As you know that Samsung A32 has a 15W charger and fulls charges after 2hour 10-14 minutes when you don't turn the phone off (power menu > Power Off. - not turning it off will take 7% of the charging time will increase to get full at %100) ..
So as summary.. I tried to turn my phone off/shutdown from 2% to 10:40pm and after some few hours the battery got full in 2 hours 8 minutes.
While keeping your phone on like just pressing the power button once to off the screen and leave it.. it will take 2 hours 14 minutes.., (0% to 100%)
Note: I used 15W Genuine Samsung Adapter.. and the original cable.
So quite that I would possibly like to buy a 45W charger and see how long does it takes...
For my opinion... The written output on the battery must be only
9V 2A. = 15W
20.00V 2.25A = 45W
My guess is that the phone would expect a overheat on the battery while charging or what. And the charging time wouldn't reduce to 1 hour 56 minutes estimated.
Here's some proof of the charging.
From 10:43PM is my time when I plugged the charger after plugging the screen woke up and shows 2%.
And after some time of 1:03AM it got full.
I usually left some because it takes longer to get atleast 1% at 0% battery like 6 minutes.
