S21 vs Adaptive Charger

[MelDna]

Recently I have bought a galaxy s21 ultra and an adaptive charger. So in the first days it charged well but after fews days it take so long to charge, even saying that is charging of super fast, it stop at 88% for a long time. So I want to know if the problem is with the mobile phone or with the charger. Can you guys help me?

There is the charger

What do you mean it stopped at 88%, does it stop charging once it reaches that or it just gets slower?

[MelDna]

It gets very slower

Have you tried disabling and enabling the fast charge option? There's also the matter of the phone charging slower because it's too warm or hot. Another thing is it charges at its fastest for the first hour then slows down before getting 100%

Yes, I tried enabling and disabling the fast charging option. Right now it has the super fast charging option enabled. I don't know what might be happening, but when I use the same charger with another phone the same thing doesn't happen, it charges fast all the time.

Go to Support side app and under phone diagnostics test the cable charging. If you go there and it automatically starts testing things just go back and it will show the list of things to test, then look for cable charging and see what happens
