pple has warned users of its flagship iPhone and iPad devices to beware of extreme, super hot and super cold, weather conditions.
TheNewsGuru.com (TNG) reports Apple gave the warning in a post published on it’s website.
According to the publication, using an iOS or iPadOS device in very hot conditions can permanently shorten battery life.
It advised users not to store their devices where the temperature is between -20º and 45º C (-4º to 113º F).
It also advised users not to leave their devices in their cars, stressing that temperatures in parked cars can exceed this range.
“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 cause the device to change its behavior to regulate its temperature,” the website post reads.
Why your device might get warm
You might notice that your device feels warmer when you:
- Set up your device the first time
- Restore from a backup
- Wirelessly charge your device
- Use graphics-intensive or processor-intensive apps, games, or features, including augmented-reality apps
- Stream high-quality video
These conditions are normal, and your device will return to a regular temperature when the process is complete or when you finish your activity. If your device doesn’t display a temperature warning, you can keep using your device.
When your device gets too warm
iOS and iPadOS devices have built-in protections to prevent overheating. If the interior temperature of the device exceeds the normal operating range, the device will protect its internal components by attempting to regulate its temperature. Here are some of the higher ambient-temperature conditions and activities to avoid, because they might cause the device to change performance and behavior:
- Avoid leaving the device in a car on a hot day
- Avoid leaving the device in direct sunlight for an extended period of time
- Avoid 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
If the 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 radios enter 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, the device 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.
When 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 cause the device to turn off. Battery life will return to normal when you bring the device back to higher ambient temperatures.
Your iOS or iPadOS device might not charge or could stop charging if it gets too cold.
When you see a temperature warning screen
If the 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.
