Damn, really underwhelming from my Xiaomi 15.
My Oneplus 3 from 2017 feels just as snappy, and the interface is far more intuitive and you can easily customize everything.

Whether it's camera, or sound, the improvement over these 8 years are negligible.

I guess the only objective improvements come from

>chipset, only ever really relevant when gaming
>faster charging speeds, but probably at the price of faster degrading battery

I run the OP3 rooted with ViperFX, it sounds better and gets louder with inears.
Why do some people change their phones every 2 years or so?
