S24 ultra not retaining Super fast charging 2.0

[Devilbawa]

So i just bought s24 ultra yesterday and i also bought the 45w charger with 5a cable model name tp4511. I plug in the charger and it shows SFC 2.0 only for few moments and says like 22 minutes to full charge but then it changes the status to normal charging and time remaining gets doubled. I have no idea how to fix this.

It's normal for charging to change from "Superfast Charging 2.0" to just the timer and charging % after a couple seconds. If, however your timer is doubled or that the charging information changes to state just a regular charging state (this is not normal functionality), then there may be an issue.

Exactly.. I also bought it recently. I am facing same charging issue. I updated to OneUi 7 just after unpacking. 

Don't understand if its One Ui 7 bug or what. This is frustrating.

I tested my Samsung 45W adapter and cable with multiple S24 Ultra devices, including those at the Samsung service center. All of them show only "Super Fast Charging", not "Super Fast Charging 2.0", even though the same setup(same adapter and cable) shows "Super Fast Charging 2.0" on the S25 Ultra.

The person in the center mentioned that only certain older chargers (possibly bundled ones or the one with adapter and cable) might display the "2.0" label, but couldn't clearly explain the reason. It’s unclear whether this is a UI limitation, a firmware restriction, or a genuine difference in charging behavior or is there any difference in new adapter and older version adapter if changed.

A clearer explanation from Samsung is needed to confirm whether S24 Ultra actually supports Super Fast Charging 2.0 in full or if the label is intentionally suppressed despite using the correct accessories.
