I know this an obvious question but, after 4 years with a phone is it supposed to lag?

I have a galaxy a22. I have this since 2021 (the year it launched) and it's lagging hard nowdays.

I know a lot of ppl are already used to this, saying something like "oc its gonna lag" but I really think this is really weird.

I have a pc since 2016 and use it all the time, despite this its performance hasn't really changed one bit

Meanwhile my 2021 phone is lagging twice as hard if not more than when I originally bought it

Is this lag really normal?
