How to Fix Galaxy S25 Overheating During Fast Charging
Overheating during fast charging is a common issue that can affect battery health and device performance. This guide provides actionable solutions to resolve the problem efficiently.
1. Check the Charger and Cable
Ensure your charging accessories are compatible and undamaged.
- Use only the original Samsung 25W+ charger and cable designed for the Galaxy S25.
- Inspect the cable for fraying, bends, or exposed wires; replace if damaged.
- Test with a different Samsung-certified charger/cable to rule out faulty accessories.
- Avoid third-party chargers not rated for Super Fast Charging.
2. Remove the Phone Case During Charging
Thick cases can trap heat and worsen overheating.
- Take off the phone case before plugging in the charger.
- Place the phone on a flat, hard surface (not fabric or bedding) to improve airflow.
3. Avoid Using the Phone While Charging
Screen activity and background apps increase heat generation.
- Turn off the screen and refrain from gaming or streaming.
- Enable Airplane Mode to reduce network-related battery drain.
4. Disable Fast Charging Temporarily
Slower charging reduces heat buildup.
- Go to Settings > Battery and Device Care > Battery > Charging Settings.
- Toggle off Fast Charging or Super Fast Charging.
- Re-enable the feature once temperatures normalize.
5. Update Software
Outdated software may have poor thermal management.
- Navigate to Settings > Software Update > Download and Install.
- Install pending updates and restart the device.
6. Charge in a Cool Environment
High ambient temperatures exacerbate overheating.
- Move the phone away from direct sunlight or hot surfaces.
- Charge in a room with air conditioning or a fan nearby.
7. Clear Background Apps
Resource-heavy apps strain the processor and battery.
- Swipe up from the bottom and hold to view recent apps.
- Tap Close All or swipe away unnecessary apps.
8. Check for Malware or Rogue Apps
Malicious software can overwork the device.
- Install a trusted antivirus app (e.g., Malwarebytes) and run a scan.
- Uninstall recently downloaded apps causing abnormal battery drain.
9. Reset Device Settings
Incorrect configurations might affect charging behavior.
- Open Settings > General Management > Reset.
- Select Reset All Settings (this won’t delete personal data).
10. Inspect the Charging Port
Dust or debris can cause improper connections and excess heat.
- Power off the device.
- Use a flashlight to check the port for lint or dirt.
- Gently clean with a dry toothbrush or compressed air.
11. Monitor Battery Health
A degraded battery may overheat more easily.
- Install Samsung Members app from the Galaxy Store.
- Open the app, go to Support > Device Diagnostics > Battery Status.
- Replace the battery if health is below 80%.
12. Factory Reset (Last Resort)
Software glitches may require a full reset. WARNING! This method will erase everything on your phone including contacts, photos, etc. Be sure to backup all data before trying this.
- Backup data via Settings > Accounts and Backup.
- Go to Settings > General Management > Reset > Factory Data Reset.
- Follow on-screen prompts to erase the device and set it up anew.
13. Use a Cooling Pad or Fan
External cooling can mitigate overheating during charging.
- Place the phone on a portable cooling pad or near a desk fan.
- Avoid covering the device while cooling accessories are active.
14. Contact Samsung Support
Persistent overheating may indicate hardware defects.
- Visit Samsung’s official support website to schedule a repair.
- Provide details about the issue and any troubleshooting steps already attempted.
