Why is your iPhone battery life plummeting in the cold weather?

There is in fact a scientific reason behind it - and it's not because you're featuring a live feed of your snow-covered back garden on Snapchat.

The lithium-ion battery in iPhones can lose their life quickly in cold temperatures. Within a few minutes, the battery can lose enough power to shut down the device.

Technically, the phone isn't actually discharging. Instead, the lithium-ion battery simply cannot function at extremely cold temperatures, according to Apple Dystopia website.

The lithium-ion battery has many advantages - they're much lighter than other types of rechargeable batteries of the same size, a lot of energy can be stored in the battery and they can handle hundreds of charge/discharge cycles.

However, the batteries are extremely sensitive to both low and high temperatures.

They are at their optimum use between zero degrees Celsius and 35 degrees Celsius.

iPhone users are also advised not to charge the lithium-ion batteries in temperatures below zero degrees Celsius.

Doing so can result in permanent capacity loss in the battery, and this damage can occur even after one "cold-charging" event.

Furthermore, a lithium-ion battery that has been "cold-charged" is not safe to use.

To avoid all of the above, phone users are advised to keep their phone in their pockets when they're out and about, or to use a thermal phone cover.
