Phones don't actually get slower, or, they shouldn't, if they are reasonably well maintained. A battery swap might be necessary to preserve battery life under load. A NAND might start going bad.
Apple just shipped iOS 27, which has support for 2019's iPhone 11. So we are around 7 years there. It's probably fine for many people's use!
For a task like openclaw or hermes, or even something more aggressively graphical & GUI, it's not hard to imagine an 8 year old phone doing fine.

Relative to ever rising hw requirements of apps they obviously get slower. That is why I personally buy new phones.
Have you ever owned an older phone or older computer in general? Whether hardware or software caused, they get slower.
Only if the software gets slower. My 2015 MacBook Air is slow with the latest supported macOS but runs Linux super snappy for the same tasks.
Unless the thermal paste goes bad and the fans get clogged and you get thermally throttled.
Battery swaps usually don't work very well, unfortunately.
