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:

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
- Open Settings → Apps → Show system apps
- Search for USBSettings, USB Device Manager, USB Debugging
- Clear cache and data for each service
- 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:
- Hold Power button
- Press and hold Power Off
- 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:
- Open Samsung Members → Support → Diagnostics
- Run the tests
Results indicate if a port is physically damaged or if software remains the issue.
Step 7 – Cache Partition Wipe
- Turn off the device
- Hold Volume Up + Power
- Select Wipe cache partition
- 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.
