Maybe not much affect. Don't buy it because you have to buy both charger and cable which maybe cost more that 1600 combined. When you got someone who using samsung 25watt charger try that one before. Beacuse in my s20 fe 5g phone redmi 25 watt charger and my 15 watt charger works same.
You will save 20 mins or so on a full charge.. Samsung uses PPS in its chargers which isn't like Oppo or others Chinese companies charging tech. I have s 22 ultra my 25 watt charger broke and I was forced to buy a 45 watt one since 25 wasn't available nearby and Amazon wanted a week to deliver the charger.. From 25 to 45 watt I only save 10 mins on a complete charge. The only difference would be the first 50-60% charge would be faster post that it will be equivalent to 15-18 watt.
Instead of this I'll suggest go for a Stuffcool based GaAn charger, speed and cool. I have one for my wife's fruit company phone and it's a charm.
I posted a thread regarding the charging speeds of my Galaxy S20 FE 5G... You can head over to my profile & check that to know whether buying the 25W Super Fast Charger makes sense for you or not🙂
