Samsung has been pushing its fast charging speeds lately – getting from 15W on the Galaxy S10 line to 25W and 45W on the Galaxy Note10 and Note10 , respectively.
Now the Galaxy S20 Ultra has retained the 45W charging power but is apparently able to use it better. Reportedly, the Galaxy S20 Ultra’s built-in 5,000mAh battery goes from 0% to 100% in just 58min with the optional 45W charger.
That’s quite the impressive feat, given that the Galaxy Note10 ‘ 4,300mAh battery takes a few minutes over an hour with a 25W charger and a few under an hour with a 45W charger.
Batteries can use a higher wattage when they are low on charge and reduce the charging rate as they fill up. The Galaxy S20 Ultra likely maintains the higher charging rates much longer than the Galaxy Note10 allowing it to fill its much bigger battery in the same time.
