Most charging problems are a bad cable or lint packed in the port. Try a different cable and wall adapter, then power the phone off and gently clean the port with a wooden toothpick and a flashlight. Never use metal or liquids. If wireless charging works but the cable does not, the port is the problem. If cleaning does not help, the port likely needs repair.
Step 1: Rule out the cable and charger
- Try a different cable and a different wall adapter. Cables often fail near the ends.
- Plug into a wall outlet, not a computer or car port.
- If your phone supports wireless charging, try it. If wireless works but the cable does not, the port or cable is the problem, not the battery.
Step 2: Clean the port safely
- Turn the phone off.
- Shine a flashlight into the port. Pocket lint often packs into the back of the port so the cable cannot seat fully.
- Gently scrape along the back wall of the port with a wooden toothpick. Go slowly, and do not press on the pins.
- Tap the phone gently to shake the lint out, then try the cable again.
Do not use metal pins, paper clips or needles, which can short or bend the contacts. Do not spray liquids or cleaners into the port. Avoid blasting compressed air straight in, which can push lint deeper.
Step 3: Rule out software and settings
- Restart the phone and install any updates.
- On iPhone, charging that pauses at 80 percent is usually Optimized Battery Charging or the 80% Limit setting, not a fault. Check Settings > Battery > Charging.
- On Samsung, a “moisture detected” warning means the port is wet or dirty. Dry the phone before charging.
Signs the port needs repair
- The cable feels loose or falls out.
- It only charges at a certain angle.
- You see bent pins, burn marks or green corrosion in the port.
- Nothing happens with several cables, even after cleaning.
A worn or damaged port is a common repair. On many phones the port is part of a flex cable that can be replaced without touching your data.
