Why Is My Phone Overheating? Causes and Proven Fixes That Actually Work


Last summer, I noticed something strange with my phone. After just a few minutes of scrolling social media or watching videos, my phone became uncomfortably hot. Sometimes it heated up so much that I had to put it down. At first, I ignored it, thinking it was normal. But then my phone started lagging, the battery drained faster, and apps began crashing.

If your phone is also overheating, don’t panic. Phone heating is a very common problem, and in most cases, it’s caused by usage habits, background apps, poor ventilation, or battery stress, not a serious hardware fault. The key is understanding why your phone is overheating and fixing the root cause before it damages your battery or internal components.

In this guide, I’ll explain all the reasons your phone overheats and share step-by-step solutions that actually work on both Android and iPhone.

Is Phone Overheating Normal?

A slightly warm phone is normal, especially during charging or heavy use. However, overheating becomes a problem when:

  • The phone feels too hot to hold

  • You see a temperature warning

  • The phone slows down or shuts down

  • Battery drains very fast

If these signs appear regularly, you need to fix the issue.

Common Reasons Why Your Phone Is Overheating

Understanding the causes makes fixing the problem much easier.

1. Heavy App Usage

Apps like games, video streaming apps, social media, and camera apps use a lot of CPU and GPU power.

I once played a high-graphics game for 30 minutes, and my phone felt like it was burning. This is because heavy apps force the processor to work harder, producing more heat.

2. Too Many Background Apps

Even when you’re not using them, some apps keep running in the background:

  • Social media syncing

  • Location tracking

  • Notifications and updates

These apps quietly consume resources and raise phone temperature.

3. Charging While Using the Phone

Using your phone during charging is one of the biggest causes of overheating.

  • Charging already generates heat

  • When you add gaming, video calls, or browsing, the temperature rises quickly

4. Poor Network Signal

Weak mobile signal forces your phone to search continuously for a network.

  • This constant searching increases power usage and causes overheating—especially in basements or during travel

5. High Screen Brightness

Your screen is one of the largest power consumers.

  • Maximum brightness + long screen time = more heat

6. Hot Weather & Direct Sunlight

External temperature matters. Leaving your phone:

  • In a parked car

  • Under direct sunlight

  • Near heat sources

can quickly cause overheating.

7. Old or Degraded Battery

As batteries age, they become less efficient.

A battery older than 2–3 years may:

  • Heat up faster

  • Drain quickly

  • Cause random shutdowns

8. Software Bugs or Outdated OS

Sometimes overheating starts after a system update.

  • Bugs or unoptimized apps can force the processor to overwork continuously

Step by Step Fix: How to Stop Your Phone from Overheating

Follow these proven solutions in order.

1. Remove the Phone Case Temporarily

Thick cases trap heat.

  • Remove the case while charging

  • Avoid heavy covers during gaming

This allows heat to escape more easily.

2. Close Background Apps

Freeing system resources reduces heat instantly.

  • Close unused apps

  • Avoid multitasking

  • Restart your phone if needed

I noticed my phone cooled down within minutes after closing unused apps.

3. Reduce Screen Brightness

  • Lower brightness to 50–60%

  • Enable auto-brightness

  • Reduce screen timeout


This small change makes a big difference.

4. Avoid Using Phone While Charging

If possible:

  • Let the phone charge undisturbed

  • Avoid gaming or video calls

  • Don’t keep it under a pillow

Charging + usage = excessive heat.

5. Switch Off Unused Features

Turn off features you’re not using:

  • Bluetooth

  • GPS

  • Mobile hotspot

  • 5G (if not needed)

This reduces background power usage.

6. Check for Problematic Apps

Some apps cause abnormal heating.

  • Go to Settings → Battery Usage

  • Identify apps using excessive power

  • Uninstall or restrict them

I once removed a single app that was causing most of the overheating.

7. Update Apps and System Software

Updates often fix performance and heating issues.

  • Update all apps

  • Install system updates

Outdated software can overwork your processor.

8. Avoid Extreme Temperatures

  • Don’t leave phone in direct sunlight

  • Avoid hot environments

  • Keep phone in shade when outdoors

Phones are sensitive to heat.

9. Reset Network Settings (If Heating During Data Use)

If your phone heats mainly during mobile data use:

  • Reset network settings

  • Switch between 4G/5G manually

  • Use Wi-Fi when possible

This reduces constant signal searching.

10. Replace the Battery (If Necessary)

If your phone is old:

  • Check battery health

  • Replace battery if health is below 80%


A new battery can completely solve overheating issues.

What You Should NOT Do

Avoid these mistakes:

❌ Don’t put phone in freezer
❌ Don’t use cheap chargers
❌ Don’t install “cooling apps”
❌ Don’t ignore overheating warnings

These can damage internal components permanently.

Tips to Prevent Phone Overheating in the Future

  • Use original chargers

  • Avoid long gaming sessions

  • Keep storage space free

  • Restart phone regularly

  • Use dark mode

  • Avoid direct sunlight


Final Thoughts

Phone overheating is not something you should ignore. While it’s often caused by simple habits or settings, long-term overheating can reduce battery life and performance permanently. The good news is that by making small changes—like managing apps, avoiding heavy usage while charging, and keeping your phone updated—you can keep your phone cool and healthy.
