In Samsung S20 fe 5g battery percentage 46 percentage when I charge it comes for 90 percentage takes some time but in my vivo mobile ordinary charger same time battery percentage 46 I charge it fastly 100 percentage
Its there to protect battery health because above 90 the battery voltage increases so the charging circut just slows the charging to protect battery from heat.eg.iphone charges slowly above 80 to prolong its battery health.
