Fast charging

If its producing more heat then its bad for battery.

Fast charging usually does not have much impact as all the process is controlled by the chip on the phone. Coming to samsung, the max watts is 45, this should not cause any long term issues. However, usage of very high watt like 100, 160 would cause battery to drain faster overtime. Now a days we are so busy and need faster charging to do other works. So enabling is a good option. Usual cases a phone does not last longer than 4-5 yrs and we tend to change evrn before, so you should be fine with fast charging. Hope this helps.

I think it's depends on charging and device support that ho much watt is supported by device if charging is genuine then ok .😊

Using either the original or a compatible charger won't cause any issues.

I turned it off on my 23 ultra and the battery battery backup got higher but it takes more time to charge n I charge it around 5.30am everyday so I have no issues at all. I recommend if u have time to charge for long time then turn it off n if u don't have enough time it's OK to have it turned on

Fast charging= more heat..

So in summer or hot environment, just Avoid fast charging..

+ Don't use phone when you are using fast charging....

+ After the phone is charged quickly.. don't use it quickly..
Wait for 15 minutes before use.

In a cool environments, airconditioner area, you can use fast charging..
