Tear Your iPhone Instantly
The first step is to tear your iPhone apart to prevent overheating instantly. This will cool down its parts in a short time.
Remove Your Phone Case
Removing the case allows your iPhone to cool more efficiently by exposing it to air, which helps dissipate heat faster. Since phone cases trap heat and make them overheat, taking off will release the heat gently, thus cooling the iPhone down.
Change Your Battery
An old or damaged battery can overheat during charging; replacing it can reduce heat generation and improve charging efficiency. You can get your iPhone’s battery changed at any Apple store.
Check Your Adapter and Cable
Using non-certified or damaged charging accessories can cause overheating. If you’re using a third-party charger, switch out the cable. And for optimal safety, always use Apple-certified chargers and cables.
Ensure a Cool Environment for Your iPhone
Charge your iPhone in a cool and shady environment to prevent ambient temperatures from raising internal temperature. The direct sunlight and extreme heat can cause your phone to heat up.
Switch off the Background App Refresh
The background app refresh feature downloads updated information online, even when not using a specific app. Downloading a ton of data can result in heating issues. So, disabling this feature reduces the workload on your iPhone’s processor while charging, which can help keep the device cooler. For this purpose:
- Open your iPhone’s Settings and open General.
- Click Background Refresh and turn it off here.
Decrease CPU Activities
Avoid keeping a lot of apps running, like playing games, watching videos, using video editors, calling people, navigating maps, etc., while your iPhone is charging to reduce heat production.
Toggle on Auto-Brightness
This feature adjusts your screen’s brightness based on the surrounding light, which can help conserve battery life and reduce heat. Too much brightness can cause your iPhone to overheat while charging. Here is how to switch it to automatic mode:
- Go to Settings，and scroll down to the Accessibility option.
- Press Display & Text Size to see the Auto Brightness button. Turn it on.
Set Low Power Mode
If the screen is awake for a long time, you will likely face the iPhone overheating issue. So, activating low power mode reduces overall energy consumption by limiting background activity and automatic downloads, which can help keep your iPhone cool. For this purpose, go to Settings > Battery to turn off the Low Power Mode option.
Stop Processor-Intensive Tasks
To prevent overheating, refrain from using your iPhone for tasks such as video streaming, gaming, or augmented reality apps until the charging is full. This will also protect the lifespan of your iPhone’s battery.
Stop and Remove Apps with Glitches
Faulty apps can cause excessive resource usage, leading to overheating. Identifying and removing these can mitigate the issue. Keep holding any app and tap Remove App > Delete App to remove it permanently from your iPhone.
Turn on Airplane Mode
Airplane mode minimizes your iPhone’s power use by disabling wireless communications, which can significantly reduce heat generation during charging. To do this, open the iPhone’s Control Center and click the airplane icon to turn it on.
Update Apps
Keep your applications up-to-date, as developers often release updates to fix bugs that might solve your iPhone’s overheating issue. Below are the steps:
- From the App Store, click your profile photo.
- Now, scroll to the pending updates. Click Update or Update all.
Upgrade Your iOS
Updating to the latest iOS version can enhance your iPhone’s thermal management capabilities, helping it run cooler while charging. Here is how:
- Open Settings > General > Software Update.
- Click Automatic Updates and turn on Download iOS Updates.
- Also, turn on Install iOS Updates to update the iOS to the latest version.
Reset All Settings
Although resetting all settings is not recommended, try it out if other fixes don’t work. It can help resolve incorrect settings without erasing your data that may be causing your iPhone to overheat.
For this purpose:
- Open Settings and navigate to the General tab.
- Scroll down and click Reset. Press the Reset All Settings option.
DFU Restore
Performing a DFU restore can help fix deep-rooted software issues that cause overheating by completely reinstalling the iPhone’s firmware and software. It will remove all data on your iPhone, so think twice before proceeding.
- Plug your iPhone into a computer and ensure that iTunes or Finder is open.
- Later, press down and release the Volume Down and Volume Up buttons.
- Hold down the Side button until it gets locked. Hold down the Side button until the screen goes black.
