How long you planning on keeping the iPhone 17?

Just got my iPhone 17 last Monday. Coming from a 2017 IPhone X I’ve been holding on to that phone for almost 9 years. Never felt a need to upgrade at all. Almost upgraded when iPhone 14 pro came out but glad I hold out. Now iPhone 17 is a huge upgrade for me. It got everything I needed. Fast charging 0-50 in 20 minutes. Big screen. Big battery. 120 Pro motion display and always on display. This phone is almost perfect. I’m trying to see if I could hold on to this phone for another 8 years? I feel like there won’t be that much difference in future phones except maybe slightly bigger battery and new folded design. But I don’t care about that. iPhone 17 is a future proof phone for a very long time.
