Hi, 
I tried charging the s21 ultra with the official Samsungs 25Watt TA800 charger and it takes 1hr 15/30 mins to charge from 30% to 100% even with both Fast charging and Super Fast Charging enabled in DeviceCare. Is it normal or is there any fault with the device?, I have have formatted the phone still it takes 1hr 15/30mins to full charge. Actually it should get fully charged under an hour like in just 40 to 50 minutes isn't it? Is there anyone facing the same issue? Is there any solution for this?

Hi Sebin,
Are you using the data cable that came along with the charger? The fast charging works only if the data cable supports that. Sometimes this may happen due to cable damage also. Try with a different cable.

I too used similar charger provided with S21 Ultra bundle offer, and it do takes more than 1hr to charge from said range.
But I noticed, if we put it on airplane mode, then it charges more rapidly and this I prefer a lot.

But how come both fast and superfast require same durations? I haven't used superfast charging.

Just Fast charging shows around 1hr 30mins as estimated time ....while the super fast shows like 40 to 50 mins estimated time to reach 100% but these don't finish at the estimated time
