iPhone overheating is a common issue during hot summer months, especially in the U.S. and Canada. Excessive heat can slow down performance, reduce battery life, or even temporarily disable your device. This AvNexo guide provides step-by-step tips to prevent your iPhone from overheating and keep it running smoothly.
Common causes of overheating include:
Direct sunlight exposure or hot environments
Running intensive apps like gaming or video editing
High screen brightness
Background processes such as app updates or iCloud syncing
Faulty charging accessories or non-Apple cables
Keep your iPhone out of direct sunlight when outdoors.
Store it in a shaded area, bag, or case with ventilation.
Avoid leaving your phone inside a hot car, which can exceed safe operating temperatures.
AvNexo Tip: Temperatures above 95°F (35°C) can cause iPhone performance throttling or automatic shutdown.
Close or limit apps running heavy graphics (games, AR apps, video streaming).
Turn off Background App Refresh: Settings → General → Background App Refresh → Off.
Pause large downloads or updates during peak heat hours.
Lower screen brightness: Control Center → adjust brightness slider.
Enable Auto-Brightness: Settings → Accessibility → Display & Text Size → Auto-Brightness.
Switch to Dark Mode: Settings → Display & Brightness → Dark. Dark Mode reduces OLED screen heat.
Avoid charging your iPhone under direct sunlight or in hot cars.
Use Apple-certified cables and adapters to prevent excess heat generation.
Consider wireless charging only in cooler, ventilated areas.
Disable Bluetooth, Wi-Fi, or GPS when not in use.
Turn off Location Services for apps that don’t require it: Settings → Privacy → Location Services.
Excessive connectivity can generate heat, especially outdoors in summer.
Low Power Mode reduces CPU load and background tasks, which helps keep your iPhone cooler:
Settings → Battery → Low Power Mode → Toggle On.
This also saves battery during heat waves.
Some cases trap heat:
If your iPhone is overheating, remove the case to allow better airflow.
Only use ventilated or lightweight cases during hot weather.
A temporary software glitch can cause overheating:
Restart iPhone: Settings → General → Shut Down → Power On.
Force restart if unresponsive: Quick volume up → Quick volume down → Press and hold Side button until Apple logo appears.
Keep your iPhone firmware updated: Settings → General → Software Update. Apple includes optimizations to prevent overheating.
Avoid leaving the phone on dashboard mounts in U.S. summer sun.
