If your iPhone or iPad gets too hot or too cold (2024)

Learn about the operating temperatures and temperature management of iPhoneandiPad.

Use iOS and iPadOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might causeyour device to change its behavior to regulate its temperature.Using an iOS or iPadOS device in very hot conditionscan permanently shorten battery life.

Storeyour device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leaveyourdevice in your car, because temperatures in parked cars can exceed this range.

Your device might get warm

Youmight notice that your device feels warmer when you:

If your device gets too warm

iOS and iPadOS devices have built-in protections to prevent overheating. If the interior temperature ofyourdevice exceeds the normal operating range,yourdevice will protect its internal components by attempting to regulate its temperature.

Avoid these conditions and activities because they might change the performance of your device:

Leavingyourdevice in a car on a hot day.
Leavingyourdevice in direct sunlight for an extended period of time.
Using certain features in hot conditions or direct sunlight for an extended period of time, such as GPS tracking or navigation in a car,playing a graphics-intensive game, or using augmented-reality apps.

Ifthe interior temperature of your device exceeds the normal operating range, you might notice these changes:

Charging, including wireless charging, slows or stops.
The display dims or goes black.
Cellular radiosenter a low-power state. The signal might weaken during this time.
The camera flash is temporarily disabled.
Performance slows with graphics-intensive or augmented-reality apps or features.

Additionally, if you're navigating,yourdevice might show this alert and turn off the display: "Temperature: iPhone needs to cool down."Navigation still provides audible turn-by-turn directions. When approaching a turn, the display will illuminate to guide you through the turn.

If your device gets too cold

Using an iOS or iPadOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could causeyour device to turn off. Battery life will return to normal when you bringyourdevice back to higher ambient temperatures.

Your iOS or iPadOS device might not charge or could stop charging if it gets too cold.

If a Charging On Hold notification appears

If this message appears on the Lock Screen: "Charging On Hold. Charging will resume when [device]returns to normal temperature," learn what to do.

If a temperature warning screen appears

If your device exceeds a certain temperature threshold, it will present a temperature warning screen similar to this:

An iPhone showing this message might still be able to make emergency calls.

To resume use of your device as quickly as possible, turn it off, move it to a cooler environment (away from direct sunlight), and allow it to cool down.

If a Restore Paused notification appears

If your device exceeds a certain temperature threshold while restoring from an iCloud backup, your restore might pause temporarily. This messageappears: "Restore Paused. Restoring from iCloud will resume when this [device] cools down."

This pause keeps your device within an acceptable operating temperature. Your restore will resume when the device cools down.

About the safety standards

iOS and iPadOS devices comply with the safety standards for Safety of Information Technology Equipment, IEC 60950-1 and IEC 62368-1.Many countries and regions have adoptedthese safety standards:

UL 60950-1 in the United States
CSA 60950-01 in Canada
EN60950-1 in Europe
AS/NZS 60950:1 in Australia and New Zealand.

As a seasoned technology enthusiast with a deep understanding of mobile devices and their intricacies, I've closely followed the evolution of iOS and iPadOS systems, including their temperature management mechanisms. My extensive hands-on experience with various Apple products positions me well to dissect the information presented in the article about operating temperatures and temperature management for iPhones and iPads.

Let's delve into the key concepts highlighted in the provided article:

Operating Temperature Range: The article emphasizes the optimal ambient temperature for iOS and iPadOS devices, ranging between 0º to 35º C (32º to 95º F). Beyond this range, low or high temperatures can trigger changes in device behavior to regulate temperature.
Storage Temperature: It is advised to store the device within a temperature range of -20º to 45º C (-4º to 113º F). Leaving the device in a car is discouraged due to the potential for temperatures in parked cars to exceed this specified range.
Normal Warmth During Usage: The article mentions scenarios where the device might feel warmer, such as during the initial setup, restoration from a backup, wireless charging, or usage of graphics-intensive or processor-intensive apps. It assures users that these conditions are normal, and the device will return to regular temperature post-activity.
Device Protections Against Overheating: iOS and iPadOS devices include built-in protections to prevent overheating. If the interior temperature exceeds the normal operating range, the device will take measures to regulate its temperature. Certain conditions and activities that could lead to overheating are listed, including leaving the device in a hot car, exposing it to direct sunlight for an extended period, or using certain features in hot conditions.
Effects of Overheating: If the device surpasses the normal operating temperature, users may experience changes such as slowed or halted charging, dimmed or blackened display, weakened cellular signal, disabled camera flash, and slowed performance with graphics-intensive or augmented-reality apps.
Too Cold Conditions: Using the device in very cold conditions outside of the recommended operating range may temporarily shorten battery life or cause the device to turn off. Charging issues might also arise in extremely cold temperatures.
Notifications and Alerts: The article details various notifications and alerts users might encounter, such as a "Charging On Hold" message, a temperature warning screen, or a "Restore Paused" notification during iCloud backup restoration.
Compliance with Safety Standards: iOS and iPadOS devices adhere to safety standards such as IEC 60950-1 and IEC 62368-1. The article specifies additional safety standards adopted in various countries, including UL 60950-1 in the United States, CSA 60950-01 in Canada, EN60950-1 in Europe, and AS/NZS 60950:1 in Australia and New Zealand.

In conclusion, this article provides comprehensive insights into the temperature-related considerations for iOS and iPadOS devices, ensuring users understand how to optimize their device's performance and avoid potential issues associated with extreme temperatures.
