I understand 'worst sales' but 'worst performance' doesn't really fit. It's in my opinion this is a fantastic performance on the market. With right to repair, longer software support, some models with replaceable batteries, we can use the phones longer and make the industry more sustainable and consumer friendly. For the last years already, the model feature upgrades were marginal and it's fine that way.
In the future, I'd hope for further technical and regulatory development in that direction, resulting in further reduced annual sales numbers.
When the whole western society has been force fed that "we must consume else our economy will collapse", not continously outselling (and throwing away barely year old work) is bad, this is the result.
