How to Fix Samsung Galaxy Overheating While Charging

Some warmth while charging is normal, but if your Samsung Galaxy becomes uncomfortably hot, it needs attention. Here's what's safe and how to fix excessive heat.

Normal vs. Concerning Temperatures

Situation	Temperature	Status
Light use while charging	35–40°C	✅ Normal
Gaming while charging	40–45°C	⚠️ Warm, acceptable
Too hot to hold	45°C+	❌ Needs attention

How to Fix Overheating During Charging

Remove your phone case while charging – Cases trap heat and significantly raise temperature.
Stop using the phone while charging – Running heavy apps during charging multiplies heat generation.
Use the official Samsung charger – Third-party chargers can deliver irregular power causing heat buildup.
Don't charge on soft surfaces – Charging on a bed or pillow blocks air circulation. Charge on a hard flat surface.
Check your environment – Charging in direct sunlight or in a hot car will always cause overheating.
Update One UI – Charging-related thermal bugs are sometimes patched in software updates.

Safety Warning

If your Samsung is hot to the touch, stops charging partway through, or shows a temperature warning, stop charging immediately, allow it to cool, and check for physical damage to the battery (bulging back panel is a red flag).

If the problem persists, visit a Samsung Service Center for a battery diagnostic.
