If you want to use some of the new iOS 9 features, you will need to upgrade to this new update. The overall experience with iOS 9 is positive, but on an older device there are always concerns.

In this case, if you upgrade to iOS 9 you can expect added features, possibly better battery life and fixes for some iOS 8 issues. Don’t expect a completely new experience on your iPhone 4s, as it is still an old device, and a surprise that it is getting iOS 9.

For the time being you can install the iPhone 4s iOS 9 update and still downgrade to iOS 8.4.1 if you don’t like it.
