Well yeah, how else could they sell you a new phone every year or two if the one component that degrades over time could be easily replaced?
It was shocking how well my phone works after putting lineage OS on it, my pixel 3 runs better then my sisters pixel 7 now. If it was not for the battery I would likely be able to run on this hardware for a much longer time. And even with it all sealed up it will be cheaper and better for me to buy more "old" phones when the battery goes out then replace the battery.
~~$442~~ Wait, new us price (since its built in china, for a Japanese company) is $1000
