UPDATE: Super Fast Charging 2.0 Not Working

[campusrunner]

Update: I am now running the following software version, but I am still unable to get Super Fast Charging 2.0 on my s25 Ultra.

Software version: S938U1UEU1AYB3 /

S938U10YM1AYB3 / S938U1UEU1AYB3

Security patch level: February 1, 2025

Samsung EP-T6530NBEGUS charger connected to S25 Ultra with a 5A Samsung cable only triggers Super Fast Charging, not Super Fast Charging 2.0.

I've seen multiple YouTube videos showing 2.0 on the lock screen. What am I doing wrong?

Every time I used my charger, super fast charging 2.0 popped up it would charge my phone extremely fast now for some reason the same charger same everything all it says is charger connected now it wants to take 3 hours to charge. I've tried multiple chargers went and bought a new charger new cable everything still nothing works now

Hello, 

Did you found any solution? 

I used anker 45w charger & samsung original s25 ultra cable, it shows only super fast charging not "super fast charging 2.0" 

Please reply me if possible. 

Thanks

since i have never done this before and just got a 45 watts when you plug into phone and it saids super fast charger 2.0 it then goes straight to charging and that's it right am little confused it doesn't go back and forth between super fast charge 2.0 and charging  it just goes right into charging right?

That's it, once it says super fast charging 2.0 you're good to just let it charge

ok the brand name easdmn 45 watts 6 feet combo cable came into today along with car charger with another cable<-haven't used yet came in today and i just try it out and didn't know 

i have yet to try out s25 plus cable yet i'm getting  tomorrow

everybody told me about despite it doesn't say compatible on website and email i bought me 45 watt anker wall  charge for backup so i can used it for travel 

instead having to always removed the current 45 watts from easdmn today

Samsung sells 2 types of cables.
1st one is the one that comes free in the box with the phone. They are thin and don't support super fast charging (even when using a 45-watt adapter).
2nd type of cable is thicker, which support super fast charging (they come with the charger in the box if you buy one).
I also heard Samsung starts including the thick cable in the s25 series.

S25+ and S25 Ultra now support Super Fast Charging 2.0 using 45W Brick and either 3A or 5A cables

[Dinop43]

To get true superfast charging you need the 45w block and at least 100w/5amp cable like the op said the ones that come with device are all 3amp which is only capable of 25w chargingvand still says superfast charging
