Samsung Phone Not Charging? 10 Quick Fixes
Quick Fix
Clean the charging port with a wooden toothpick to remove lint and debris – this is the most common cause. Then try a different cable and charger. If wireless charging works but wired doesn’t, the port needs cleaning or repair.
Understanding Samsung Charging Problems
When your Samsung Galaxy phone won’t charge, you might see no response when plugged in, very slow charging, or “Moisture detected” errors. This affects all Samsung models from budget A-series to flagship S and Z series.
Common causes include dirty charging ports, damaged cables, software glitches, or battery issues. The USB-C ports on newer Samsung phones can collect pocket lint easily.
Most charging issues are fixable without repair, especially if the phone worked fine before.
Method 1: Clean the Charging Port
- Power off your phone
- Use a flashlight to look inside the port
- Use a wooden or plastic toothpick
- Gently scrape debris from the port
- Don’t use metal objects
- Use compressed air to blow out dust
- Try charging again
Method 2: Try Different Cable and Charger
- Cables are often the problem
- Try your cable with another device
- Try a different cable with your phone
- Use Samsung original or certified chargers
- Cheap cables can damage phones
- Try plugging into a wall outlet, not computer
Method 3: Restart Your Phone
- Press and hold Power + Volume Down
- Tap Restart
- Wait for phone to fully boot
- Try charging after restart
- Software glitches can prevent charging
Method 4: Boot to Safe Mode
- Press and hold Power button
- Touch and hold Power off on screen
- Tap Safe mode
- Phone restarts with third-party apps disabled
- Try charging in Safe Mode
- If it works, an app is interfering
- Restart normally and uninstall recent apps
Method 5: Clear USB Settings Cache
- Go to Settings > Apps
- Tap three dots > Show system apps
- Find USBSettings
- Tap Storage > Clear cache and Clear data
- Restart phone
- Try charging again
Method 6: Disable Moisture Detection (If Error Shows)
- If you see “Moisture detected” but port is dry
- Ensure port is completely dry
- Restart phone
- If error persists, try wireless charging
- Clear cache from Recovery Mode
- Sensor may need professional reset
Method 7: Try Wireless Charging
- If your Samsung supports wireless charging
- Place on a Qi wireless charger
- If wireless works but wired doesn’t, port is the issue
- Use wireless as backup while troubleshooting
- Wireless charges slower but avoids port problems
Method 8: Wipe Cache Partition
- Power off the phone
- Hold Volume Up + Power until logo appears
- Release Power but keep holding Volume Up
- In Recovery menu, use volume to select “Wipe cache partition”
- Press Power to confirm
- Select “Reboot system now”
- Try charging after reboot
Preventing Charging Issues
- Use Samsung original or certified chargers
- Keep charging port clean
- Don’t charge in extreme temperatures
- Avoid cheap third-party cables
- Don’t force the cable in if it doesn’t fit easily
FAQ
Why does my Samsung charge slowly?
Using a low-wattage charger, bad cable, background apps, or charging while using the phone. Use Samsung’s fast charger (25W+) and close apps while charging.
Why does my phone say “Moisture detected”?
The USB port has moisture sensors. Dry the port thoroughly with compressed air. Don’t blow into it – breath adds moisture. Wait a few hours if it was wet.
Can I use any USB-C charger for Samsung?
Yes, but for fastest charging use Samsung or compatible fast chargers (PD or QC). Generic chargers work but charge slower.
Why does my Samsung only charge when off?
Software or power management issue. Boot to Safe Mode, clear USB cache, or perform factory reset as last resort.
How do I know if my Samsung battery is bad?
Check Settings > Battery for battery health. If battery drains very fast, swells the phone, or won’t hold charge, it needs replacement.
Does fast charging damage the battery?
Modern Samsung phones manage fast charging safely. The phone slows charging when hot or near full. It doesn’t significantly reduce battery lifespan.
