How does iOS 13 perform on older iPhones, iPhone 6S and SE?

By  Sigismondo Eisenhower 2019-09-21 2939 0

Apple's new operating system iOS 13, as you know, was released on September 19. If you're wondering how the new OS performs on older phones like the iPhone 6S and SE, let's take a look at the results.

iOS 13<strong></strong>​ 

Running Apple’s latest software on the oldest supported hardware is often not a good idea. If you're wondering what it would be like to run iOS 13 on the oldest supported phones, the iPhone SE and iPhone 6S, we've prepared a brief review for you.

If you have one of these models and you are thinking of updating, there may be minor problems. You can reach the iOS 13 performance, which we evaluated comparatively item by item, at the bottom of our article.

Apple's A9 chip is still strong

To test the A9 chip, iOS 13 was installed on each device, logged in to the iCloud account, and the phones were expected to run in the background for a while. Then each application was opened 3 times in a row and results were obtained.

The results provide information about the daily use of the phone. If opening an application is slow with a newly installed software, it is probably the case for all operations of the device (such as loading pages or waiting for the keyboard to open).

In general, the iOS 13 performs slightly slower than the iOS 12 on these phones. Even at some points almost the same. You can examine this in detail in the following tables:
