I still use an iPhone 4s but to get the apps I want to get they want me to upgrade to iOS11. Will my 4s choke on the new OS? Perform horribly? Can I go back - I am currently running 9.3?
iPhone 4S
No.
Your iPhone 4S is too old and cannot be upgraded past iOS 9.3.5.
The hardware is not powerful enough to handle running newer iOS versions.
Sorry.
The 4S can not be upgraded beyond 9.3.5.
Can an iPhone 4S run iOS11?
