Few things are as frustrating as your iPhone 16 overheating when you need it most. Whether you’re trying to take the perfect photo, manage urgent calls, or simply browse the web, excessive heat can disrupt usage, reduce performance, and even shorten your device’s lifespan.
Overheating is common in smartphones, especially during warm weather, intense app usage, or poor charging habits. Fortunately, Apple’s iOS 17 offers smarter performance management and with a few adjustments, you can significantly reduce your iPhone’s chances of overheating.
In this post, we’ll explain the root causes and share five expert-recommended strategies to keep your iPhone 16 running cool and efficiently.
What Causes iPhone 16 to Overheat?
Your iPhone 16 may overheat for a variety of reasons:
-
Running too many apps simultaneously
-
Direct sun exposure or high ambient temperatures
-
Background processes using CPU/GPU cycles
-
Using your phone while charging
-
Software bugs or outdated apps
-
Hardware malfunction, including battery or charging IC issues
Understanding the “why” is key to applying the right fix. Below are five highly effective tips.
1. Keep Your iPhone Out of Heat Traps
Avoid leaving your iPhone in hot environments like on a dashboard, under a pillow, or in direct sunlight. Even for a few minutes, heat can build up quickly.
Pro Tip: If you’re outdoors, consider a ventilated phone mount or a heat-dissipating case. For long sessions, remove the case entirely.
2. Close Background Apps Regularly
Too many open apps stress the processor and memory, which results in increased heat.
-
Double-press the Home button (or swipe up from the bottom of the screen)
-
Swipe away unused apps

3. Keep iOS and Apps Updated
Outdated software may contain bugs that overwork the CPU or GPU. Apple continuously releases performance and thermal efficiency improvements in updates.
Go to:
Settings → General → Software Update
Additionally, make sure apps especially resource-heavy ones are updated to their latest versions.
While you’re at it, you might also want to set Chrome or Firefox as your default browser for potentially more efficient browsing sessions.
4. Avoid Using Your Phone While Charging
Using your iPhone during charging increases thermal load on both the battery and the processor. This combination can accelerate overheating.
Try to:
-
Let it charge uninterrupted in a shaded area
-
Avoid gaming or video calls while plugged in
-
Use certified Lightning cables and original Apple adapters
5. Check for Hardware Damage or Battery Fault
If your iPhone 16 frequently overheats despite these efforts, it may point to a hardware issue:
-
Battery swelling
-
Faulty Taptic Engine
-
Charging port damage
In such cases, visit an Apple Store or authorized service provider. If your device is under warranty or AppleCare+, repairs may be covered.
Bonus: Manage Screen Time and Brightness
Reducing screen brightness can decrease power draw. You can also limit unnecessary notifications and background tasks by customizing Focus Modes.
