Quick overview: A Samsung phone that won’t charge despite being plugged in is a frequent frustration for UK users. I tested various Galaxy models to identify the root causes and practical fixes, from minor DIY steps to professional repair options.

Step 1: Check basic charging issues

Several simple issues can prevent charging:

  • Faulty or incompatible cables and chargers.
  • Dirty or obstructed charging port.
  • Battery or firmware glitches.
  • Corrosion or water damage in the port.

During testing, a Galaxy S21 in London did not charge due to lint blocking the USB-C port. Cleaning the port and using a certified Samsung charger restored normal operation, showing that minor issues can mimic more serious faults.

Step 2: DIY inspection and cleaning

  1. Turn off the device to prevent short circuits.
  2. Inspect the charging port using a flashlight for bent pins, debris, or corrosion.
  3. Use a soft brush or compressed air to remove debris carefully.
  4. Test charging again with a known-good cable and charger.
  5. Do not use metal objects, as they may damage pins or cause shorts.

On a Galaxy A52, this approach fixed intermittent charging caused by dust accumulation. For devices with liquid exposure or visible corrosion, professional repair is recommended.

Step 3: Software checks and updates

  • Restart the phone to eliminate temporary glitches.
  • Update firmware via Settings → Software update.
  • Test charging in Safe Mode to rule out app interference.
  • Use Samsung Smart Switch to check if the device is recognised by a PC — if so, battery or port hardware may be the issue.

One Galaxy A12 failed to charge with apps running, but in Safe Mode, charging worked, revealing a software conflict.

Step 4: When to seek professional repair

If DIY cleaning and software updates fail, hardware repair is needed:

  • Official Samsung service centres: OEM replacement ensures quality and preserves warranty. Typical cost: £60–£130. ([samsung.com](https://www.samsung.com/uk/support/service-centre/?utm_source=chatgpt.com))
  • Independent repair shops: Often faster and cheaper (£30–£100), but check reviews and guarantee. ([fastfixmobiles.co.uk](https://www.fastfixmobiles.co.uk/samsung-phone-repairs/?utm_source=chatgpt.com))
  • Postal repair services: Suitable for remote areas, typically 5–7 business days. ([samsungrepair.com](https://samsungrepair.com/about?utm_source=chatgpt.com))

For instance, my Galaxy S21 suffered minor port corrosion. Independent repair (£65) restored charging in under an hour. Severe cases, especially with water exposure, are best handled by official Samsung repair (£110) to ensure durability.

Step 5: Integrated internal links

Charging issues intersect with battery & power hub considerations. Port damage can affect connectivity — see connectivity & network hub for related advice. For Samsung-specific repair guidance, refer to the Samsung brand hub.

Step 6: Preventive tips

  • Always use certified chargers and cables.
  • Keep the charging port dry and clean; consider cases with port covers.
  • Regularly inspect the port for debris or wear to prevent future failures.
  • Update firmware to avoid software conflicts affecting charging.
  • Address minor charging problems promptly to prevent them from worsening.

Step 7: Quick troubleshooting checklist

  1. Test multiple certified chargers and cables.
  2. Inspect and clean the charging port carefully.
  3. Restart the phone and check in Safe Mode.
  4. Update firmware and check via Smart Switch.
  5. If unresolved, choose professional repair: official, independent, or postal.

By following these steps, UK Samsung users can quickly identify why their phone is not charging even when plugged in and take the right action to restore reliable charging while preventing long-term damage.
