Overheating is often a symptom of your device working too hard, or being exposed to conditions beyond its optimal operating temperature range. Identifying the root cause is the first step towards a lasting fix, ensuring you can address the problem effectively rather than just treating the symptoms.
Intensive Usage and Demanding Apps
Running graphics-intensive games, streaming high-definition videos, using GPS navigation for extended periods, or engaging in long video calls can push your iPhone’s processor and Graphics Processing Unit (GPU) to their limits. This increased workload generates significant heat. Furthermore, continuous background app refresh for numerous applications can silently contribute to overheating, even when you’re not actively interacting with the apps, as they constantly fetch new content.
Software Glitches and Outdated Apps
Sometimes, a recent iOS update might introduce temporary bugs that cause excessive power consumption, leading to unexpected overheating. Similarly, outdated applications that haven’t been optimized for the latest iOS version can become inefficient, leading them to demand more resources and thus generate more heat. A continuous loop within an app or a crashed process lurking in the background can also silently drain power and elevate your iPhone’s temperature.
Charging Habits and Accessories
Charging your iPhone, particularly with fast chargers, inherently generates heat. This effect is compounded if you simultaneously use your device for demanding tasks while it’s plugged in. Using non-certified, third-party, or faulty charging cables and power adapters can also lead to inefficient charging, drawing more power than necessary and causing excessive heat buildup, which can be dangerous for both your device and your safety.
Environmental Factors
Exposure to direct sunlight, leaving your iPhone in a hot car, or using it in extremely warm ambient temperatures (such as during a heatwave) are prime culprits for rapid overheating. These external heat sources make it incredibly difficult for your device to dissipate its own internal heat, forcing its temperature to rise quickly beyond safe operating limits.
Hardware Issues and Battery Health
An aging battery with degraded health can become less efficient at holding and delivering a charge, making it more prone to heating up during use or charging cycles. You can check your battery health in Settings > Battery > Battery Health & Charging. In rare instances, internal hardware malfunctions, though less common, can also manifest as persistent overheating, indicating a more serious underlying problem.
Immediate Steps: How to Cool Down an Overheating iPhone Quickly

1. Move Your Phone to a Cooler Environment
This is often the most straightforward and effective first step. If your phone is in direct sunlight, on a dashboard, or in a warm room, immediately relocate it to a cooler, shaded area. An air-conditioned room, placing it near a fan, or simply on a cooler, non-insulating surface (like a wooden table, not cloth or carpet) can help dissipate heat quickly. Absolutely avoid putting it in a refrigerator or freezer, as rapid temperature changes and condensation can cause severe and irreversible internal damage from moisture.
2. Remove Its Case
Many phone cases, especially thick, protective ones made from materials like rubber or silicone, can act as insulators, effectively trapping the heat generated by your iPhone. If your phone feels excessively warm, take off its case to allow for better airflow around the device and facilitate heat dissipation. This simple action can often provide immediate relief and significantly help your device cool down much faster, particularly if the case is snug and doesn’t allow heat to escape easily.
3. Close All Background Applications
Apps running in the background, even if they appear dormant, still consume processor power, utilize data, and consequently generate heat. To manage this, double-tap the home button (for older iPhone models with a physical button) or swipe up from the bottom of the screen and pause (for Face ID models) to access the app switcher. Then, swipe up on all open apps to completely close them. This action reduces the overall workload on your iPhone’s processor and RAM, allowing its internal components to cool more efficiently.
4. Stop Intensive Activities
If you’re currently engaged in demanding tasks such as playing graphics-intensive games, streaming high-definition videos, continuously using GPS navigation, or participating in long video calls, pause or stop these activities immediately. These are some of the most resource-intensive operations your iPhone performs, leading to significant heat generation. Giving your phone a brief respite from these strenuous demands will allow its central processing unit (CPU) and graphics processing unit (GPU) to cool down.
5. Enable Low Power Mode
Low Power Mode, while primarily designed to conserve battery life, also effectively reduces background activity, automatic downloads, and visual effects – all of which contribute to heat generation. By minimizing these power-hungry processes, Low Power Mode helps to lower your iPhone’s temperature quickly. You can easily enable it from the Control Center (swipe down from the top-right corner on Face ID models, or up from the bottom on Home button models) or by navigating to Settings > Battery.
Long-Term Solutions: How to Fix and Prevent Your iPhone From Overheating
Beyond immediate cooling, implementing preventative measures and optimizing your iPhone’s settings can significantly reduce the likelihood of future overheating episodes. These are the “fixes” that address the root causes and promote healthier device operation.
6. Optimize Your Battery Charging Habits
Charging is a common time for iPhones to heat up due to the chemical reactions occurring within the battery. To mitigate this, go to Settings > Battery > Battery Health & Charging, and ensure “Optimized Battery Charging” is enabled. This intelligent feature learns your daily charging routine and delays charging past 80% until just before you typically need your phone, reducing the time your battery spends at peak charge and thus lowering thermal stress. Always use certified Apple or MFi (Made for iPhone) chargers and cables, as non-certified accessories can be inefficient and unsafe. Crucially, avoid using your iPhone for demanding tasks while it’s actively charging, as this compounds heat buildup.
7. Manage Background App Refresh
Many apps continue to update their content in the background even when you’re not actively using them, consuming power and generating heat. You can gain control over this by navigating to Settings > General > Background App Refresh. Consider disabling it entirely if you don’t need real-time updates for many apps, or selectively turning it off for individual apps that don’t require constant synchronization. This significantly reduces unnecessary background activity and overall power consumption, which directly translates to less heat.
8. Keep Your iOS and Apps Updated
While an iOS update can sometimes temporarily cause heating issues as the system settles in, Apple frequently releases updates that include crucial performance improvements and bug fixes. Many of these updates are specifically designed to optimize power efficiency and reduce heat generation. Similarly, keeping your individual apps updated ensures they are running the most optimized, stable, and energy-efficient versions available. Always install updates when prompted, as they often contain critical optimizations for better thermal management.
9. Adjust Location Services and Push Notifications
Apps constantly requesting your location in the background or delivering frequent push notifications can contribute significantly to battery drain and, consequently, overheating. Review your Location Services settings by going to Settings > Privacy & Security > Location Services. Set app access to “While Using” or “Never” for apps where constant location tracking isn isn’t essential. Similarly, manage your push notifications in Settings > Notifications, enabling only essential alerts to prevent your phone from constantly waking up and processing data.
