Someone can check how much they got the power supply in your devices, in custom rom and if anyone in hyperos too pls share your charging watt/amp from the app.
I'm getting 24watt max from my original charger with using Portronics cable from Flipkart.
Take a look at this Portronics USB Type C Cable 6.5 A 1.2 m Konnect View 66W Type C Cable with LED Display on Flipkart
