Fast charging

Use normal charger even if your smartphone supports faster

I am using fast charging method since 2020. For me, no issues and till now battery is in a good condition. I use to charge my phone in morning and next day need to charge. It also depends on phone type n the battery quality being used.

Fast charging is meant for charging quickly on the run for 15-20 mins. If you have more time to keep the phone plugged in or overnight charging, disable fast charging. You can also setup routine like this.

Seriously you're considering Samsung's 15W, 25W & 45W as fast charging? When other brands have gone upto 240W😂😝

Main point is battery temperature, I do fast charging only we use AC or at night when ambient temperature is cool. If you change your mobile every year then no need to worry about fast charging.

15w is not first charging it's called as normal charging.
so don't be panic about 15w charging .And also45w to 50w is also not harmful but the battery drain faster than normal charging.

By the way when you charge a phone one time it complete one charging cycle. One battery can handle 300 to 500 charging cycle, after this your phone battery is automatically degrade either you use first charging or normal charging.

If you care about battery health then use it only when necessary,because heat affects the liion battery health.
