Wireless charging S23 Ultra

[Bright Angel]

My new S23 ultra gets quite warm whilst wireless charging but not using the usb. Is this OK ?

If using fast wireless charging, then yes the phone does get warm.

Hello @Bright Angel 

You will experience some warming up of the phone when charging however it should not be that hot that you cannot handle the phone.

Maybe it's the Wireless Charging option your using !

Mine is a Samsung version that also has a built in fan.

Sometimes if a case is left on while charging this can hinder heat dissipation.

My phone heats up a lot when fast wireless charging in the car especially if it's a warm day and it gets quite hot. If it gets too hot the charger or the phone will usually stop charging whilst the phone cools down. Other than that I don't use wireless charging as I only use the in car charger to stop battery dying whilst using the sat nav. You can get round this by plugging in and charging with a usb c but wireless is more convenient in the car. The issue has been the same for various phones I've used so not specific to the S23. I think by its nature wireless charging will create more heat than a wired connection so fast charging will not doubt amplify it. I hope this helps
