Oneplus 15 isn't using the Sony LYTIA-T808 its the Sony IMX906 which is a big downgrade against the Oneplus 13 while the IQOO15 has the Sony IMX 921. Such a shame I really like the design and would have preferred the Oneplus 15 if it weren't for the big downgrade of the cameras against its predecessor. 😭

OnePlus 15 is better, because he is more faster and more powerful.

If u truly are wondering between the Chinese versions, then beware of the iQoo 15 screen delay and some quality of life issues which the OnePlus 15 does not have. Believe me, if you want, if not your choice.

The latency of the touchscreen is lower for iqoo, this is technically tested in games. 165 Hz doesn't mean less latency.
