iPhone Behavior Beyond The Intended Operating Temperature

In this article, we want to explain what the intended iPhone operating temperatures are and at which temperatures you shouldn’t use your iPhone anymore. In addition, you will learn in what situations it is normal that your iPhone is warmer. We will give you indicators to determine an overheating of your iPhone. In a nutshell, we will focus on the iPhone use within the intended operating temperature.

Ideal temperature for iPhones

First of all, it’s necessary to know what temperatures are the best to operate an iPhone and what temperatures are good for storing iPhones or having it on standby.

Temperature range for usage

Apple officially indicates a temperature range of 32°F (0°C) to 95°F (35°C) for operating an iPhone (and other iOS devices).

If you are using your iPhones beyond these temperatures, it can happen that they change their behavior to regulate the temperature. In this case, they could work slower or shut down completely.

Temperature range for storing

If you are not using your iPhone at the moment, but store it somewhere (doesn’t matter if it is off or standby), the ideal temperature range is between -4°F (-20°C) and 113°F (45°C). Therefore, it can be significantly hotter/colder when you are not using your iPhone than while you are using it.

In this context, it is important that you don’t leave your iPhone in the car when it is extremely hot outside (e.g. in summer), because the temperatures inside the car can be even higher than 113°F.

iPhone gets warm

If your iPhone gets warm, especially in the area around the camera on the back, you generally don’t have to worry. It is normal that your iPhone is warm in the following situations:

  • The iPhone is charging.
  • You are setting up your iPhone for the first time.
  • You are restoring your iPhone from a backup.
  • Apps analyze or indicate data (e.g. Photos app).

iPhone gets too warm

If you left your iPhone in the car on hot days or exposed it to direct sunlight while using it e.g. for GPS, it can happen that your iPhone gets too warm. In this case, you can still use it, but you will notice some changes in the functionality because your iPhone tries to regulate the temperature at the same time:

  • Your iPhone doesn’t charge further or anymore.
  • The display becomes darker or turns off.
  • The cell phone signal is weaker.
  • You cannot use the camera flash.
  • While using the iPhone for GPS, the routing keeps running in the background but the display turned off.

iPhone gets hot

If your iPhone reaches the temperature limit, you will see a warning on the screen of your iPhone and you cannot use the iPhone until it’s cooled down.
