How can I upgrade my iPhone 6s to iOS 15?

If you have an iPhone 6s, go to Settings ➜ General ➜ Software Update.

If you have an iPhone 6 (no s), then it cannot update beyond iOS 12.5.6. It lacks the hardware, RAM and CPU to run anything newer.

Are you sure you have an iphone 6s and not just a 6 without the S

Well, quite frankly, I’m not sure if a success will be able to sometimes as the phone gets older the latest updates will not work. I know that my son had a actually it was an iPhone 6 and I bought him an Apple Watch but he could not download the app he needed in order to pair the two

mine don’t have software update. I can’t find it
