The battery already lasts two days under my usage model, and the phone still has a five year warranty and OS support for another three years. I see that Fairphone are still selling some repair parts for FP2 and FP3, so I expect to be able to repair my phone through that whole time period unless something weird happens.
The FP5 looks like a nice upgrade, but I don't feel short-changed: I got a new phone when my old one was failing, and it's not absolutely top-of-the-line, and that's fine. Like you, I'll think harder about the next round of upgrades (maybe to the FP6, maybe the FP7), and I'd love it if Fairphone were to be clearer about their release schedule, but I understand that they don't want to Osborne themselves.

FP4 is also better at being €120 cheaper, and presumably €170 if they apply the same discount they did in April :) And I think it has dual SIM as well?
I seemed to have missed out on:
* +22% increased CPU GHz
* ~40% increased performance on GPU benchmarks at same power consumption
* Dual Sim
* +7% battery
* IP54 -> IP55 water resistance?
* And almost every other metric that I don't care much about e.g. Network, Display and Camera.
What's the F4 better at?
* Slightly smaller display 6.30 inch vs 6.46 inch
* Weight! I bet the F5 is heavier than F4 (225 grams) but I see no weight mentioned for F5.
* No change in Audio jacks, both seem to still have a single USB C connector.
I guess I'll just suck it up and wait for the Fairphone 6 or potentially Fairphone 7 in 5 years.
