Updating to iOS 15 doesn't slow down older iPhones

Smartphone users often stop installing firmware updates over time because they fear that their gadget will stop working fast enough. But a comparison published on YouTube channel iAppleBytes comparing the performance of older smartphones on iOS 15 and iOS 14.8 shows that there is no noticeable slowdown: the maximum deterioration is only 2%.

Although the firmware used in the test was Release Candidate, in the case of iOS 15 it did not have significant differences from the final release, so the results can be considered true for the stable build. Here is a performance comparison (multi-core Geekbench test was used):

iOS 15 iOS 13 iOS 12.4.1
iPhone SE (2016) 2:53 3:08 3:05
iPhone 6S 2:45 3:21 3:24
iPhone 7 3:43 3:14 3:06
iPhone 8 3:27 3:19 3:22
iPhone XR 5:10 5:40*
iPhone 11 5:28 5:25*

And these are the results of the Geekbench battery life stress test, which determines how long smartphones will last under heavy load. Only the iPhone 6S showed a noticeable deterioration, while the iPhone 7, on the contrary, showed a significant increase in battery life.

iOS 15 iOS 14.8 iOS 13.7
iPhone SE (2016) 1 041 1 042 1 042
iPhone 6S 1 039 1 039 1 042
iPhone 7 1 393 1 407 1 403
iPhone 8 2 405 2 271 2 071
iPhone XR 2 504 2 510 2 556
iPhone 11 3 245 3 289

Given that each update brings not only new features, but also important security patches, the update to iOS 15 is worth considering even for owners of older devices - especially considering that the performance and autonomy of this almost does not suffer, and in some cases even improve.
