My indestructible 6 has had a few battery and screen replacements over the years (and a home button), but is still my daily phone even now in 2026. I call it my dumb smartphone. I can make calls, send messages, play music, store photos/videos, etc, but banking and any form of social media is a thing of the past for this thing – I'm not worried. I have an android phone that stays in my office for all that good stuff, and just take my old 6 with me wherever I go. There is freedom in limitation.
