I’m an S25 Ultra user. Am I the only one experiencing this, or are there others too? After I updated my system from UI7 to UI8, my Super Fast Charging suddenly stopped working. I’ve already tried all possible troubleshooting steps, but it still won’t work. Samsung, please fix this.

What's the brand of your power brick and wire? I am using Anker 45w for my S25U and it's still showing the #SuperFastCharging2.0 but I notice slight difference in the charging speed.

Im using the proper Samsung charger and mine isn't the same since updating...it'll show fast charging for a second or 2 and then go to the slow charge..over 2 hours for a full charge is not good!! Only started since the new ui update
