My S24 Ultra not Superfast Charging 2.0 anymore!

[aklos]

It started 4 days..out of sudden, while charging my s24 ultra with 45watt brick charger and samsung original type c to c cable, it stopped charging fast. I tried to change the adapter, charge at different plug still the same. 

Then, I reset the battery log, clearch cache and clear setting. Still the same. 

once i plugged in the superfast charger, it will pop out the turquoise ring, indicating superfast charging 2.0, and it will shows estimated time, example 45 minutes left. After 3 minutes, the battery percentage didn't increase, and charging time changed to 1 hour 30 minutes. And i started to charge slowly after that. What happened?

I've searched for this problem in another forum, there are many samsung user experiencing this..any solution?

i never wanted to use fast charging, actually i only have 25W galaxy phone and i simply turn off fast charging since day one i bought the phone, i have been like this about 7 months and i don't see any drop from charging speed from my 25W Samsung brick, from 30% to 80% always take about 1 hour and few minutes which is ok for me (ik it's not speedy but if i am not in hurry i won't turn on fast charging), and yes i use maximum protection for my phone

so i think my "weird" decision was right to keep my brick and my phone battery last longer, because i think either your brick broken (which is still possible) or a component inside your phone can also broken (rare occasion but sure still can happen), i know you may think, "impossible it was just 4 days! how can it break so soon?" but any electronics can break easily, especially that 45W brick, so my solution try with another samsung 45W brick, you should able to get Super Fast Charging 2.0 with a new one, assuming your phone component acting correctly

or become like me, turn off both fast charging and super fast charging, your choice

I really need superfast charging and im gonna use it since it's a feature. Im always in hurry. My brick is not broken, i have another galaxy phone. And it works fine on that phone

45 watt buy original one .

[aklos]

It's original. No issues

[Amir_13]

You phone charging board has problem go to service center with charger .

I take it that when you said you tried using different adapter but problem still persist, you are using the same USB C cable.
Maybe you can try using another USB C cable instead. It's a known issue that if the cable is faulty, PD fast charging won't work.
All the best.

Actually, i used different cable too. It doesn't work. My s22 ultra is fine with the ultra fast charging. just the problem with s24 ultra
