Charge using a USB-C cable:

Connect the USB cable to a Samsung-approved USB power adapter.
Plug the cable into the phone’s multipurpose jack (USB-C port).
After fully charging, unplug the charger to conserve energy and prevent overcharging.

Always use a Samsung-approved charger and USB Type-C cable. Avoid Micro USB cables, which may damage your device.

Charge wirelessly:

Place the center of the phone’s back on the center of a compatible wireless charger.
Wait for the charging indicator or notification panel to confirm the connection.
Once fully charged, remove the device from the charger.

Remove cases or metal accessories to ensure stable wireless charging. Use Samsung-approved wireless chargers for best results.

Go to Settings > Battery > Wireless power sharing, then toggle it on.
Place the other device (e.g., Galaxy Buds, Watch, or phone) back-to-back with your Galaxy phone.
When finished, remove the device to stop charging.

Only compatible devices can be charged. Avoid using headphones during power sharing and ensure devices stay aligned.
