What’s Causing the iPhone 15 overheating problem?

Before we dive into the fixes, it’s important to understand what might be causing your iPhone 15 overheating problem in the first place. Here are some of the most common culprits:

Software and App Issues

Problematic apps, iOS bugs, and software crashes can all cause an iPhone 15 to heat up. Apps that use GPS, the camera, or graphics/CPU-intensive functions are more likely to trigger iPhone 15 overheating problem.

Charging and Battery Problems

Using lower-quality cables, chargers, or batteries can lead to overheating during charging. An aging or damaged battery may also have trouble regulating heat.

Hot Environments and Direct Sunlight

Exposing your iPhone to high ambient temperatures or direct sunlight for too long can cause it to warm up excessively. This is especially true if you’re simultaneously using demanding apps.

Dust and Debris Buildup

Pocket lint, dust, and other particles getting lodged in your iPhone’s ports or openings can restrict airflow and cooling inside the device.

Top Solutions To Fix iPhone 15 Overheating Problem

If you suspect one of the common overheating causes listed above applies to your iPhone 15, then try the following troubleshooting tips:

1. Close Apps and Let the iPhone Cool Down

If your iPhone feels extremely hot, stop using it immediately (except for emergency calls) and let it cool off for 30 minutes. Heat can build up faster than it can dissipate, so giving your iPhone 15 time to return to room temperature is essential.

While waiting, you can also force quit any memory-intensive apps that may be contributing to overheating. Double tap the Home button and swipe up on the app previews to close running apps.

2. Move the iPhone Out of Direct Sunlight

As mentioned before, direct sunlight hitting your iPhone 15’s body can really heat it up. If you have been using your phone outdoors on a hot, sunny day, move to a shaded area immediately.

If possible, point a fan at your phone to accelerate cooling. Avoid placing it on heat-trapping surfaces like car seats during this time.

3. Turn On Airplane Mode

Radios like cellular connectivity and Wi-Fi emit electromagnetic radiation that slightly warms phones from the inside. If your iPhone is already bordering on overheated, then every small heat contribution matters.

You can turn on Airplane mode from Control Center to temporarily disable all wireless radios and prevent internal heating. Re-enable radios selectively later as needed.

4. Stop Charging and Use Alternative Charger

It’s important to stop charging immediately if you notice heating up while charging your iPhone 15. Faulty, damaged, or lower-quality charging accessories can overload power regulation chips and lead to thermal runaway.

If possible, switch to an alternative, MFi-certified Lightning cable and 20W USB-C Power Adapter. Also, give your iPhone some cool-down time before resuming charging.

5. Update iOS, Apps, and iPhone Software

Apple and third-party app developers regularly push software updates to fix bugs, improve performance, and address overheating issues.

Head to Settings > General > Software Update to download the latest iOS update. Also update apps, especially those that access GPS, graphics processors, etc which are prone to overheating-related bugs.

6. Check iPhone Ports and Speakers for Blocked Debris

As mentioned before, dust buildup in ports, speakers, and other iPhone openings can block airflow and amplify heat trapping inside.

Use a soft-bristle toothbrush or microfiber cloth to gently clear any visible debris buildup around the Lightning port, earpiece, or speakers. Avoid inserting anything sharp or metal that could damage delicate components.

7. Disable Background App Refresh and Notifications

Restricting battery-draining features like Background App Refresh and superfluous notifications can lower iPhone power consumption, thereby reducing associated heating.

Head to Settings > General > Background App Refresh and toggle off apps that don’t need constant data feeds. Similarly, disable unnecessary Notification Center alerts under Settings > Notifications.

8. Schedule a Genius Bar Appointment

If you have already tried all other troubleshooting tips without success, your iPhone 15 could have a battery or hardware defect causing persistent overheating. Schedule a Genius Bar appointment at the nearest Apple Store for advanced diagnostics and repair options.

Apple Geniuses have specialized tools and processes to accurately pinpoint overheating issues. They can suggest replacing swollen batteries or damaged components contributing to heat. As an Apple-certified repair center, the Genius Bar should be your last resort before considering a warranty replacement.
