Important Note: The information on this page is for Hong Kong products only. Models, sequences or settings will vary depending on location and/or where the product had been purchased. To be redirected to your local support page please click here.
If your Galaxy phone does not charge or charges more slowly than usual, the issue may be related to the battery, charging cable, power adapter, wireless charger, charging port, moisture detection, or device temperature. Review the guidance below to identify the cause and restore normal charging.
Note: Continued charging issues or significantly reduced battery usage time may indicate a hardware problem. Visit a Samsung service centre for inspection if the issue persists.
Check the estimated charging time
You can view the estimated remaining time until the battery is fully charged.
Step 1. Tap Settings.
Step 2. Select Battery.
Step 3. Check the remaining charging time.
Step 4. Check the remaining charging time from the notification panel.
Note:
- The estimated charging time may vary depending on device condition and charging environment.
- The charging time may not appear if the device temperature is too high or too low.
Stop using the phone during charging
Using high performance apps such as games, video streaming, or browsing while charging can increase device temperature and slow down charging.
Charge your device at a proper temperature
Charging may be limited if the device or surrounding environment is too hot or too cold. It is recommended to charge the device at room temperature for stable charging.
If the device temperature becomes too high, charging may stop temporarily or charging speed may decrease. Wait for the device to cool down before charging again.
Reboot your device
If your phone still has power remaining, try a soft reboot. This will allow the device to reset its temporary memory and will help you determine if the problem is software related. To perform the reboot press and hold the Power and Volume Down keys until the device restarts.
Note: The key combinations may differ slightly depending on the model of your device.
Using non-genuine or damaged charging accessories may cause slow charging, charging interruptions, or charging failure.
Use Samsung genuine chargers and cables
Low quality or non-approved chargers and cables may cause slow charging or intermittent disconnection.
Even if chargers and cables look similar, charging quality and performance may vary.
- For optimised charging performance and device safety, Samsung recommends using genuine Samsung chargers and charging cables designed for your Galaxy device.
Note: Using non-genuine accessories may damage the device or cause charging issues.
Check the charger connection
If the charger is not connected properly, the device may not charge normally.
- Disconnect the charger from the Galaxy device and reconnect the charging cable securely to the charging port.
Check for charger or cable damage
A damaged charger or charging cable may cause slow charging, heat generation or prevent normal charging.
Long-used cables should be checked or replaced if necessary.
- Try charging the device using another genuine Samsung charger and cable.
- If charging still does not work, visit a Samsung service centre for hardware inspection.
Note: Damage caused by user misuse or chargers outside the warranty period may require purchasing a new charger.
Dust or foreign material inside the charging port is one of the most common causes of charging issues. If dust, lint, or debris builds up inside the charging port, the charging cable may not connect properly to the charging terminals.
When using wireless charging, make sure there are no foreign objects between the device and the charging pad, as it may slow down charging.
Step 1. Turn off the Galaxy device > Use a flashlight to inspect the charging port.
Step 2. If dust or debris is visible, gently blow air into the charging port to remove it.
If your Galaxy device supports fast charging, make sure fast charging is enabled in Settings.
Step 1. Open Settings > Tap Battery.
Step 2. Tap Charging settings.
Step 3. Turn on Fast charging and Fast wireless charging.
Note:
- Starting from the Galaxy S23 series, Fast charging and Super fast charging settings are combined into one Fast charging setting.
- Fast charging may not work when connected to a PC or standard USB device.
- Fast charging is not supported when using a normal charger.
- For wireless fast charging, ensure the charger supports fast charging.
If Battery protection is enabled, charging may stop early or the maximum charging level may be limited depending on the selected option.
Step 1. Open Settings > Tap Battery.
Step 2. Tap Battery protection.
Step 3. Select a different option or turn off Battery protection.
If moisture is detected in the charging port, charging may stop to help protect the device from damage.
Note: Even on water-resistant Galaxy devices, the charging port must be completely dry before charging.
Step 1. Check for moisture detection notifications.
Step 2. Shake the device gently to remove moisture from the charging port > Wipe the device with a soft, clean cloth.
Step 3. Dry the device in a well-ventilated area using cool air.
