My S21 Ultra is taking 1.5 hours to charge from 5-100% with the Samsung 25W super fast charger and the cable supplied with the S21 Ultra.
And I have fast charging and super fast charging enabled on my device.
All the user reviews & battery charging tests online show that the S21 Ultra takes roughly between 1 hour 9 minutes to 1 hour 15 minutes to do a full charge from 0-100% with the Samsung 25W Super fast charger.
Any idea what is going wrong here? Is it an issue with the phone, cable, or charger?

@SgtRepeat: When you connect your phone to your charger, does it say Super Fast Charging on screen, and provide an estimated time for it to reach 100%. If you power off the phone completely and connect to your charger, do you notice an improvement?

It does say Super Fast charging and provides 1 hour 6 minutes as the time for a full charge, but 30 minutes in and only around 35% is charged.
The estimated time at the 30 minute mark is around 50 minutes.
A full charge takes around 1 hour & 30 minutes.
I haven't tried powering off the phone and then charging it.

Great, then it's not a software issue on my phone.
Wanted to check if the charge time has been increased due to a software update. Samsung did it with the S20 Ultra where the charge time increased from 1 hour to 1 hour 20 minutes.

I have the same problem and now last about 2h20m to full charge, from 1% to 100%. I don't use it when charging. I have tried 3 different 25W chargers and also cables from Samsung and the problem persists.
I also did a factory reset and I still have the problem. I'm afraid that I have to look for a technical shop.
