An overheating iPhone can be frustrating and even alarming—especially when it becomes too hot to hold, drains battery rapidly, slows down, or displays a temperature warning. While occasional warmth is normal during intensive use or charging, excessive or frequent heat can impact performance, reduce battery life, and potentially damage internal components.

In this guide, we’ll cover why your iPhone might be overheating, what you should do immediately to cool it down, and long-term solutions to prevent future overheating episodes.
🌡️ What Causes iPhones to Overheat?
Your iPhone generates heat whenever its processor (CPU/GPU), battery, or display is under heavy load. Common heat triggers include:
- Gaming or video streaming for long periods
- Charging while using the phone
- Background app activity
- Poorly optimized apps
- Exposure to hot environments or direct sunlight
- Wireless charging with limited ventilation
- Using non-certified chargers
Occasional warmth is expected. However, if your phone becomes too hot to touch or shows a “Temperature: iPhone needs to cool down” message, action is required.
✅ Immediate Steps to Cool Down an Overheating iPhone
If your iPhone feels hot or displays a temperature alert, do the following:
Stop Using the Phone Immediately
Exit apps, lock the screen, and stop any active tasks like gaming, GPS navigation, video calls, or streaming.
Move to a Cooler Environment
Take your iPhone indoors or into shade. Avoid sunlight, parked cars, or rooms without ventilation.
Remove the Phone Case
Some cases trap heat, especially rugged or rubberized ones. Removing the case helps dissipate heat faster.
Unplug the Charger
Charging adds to the internal temperature. If your phone is overheating while plugged in, disconnect the cable right away.
Close Background Apps
Swipe up (or double-press the Home button) to access the app switcher and swipe away all unused apps.
Power Off the iPhone
Turning the phone off stops all processes and helps it cool more effectively:
- Hold the Side button + Volume button, then slide to power off
⚠️ Never place your iPhone in the refrigerator or freezer. Rapid temperature changes can cause condensation and internal damage.
🧠 How to Prevent iPhone Overheating in the Future
Cooling it down is just the first step. Here’s how to avoid repeated overheating going forward:
🔋 Avoid Charging While in Use
Using your iPhone for games, FaceTime, or YouTube while charging produces heat from both the battery and processor.
Tip: Let your iPhone charge while idle, and don’t place it under a pillow or blanket during charging.
🕹️Limit High-Performance Apps
Apps like:
- Mobile games with heavy graphics
- AR and 3D rendering apps
- Video editing software
…can heat your phone quickly. Limit usage time and close other apps while running such programs.
⚙️Enable Low Power Mode
This reduces background tasks, mail fetch, and visual effects—lessening heat buildup.
Go to:
Settings > Battery > Low Power Mode
🔧 Turn Off Unnecessary Features
Disable unused services to reduce processor strain:
- Bluetooth
- Wi-Fi (when not needed)
- Location Services for non-essential apps:
Settings > Privacy > Location Services
📶Avoid Poor Signal Areas
Your iPhone heats up trying to find or maintain a weak cellular signal. If possible, switch to Airplane Mode in poor coverage zones to reduce strain.
🔄Update iOS and Apps
Outdated software or apps may have bugs that overload your CPU.
Update Steps:
- iOS: Settings > General > Software Update
- Apps: App Store > Tap Profile > Update All
🧼Disable Background App Refresh
Apps updating in the background add to heat. Turn off this feature unless essential.
Go to:
Settings > General > Background App Refresh > Off
🛑Don’t Use Non-Certified Chargers
Cheap chargers may overheat your device or cause long-term damage. Always use Apple-certified accessories (MFi-certified).
🌤️Avoid Direct Sunlight
Never use or leave your iPhone exposed to direct sunlight, especially on car dashboards or windowsills.
🧪 What Happens When an iPhone Overheats?
If the iPhone becomes too hot, iOS automatically:
- Slows processor speed
- Reduces screen brightness
- Temporarily disables flash and camera
- Pauses charging
- May show a temperature alert and restrict use
These measures protect your device until it cools down.
🆘 When to Contact Apple Support
Reach out to https://support.apple.comor visit an Apple Store if:
- The iPhone frequently overheats, even during light use
- You receive repeated temperature warnings
- Battery drains unusually fast while idle
- Your phone feels hot while turned off or in standby
- The battery is swollen or screen appears lifted
These may indicate a hardware or battery problem that needs diagnosis.
✅ Summary: Fixing and Preventing iPhone Overheating
While occasional warmth is normal, frequent or intense overheating should not be ignored. Taking proactive steps to cool your iPhone and change your usage habits can help maintain performance and extend device life.
