The 12 is currently tipped to launch with OnePlus' most exciting top-end smartphone upgrades of the last few years. However, its charging tech is not one of them, according to a new leak. It suggests that the upcoming Android flagship might come with a new power brick - however, it will have the same specs as that of its predecessor the 11. https://www.notebookcheck.net/OnePlus-12-tipped-to-launch-as-2024-flagship-Android-smartphone-with-2023-charging-specs.765239.0.html
That "2023" charging is still way, WAY faster than what Samsung, Apple, and Google can give in 2023. Don't expect to see them giving 80W, let alone 100W wired charging any time soon.
