Are you having low volume for iPhone alerts such as texts as well the lock button noise? SomeWell, as others have said, and I agree, yearly upgrades are usually not worth it. I myself have got the 13 Pro Max 256 GB as an upgrade from my 7 Plus 8 - also 256 GB which I got back in February 2017. So yea this is really a huge bump for me in every category and really worth it. I am keeping my 7 Plus which is in really good shape except for the battery to give to a friend.
