How to Fix Samsung Galaxy Overheating While Charging – UK Safety Tips

Understanding Overheating Issues on Samsung Galaxy Devices

Overheating while charging is a common concern for Samsung Galaxy users in the UK. It can occur due to high-performance apps running in the background, faulty cables, incompatible chargers, or battery issues. Persistent overheating not only slows charging but can also damage the battery over time. From experience, even small software or accessory issues can trigger significant temperature rises.

Step-by-Step Solutions to Prevent Overheating

Use Official Chargers and Cables: Always use Samsung-approved USB-C cables and fast chargers. Third-party or low-quality adapters may generate excess heat.
Check USB Port and Charging Connection: Ensure the USB-C port is clean and free from dust or debris. Settings → Device Care → Battery can alert you to unusual charging behaviour.
Reduce Device Usage While Charging: Avoid gaming, video streaming, or heavy app usage during charging. Overuse generates heat that accumulates in the battery.
Enable Fast Charging Properly: Settings → Device Care → Battery → Charging → enable “Fast Charging” or “Super Fast Charging” for compatible models. Using the wrong charging mode can stress the battery.
Close Background Apps: Tap Recent Apps → swipe away non-essential apps. Background apps can push the processor to high loads, raising temperature.
Remove Case if Necessary: Some phone cases trap heat. During fast charging, temporarily remove thick or insulated cases.

Advanced Checks

Check battery health via Settings → Device Care → Battery → Battery Usage. UK users should monitor for swelling or unusual drain patterns.
Perform Safe Mode test: Power off → hold Power → tap and hold “Power Off” → select Safe Mode. If overheating decreases, a third-party app is likely causing the issue.
Keep software updated: Settings → Software Update → Download and Install. Samsung often releases patches that optimise charging and heat management.
Use Samsung Diagnostics (*#0*#) → Battery or Sensor tests to detect abnormal temperature readings or hardware faults.

Tips from Real-World Experience

Charging on a flat, hard surface improves heat dissipation compared to soft surfaces like beds or sofas.
High ambient temperatures (UK summer heatwaves or poorly ventilated rooms) can amplify overheating. Avoid direct sunlight.
Regularly check the Battery & Power hub for UK-specific guidance on maintaining battery health.
Apps like Samsung Game Launcher may run performance boosters in the background; disabling them during charging helps control temperature.

Common Mistakes to Avoid

Ignoring overheating and continuing heavy usage — can permanently damage battery cells.
Using non-Samsung fast chargers — may deliver unstable voltage, causing heat spikes.
Charging under blankets, pillows, or in pockets — blocks heat dissipation.

Preventive Measures

Regularly inspect cables and chargers for wear or damage.
Keep software and firmware up-to-date to benefit from thermal management improvements.
Enable battery optimisation features: Settings → Device Care → Battery → Optimise now.
Refer to the Performance & System hub and Connectivity & Network hub for tips on reducing background load and heat during charging.
Consider battery replacement via authorised service if overheating persists despite following best practices (Samsung hub).

Conclusion

Samsung Galaxy overheating while charging can usually be managed with proper cables, settings adjustments, background app management, and safe charging practices. UK users should pay attention to environmental factors, software updates, and battery health to ensure safe and efficient charging. Following these steps reduces the risk of battery damage and keeps your device operating smoothly.
