Video compares iOS 9.1 beta with iOS 9.0 on the Apple iPhone 4s and Apple iPhone 5
As it turns out, Apple is currently pushing out the iOS 9.1 beta to those testing the new build. So of course, those with the iPhone 4s and iPhone 5 would want to know whether Apple was able to improve the performance for those rockin' the older models. Many have reported a major improvement for those two greybeards after installing the beta. To see if this is really so, the iPhone 4s and the iPhone 5 were put through the paces while running both iOS 9 and the beta version of iOS 9.1. The test was recorded on video
Two iPhone 4s units were tested side-by-side. The one on the left was running iOS 9 while the one on the right had the iOS 9.1 beta installed. The pair of iPhone 5 models also had the one with iOS 9 on the left and the unit running the iOS 9.1 beta on the right. The bottom line? The animation on the pull-down notification shade was a bit faster on iOS 9.1. Other animation was smoother on the newer build of iOS.
Overall though, it really was a toss-up which iOS build was faster on the iPhone 4s, while iOS 9.1 was faster on the iPhone 5 by a slim majority. Regardless, the difference in almost every case was a fraction of a second. Looking at the video, it really doesn't seem that there is much of a change in performance between iOS 9 and the iOS 9.1 beta on those two specific iPhone models.
