How to Fix Android Phone Overheating Problems (Step-by-Step Beginner Guide)

Why Android Phones Overheat (And Why You Should Fix It Quickly)

If your Android phone becomes hot while charging, browsing, or using apps, it can feel scary — and honestly, it should not be ignored.

This overheating issue happened to me personally on my Infinix device, and I’ve helped many people fix the same problem using these exact steps.

The good news is:

Most overheating problems are caused by simple things like heavy apps, background activity, poor ventilation, or charging issues — and you can fix them safely at home.

Let’s go through the solutions properly.

First: Know What Overheating Really Means

A phone is overheating when:

• The back becomes uncomfortably hot
• You see a temperature warning message
• The phone starts lagging or freezing
• Battery drains unusually fast
• Charging slows down automatically

Android phones are designed to warm up slightly, but extreme heat is a problem.

Fix 1: Remove the Phone Case Immediately

Many people don’t realize phone cases trap heat.

Do this now:

1. Take off your phone case
2. Place the phone on a flat open surface (not on a bed or pillow)
3. Let it cool for 5–10 minutes

This simple step has worked instantly for me more than once.

Fix 2: Stop Charging While the Phone Is Hot

Charging generates heat naturally.

If your phone is overheating while charging:

1. Unplug the charger immediately
2. Let the phone cool down first
3. Avoid using the phone heavily while charging

Never charge under a pillow or inside a bag.

Fix 3: Close Heavy Apps Running in the Background

Apps like TikTok, Facebook, YouTube, and games can overwork your CPU.

To close background apps:

1. Tap the Recent Apps button
2. Swipe away all unused apps
3. Restart the phone if needed

This reduces heat fast.

Fix 4: Check Which App Is Causing the Heat

Sometimes one app is the main culprit.

To find it:

1. Open Settings
2. Tap Battery
3. Select Battery Usage
4. Look for apps using unusually high power

If one app is draining 30–50%, uninstall or restrict it.

Fix 5: Turn On Battery Saver Mode

Battery Saver reduces CPU load and background activity.

Enable it:

1. Open Settings
2. Tap Battery
3. Turn on Battery Saver

This helps cool the phone down quickly.

Fix 6: Reduce Screen Brightness and Refresh Rate

High brightness produces heat.

Adjust brightness:

1. Swipe down from the top
2. Lower the brightness slider

If your phone has high refresh rate:

1. Open Settings
2. Tap Display
3. Select Refresh Rate
4. Choose Standard instead of High

Fix 7: Turn Off Hot Features You Don’t Need

Some features generate extra heat:

• Mobile Hotspot
• Bluetooth
• GPS Location
• 5G data

Turn them off:

1. Swipe down Quick Settings
2. Disable unused toggles

Fix 8: Avoid Using Your Phone in Direct Sunlight

Heat + sunlight is a dangerous combination.

Never leave your phone:

• On a car dashboard
• Under the sun
• Near cooking areas

Phones overheat faster in warm environments.

Fix 9: Clear Cache of Heavy Apps

Corrupted cache can cause apps to misbehave and overheat.

Clear cache safely:

1. Open Settings
2. Tap Apps
3. Select the app (e.g., TikTok)
4. Tap Storage & Cache
5. Tap Clear Cache

Do not clear data unless necessary.

Fix 10: Update Your Android System and Apps

Old software can cause overheating bugs.

Update Android:

1. Open Settings
2. Tap System
3. Tap Software Update
4. Install any available update

Update apps:

1. Open Google Play Store
2. Tap your profile icon
3. Tap Manage apps & device
4. Tap Update All

Fix 11: Use Only Original or Quality Chargers

Fake chargers often cause heating and battery damage.

Check your charger:

• Use the original charger or trusted brand
• Avoid cheap unknown cables
• Do not charge with damaged cords

This is one of the most common overheating causes I’ve seen.

Fix 12: Restart Your Phone (Simple but Powerful)

Restarting stops hidden background processes.

Restart properly:

1. Hold the Power button
2. Tap Restart
3. Wait for the phone to boot fully

This clears temporary overheating triggers.

Fix 13: If Overheating Happens Daily, Do a Safe Factory Reset (Last Option)

Only do this if nothing works.

Before reset:

1. Back up your photos and files
2. Open Settings
3. Tap System
4. Tap Reset Options
5. Select Erase All Data (Factory Reset)

This removes corrupted system issues.
