Ios 14 Work On 6s. IOS 14 updates the core experience of iPhone with redesigned widgets on the Home Screen a new way to automatically organize apps with the App Library and a compact design for phone calls and Siri. I would recommend against updating your iPhone 6S to the latest iOS.

Using an iPhone 6S in 2021. This year is the same -- Apple isnt excluding the iPhone 6S. If youre wondering if iOS 15 will work on an iPhone 6s heres what you need to know.
Performance is fine other stuff is not iOS 14 wont ruin older phones but a second-gen iPhone SE is a tempting upgrade.
When Apple revealed iOS 13 last year it announced the update would work with the iPhone 6S iPhone SE 2016 and newer models. Since iOS 14 is the latest firmware release for iPhone models 6s owners would also. I dont think iPhone 5s will support iOS 13 so Id say currently the current. I have the iOS 14 beta running on my iPhone 6s and it runs great.
