It's as natural and unavoidable a fact 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 bit hyperbolic, as devices fundamentally continue to work, but eventually everyone will stop receiving updates. Many users with older devices even stop updating them even before the last one. This version is supported precisely because these updates generally slow down the device and have less battery capacity.
In case of iOS 11, O iPhone 5s It is the oldest device to support Ma's new system (it was launched in 2013 four years ago) and therefore the one that will most certainly suffer from running it. But the owners of this model need not worry so much at least if we take into account the results of this test conducted by the Ars Technica.
Every year, the site is testing the new version of Ma's mobile operating system running on the older device it supports, and things have been improving year after year since iPhone 4 delivered poor results with iOS 7. Now , the iPhone 5s running iOS 11 achieved a relatively good mark as good as that achieved by the iPhone 5 running iOS 10 last year.
The test is very useful: staff times the time it takes for some apps to open from the moment they tap their icon until it's fully loaded and usable, first on the previous system and then on the new system (in this case, iOS 10.3.3 and iOS 11). Then the same measurement is taken at startup time.
The iPhone 5s results are as follows:
As you can see, the loss of agility with iOS 11, in some cases, quite small (Safari and Messaging) or even nonexistent (Camera). In fact, the iPhone 5s running the new system is much slower if we consider the startup and 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 changed in the tenths of a second, and even became faster in the case of the Calendar. In the end, it is important to note that Apple is progressively making its systems less demanding with older devices and, each year, it becomes easier to make the decision to upgrade its old device. .
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 priority to consider than performance, say. if). In other words: If you have an iPhone 5s, you can upgrade to iOS 11 without fear.
