25W charger came with the box for note 20 ultra not fast charging. It only charge normal slow cable charging & super fast charging. Adaptive fast charging (normal fast charge) won't work even it enabled in settings. But when I connected to my old Adaptive charger, fast charging is showing. Is there anyone who noticed this? I think 25W charger only supports slow cable charging & super fast charging.
Ok so this is what has happened. They've removed this feature from note 20 ultra. When i got the phone it was on one ui 3.1 and the adaptive fast charge feature worked.
I tested it today because u were asking about it, and now it only shows cable charging, even with super fast charge off and fast charge on.
They have removed this in one ui 4.
But i noticed a small change, when u switch off everything and leave it on cable charging, the time it takes is longer than when u enable fast charging. Even though fast charge is enabled, it still says cable charging, but the time taken is lesser than actual cable charging.
I hope this solves ur issue. Its something that they changed in One ui 4.
