What Causes iPhone 15 Overheating?

There are a few potential culprits that can cause your iPhone 15 to overheat:

  • Using resource-intensive apps or features: Apps and features that use a lot of processing power, like gaming, augmented reality, or video editing/streaming can heat up your iPhone. This is especially true if using these apps for prolonged periods.
  • Direct sunlight or hot environments: Leaving your iPhone 15 in direct sunlight or environments over 95°F can cause Fix iPhone 15 overheating Problem. The heat builds up faster than your iPhone can dissipate it.
  • Charging: Fast charging generates heat. Using an unapproved third-party charger may also lead to overheating.
  • Background tasks and updates: Software updates, iCloud backups, and other background tasks can spike CPU usage, leading to overheating.
  • Hardware defects: In rare cases, a hardware defect like a faulty battery may be the culprit.

While some heat is normal, prolonged overheating can degrade battery life and performance. If your iPhone 15 feels uncomfortably hot, it’s time to try some troubleshooting steps.

1. Turn on Low Power Mode

Low Power Mode is an easy first step to cooling down your overheating iPhone 15. Low Power Mode reduces background activity, performance, and some visual effects to conserve battery life.

Follow these steps to turn it on:

Step#1. Open the Settings app.

Step#2. Tap on Battery.

Step#3. Toggle on Low Power Mode.

Your iPhone will now limit background refresh, auto-downloads, and more. This reduces processor workload and can help prevent overheating. Low Power Mode will stay on until you manually turn it off.

2. Avoid Direct Sunlight and Hot Areas

Keeping your iPhone 15 in direct sunlight or environments over 95°F can rapidly heat it up beyond a safe operating temperature. Here are some tips:

  • Don’t leave your iPhone 15 in a hot car on a sunny day. Interior car temperatures can exceed 120°F quickly.
  • Avoid prolonged sun exposure when using your phone outdoors. Seek shade when possible.
  • Do not place your iPhone 15 in confined, poorly ventilated spaces where heat can rapidly buildup.
  • Be careful with outdoor use in hot climates and switch to Low Power Mode if overheating occurs.

Simply keeping your iPhone 15 out of hot areas can work wonders for reducing overheating issues.

3. Close Resource-Intensive Apps and Features

Apps and features that tax the iPhone 15’s processor are common overheating culprits. If you notice overheating when using certain apps or features, consider the following:

  • Gaming: New 3D games utilize powerful graphics processors that can heat up the iPhone 15, especially at higher quality settings. Close the game and give your iPhone a chance to cool off.
  • Augmented reality apps: AR apps like Snapchat lenses use the camera and sensors intensively. Close these apps if your iPhone gets too hot.
  • Recording/streaming video: Recording 4K video requires major processing power. Stop recording if overheating occurs.
  • Navigation apps: Navigation apps with real-time traffic updates use more resources. Try closing the app when not actively navigating.

By monitoring which apps and features cause overheating and limiting their use, you can better prevent iPhone 15 overheating issues.

4. Update to the Latest iOS Version

Apple continuously releases software updates to fix bugs and optimize performance. Updating to the latest iOS version can help fix overheating problems.

Here are the steps to update your iPhone 15’s iOS version:

  1. Open the Settings app.
  2. Tap General, then Software Update.
  3. Tap Download and Install to update your iPhone to the latest iOS version.

If a new update is available, install it and see if it resolves any overheating issues. The latest iOS 16 update specifically targeted fixing the overheating problem on iPhone 15 Pro models. Keep your iPhone’s software up-to-date for the best performance and heating optimizations.

5. Use a Fan or Cooling Accessory

Using an external fan or cooling accessory can provide added airflow to help cool down an overheating iPhone 15. Here are some options:

  • Cooling fan cases: Cases with built-in fans direct air towards your iPhone, dispersing heat. These cases are powered by internal batteries.
  • Vent mounts: Car vent mounts with integrated cooling fans direct air conditioning at your phone, keeping it cool in the car.
  • Cooling pads: These pads or stands have built-in fans and are designed to direct ambient air at your phone to lower its temperature.

While not mandatory, external cooling accessories can provide an extra level of heat dissipation for an overheating iPhone. They are useful for long gaming or navigation sessions.

6. Disable Background App Refresh

Background App Refresh allows apps to refresh their content in the background when not actively in use. While convenient, this can spike CPU usage and contribute to overheating.

Disabling Background App Refresh can provide a quick fix if overheating is isolated to times when your phone should be idle. Here are the steps:

  1. Go to Settings > General > Background App Refresh.
  2. Tap Background App Refresh to Off.

This will stop non-active apps from running behind the scenes, reducing workload and overheating potential. You can also disable Background App Refresh for individual apps.

7. Turn Off Widget Auto-Update

The widgets on your iPhone 15 Home Screen provide at-a-glance information from apps. However, some widgets auto-update by continuously running in the background. This can cause unnecessary workload if you have many dynamic widgets.

To potentially improve overheating, turn off widget auto-updates:

  1. Long-press on a widget to enter “jiggle” mode.
  2. Look for the switch next to Auto-Update and disable it.

Repeat this for other widgets that dynamically refresh. While widgets won’t update as frequently, it reduces behind-the-scenes workload on your iPhone.

8. Restrict Location Services

Apps that actively leverage your iPhone’s GPS and location services can contribute to battery drain and overheating issues. Consider limiting location access:

  1. Go to Settings > Privacy > Location Services.
  2. Review the list of apps using your location and toggle off access for apps that don’t need it.

You can also select individual apps and restrict location access to While Using instead of Always. Limit location services to reduce CPU workload and overheating when the info isn’t actively needed.

9. Check for Third-Party App Issues

Problematic third party apps can sometimes cause isolated overheating on iPhones. Try these troubleshooting steps related to apps:

  • Update apps: Make sure all apps are updated to their latest version which may contain heating optimizations.
  • Delete unused apps: Remove old and unused apps to reduce background tasks.
  • Uninstall suspect apps: If you notice overheating when using certain new apps, try uninstalling and using your iPhone normally to see if it was the culprit.
  • Hard reset: Perform a hard reset by quickly pressing volume up, volume down, then hold the side button. This will wipe any glitches causing overheating.

Monitoring app issues diligently can help you pinpoint whether a third-party app is the cause of rapid iPhone 15 overheating.

10. Avoid Overcharging

While it’s advisable to keep your iPhone battery between 30–80% charge, constantly charging to 100% can contribute to battery aging over time due to heat buildup.

Follow these tips to avoid overcharging:

  • Stop charging once your iPhone 15 reaches 80–90%. Unplug sooner in hot environments.
  • Avoid using fast chargers unnecessarily. Slow 5W chargers put out less heat.
  • Disable Optimized Battery Charging if not needed. This purposely charges to 100% at times.
  • Use Low Power mode to limit background activity during lengthy charges.
  • Don’t use your iPhone 15 intensively while fast charging due to combined heat.

By being mindful of charging habits, you can moderate heat generation and extend your iPhone 15’s long term battery lifespan.

11. Check for Hardware or Battery Issues

In rare cases, persistent iPhone 15 overheating may be caused by a hardware defect or degraded battery requiring service or replacement. Some signs pointing to hardware issues:

  • Overheating occurs regardless of activity or environment.
  • Your iPhone feels abnormally hot while charging.
  • You notice swelling or deformities near the battery area.
  • Performance is slow or apps crash frequently.
  • Battery life has deteriorated significantly.

If you suspect a battery or hardware problem based on these factors, contact Apple Support. They can run diagnostics, check battery health, and determine if a repair or replacement is needed. Catching hardware issues early prevents bigger problems.
