Let’s start!

1. Why Your Mobile Heats Up

Before learning how to fix mobile heating problem, you must understand why it happens. Heating usually occurs when the processor (CPU), GPU, battery, or internal components are forced to work harder than usual.

Here are the most common causes:

How to Fix Mobile Hanging Problem

a) Heavy apps running in background

Facebook, Instagram, Snapchat, Chrome, and games keep running even after you close them, causing CPU load.

b) Playing games for too long

Graphic-heavy games like BGMI, Free Fire, COD Mobile put extreme stress on the GPU.

c) Fast charging

Fast chargers generate more heat due to higher power transfer.

d) Poor ventilation / Using phone while charging

When you use the phone during charging, heat gets trapped quickly.

e) Low-quality or duplicate chargers

Cheap chargers do not regulate voltage properly, which causes overheating.

f) Storage almost full

Phones heat up when storage is 90%+ full because system processes struggle.

g) Software bugs or outdated apps

Unoptimized apps can create sudden random heating.

h) High temperature environment

Outdoor heat, direct sunlight or a hot room can instantly warm the device.

2. Is Mobile Heating Dangerous?

Sometimes heating is normal — especially while gaming or charging — but excessive heating is dangerous.

Extreme overheating may cause:

• Battery lifespan reduction
• Faster battery drain
• App crashes
• Phone slowing down
• Auto shut down
• Internal hardware damage
• Risk of battery swelling (very dangerous)

If your phone crosses 45–50°C, you must cool it down immediately.

3. Quick Ways to Cool Down Your Phone (Instant Fixes)

If your phone is already hot, try these fast cooling methods:

1. Remove the back cover

Covers trap heat. Removing it improves airflow.

2. Turn off mobile data, Wi-Fi & Bluetooth

Connectivity features create constant background load.

3. Close all apps

Swipe away recent apps, especially heavy ones.

4. Turn on Airplane mode for 2–3 minutes

This instantly drops temperature.

5. Stop using the phone for 5–10 minutes

Let the hardware rest.

6. Place it on a cool surface (not cold!)

Table → OK
Fridge → NEVER
Ice → NEVER
AC vent → OK

Sudden temperature shock can damage the motherboard, so avoid extreme cooling.

4. How to Fix Mobile Heating Problem (Full Step-by-Step Solutions)

Now let’s understand the proper methods to fix the heating issue completely.

Solution 1: Reduce Background App Usage

Background apps are the #1 reason behind overheating.

Steps:

1. Open Settings
2. Go to Apps / App Manager
3. Force stop apps you don’t use
4. Disable auto-start features
5. Disable background data for heavy apps

How to Protect Your Computer from Viruses

This reduces CPU load and directly cools the phone.

Solution 2: Keep Storage Clean and Free (at least 20%)

When your phone’s storage becomes full, the system struggles, and processor load increases.

Action Steps:

✔ Delete unnecessary photos/videos
✔ Clear WhatsApp media
✔ Uninstall apps you don’t need
✔ Clear cache regularly
✔ Move files to cloud storage

Aim to keep 20–25% free storage for smooth performance.

Solution 3: Avoid Using Phone While Charging

Using the phone while charging creates a triple load:

• CPU processing apps
• Battery charging
• Screen heating

This combination causes extreme heat.

Tip:

Charge your phone to 80–90% and unplug. This improves battery health too.

Solution 4: Disable High Battery Consuming Features

Some features drain battery and heat device unnecessarily.

Disable them if not needed:

• GPS
• Mobile Hotspot
• NFC
• Bluetooth
• Background Sync
• Auto-brightness (use manual brightness)

Solution 5: Turn Off High Graphics Mode

If you play games:

• Reduce graphics
• Lower frame rate
• Enable battery saver mode
• Avoid long gaming sessions

Continuous gaming = continuous heating.

Solution 6: Update Apps and System Software

Outdated apps have bugs that increase CPU usage.

Steps:

1. Open Play Store
2. Tap “Update All”
3. Update system software from Settings

This fixes many heating issues instantly.

Solution 7: Use Original Branded Charger Only

Cheap chargers → voltage fluctuation → overheating + battery damage.

Always use:

✔ Original charger
✔ Same wattage
✔ Good quality cable

Avoid fast charging if your phone already heats up.

Solution 8: Limit Screen Brightness

High brightness consumes huge power and heats up the screen.

Keep brightness below 50% when possible.

Solution 9: Remove Live Wallpapers

Live wallpapers use GPU 24/7.

Use a static dark wallpaper instead.

Solution 10: Stop Auto App Sync

Auto-sync = constant background activity.

Turn it off unless required.

5. Long-term Prevention Tips for Mobile Heating

Now that you know how to fix mobile heating problem, let’s look at long-term habits to prevent it permanently.

1. Do not game while charging

This is the worst combo for phone health.

2. Avoid direct sunlight

Phones absorb heat quickly outdoors.

3. Charge between 20% to 90%

Best range for battery health.

4. Don’t keep your phone on bed or pillows

These trap heat and worsen the temperature.

5. Use battery saver mode

Reduces CPU load significantly.

6. Avoid cheap power banks

Use branded ones with safety chips.

7. Restart phone every 2–3 days

Clears memory and resets background processes.

6. Common Myths About Mobile Heating

❌ Myth 1: Putting phone in fridge cools it faster

Truth: It can cause internal condensation → damage.

❌ Myth 2: Heating problem always means battery issue

Truth: Most heating is due to apps, background load, or network.

❌ Myth 3: Fast charging is harmful

Truth: Harmful only when used with cheap chargers or cheap cables.

❌ Myth 4: Closing apps always saves heating

Truth: Some apps auto-start again unless disabled.

7. When Should You Visit a Service Center?

You should consider professional help if:

✔ Phone heats even without use
✔ Battery drains very fast
✔ Phone shuts down automatically
✔ Back panel bulges (battery swelling — dangerous!)
✔ Heating started after water damage
✔ Charging port becomes hot instantly

These are signs of hardware-level issues.

8. FAQs About Mobile Heating

Q1. Is it normal for mobile to heat while charging?

Yes, slight heating is normal. Extreme heating is not.
