My s20fe has been charging extremely slowly the past few days, it takes 30 minutes to charge 5%. When plugged in it shows fast charging(15w Samsung charger from the box). Nothing that i have done is working to solve this issue. HELP!
'Fast charging' is the slow charging option, you can change that in settings, just search settings for 'charging' , what you want to find and see if it's enabled is 'Super fast charging'.
On a side note, from all of my phones, S20Ultra charges it's battery the slowest, for example MiNote10 does not know anything but 'Quick charging' ,this makes it's 5200mA battery full in about 1hr or less.
