Why does phone battery drain faster in cold weather?

On cold winter days you may feel your cell phone battery draining faster than usual. So what is the reason why cell phone batteries often drain faster in cold weather?

Most phones today use lithium-ion batteries. However, this type of battery has the disadvantage that it can explode at high temperatures and its performance will be significantly reduced at low temperatures.

Lithium-ion batteries use chemical reactions to create energy, so in cold temperatures the reactions are less likely to occur or slow down.

Besides, keeping the phone running in cold weather also causes the battery to consume more energy than usual. That is the reason why the phone battery drains faster in cold weather.

Why does my phone battery drain faster than usual in cold weather?

Lithium-ion batteries have two positive and negative poles. When the battery is fully charged, ions concentrate at the positive pole, when the battery is depleted, ions accumulate at the negative pole.

Depending on how cold it is, your battery life will drain quickly or slowly, in some cases it is so cold that the phone can only work for a few minutes after fully charged.

Many tech experts say the best way to keep your battery safe is to turn your phone off in extremely cold weather. If you need to stay in touch, keep your device warm by keeping it in a closed pocket.

In addition, switching your phone to battery saving mode is also an effective way. Besides, using phone cases helps to retain heat better in cold weather.

Note, when the phone temperature is too cold you should not charge the battery.

Above are the causes and solutions for the situation where cold weather causes phone batteries to drain faster. Hopefully this information will be useful to you.
