ELI5: Why do mobile phones, unlike a laptop, still operate smoothly despite not being shutdown for days/weeks?

I know if I leave my MacBook running all day long for about 2 days applications will start opening slower, more freezes, etc. But my phone hasn't been shutdown for days (maybe even a week now) but still runs fine.

Nothing in theory means your laptop or other generic computing device need to be restarted. In practice it tends to be bad programming causing things like memory leaks or issues that accumulate over time.

Plenty of servers and datacentre computers measure their uptime in years.
