    Welcome to iMore! Apple is no longer signing any version of 7.xx or 8.xx so you can't upgrade to any of them. I would go with 9.1.

    I use 5s too and I just upgraded to iOS 9.1 yesterday. So far it works great, smooth and better battery life than 9.0.

    Many thank for answer….

    To get most out of my iPhone 5S I should stay with iOS 7 ? I mean to avoid it getting slow down, I have read that somewhere that other iOS than the iPhone is made for don't make it exactly new again but slow down the performance?

    I can understand that I have to update all apps even that takes memory and might slow down my iPhone but other big iOS will definitely slow down the iOS and or performance?

    I don't know ??but asking because I never had iPhone before.

    I don't think you're really going to see a noticeable negative impact in upgrading to 9.1. Apple is still selling the 5s and I'm sure it's shipping with iOS 9.xx.
