Are you the developer by any chance? If so, it would be helpful to state it.
If you feel this is unannounced self-promotion, yes, it is, and can be done better.

Also, for the "objective" comment, it meant to say "the original comment is still objective", not that you can be objective only by being a developer. Being a developer can obviously bias your opinion.
I was also surprised on how well it ran on my iPhone 11 before I replaced it with a 15 pro.
