It is a fact as natural and inevitable as death or taxes: each year, a new version of iOS arrives and, with it, a new wave of devices leaves life to enter history. Okay, maybe I’m being a little hyperbolic, since the devices fundamentally continue to work, but at some point, everyone will stop receiving updates – many users with older devices, even, stop updating them even before the latest version supported precisely because these updates, in general, make the device slower and with less battery capacity.
In case of iOS 11, The iPhone 5s it is the oldest device to support the new Apple system (it was launched in 2013 four years ago) and, therefore, the one that will certainly suffer the most from running it. But the owners of this model need not worry so much – at least if we take into account the results of that test carried out by the Ars Technica.
Every year, the site tests the new version of Apple’s mobile operating system running on the oldest device it supports – and things have been improving year on year since the iPhone 4 showed mediocre results with iOS 7. Now, the iPhone 5s running iOS 11 has achieved a relatively good brand – as good as the one achieved by iPhone 5 running iOS 10 last year.
The test is very empirical: the staff times the time that some applications take to open, from the moment of touching its icon until the moment when it is fully loaded and usable, first in the previous system and then in the new system (in this case, the iOS 10.3.3 and iOS 11). Then, the same measurement is made at startup time.
The results of the iPhone 5s are as follows:
As you can see, the loss of agility with iOS 11 is, in some cases, very small (Safari and Messages) or even non-existent (Camera). In fact, the iPhone 5s running the new system is only much slower if we consider the startup and the Maps, taking into account the test items.
For comparison, these were the results of the test done with an iPhone 5 last year:
The device also showed changes in the tenths of a second, and even became faster in the case of the Calendar. In other words, at the end of the day, the important thing to note is that Apple is progressively making its systems less demanding with older devices and, every year, it becomes easier to make the decision to update your device. old man.
The advantages, of course, go far beyond performance – the latest systems bring, in addition to new features, very important security updates for navigation in the digital world, for example (something much more a priority to take into account than performance, say up). In other words: if you have an iPhone 5s, you can upgrade to iOS 11 without fear.
