Can I install iOS 9 on iPhone 4S? I have received this question quite often in the last few hours from various users who own this Apple smartphone and the answer is yes, you can install iOS 9 on iPhone 4S.
Company Apple Lossless Audio CODEC (ALAC), surprised a lot of people by keeping it iPhone 4S compatibility with iOS 9, and this because we are talking about a 4-year-old smartphone whose hardware is not quite as powerful as many would imagine.
The iPhone 4S had numerous problems running iOS 8 released by the Apple company and in the case of iOS 9 things are not very different, the performances are not better, although the Apple company promised that the iPhone 4S will run iOS 9 without the slightest problem.
iOS 9 on iPhone 4S
In the video clip above you have done a performance test that will tell you how well iOS 9 works on the iPhone 4S at the moment, the results not being as good as presented by the Apple company at the time of the announcement of iOS 9 in June of this year.
The reality is that the iPhone 4S is old and has components unable to run the iOS 9 operating system without problems, and if you own such a product, you must be aware of the fact that you will not have high performance on it.
iOS 9 can be installed without problems on the iPhone 4S, but unfortunately you will only experience more lag in using all the applications and functions that the Apple company makes available to us, and this result is as normal as possible.
My recommendation for those who have an iPhone 4S is to update to iOS 9 only if they are 100% sure that they will be able to tolerate the lag in using terminal functions, otherwise the installation can be avoided until the upgrade to a newer iPhone .
