Fast charging is not supported

[Qewal]

My galaxy s24 ultra is not supporting fast charging even 25w charger. Its auto disconnect. Only normal charging with same charger and its take time too long. What is the main problem any idea? Any solutions?

S24 ultra support 45w fast charging.
If you are using 25w it will charge normal.
For fast charging you need 45w.
If still you are facing the same issue visit Samsung customer care.

Yes i have 45w charger but not worked so i tried to charge with 25w too but that is also not worked. Only normal is supported.

I can recommend to you:
1. Use a non-metal toothpick or compressed air to gently clear the USB-C port. Even a tiny bit of pocket lint can prevent the fast-charge pins from seating correctly.
2. Go to Settings > Battery > Charging settings and toggle Fast charging OFF and then back ON.
3. Borrow an official Samsung 5A USB-C to USB-C cable. Most "auto-disconnect" issues are caused by the cable being unable to handle the 9V/2.77A required for 25W charging.
4. Turn off the phone, connect it to a computer via USB, hold Volume Up + Power until the recovery menu appears, and select Wipe Cache Partition. This fixes software glitches affecting the charging controller.

Thank you for sharing your concern regarding the charging behavior of your Galaxy S24 Ultra.
We understand that the device is not supporting fast charging and is disconnecting automatically. Kindly note that the Galaxy S24 Ultra supports Super Fast Charging (up to 45W), and this feature depends on using compatible Samsung charger and cable, as well as correct device settings.

To resolve the issue, please follow the below steps:

1. Ensure that you are using an original Samsung 45W charger along with a 5A USB-C to USB-C cable that supports Super Fast Charging
2. Go to Settings > Battery > Charging settings, and make sure that Fast charging and Super fast charging options are enabled
3. Check the charging port for any dust or debris and clean it carefully using a soft brush or compressed air
4. Try using another original Samsung cable and adapter to rule out any accessory-related issue
5. Restart your device and test charging again
6. Update your device software to the latest available version

If the issue still persists and the device continues to disconnect while charging, this may indicate a hardware-related issue. We recommend visiting the nearest service center for a full inspection through the following link:
