Galaxy S26 Ultra Won’t Charge? 11 Fixes to Try First

Use an original Samsung charger first, then a known-good backup charger and cable. Plug directly into a wall outlet.

Force reboot while charging (Volume Down + Power), then inspect and clean the USB-C port.

If moisture is detected, stop charging until the port is fully dry. Also cool the phone if it is warm before retrying.

Install software updates and confirm fast charging settings are enabled.
