The iPhone 15 series has been praised for its performance and sleek design, but not everything has been smooth for every user. One of the most common concerns since its release is the iPhone 15 overheating issues. Whether you’re gaming, using 5G, charging, or multitasking, your iPhone 15 might feel unusually hot—sometimes even to the point of discomfort.
In this blog, we’ll break down why your iPhone 15 is heating up, what you can do to cool it down, and when it’s time to seek professional help. If you’re wondering, “Why is my iPhone 15 overheating?”—you’re not alone. Let’s explore the causes and reliable solutions.
Why Is My iPhone 15 Overheating?
Several factors can contribute to iPhone 15 overheating problems, and understanding them is the first step toward a fix.
1. Background App Activity
Many apps continue running in the background, consuming CPU and battery. Heavy apps like Instagram, TikTok, or games like Call of Duty Mobile can spike the phone’s temperature, especially when paired with high brightness or weak Wi-Fi.
2. 5G Connectivity
Yes, 5G is lightning-fast—but it’s also a battery drainer and heat generator. When your iPhone 15 is connected to 5G in a low-signal area, it works harder to maintain a connection, causing it to overheat.
3. Charging While in Use
Using your phone while charging is one of the biggest culprits of heat buildup. Fast charging also generates extra heat, particularly if you’re using third-party or non-certified chargers.
4. iOS Software Bugs
Apple has acknowledged occasional iOS bugs that impact thermal management. If your phone is running hot without a clear reason, check for an iOS update.
Quick Fixes for iPhone 15 Overheating Issues
While some heat is normal during heavy use, it shouldn’t make your iPhone uncomfortable to hold. Here are some proven steps to reduce iPhone 15 overheating:
✅ Close Unnecessary Background Apps
Swipe up from the bottom and close apps you’re not using. Apps like Maps, AR, or high-resolution video editing tools use a lot of processing power.
✅ Turn Off 5G When Not Needed
Head to Settings > Cellular > Cellular Data Options > Voice & Data, and switch to LTE if 5G isn’t required. This simple change can reduce overheating and save battery.
✅ Update to the Latest iOS
Go to Settings > General > Software Update. Apple often patches overheating bugs with system updates. Stay current to ensure better thermal control.
✅ Avoid Using While Charging
Let your phone rest while it charges. Avoid gaming, video calls, or streaming apps like Netflix and YouTube when your iPhone is plugged in.
✅ Remove the Case Temporarily
Some bulky or poorly ventilated cases trap heat. Try removing your case when charging or during intensive tasks.
When to Seek Professional Help
If your iPhone 15 overheating persists despite all your efforts, there could be a deeper hardware issue. Signs that require professional inspection include:
- 🔥 iPhone shuts down due to extreme heat
- 🔋 Rapid battery drain along with overheating
- ⚠️ Overheating after just a few minutes of basic use

Prevent Future iPhone 15 Overheating Issues
Here are a few long-term practices to keep your device cool:
🌞 Avoid Direct Sunlight
Leaving your phone in a car dashboard or under the sun can cause it to overheat quickly. Always store it in a shaded area when outdoors.
🧊 Turn On Low Power Mode
Enable Low Power Mode via Settings or Control Center to reduce background activity and lower heat generation.
💻 Reset Settings if Needed
Go to Settings > General > Transfer or Reset iPhone > Reset All Settings. This won’t erase your data but can fix misconfigured settings causing the issue.
⚙️ Use Only Certified Accessories
Using cheap or third-party chargers can cause voltage inconsistencies, leading to heating. Stick to Apple-certified chargers and cables.
