Samsung S23 Not Charging After Update – What UK Users Should Do

Many UK Samsung S23 owners experience charging issues immediately after a system update. Whether you’re in London, Manchester, Birmingham, or Edinburgh, the symptoms are often the same: phone plugged in but not charging, intermittent connections, or fast charging disappearing.

This guide explains practical steps, real user insights, and UK-specific repair options. Internal links are integrated for relevant AvNexo hubs:

  • Battery & Power Hub
  • Connectivity & Network Hub

Why Updates Cause S23 Charging Problems

Most post-update charging issues are software-related, though hardware may occasionally play a role:

  • Corrupted USB settings or system cache after the update
  • Moisture detection errors, particularly in coastal UK cities like Brighton and Bournemouth
  • Third-party apps conflicting with USB-C charging protocols
  • Firmware changes that affect power delivery

Step 1 – Test With Certified Chargers and Cables

UK users should always start with:

  • Samsung official chargers (25W or 45W PD)
  • High-quality USB-C to USB-C PD cables
  • Chargers approved by UK carriers: EE, O2, Vodafone, Three

Many users find the phone charges immediately with the correct cable, proving the issue is not the port itself.

Step 2 – Inspect and Clean the USB-C Port

Debris or lint can prevent charging. Use:

  • A wooden toothpick or soft brush to remove debris
  • Compressed air for thorough cleaning

Check for bent or corroded pins — a common cause of intermittent charging.

Step 3 – Reset USB Settings and Clear System Cache

  1. Open Settings → Apps → Show system apps
  2. Search for USBSettings, USB Device Manager, USB Debugging
  3. Clear cache and data for each service
  4. Restart the phone

Users in Leeds and Sheffield report that this often restores normal charging.

Step 4 – Safe Mode Test

Third-party apps can block charging after updates:

  1. Hold Power button
  2. Press and hold Power Off
  3. Select Safe Mode

If the S23 charges in Safe Mode, uninstall recently updated or battery optimisation apps.

Step 5 – Moisture Detection Diagnostics

Even without water, the S23 may falsely detect moisture after updates:

  • Unplug the phone and leave in a dry area
  • Enable Airplane Mode to reduce background power use
  • Wait 30–60 minutes and retry charging

Users in Liverpool and Glasgow have fixed charging problems using this simple step.

Step 6 – Samsung Members Diagnostics

Run built-in tests for USB, battery, and charging:

  1. Open Samsung Members → Support → Diagnostics
  2. Run the tests

Results indicate if a port is physically damaged or if software remains the issue.

Step 7 – Cache Partition Wipe

  1. Turn off the device
  2. Hold Volume Up + Power
  3. Select Wipe cache partition
  4. Reboot the phone

This step solves intermittent charging for many UK S23 users.

Hardware Considerations

If software fixes fail, the problem may be physical:

  • Loose port pins
  • Corrosion or debris not fully removed
  • Charging controller IC issues

UK Repair Options

  • Samsung Authorised Service Centres: London, Manchester, Birmingham – £90–£140
  • Local independent repair shops: Leeds, Sheffield, Bristol – £45–£85
  • Mail-in repair services: For towns like Swansea or Newcastle

Preventing Future Charging Issues

  • Use certified chargers from Samsung or UK carriers
  • Restart after each update
  • Clean the USB-C port regularly
  • Avoid humid rooms when charging
  • Keep Samsung Members and Galaxy Store apps updated

Conclusion

Most Samsung S23 charging issues post-update in the UK are software-related. Following this step-by-step guide usually restores normal charging without requiring a repair. Hardware intervention is only necessary if the port itself is physically damaged.
