IPhone4s runs iOS 9 to experience video

Audio commentary

Apple officially unveiled iOS 9 at the WWDC2015 developer conference in the early morning of June 9. In addition to significantly reducing installation space requirements from 4.6GB to 1.3GB, iOS 9 also supports iPhone 4S S, but support is supported, which does not mean that iPhone 4S can run iOS 9 smoothly. According to the experience of netizens this afternoon, iPhone 4S is not as smooth as iOS 9, or even iOS 8.3.

If you are skeptical of the above news, you can take a look at the videos shot by foreign media and compare the performance of iPhone 4S under iOS 9, iOS 8.3 and iOS 7.1.2.

Comparison of iPhone4s between iOS 7.1.2 and iOS 9:

Comparison of iPhone4s on iOS 8.3 and iOS 9 systems:

From the video point of view, iPhone 4S can still maintain a certain degree of fluency under the iOS 7.1.2 system, but it is already stuck in iOS 8.3, so I can't bear to watch iOS 9 directly.

Of course, this is only the first preview of iOS 9. Even iPhone 6 does not run smoothly and may be saved in the future.
