw power from the start to compensate.
It's not JUST a single animation. It's the fact that as the OS gets more complex that there is more running in the background WHILE the device is doing that "simple" animation appearing to slow the works down on an older device. It should be no shocker a brand new processor can do it better than one from 3 years ago; especially when the new device was built around that OS (and the one from 3 years ago built around the OS version 3 years ago).
Im not sure why it's such a difficult concept to grasp. Go load Word, Excel, Outlook, 6 Chrome tabs, and a few more memory intensive programs and then go to do something basic like Paint and even on the fastest of PCs you are going to get stutter./lag It's the CPU and memory getting temporarily bogged down because so much crap is running. Same as a mobile OS except those programs are background processes as more and more features are packed into the OS.
There simply is no conspiracy here. There has been ZERO evidence produced other than anecdotal Youtube ramblings (opinion at best); no code from iOS presented, notta, of anything intentional Apple put in there.
At BEST Apple did a poor job out of the gate optimizing 11 for older hardware which will improve with updates. Same story every year; their priority is the new hardware to make revenue as they are releasing since they arent billing old customers for updates.
It's the same ridiculous discussion every year of conspiracy theories and then calling people rationalizing it with fact "sheep," and bickering getting to no end as no one here has ANY control over what Apple does either way. And then all discussion about it disappears after a few OS updates until next major version release. And let's be real, the grass its not greener as even with a few hiccups (I admit there are currently some minor ones, but the .1 seconds do not influence my life that I feel the need to whine about it) iOS is leaps above the hot mess Android is; with no true 3rd competitor out there to go buy.
