How do I fix my Samsung from overheating?

Overheating is a common issue that Samsung phone users face. It can cause performance problems, battery drain, and even permanent damage if left unchecked. Thankfully, there are several ways you can prevent and fix overheating on your Samsung device.

What Causes a Samsung Phone to Overheat?

There are a few main culprits when it comes to overheating on Samsung phones:

  • Using resource-intensive apps – Apps that use a lot of processing power like games, videos, and navigation can make the phone work harder and heat up.
  • Charging – Charging generates heat, so using fast chargers and charging while using the phone can contribute to overheating.
  • Poor ventilation – Lack of air circulation prevents heat from dissipating.
  • Direct sunlight – Leaving your phone in hot cars or direct sunlight heats up the device.
  • Faulty battery – Damaged or swollen batteries can cause the phone to overheat.
  • Too many background processes – Having too many apps and processes running bogs down the system.
  • Software issues – Bugs, old software, and corrupt files can affect system resources.
  • Hardware problems – Issues with the processor or motherboard components can lead to overheating.

How to Tell if Your Samsung is Overheating

Here are some signs that your Samsung phone may be overheating:

  • It feels very hot to the touch
  • Apps are freezing, crashing, or running slow
  • The phone turns off on its own
  • You get warning messages about temperature
  • Battery life drains faster than usual
  • Performance seems sluggish
  • The phone doesn’t charge properly

You’ll typically notice these issues after prolonged use of demanding apps, intense multitasking, or long charging sessions. The phone may be uncomfortably warm in your hand or pocket. Keep an eye out for these indicators of overheating.

Immediate Solutions to Cool a Samsung Phone

If your Samsung is overheating right now, there are a few quick things you can do to cool it down:

  • Turn it off – Shut down the phone completely if it feels extremely hot.
  • Remove the case – Take off any protective cases or covers.
  • Get it out of the sun – Move it into a shaded or air-conditioned area.
  • Stop multitasking – Close any apps and processes you aren’t using.
  • Turn on Airplane mode – This suspends wireless connections that use battery.
  • Connect a fan – Point a fan directly at your phone to distribute heat.
  • Use a cooling pad – These pads draw heat away from hot spots.

Avoid using the charger and let the phone rest for a bit. These quick fixes can lower the temperature and prevent damage from sustained overheating.

How to Prevent Overheating on Samsung Phones

To help stop overheating problems before they start, implement these tips:

  • Update your software – Download the latest OS and app updates which may fix bugs.
  • Close background apps – Don’t let too many apps run in the background needlessly.
  • Disable unnecessary features – Turn off Bluetooth, GPS, and syncing when not in use.
  • Limit gaming and videos – These put a lot of strain on the phone components.
  • Use a lighter wallpaper – Dark images make the screen work harder.
  • Take it out of its case – Ensure good air circulation around the phone.
  • Avoid direct sunlight – Don’t leave your phone in hot cars or outside.
  • Replace old batteries – Worn out batteries are prone to overheating.
  • Use original chargers – Third-party chargers may not regulate temperature well.
  • Clean out vents – Compressed air can dislodge dust buildup in vents.

Proactively managing usage and being mindful of heat generation can reduce the likelihood of CPU and battery overload.

Fix Software-Related Overheating

If you suspect the overheating stems from a software issue, try these troubleshooting steps:

  1. Restart your phone – This clears temporary glitches and processes.
  2. Check for OS updates – Install the latest security patches and upgrades.
  3. Update problem apps – Upgrade apps that freeze or crash, causing CPU strain.
  4. Uninstall unnecessary apps – Get rid of apps and bloatware you don’t really use.
  5. Reset app preferences – This will clear any problematic customized settings.
  6. Reset network settings – Inputting your WiFi, Bluetooth and other connections can fix bugs.
  7. Clear application cache – Wipe cached app data that may be corrupted.
  8. Factory reset – As a last resort, completely wipe the device.

Work through these solutions one-by-one until you determine the software or app causing the overheating. Target the culprit and the issue should be resolved.

Fix Hardware-Related Overheating

If you’ve ruled out software as the cause, it’s likely a hardware component that needs attention. Here’s how to handle suspected hardware issues:

  1. Check the battery – Examine it for swelling and damage. Consider replacing it if needed.
  2. Inspect vents and ports – Clean out any dust, dirt or debris with compressed air.
  3. Take it apart carefully – A qualified repair shop can assess internal components.
  4. Replace damaged parts – Motherboards, charging ports, or processors may need replacing.
  5. Improve airflow – Add internal cooling mods or external clip-on fans.
  6. Use a case – Open-air or water-cooled cases can enhance heat dissipation.
  7. Apply new thermal paste – Reapplying this can optimize heat transfer from the CPU.

Hardware solutions will require technical expertise to execute properly. Speak to a repair technician if you aren’t comfortable taking these steps yourself.

Best Practices to Avoid Overheating

Here are some wise overheating prevention habits to get into:

  • Don’t use fast chargers for long sessions – Quick charging generates more heat.
  • Avoid wireless charging – Wired charging converts energy more efficiently.
  • Select optimized battery mode – This balances performance and battery life.
  • Take phones out of cases periodically – Ensure heat can escape.
  • Limit gaming and video calls – Heavy graphics and video are very taxing.
  • Close unused apps and tabs – Too many can overwhelm the CPU with time.
  • Put off updates until charging – Updating uses a lot of processing power.
  • Avoid extreme hot or cold – Outside temperature extremes pass heat to the device.
  • Power down at night – Gives the phone a chance to cool completely.

Building these habits will go a long way towards promoting a cool, healthy phone environment.

Quick Fixes for an Overheated Samsung

If your Samsung is running hot right now, refer to this checklist for fast relief:

Solution How it Helps
Turn it off Allows components to cool completely
Remove case Eliminates insulation trapping heat
Move to shade Removes heating effects of direct sunlight
Close apps Stops processing strain from running apps
Enable Airplane Mode Suspends battery drain from wireless connections
Apply cooling fan Distributes and diffuses concentrated heat
Use cooling pad Draws heat away from hot internal components

These solutions provide fast temporary relief. For long-term overheating avoidance, use the preventative measures outlined above.


In summary, overheating on Samsung phones stems from intensive processing, poor ventilation, faulty hardware and other factors. Monitor your phone for signs of overheating like slow performance and random shutdowns. Respond quickly by turning off the phone, removing cases, closing apps, and applying cooling methods. Prevent problems in the future by updating software, limiting gaming, using optimized modes, and building phone-cooling habits.

With vigilance and prompt action, you can get an overheated Samsung phone back to normal operation. Be proactive about prevention and device care to maximize the phone’s lifespan and effectiveness.
