How To Fix A Samsung Galaxy Not Charging (2026 Guide)

Your Samsung Galaxy will not charge, charges only in bursts, or shows a charging icon while the battery percentage stays put.

Most cases come down to the cable, a dirty port, moisture, or a charging setting, and all of those can be checked at home.

Work through the steps below in order, which takes about 20 minutes before you need a service center.

Which fix matches your symptom?

What you see	Likely cause	Go to
Nothing happens when you plug in	Cable, adapter, or dirty port	Steps 1 and 2
Water drop icon or moisture warning	Moisture in the USB port	Step 3
Charges slowly	Charger rating or fast charging off	Step 5
Stops at a set percentage	Battery protection	Step 6
Charging pauses and phone feels hot	Overheating	Step 7
Does not charge from a computer	PC port, hub, or driver	Step 4
Fails even in safe mode	Hardware	Steps 10 and 11

Menu names can differ slightly by model and One UI version, and the steps follow Samsung’s own charging guides.

Step 1: Check the charger and cable

Samsung recommends compatible Samsung chargers and cables, because lookalikes vary in quality.

1. Unplug the cable and plug it back in firmly at the phone’s port.
2. Try a second compatible charger and cable.
3. Test the wall outlet with another device.

If a different charger and cable fix it, the original accessory was the problem.

Step 2: Clean the charging port

Lint packs into the port over time and can stop the plug from seating.

1. Power the phone off.
2. Shine a flashlight into the port.
3. Remove visible dust or debris carefully, without metal objects or liquids.

Never poke the pins with metal, because bent or shorted pins turn a cleaning job into a repair.

Step 3: What if the phone says moisture was detected?

A water drop icon means the phone has detected moisture in the port, and Samsung says charging stays disabled until it evaporates.

Do	Do not
Unplug the charger right away	Keep trying to charge while the warning shows
Wipe the port gently with a dry cloth	Use a hair dryer, oven, or other heat source
Shake the phone gently with the port facing down	Use liquids or metal tools in the port
Air-dry it in a ventilated spot, or with a fan	Plug in before the port is fully dry

If the icon stays, power the phone off and leave it somewhere cool and dry for at least 24 hours.

If it still will not charge after that, contact Samsung, since technicians can inspect the moisture sensor and charging parts.

Step 4: Why will it not charge from my computer?

A PC port supplies less power than a wall adapter, and fast charging does not work over it.

• Keep the PC awake: do not let it sleep while connected.
• Skip hubs and adapters: Samsung says they may reduce power output.
• Try a USB 3.0 port: it is often blue and may charge faster.
• Update the driver: in Device Manager, expand Portable Devices, right-click your phone, then choose Update driver.

Restart both the phone and the PC, then reconnect.

Step 5: Turn on fast charging and match the charger

Go to Settings > Battery > Charging settings and turn on Fast charging and Fast wireless charging.

On the Galaxy S23 series and later, Samsung combines fast and super fast charging into one setting.

Charging speed	Adapter	Cable
15W fast charging	15W USB-A	3A cable is enough
25W super fast charging	25W USB-C	5A USB-C cable gives best results
45W to 60W super fast charging 2.0	45W or 60W USB-C	5A USB-C cable

Samsung is blunt that a regular charger cannot fast charge the phone.

Step 6: Why does charging stop before 100%?

Open Settings > Battery > Battery protection and pick a different option, or turn it off.

With protection on, Samsung says charging may stop early or cap the maximum charge level.

Step 7: Let a hot phone cool down

If the phone overheats, charging may pause or slow.

Unplug it, take off the case, and let it cool before you charge again.

Step 8: Restart the phone

Hold the Side key and Volume down together for more than 7 seconds until the phone restarts.

Then reconnect the charger and watch for the charging icon.

Step 9: Update the software and test in safe mode

• Update: Settings > Software Update > Check for updates, then follow the prompts.
• Safe mode: hold the Power (Side) button and Volume down, touch and hold Power off, then tap Safe mode.

If the phone charges in safe mode, a downloaded app is the cause, so remove apps you installed or updated recently.

Restart the phone to leave safe mode.

Step 10: Check battery health in Samsung Members

Open Samsung Members, tap Support, then Get started, run the full diagnostics first, stop the test, and choose Battery status.

Samsung lists fast drain after charging and unexpected shutdowns as signs the battery may be near the end of its life.

If your phone shows a battery performance degradation alert, Samsung recommends a service center inspection.

Step 11: When to contact Samsung

If nothing above works, the cause is probably hardware, such as the port or battery.

• Note your model and the steps you already tried.
• Check your warranty, since a battery replacement may be covered or paid depending on your terms.
• Book service at Samsung service and repair.
