is it worth to upgrade phone every year?

I had the flaw that each year a new phone came out I bought it.
I was very happy with it each time however due to the fact that I got it so soon everytime I always ended up waiting for a lot of bug fiixes and improvements etc.

Once when I got my new phone it took the creators about 6 months to have all their bugs and flaws sorted out, tbh back then it was a waste of my money. I'd recommend waiting atleast 6 months since the release date of the phone you are willing to get.

And now the only thing I REALLY need, and probably most of you all is a better battery ( increased storage )
