I have the galaxy s21 ultra and have been using my ep-ta800 25 watt charger from my last phone (note 10 plus) and get super fast charging. I also decided to get the ep-ta845 45 watt charger assuming it would be even faster as the amps seem to be higher in the specs. But they charge at the exact same rate. Shouldn't there be a difference?

Thanks!

No, working as designed.  The S21 is not compatible with the 45w charger which means that the charging circuitry in the phone is limiting it to 25w.

It is 25W max as stated before but if you look at tests on the difference between the 2 you'll find that the amount of time it saves is barely even noticeable. Like maybe 10 minutes over a full charge

I believe it was just using the different chargers and timing how long it took to charge a certain percentage. I believe the article was on XDA but I'll look for it in a bit.

@aml15243 the max charging rate for the S21 line is capped at 25watts.

just curious, was the the note 10 plus capped at 25 or could have done 45? I remember almost buying the 45 watt charger when I first got that phone after reading up on it but just never did. luckily I got a great deal and have a fast charger for work, but it would seem strange to me if the note 10± could charge at a faster speed than the ultra which has a bigger battery.
