How to Stop Phone from Overheating
Why Is Your Phone Overheating?
Phone overheating happens when the internal processor (CPU) and battery generate more heat than the device can release.
Common causes:
-
Heavy gaming
-
Charging while using
-
Background apps
-
Poor signal strength
-
Software bugs
-
Old battery
-
Direct sunlight exposure
Normal phone temperature: 30°C–40°C
Danger zone: Above 45°C
If your phone feels too hot to hold comfortably, it needs attention.
🚨 How to Cool Down Your Phone Immediately
If your phone is heating right now, do this:
-
Turn on Airplane Mode
-
Remove the phone case
-
Stop charging immediately
-
Close all background apps
-
Keep it in a cool, shaded area
-
Switch it off for 10–15 minutes
⚠️ Do NOT put your phone in the fridge.
Sudden temperature change causes condensation and motherboard damage.
🔥 Main Reasons for Phone Heating Issues

Using low-quality chargers or fast charging repeatedly increases battery heat.
Fix:

🔋 What Is the 80-20 Battery Rule?
The 80-20 rule means:
-
Don’t let battery drop below 20%
-
Don’t charge above 80%
This reduces lithium-ion battery stress and prevents overheating long term.
Charging to 100% daily increases heat cycles.

Yes.
Long-term overheating can:
-
Reduce battery lifespan

Cause random shutdowns
Ignoring it is expensive.
