What to do with the iPhone so that it stops turning off and hangs in the cold

With the onset of cold weather, iPhone users are increasingly complaining about their incorrect work. The phone in the cold begins to slow down, quickly discharges, and sometimes even turns off, leaving its owner without communication with the outside world.



In this article, we will explain why this happens and how to keep the battery longer in the winter.

Strictly speaking, this is not only a problem of Apple devices. The fault of all lithium-ion batteries, which quickly lose their properties in the cold. At negative temperatures, the internal resistance of such a battery increases, and its capacity falls.

According to the recommendations of Apple, the optimal temperature for the iPhone is in the range from 0 to 35 degrees.



So complaining to the service center is useless. The company disclaims responsibility for the operation of the device if it was in low or elevated temperature conditions.

Why do some models suffer more than others? The likelihood of a smartphone shutting down at low temperatures increases as its battery ages chemically. To assess this indicator, the number of recharge cycles and compliance with operating rules are taken into account.



Therefore, if you have been using your iPhone for several years, then an unpleasant problem will come to you more often. Stronger from frost also suffer models with an aluminum case, which has a higher thermal conductivity compared to plastic.

How to extend the iPhone in the cold

1. Charge 100%.
   Yes, at home, 30% of the charge may last you a long time. But if you're going for a winter walk, try to fill up the battery completely.
   
   
   
   As we have already written, smartphones that are more than a year old are not most friendly with the cold. To reduce the likelihood of spontaneous shutdown of such a device in severe frost, the old battery is better replaced with a new one.
   
   
2. Buy a case.
   The case won't heat the phone, of course. But as heat insulation is quite useful. Especially if it is not made of plastic, but of leather or dense fabric.
   
   
   
3. Carrying iPhones in your inner pocket
   It may be banal, but the temperature in the bag and in the inner pocket of the down jacket can be significantly different.
4. Use the headset.
   The less you take the phone out of your pocket, the less it cools in the cold and the less likely it is to discharge. Help voice dial and Apple Watch, on the screen which you can read messages.
   
   
   
5. Bring the Power Bank with you.
   It can be put in a bag or even in a pocket and connected to the phone to prevent it from quickly discharged.
6. Warm your smartphone with a demanding game
   Before leaving the house, you can run any resource-intensive application on the phone. The temperature of the device will rise and cool down later it will be longer.

What to do and what not to do if the iPhone is turned off? To turn on the iPhone discharged in the cold, it must be heated and connected to a power source. But there are nuances. If you act carelessly, you can only harm.



Do not put your smartphone on the battery or even heat it with a hairdryer. With a sharp temperature difference inside the housing can form condensation. And a hair dryer can melt parts from plastic.

It is best if the phone will naturally heat up at room temperature for 20-30 minutes. After that, the charger can be connected. This will prevent damage to the battery and other components of your iPhone.

After turning on the iPhone, conduct a forced hardware overload (Hard Reset), which will reset probable software errors. It's done in three stages. It is necessary to alternately press and release the volume button and the volume button, and then for 10 seconds to press the power button.

We hope our advice will help you. But it may also turn out that a smartphone that has failed in the cold is just an opportunity to look around to understand how much we lose, being buried in its screen all day long.
