You may have seen this notification on your iPhone saying, “Charging On Hold. Charging will resume when iPhone returns to normal temperature.” If this is the first time you have seen this notification, you may have some questions. Now, this notification might make sense to you if your iPhone is in a particularly hot place. However, some users have said that they were just using their iPhones like normal in an air-conditioned place.
Starting with iOS 16, your iPhone notifies you if the temperature has gotten too high or too low. It also stops the charging process to help prevent damage to your phone.
What temperatures are too high or too low for iPhone?
It is generally recommended that you do not use your device if it is too hot or too cold.
When is it too hot or cold to use or charge your iPhone?
- You should not use or charge your device if the temperature is above 35 Celsius or 95 Fahrenheit.
- You should also not use or charge your device if the temperature is below 0 Celsius or 32 Fahrenheit.
If you use your iPhone when the temperatures are too hot or cold, you risk shortening the battery life of the phone.

Why you might see “Charging on Hold” even in a normal temperature environment
There are situations where your iPhone may get very warm even if the temperature around it is not too high. Some activities can make your phone warm or even hot:
- Restoring your iPhone or setting it up for the first time.
- Using games that are resource intensive. This can also happen with some apps (like AR apps) or some iPhone features.
- Using GPS navigation.
- Streaming video.
- Charging wirelessly.
What should you do if you see the “Charging on Hold” message?
If you are seeing this message, you should:
- If you are using your iPhone, stop and lock the screen or turn off the device.
- Move your iPhone to a cooler or warmer place, out of direct sunlight.
If you are getting this message often, and it doesn’t seem right, you may want to consider contacting Apple.
