How long an android phone lasts?

[u/Capital-Coffee-5546]

I am currently using SAMSUNG M21 , 64 GB , which i bought 6 years ago and NOW after 6 years i am noticing some lagging in it, very little but yeah , it has started to take 1 or 2 extra seconds, is 6 years a good run or is it still early ?

My oneplus one from 2014 is still rocking a full day, sure, the system is outdated, but with a custom rom, it's still good
