Part 1: Why does iPad or iPhone Turn Off by Itself When It's Cold?

In winter, iPad or iPhone turns off by itself, which is mainly caused by the temperature being too low. Current smartphones use the lithium-ion battery. A too low temperature may affects the speed of chemical reaction. So the battery provides less energy to meet the needs of the iPhone. Sometimes it is believed that the lithium-ion battery discharges more quickly in winter. But in fact, the capacity of lithium-ion battery decreases due to the temperature.

Part 2: What to do When the iOS Device Suddenly Turns Off?

The low temperature is one of the causes for the device turning off. There are other causes. You can try the methods mentioned below to fix this problem.

1. Check the Device Battery after Connecting to Power Adapter

In an environment with a low temperature, the battery displayed on the device is not the actual. Therefore, you can connect your device to the power supply to check the battery.

2. Force Restart iPhone or iPad

When encountering errors on the iPhone or iPad, you can always restart the device. For various iPhone models, the restart steps are different.

· For iPhone 8, 8 Plus, X and later models:

Press the Volume Up button and quickly release it. And then press the Volume Down button and quickly release it. Then hold the side button until the device starts and the Apple logo is displayed.

· For iPhone 7 and 7 Plus:

Keep holding the Power button and the Volume Down button at the same time until the device starts and the Apple logo is displayed.

In addition, for iPad with the Home button , hold the Power button and the Home button at the same time for at least 10 seconds.

For iPad Pro without the Home button, press the Volume Up button and quickly release it. And then press the Volume Down button and quickly release it. Then hold the Power button until the Apple logo appears.

Part 3: Notes for Maintaining iPhone and iPad Battery

It is essential to maintain the battery properly to extend the battery life of iPhone and iPad.

1. Keep Away from Extreme Temperatures

In the daily maintenance of the battery, it is recommended to keep the device in an environment with the temperature between 16 and 22 ° C and to avoid the temperature higher than 35 ° C. When you charge the battery in an environment that exceeds the ideal temperature, the battery can only be charged up to 80%. In an extremely cold environment, you find that the battery discharges too quickly. In fact, this phenomenon is temporary. When the battery temperature returns to the normal temperature range, its performance returns to normal. In addition, if you charge the battery with a protective case, it may cause excessive heat which will affect battery usage. It is therefore recommended to charge the device without the protective case.

2. Keep 50% Battery During Prolonged Storage

If you do not use the device for a long period, the ambient temperature and the percentage of battery charge will influence the performance of the battery. So, you are advised to:

① Do not fully charge or discharge the device. It is better to keep 50% battery on the device. If you store the device with the battery completely discharged, the battery may fall into a state of deep discharge or even it is no longer possible to charge the battery. On the other hand, if you store a iPhone or iPad with the fully charged battery for a long time, the battery capacity and its life will be partially reduced, which will shorten the battery life of iPhone or iPad.

② Switch off the device to avoid battery to drain.

③ Keep the device in a cool, dry environment with the temperature below 32 ° C.

④ Charge the battery at 50% every 6 months if you plan to keep the device for more than 6 months.

The battery is probably weak after a long storage period. To use the device again, you can charge it with the original adapter for 20 minutes.

3. Empty the Battery to 0% Regularly

You can discharge the iPhone or iPad up to 0% battery. The device then switches off. And after, you can charge the device completely to 100% battery.
