Does the new version improve the performance of your iPhone?

The latest iOS update is 15.4. It arrived a few days ago for all iPhones and iPads supporting iOS 15 and iPadOS 15. A good batch of new features are in the game, as described here. Some changes are more significant than others, however, with the update, including the possibility of unlocking your iPhone with Face ID and a mask on your face, updating your iOS device via 4G or integrating your vaccination pass against COVID-19 in Wallet (Maps).

But who says a slew of new features also sometimes says the arrival of new bugs, or even damage to the general performance of the system. It is this last point that wanted to test a YouTubeur that we are used to following at iPhon.fr, iAppleBytes. The latter tested iOS 15.4 on 8 different iPhone models, iPhone SE (2020), iPhone 6s, iPhone 7, iPhone 8, iPhone XR, iPhone 11, iPhone 12 and iPhone 13.

He compared, on each of these machines, how iOS behaves, in version 15.4 and in version 15.3.1. We can see live manipulation tests of the system, at the finger and at the movements. Find Geekbench test results for each of the devices taken into account in the measurements.

What conclusions?

Geekbench 5 scores only reveal no big changes when moving from iOS 15.3.1 to iOS 15.4, neither better nor worse, for the iPhone 11 to 13. The iPhone XR loses 30 points in multicore by moving to iOS 15.4, which is not not really significant.

The biggest losses are to be noted on the side of the iPhone 8, which goes from 2267 to 2030 points after update. The iPhone 7 notes a drop of 70 points. For iPhone 6s the drop is more minor, and for iPhone SE 2020 there is simply no difference.

If we look at the navigation tests on the iPhone, we see performance slightly behind on older iPhones running iOS 15.4 compared to what the previous version of the system offers. It’s very lightweight, but some apps feel longer to open and a little less fluid. Nevertheless, as the author of the video points out, the differences are obvious due to a direct comparison. In normal use, these slowdowns should not be noticeable or in any case very little bothersome.

On more recent iPhones, from the XR, nothing special to report, iOS 15.4 does not change anything in terms of performance.

What about your side, have you noticed a decrease in fluidity and/or autonomy, or on the contrary improvements in one and/or the other of these two areas by switching your iPhone or iPad under iOS or iPadOS 15.4?
