iPhone 15 Pro Max Overheating – Fast Fixes You Can Try
If you’ve recently noticed your iPhone 15 or iPhone 15 Pro Max getting unusually hot, you’re not alone. Many users have reported the same issue since the phone’s release — and while Apple has addressed part of the problem with a software update to iOS 17.1.7, some users still face overheating in everyday situations.
At Phone Chek Brampton, we’ve seen firsthand how overheating can affect performance, battery life, and even hardware stability. Let’s explore why this happens, how to cool your iPhone quickly, and how to prevent it from happening again.
Why Is My iPhone 15 or iPhone 15 Pro Max Overheating?
The iPhone 15 series uses Apple’s advanced A17 Pro chip, a powerhouse built for gaming, 4K video, and high-performance tasks. However, several factors can push it beyond its comfort zone.
Here are the four most common causes of overheating:
1. Running Too Many Heavy Apps
If you’re multitasking between gaming, video editing, and social media, the processor works overtime. High-intensity apps like Call of Duty Mobile or Instagram Reels can push the A17 chip to its limits, generating heat in the process.
2. Charging Habits
Using your iPhone while it’s charging, or using cheap, non-certified chargers, can trap heat. Even fast charging builds up temperature when the phone is under load — like streaming or gaming.
3. Hot Environment
Leaving your iPhone inside a car or exposed to direct sunlight can quickly raise its internal temperature. The iPhone is designed to operate within a specific range — once exceeded, it will throttle performance or even shut down to protect components.
4. Dusty or Moist Charging Port
Dust and moisture in the charging port can create electrical resistance and heat. Cleaning the port gently with a soft, dry brush can help prevent short circuits and charging issues.
Top 10 Proven Tips to Fix iPhone 15 Overheating
1. Chill With Less Demanding Activities
High-end games and 3D apps push the CPU and GPU to the limit. If your phone heats up, pause gaming and let it rest. Switching to lighter tasks or reducing playtime helps the processor cool down.
2. Keep It Out of the Sun
Avoid leaving your phone in hot cars or direct sunlight. iPhones are built with a safety threshold — if they exceed it, you’ll see a temperature warning and possible automatic shutdown.
3. Stay Updated
Apple often releases software updates that include thermal management fixes. Go to Settings → General → Software Update to install the latest version. Keeping your iOS up to date can drastically reduce heat issues.
4. Monitor Battery Drainers
Some apps constantly run in the background, using power and generating heat. Check Settings → Battery to find which apps consume the most energy and close or uninstall them if not needed.
5. Use a Thinner Case
Thick or insulated cases trap heat. Try removing the case temporarily or switching to a lightweight, breathable one like an Aramid Fiber Slim Case.
6. Restart Your iPhone Regularly
Restarting helps clear temporary processes that may overwork the CPU. Hold the side button and either volume button, then slide to power off. Wait a minute before turning it back on.
7. Adjust Auto-Lock Settings
Set Auto-Lock to 30 seconds or 1 minute. Keeping your screen active for long periods increases heat generation, especially at high brightness.
8. Limit Frame Rate
You can lower the graphics load by going to Settings → Accessibility → Motion → Limit Frame Rate. This small tweak reduces processing strain during animations and games.
9. Turn Off Auto-Brightness
Go to Settings → Accessibility → Display & Text Size → Auto-Brightness and toggle it off. Manually adjusting brightness can reduce both eye strain and heat buildup.
10. Disable Background App Refresh
Turn off background processes by navigating to Settings → General → Background App Refresh and disabling it. This stops apps from updating constantly when not in use, easing processor load.
Bonus Tip: Avoid Overnight Charging
Although Apple’s optimized battery charging helps, leaving your iPhone plugged in overnight keeps it warm for hours. Unplug once it hits 100%, and use certified Apple or MFi chargers for the best results.
When It Might Be Hardware-Related
If your iPhone still overheats after trying all the above fixes, it could point to a hardware issue — such as a faulty battery, charging IC, or internal sensor. Kernel panic reports in iPhones often log these errors, helping technicians pinpoint the cause.
