iPhone Overheating?

iPhone getting uncomfortably hot? Showing a temperature warning? Here's why it happens and how to safely cool it down without damaging your device.

⏱️ 5-15 min 💪 Easy 🌡️ All iPhones

Normal vs. Problem Heat

Normal warm: Slightly warm during charging, gaming, video calls, GPS navigation

Problem hot: Uncomfortable to hold, shows temperature warning, throttles performance, or shuts down

iPhones are designed to operate between 32°F and 95°F (0°C to 35°C). Above that, they'll display a warning and may shut down to protect themselves.

What Causes Overheating

  • Direct sunlight - especially in cars or on dashboards
  • Heavy use - gaming, video recording, AR apps
  • Charging while using - especially with fast chargers
  • Hot environment - above 95°F ambient temperature
  • Thick case - traps heat inside
  • Software issue - runaway process using CPU
  • Battery problem - failing battery generates excess heat

How to Cool Down Your iPhone

1 Move to a Cooler Area

Get your iPhone out of direct sunlight and heat:

  • Move indoors or to shade
  • Never leave iPhone in a parked car
  • Keep away from heat vents and radiators

2 Remove the Case

Cases trap heat. Take it off to let the phone dissipate heat faster through its aluminum/glass body.

3 Stop Charging

If charging, unplug the cable. Charging generates heat, especially fast charging.

4 Close Heavy Apps

Close games, camera, video apps, and anything using intensive processing:

  1. Swipe up and pause (or double-click Home)
  2. Swipe up on app cards to close them

5 Enable Low Power Mode

Reduces performance and background activity:

Settings → Battery → Low Power Mode

6 Turn Off iPhone

If still hot, power off completely:

  1. Hold Side Button + Volume Down
  2. Slide to power off
  3. Let it cool for 15-30 minutes

7 Fan or Air Conditioning

Place iPhone near (not directly in front of) an air conditioner or fan to help it cool faster.

🚫 Never:
  • Put iPhone in freezer or refrigerator (condensation damages internals)
  • Blow directly with compressed air
  • Submerge in water or ice

8 Check for Software Issues

If overheating happens without heavy use:

  1. Check Settings → Battery for apps using high %
  2. Update iOS: Settings → General → Software Update
  3. Force restart: Volume Up → Volume Down → Hold Side Button

Preventing Overheating

  • Don't charge in direct sunlight or hot car
  • Use Apple-certified chargers
  • Remove thick cases when gaming or charging
  • Take breaks during intensive tasks
  • Keep iOS and apps updated
  • Replace aging batteries (they generate more heat)

When It's a Hardware Problem

Get your iPhone checked if:

  • It overheats constantly, even with light use
  • Battery is swelling (back glass or screen lifting)
  • Overheating started after a drop or water exposure
  • You smell burning or see smoke (stop using immediately!)
⚠️ Swollen battery: If your screen or back is lifting away from the frame, stop using your iPhone immediately. A swollen battery is a fire risk.

iPhone Still Overheating?

If your iPhone keeps overheating despite trying everything, it may have a hardware issue like a failing battery.
