What Causes iPhone 15 Overheating?
- Extreme Temperatures: Avoid using your iPhone in temperature extremes outside the recommended range of 0º to 35º C (32º to 95º F) as it can harm the battery and internal components.
- Faulty or Incompatible Chargers: Stick to official Apple accessories or certified third-party chargers to prevent overheating or related issues during charging.
- Intensive or Buggy Apps: Keep an eye on apps that consume excessive CPU, GPU, or network resources, leading to overheating and battery drain. Regularly update and monitor app battery usage to mitigate these problems.
- Outdated or Corrupted Software: Overheating can result from software issues like outdated iOS versions, problematic updates, or malware. Always update to the latest iOS version and regularly scan for malware to maintain optimal performance.
How to Prevent iPhone 15 Overheating?
To prevent your iPhone 15 from overheating, you should follow these tips:
- Temperature Awareness: Avoid exposing your iPhone to extreme temperatures, direct sunlight, or cold environments. Never leave it in a hot parked car, as the interior temperature can exceed safe limits.
- Charger Caution: Use official Apple accessories or certified third-party chargers to avoid potential damage or overheating. Refrain from using cheap or damaged chargers and avoid using your iPhone while it’s charging to minimize heat generation.
- App Management: Close unused apps running in the background as they can drain battery and CPU power, leading to overheating. Swipe them up from the app switcher and consider disabling background app refresh to conserve battery and prevent overheating.
- Optimize Settings: Adjust settings to reduce your iPhone’s workload. Lower screen brightness, disable Bluetooth and Wi-Fi when not in use, activate low power mode, and reduce video resolution to save battery and minimize heat generation.
Check Battery Health
For those who have been using their iPhone for a while, it’s important to keep an eye on the health of your battery. Over time, the battery’s performance can decline, and you might find that it can hold only around 70% or even less of its original capacity. This is a natural occurrence for all lithium-ion batteries, as they lose capacity with each charging cycle.

Here’s how you can check your iPhone’s battery health:
- Open the Settings app on your iPhone.
- Scroll down and select the “Battery” option.
- Tap on “Battery Health” to view the maximum battery capacity.
If you notice that your maximum battery capacity is below 70%, it’s a sign that your battery is not performing at its best. In such cases, you should consider replacing the old battery with a new one. You can do this either at an Apple store or at a reputable third-party service center.
Enable Optimized Charging
When you turn on the “Optimized Charging” feature, your iPhone will sometimes limit its charging to 80% to help prolong the life of the battery. This is done to improve the overall longevity of your iPhone’s battery.

Here’s how to enable “Optimized Battery Charging”:
- Open the Settings app on your iPhone.
- Scroll down and select “Battery.”
- Tap on “Battery Health.”
- Find the option for “Optimized Battery Charging” and turn it on from the menu that appears.

Disable Background App Refresh
If you’ve allowed apps like OneDrive and Google Photos to refresh themselves in the background, they will keep updating with new photos and videos even when you’re not actively using them.
This can be a problem if you have a slow internet connection or limited bandwidth, as it can lead to longer upload times and may cause your device to overheat.

To stop this from happening, follow these steps:
- Open your iPhone’s Settings.
- Scroll down and find either “OneDrive” or “Google Photos,” depending on which app you want to adjust.
- Look for the option that says, “Background App Refresh” and switch it off. This will prevent the app from updating itself in the background.
