3Avoid Sunlight

When it comes to keeping your iPhone 15 cool and comfortable, avoiding direct sunlight is a crucial first step. Just like you wouldn't want to sunbathe in the middle of a scorching heatwave, your iPhone isn't a fan of the sun's embrace either. Prolonged exposure to direct sunlight can lead to your iPhone overheating, and that's a sizzling dilemma we want to avoid.

So, the next time you're enjoying the great outdoors with your trusty device in hand, keep it in the shade or tucked away in your pocket. This simple precaution can go a long way in preventing your iPhone 15 from turning into a pocket-sized oven.

4Remove Phone Case

Your iPhone 15 might be clad in a sturdy protective case, but just like you, it needs to breathe to stay cool. While phone cases are fantastic for shielding your device from drops and dings, they can also inadvertently trap heat, causing your iPhone to overheat.

So, consider giving your iPhone 15 a breather by removing the case when you're not in a high-risk situation for drops or damage. This simple step can help your device dissipate heat more effectively, ensuring it remains at a comfortable temperature.

Remember that not all cases cause overheating, and some are designed to dissipate heat effectively. If your case is specifically causing the overheating issue, you may want to consider using a different case or one with better ventilation. It's essential to strike a balance between protecting your device and ensuring it doesn't overheat.

5Quit Battery-Comsuing Apps

Quitting battery-consuming apps is a crucial step in preventing your iPhone 15 Pro from overheating. Here's how to identify and quit these apps:

    Go to your iPhone's "Settings."

    Scroll down and tap on "Battery."

    You'll see a list of apps and their battery usage over the last 24 hours or the last 10 days.

    Look for apps that have a high percentage of battery usage. These are the apps that are most likely causing your device to overheat.

    To quit a battery-consuming app, swipe up from the bottom of the screen to access the app switcher.

    Find the app you want to quit and swipe it up or off the screen to force quit it.

    In your iPhone's settings, under "General" and then "Background App Refresh," you can choose which apps are allowed to refresh in the background. Limit this feature to essential apps to conserve battery.

    Press and hold on the Lock Screen until you see the "Customize" button.
