20% faster
The 25W charger can charge the phone to 33% in 30 minutes, while the 15W charger only charges to 26%; However, at 45 minutes, the difference is very small: the 25W charger charges 51%, and the 15W charger charges 49%.
However, after an hour of charging, the 25W charger once again took the lead, charging the device to 67%, while the 15W charger only charged it to 60%. Although the Galaxy S10 can also charge to 67% after an hour of charging using a 15W charger, it is a 4,100 mAh battery. So you can imagine how fast a Samsung Galaxy phone, equipped with the Super Fast charging standard, will be using a 25W charger.
