but the same charger does super fast charging on another phone but does not do super fast charging on my phone. This means that the charger is original, and the charger is fine.But charging speed is very slow

I did my last software update in February... my android version is 14 and oneUi 6.1 but how we jump from android 14 to direct to 16 and oneUi 6.1 to 8 ???

The battery drains very quickly, and my phone supports super fast charging, but the charging speed is very slow, and super fast charging is not written on the screen.

When??

I know....Next version of oneUI 6 ??
