I got the Samsung s21 ultra yesterday and am having issuses already. The battery on the phone is set to superfast charging and I'm using a genuine charger and plug however its taking over 8 hours to fully charge and gets excessively hot when it is charging. I had seen other users saying you need a 25w charger and plug but I can't see a wattage on the plug and no chargers I'm looking at online specify a wattage. I found one but it's USB c at both ends . Is it not possible to get USB chargers anymore ??
I find when I set my N20 Ultra 5G to super fast charging this does then warm the phone up more because of the fact it's charging way faster than normal charging.
Where did you purchase the charger from ?
Is it definitely 100% a genuine Samsung charger ?

@User25 Looks like there may be an issue with that charger, it an official Samsung charger? Actually the wattage is displayed in several places online. You do need a 25 watt charger, the USB C cable will have been provided with the device. https://www.samsung.com/uk/mobile-accessories/wall-charger-super-fast-charging-25w-ep-ta800xbeggb/
