My old iPhone 6+ is still holding strong, though it's been demoted to a wifi-only game device for my daughter - I probably would have held onto it instead of upgrading to the 7+ but the GPU was a little on the anemic side to handle the upped screen resolution. On that same note though, my iPhone 7+ has been buttery smooth and considering the obscene amount of horsepower it has under the hood I can easily see me using it for 2-4 years (I'm skipping upgrading my phone for the first time in 7 years).
