I see many charging test in Youtube, the Galaxy Note 10+ only takes 1 hour and 5 minutes to charge from 0% to 100%, while my Note 10 takes more than 1 hour and 30 minutes to charge from 0% to 100%.
Keep in mine that the battery capacity of Note 10+ is 4300mAh, and 3500mAh for regular Note 10.
This charging test uses the 25W charger, Note 10+, 0% to 100% in 1 hour 6 minutes.
I just wanna know if I had a defective charger.
Have you checked if your fast cable charging is enabled?
You should also consider what apps and processes might be running on the phone, cellular vs Wi-Fi, screen brightness, and so on... Point being a phone that's used for tests is likely fairly clean and fresh out of the box, while you might have more things using power in the background, and that affects the charging speed.
I wouldn't worry about numbers. The included charger is fast. And there is an even faster option available. Personally I almost always use wireless charging anyway. It rocks.
