BagingaG59, yes 👍 too much power charging any battery will dramatically decrease a battery's life. I never checked the output ratings for my Samsung Galaxy Note20 Ultra 's charger. My lovely 20 Ultra, if it's battery if completely depleted, it takes only an (+/-) hour and ten to reach 100%, and That is totally fine for me. My Note10+ as you may Or may not know, Samsung offered a 45 W changer. But, I couldn't see shoveling out Ulysses S. Grant.
