The iPhone is the most popular smartphone in the world. But there is one problem that every iPhone user has to face at some point or another. That problem is overheating while charging. Often, the iPhone gets hot while charging and the user gets nervous that the phone might get damaged. This issue is a normal issue that everyone faces at some point or another. But if your mobile phone is overheating regularly, then it affects both the mobile and the battery life.

Earlier, my mobile used to overheat while charging. But then I tried some methods through which my mobile no longer gets too hot.

In this article, we will look in detail at why the iPhone overheats while charging, what are its disadvantages, and how we can easily fix it.

Why Does iPhone Overheat While Charging?

1. Background Apps Running

Often people do not close apps while charging their mobile phones. But it is necessary to close these apps because these background apps put extra load on the battery and processor, which increases heating.

2. Using Phone While Charging

Using your mobile phone while charging it, such as watching YouTube, gaming, or scrolling through social media, puts double pressure on the mobile phone, which causes it to overheat.

3. Non-Original Charger or Cable

When charging your mobile phone, using a local charger or cheap cable draws more power, which heats up the iPhone battery.

4. High Ambient Temperature

If you charge your mobile phone in a hot place or in direct sunlight, then overheating is normal.

5. Battery Health Issue

If your iPhone battery is too old or has degraded health, it can also overheat.

Is iPhone Overheating Dangerous?

• The battery life of the iPhone may decrease.
• The charging speed of the iPhone becomes slow.
• Sometimes the mobile stops charging by giving a temperature warning.
• In extreme cases, internal damage may also occur (rare).
• When the iPhone gets too hot, iOS automatically slows down the processor, causing apps to lag.
• Excessive heat can affect the LCD panel, causing the screen color to fade or yellowish spots.
• If your iPhone is constantly overheating, then the battery may be physically swollen.
• Due to overheating, the iPhone shuts down to protect the system.
• Heating may damage the motherboard or charging IC.

10 Easy Fixes for iPhone Overheating While Charging

1. Use Original Apple Charger & Cable

Always use an Apple certified cable (MFi certified) when charging your mobile. It is safe. It avoids overheating.

2. Remove Phone Case While Charging

The thick cases that mobile phones have cover the heat. Therefore, remove the mobile case when charging.

3. Avoid Using Phone During Charging

4. Charge in Cool Place

Do not expose your mobile to the sun while it is charging. Always keep your mobile in a cool place while charging.

5. Close Background Apps

Double-tap the home button on your mobile or swipe up to close all the apps. This will prevent your mobile phone from heating up and will charge faster.

6. Turn on Airplane Mode While Charging

If you never have an urgent need, then charge your mobile phone by putting it on airplane mode. This will charge your mobile phone faster and cooler.

7. Update iOS

Sometimes old software bugs in mobile phones also become the reason for heating. Therefore, keep your iOS latest update installed.

8. Use Optimized Battery Charging Feature

Go to the battery settings in the iPhone settings. Enable optimized charging there. This reduces both mobile heating and battery drain.

9. Don’t Charge Overnight

If you keep your mobile on charge all night, it overheats the mobile. So always try to avoid this.

10. Check Battery Health

Open the iPhone settings, go to the battery option, and check the battery health there. If the health is below 80 percent, then the battery should be replaced.

Bonus Tips to Keep iPhone Cool
