The external environment is the primary factor. The ideal operating temperature range for an iPhone is 0°C to 35°C. Placing the device in a car exposed to direct sunlight, using navigation, or taking photos outdoors in hot conditions for extended periods can quickly exceed this temperature threshold. Alternatively, a thick, poorly ventilated phone case can act like a blanket, hindering heat dissipation.
Internal usage load represents another major heat source. Running demanding games, editing videos, or utilizing augmented reality apps causes the processor and graphics processor to operate at full capacity, generating significant heat.
Simultaneously charging wirelessly while using the phone. A "charge-and-use" scenario - combines battery heat with processor heat, greatly increasing the risk of the iPhone getting hot.
System software issues also warrant attention. Outdated iOS versions may contain power-optimization bugs, while newer releases like iOS 26 temporarily increase resource consumption during initial updates due to background indexing and adaptive learning processes.

Rapid but Short-lived Cooling to Avoid a Hot iPhone
If your iPhone gets too hot to handle, the most direct solution is to cool it down by stopping it from launching. Immediately reduce its temperature and workload by removing the protective case, pausing use, closing apps that consume significant background resources, and so on.
Step 1Go to "Settings", find "General", tap "Background App Refresh", and completely close or exit high-energy-consuming apps.
Step 2Swipe down from the top of the screen. For iPhone 8 and earlier models, swipe up from the bottom.
Step 3After opening Control Center, locate "Low Power Mode" and tap to turn it on. Or you can use Siri to help you open it.
Optimize iPhone System Settings to Reduce a Hot iPhone
Many system-level effects and features, while convenient, can cause hidden heat buildup. Adjusting these settings can significantly reduce energy consumption during daily iPhone use, thereby minimizing the iPhone's getting hot. You can use the following three methods to reduce the issue of the iPhone getting hot caused by system settings.
Step 1Go to "Settings", find "General", tap "Background App Refresh", and completely close or exit high-energy-consuming apps.
Step 2Go to "Settings", find "Privacy & Security" and "Location Services". Review the app list and find rarely used apps.
Step 3Change permissions for apps that don't need location access to "While Using the App" or "Never".
Step 4Go to "Settings", tap "Battery" and "Battery Health". Check if "Maximum Capacity" is below 85%, and consider replacing the battery to avoid the iPhone getting hot.
Use Charging Accessories Correctly to Prevent Overheating
Improper charging methods and accessories pose a high risk of the iPhone getting hot, or even cause the iPhone to not charge in the summer. Therefore, always use Apple genuine or MFi-certified chargers and cables. Uncertified, low-cost accessories may deliver unstable voltage and current, making them highly prone to causing overheating during charging.
Second, avoid using your device while charging. The battery itself generates heat during charging. If you simultaneously play games or watch videos, the heat produced by the processor adds to the battery's heat.
Optimize your charging environment by avoiding charging on soft, insulating surfaces like beds or couches. It's best to charge on a hard, cool surface like a desk and ensure the area is well-ventilated.

iPhone getting hot is often caused by multiple factors. After initial cooling, you can use 4Easysoft iOS System Recovery for a deep scan and repair to prevent prolonged use in overheated conditions.
