iPhone 5S : Side by side Benchmark Test of iOS 8.4.1 – 9.3.5 – 10.3.3 – 11.2.1 and iOS 11.2.5 Beta 2

This test uses various benchmark apps to test the performance from iOS generation 8 to iOS generation 11.
All devices used are iPhone 5S 16GB devices, all fully charged
but with different battery wear, as seen in the test.

Does Apple slow down the iOS version on the 5S with every new IOS release?.. We know they have implemented a CPU throttle for iPhone 6 and up, but not on the 5S. But do they throttle it some other way?

Let’s test.

This test does not show the UI smoothness as I need 5 index fingers to do that test, and today I only had 2.

This will be the last video in 2017… So Happy New Year and see you again in 2018.

  1. Even though Apple does not support downgrading at all, I think it would be a good idea if they sign the latest iOS software for each major update so the users could go back to at least the previous version of iOS if not even more. Yes, restoring from backups after downgrading could be problematic but this would be for advanced users anyway and the users would be warned by iTunes before to do so. The ultimate choice should be on the users not on a manufacturer. What are your thoughts on this?

  2. If you are going to compare them side by side like this, you should have started by first replacing all the batteries, without it, the test is unreliable as you pointed out. The same goes with computers, update and upgrade them yearly or fall behind.

  3. Very interesting test. Thanks ever so much! It is interesting that after all the performance change is a mixed bag based on what the hardware of the time was most specialized with and how other tech (see html5) have evolved over time, actually improving.
