I mean its not that crazy, I’m writing this on a moto Z2 play. It was released June 2017, not long till year 6 bit hope it goes longer. It’s perfectly usable, runs most apps fine, can even run TFT.
Phones haven’t changed that much recently, this model has a great screen, 4gb of ram(more than some laptops that are still being released!), and a decent chip. Only issue is the battery is sub 3000mah but I know of a few models from around the same time went up to 5000mah.
You do get better mileage running an OS like lineage and being degoogled since a lot of their tracking processes kill the battery and slows things down.
