At low temperatures, an iPhone may slow down its operation, quickly discharge, and even shut down. However, the worst scenario for the smartphone's battery is the owner's attempts to quickly revive the device and warm it up, which damages the battery even more, according to The Sun.

How to protect iPhone battery

One of the most obvious signs that something is amiss is that your battery life suddenly shortens. This means your iPhone is extremely cold and the battery can't function properly anymore.

Your iPhone may also slow down because the battery can't sustain high performance levels. In extreme situations, your iPhone can turn off entirely.

However, the good news is that battery issues with the iPhone related to cold weather are not permanent.

"Using an iOS or iPadOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause your device to turn off," Apple explains.

The battery's performance will return to normal when it is at a regular temperature. However, high temperatures can permanently shorten the iPhone's battery life.

Apple advises not to use the iPhone at temperatures below -4 degrees Fahrenheit.

What is strictly prohibited for iPhones

To restore the iPhone's functionality, it needs to be warmed up. However, you should not directly apply a source of heat to it.

Apple warns that you should never use an external heat source to revive the iPhone, whether it's cold or even wet.

Instead, the company simply recommends moving the smartphone to a warmer place. For example, you can bring it inside or put it in an inner pocket of your outerwear.

Under no circumstances should you use a hair dryer or heater to heat the iPhone, as you can irreparably damage it.
