Why iPhone shuts down in the cold

Why the iPhone shuts down in the cold and what to do in such cases?

You’ve probably heard from friends or have had cases where the iPhone turned off in the cold and then refused to turn on for a long time. Why does the iPhone shuts down in the cold, and how to avoid shutting down your smartphone later, I’ll tell you in this article.

There might be several reasons why iPhone gets turned off on cold weather. The main reason why iPhone does not work well or shuts down in cold weather is the battery. The fact is that at 0°C and below, the ions in the lithium-ion batteries quickly lose their properties. As a result the internal resistance increases and the iPhone battery loses its capacity. Because of this loss of capacity in cold weather, the iPhone shuts down, even if the percentage of charge in the smartphone is still quite high.

iPhone shuts down and refuses to turn back on

Using your iPhone or iPad at low temperatures (below 0°C) may temporarily reduce battery life. As soon as the temperature returns to normal, the battery performance will return to its previous level.

Nevertheless, despite the fact that at low temperatures, the communicator signals a decrease in charge, it remains the same. The fact that in the cold the density of the gel-electrolyte in the battery of the device changes, which affects the speed and quality of the gadget. At the same time, the battery controller detects changes and recognizes them as a loss of charge, which is followed by automatic shutdown of the smartphone.

Apple says the ideal operating temperature for the iPhone and iPad is between 16 and 22 degrees Celsius.

Frost also affects the performance of touch displays. When the device freezes, the screen starts to “slow down” noticeably. Only AMOLED displays are not strictly dependent on ambient temperature.

Unlike Apple, which has strictly regulated the ideal temperature range for working with their gadgets, outside of which the device can lose its guaranteed service, the competitors do not impose the same rigid frame. Thus, gadgets from a number of manufacturers work smoothly at lower temperatures.10 °C. But it should be understood that the limitations of the “Apple” company are dictated not by the flaws in the technology used, but by the notorious desire to create ultrathin smartphones and tablets. Reducing the thickness of devices affects their performance at low (below zero) or high (above 35°C) temperatures.

Nevertheless it is realistic to avoid problems in using the smartphone even in conditions of severe frost. To do this you must understand that for a long time the device will not work outdoors, so you should limit the time of interaction with it as much as possible. It is also desirable to carry your smartphone in a warm inner or in a case. Even the simplest silicone case can significantly extend the life of the gadget. The best option would be to buy a thick felt case for the iPhone communicator, which will protect the device from the undesirable effects of being in low temperature conditions.

Also can contribute to prolonging the working time of the “Apple” communicator is running a resource-intensive program or game in the background mode, which will increase the temperature of the microchip and, consequently, will affect the overall temperature of the gadget.

But what should you do if your iPhone is out in the cold and shuts down?? First of all, remember that it is extremely undesirable to dry it and connect it to the charger. It is better to leave it in a warm room for 1-2 hours. During this time, the gel in the battery will return to its original state and the condensate will dry out.

If you have an irresistible desire to recharge your frozen gadget, you should be aware that a sharp temperature drop can cause deformation and depressurization of the smartphone and further fire or explosion of the device due to the reaction of lithium and oxygen. The loss from such an incident will not be paid by Apple, because as it has already been mentioned above, the company declines all responsibility for the device, if it was exposed to low or high temperatures.

What to do if the iPhone shuts down in the cold

Since the ambient temperature range for iPhone and other Apple products running iOS is 0°C to 35°C, we recommend that you wear your smartphone closer to your body, for example, in your jeans Human heat will maintain the necessary temperature and the battery will not run out before time. Pull out the smartphone only when necessary and for short periods of time, and to make calls, use headphones or other headsets.

If your iPhone does power down, place it in a comfortable environment and wait 20-30 minutes for it to warm up. If after the specified time the low battery icon is still displayed on the screen when you try to turn it on, it means you need to recharge it.

Lithium-ion batteries will last longer if they are not completely drained. They have no memory effect, so try to recharge your iPhone as soon as the battery reaches 10-20 percent.

Also recommend using a case, and do not necessarily buy expensive with an extra battery. Suitable bumper, case or pouch. it will serve as an additional degree of protection against the cold.

But the best solution in our opinion is to buy an external battery. For example, the capacity of 10000 mAh of Xiaomi Power Bank, a review of which is published on our website, enough to recharge the iPhone 7 to 100 percent at least 4 times. But the main thing is that by connecting a portable battery, you can use your smartphone without fear of frost. Xiaomi Power Bank is sold on the following sites:

If the issue is extremely acute, consider replacing the battery. Yes, this procedure will cost more, but so you will forget about the problem of turning off the device in the cold for the next 2-3 years. Given that the cost of installing a new battery is slightly higher than the price of an external battery, and if the iPhone is otherwise satisfactory, why not use the service center to postpone the purchase of the next smartphone for another couple of years.

Home / Apple / iPhone / iPhone shuts down in the cold: what is the cause and how to fix it

What to do if your iPhone shuts down in the cold?

The first thing you must do is try to turn your iPhone on. If it does not respond to pressing the Power key, you need to go indoors and wait 20-30 minutes until the device has “warmed up” to room temperature. After that try to turn it on.

If even after an hour or two of being indoors your iPhone does not want to turn on, you need to put it on charge. Note that in this case the charging time of the smartphone can increase significantly. up to several hours.

If nothing helps, contact the service center.

What to do so that the iPhone does not turn off in freezing temperatures?

The manufacturer itself does not recommend customers to use smartphones if the air temperature has dropped below 0. But in our reality it is quite difficult, so we have to look for other ways to fix the situation:

  • Buy a case. Ideally, any model that covers all sides of your iPhone (an excellent option would be a slip case).
  • Use a rechargeable case. This is a radical way to save your gadget from the problem of low temperatures, but the cost of such accessories is quite high.
  • Use a portable power bank or portable battery pack. You can carry it in your bag, or even in your. and then simply unplug it before you use it.
  • Keep your gadget close to your body. It will be an excellent protection for your smartphone from the cold.
  • Use a headset. Most often iPhones are turned off in the cold time of year just during the call, so even the simplest headset will help to avoid this problem.
  • Fully charge your device before you leave the room. The more charge you have, the longer your iPhone will last.
  • Use a different smartphone for navigation, because in a frozen overnight car your iPhone will shut down in minutes.
  • You can “warm up” your device with an app or game. Before you go outside, turn on a sufficiently demanding game that the battery can keep warm.

Why the iPhone shuts down?

The main cause of iPhone instability in the cold is the lithium-ion battery. If the operating temperature is below a few degrees of heat, it quickly loses its maximum capacity. The smartphone starts to reboot, does not respond to user touches, or freezes. Eventually, the iPhone runs out of power and shuts down.

According to Apple recommendations, the optimum temperature for the iPhone is from 0 to 35 degrees. If you use the device outdoors in the fall and winter, these conditions are unrealistic. But it is possible to save the device from sudden shutdowns.

Li-ion batteries are not resistant to low temperatures

BatteryUniversity site.com claims that at low temperatures, the internal resistance increases and the capacity of the lithium-ion battery decreases. The article gives an estimate, according to which at the temperature of.18 Celsius battery capacity will be half of the original.

Global News Canada conducted an experiment in 2014 in which an iPhone left out in the cold for 30 minutes lost 14% of its charge, while its counterpart at home drained only 1%.

The official operating temperature range for Apple mobile devices is 0 to 35 °C. It’s easy to go outside this range in the summer, leaving your phone in the sun, and of course, in the winter, just by taking it out of your in the freezing cold.

The iPhone is calibrated for warm temperatures, so it may vary greatly in cold weather from its actual charge level due to a reduced capacity of the battery. That’s why your phone may turn off even when the indicator shows 30% charge.

What to do if your phone shuts down in the cold

Try not to take your phone out and do not use it for a long time. Let the smartphone, while you inevitably turn into a snowman and get covered in a layer of ice, stay in a case or in a warm distant after all. Or better yet, in two protectors at once. If you do not have a special case or you do not like unnecessary bulk, wrap the phone at least in some kind of handkerchief / glove / loincloth. And stash it in your bag or backpack. The main thing is to protect the battery from cooling, then there should be no problems (at least with the disconnection).

In times of wild cold, you can try a cell phone. You don’t have to use it. it can just be a guarantee of being able to make an urgent call. Button phones are quite good at low temperatures, particularly thanks to the usual keypad.

Having begun to warm the iPhone you need to wait for the battery to start working in normal mode. System errors may occur during the emergency shutdown, so perform a forced reboot by holding down the Home Power buttons (and on the iPhone 7 | 7 Plus, also Volume Down), and when you see the Apple logo, you can let go.

And if the iPhone does not turn on after it has cooled down a lot, then it is the way to the service center.
