iPhone 7 shuts down when cold. Why does the iPhone turn off in the cold and what to do in such cases? How to protect your iPhone from the cold

All tips

Hi all. Today, a problem that was once again raised by a reader of our site Oleg (this is not the same Oleg who advertised The Binding of Isaac). In the letter, he described the situation that every second iPhone user faces...

Good afternoon, Dmitry! I am a reader of your iPadstory website. I ran into one problem.
iPhones' battery capacity drops catastrophically quickly in the cold. Right up to turning off the gadget. In just half an hour of using the device in slightly cold weather (-5), my charge level dropped from 80% to 0%. (iPhone 6 plus without jailbreak). From communicating with many of my apple grower friends, it became clear that the same thing is happening to them. Do you, by chance, have any thoughts on how to solve this problem?

Yes, I also have this problem... I first began to notice this in September 2016, when even at above-zero temperatures on cold nights the iPhone suddenly dropped its charging percentage. That is, it could be 35 percent; as soon as you used the phone for one minute in the cold, the percentage dropped before your eyes to 10-20, or even the phone turned off completely. The strangest thing is that if I gave the phone a small charge from the Power Bank, it would turn on again and the charge would immediately show about 20 percent on the screen...

Just yesterday, my phone turned off in the cold at some minus 5 degrees at 38(!) percent! Apple, what did I pay 43 thousand for at one time?! So that the phone turns off at the slightest cold? Is it intended only for California? Have you tested it somewhere in the northern regions?

IN iPhone description 7 on the Apple website you can find the following lines:

Operating environment requirements

Operating temperature: 0 to 35 °C

Storage temperature:-20 to 45 °C

That is, the phone was not initially designed for use at sub-zero temperatures. Why? In fact, the problem has nothing to do with iOS updates, nor with the version of the phone itself. Every year, with the onset of cold weather, people ask these questions on specialized forums around the world. Questions have become more frequent since 2013... Why? Let me explain.

The culprit of the problem can be considered a modern battery

Chemical reactions occur inside all batteries and they slow down in the cold... Why does the iPhone 4S and older ones global problems did not have? Starting with the iPhone 5, batteries have become noticeably thinner. That is, the contact area with the body is larger. The larger the area, the faster the cooling occurs.

An additional side factor is that the iPhone body now consists of thin aluminum, which conducts both cold and heat well... On the one hand, fast heat transfer is a plus, because the phone does not heat up even in the heaviest games. On the other hand, it cools faster in the cold. That is why, if the phone body is made of plastic, it will survive better in the cold.

I don’t see any other equally logical explanations...

In sub-zero temperatures, follow these rules:

Move the phone closer to your body: for example, from your jeans pocket to the inner pocket of your jacket/coat/fur coat.
In principle, do not leave your phone in the cold. If you are going to spend a lot of time in the cold, it makes sense to turn off your phone temporarily.
Reduce conversations in the cold to a minimum. Another option is to use the headset more often in winter. If they call you, if possible, go into the room and calmly call back.
Do not charge or turn on a frozen smartphone. Let it warm up to room temperature (20-40 minutes). But do not specifically place the phone on heat sources (batteries, heaters, etc.)!
It might make sense to buy a warm cover. I searched for solutions on Ali and found a lot of options, but most of them look somehow feminine... For girls, the choice is huge. I don't know how effective such covers are.

They write on the Internet that the best solution is the Salt case (official website), the price of which is up to 50 bucks (+delivery). Its trick is that the material there is the kind that NASA uses in the rocket industry. It protects against temperature changes. This case was once raised on Kickstarter, but is now available for sale.

If we take the general case, we should remember that plastic cases poorly protected from the cold. In winter, it is better to use products made of felt or leather (for example, this case for iPhone 7 and 7 plus).

Write everything you think about this problem. Do you have any other solutions? :)

Winter has come, and with it severe frosts, and technical support and forums have traditionally been filled with user complaints about fast discharge batteries and full turning off iPhone and iPad in sub-zero temperatures. Observers have figured out what is happening with the charge of gadgets, and what to do about it.

Indeed, in severe frost you cannot talk on the phone for a long time: the device begins to behave strangely, and then shows a low battery indicator and turns off. This is especially common for users who have chosen Apple products. The American manufacturer explicitly states on its website that it does not guarantee stable work their smartphones and tablets in temperatures below zero Celsius.

If you spend a long enough time outdoors at a temperature of about -5°C, the iPhone and iPad may experience malfunctions; at -10°C Apple devices show indicator complete discharge battery and turn off.

However, in fact, the battery does not lose charge in the cold - it remains at the same level as before. However, with prolonged exposure to sub-zero temperatures, the battery gel, which plays the role of an electrolyte in modern lithium-ion or lithium polymer batteries, changes its density, becomes more viscous, the speed of movement of charged lithium ions slows down, which leads to a decrease in capacity and other indicators of the battery.

The smartphone may not have enough power to launch applications correctly and perform current tasks, and the battery controller perceives a drop in its characteristics as a signal of battery depletion.

Low temperatures also affect the screen and sensor. The response speed of liquid crystal cells slows down, and you can see a loop when animating interface elements. Only AMOLED displays are less susceptible to low temperatures.

Different manufacturers have different attitudes towards operating their products at sub-zero temperatures. If Apple strictly sets the operating range of its smartphones and tablets from 0°C to +35°C and refuses warranty service, if the smartphone was used outside this range, then other manufacturers do not set such strict restrictions, and their smartphones can operate at temperatures below -10°C. However, along with the race for the thickness, weight and power of smartphones, device cases are becoming thinner, the filling is becoming more and more complex, and the influence of frost on their operation is becoming more noticeable.

However, with proper using iPhone even in frosty weather nothing will happen to him. We must remember that it will turn off only with prolonged exposure to sub-zero temperatures, so you can quickly look at the message or check the map, but if you still need to talk for a while, it is better to go indoors or use a headset, putting the smartphone in the inner pocket of warm clothes.

In order to preserve the precious heat of the device, you can resort to sufficient simple method, “wrapping” it in a case that will not only protect it from falls, but also help extend the operating time in the cold. Even simple Silicone Case not much, but it reduces thermal conductivity, due to which the device cools more slowly. Greater effect can be achieved by carrying your smartphone in a thick felt case.

Also hold out phone longer launched in background a resource-intensive application, such as a demanding 3D game. This will increase the temperature of the processor and, as a result, the overall temperature in the case.

If your smartphone is still frozen, you should not rush and take active steps to resuscitate it (charge, dry, put it on the battery, etc.). The best solution will let it sit for an hour or two at room temperature. After this, the battery will return to its standard characteristics, and the condensation that forms due to temperature changes and can close the contacts will dry.

It is especially not recommended to charge a frozen battery and warm it. The fact is that due to temperature changes, the battery case can be deformed and depressurized, and an active element such as lithium, reacting with oxygen, can cause a fire or even explosion of the battery.

A case that became famous in 2011 was when a Norwegian woman decided to connect her iPhone in a cold car to car device charging at 12 degrees below zero. The body of the smartphone was deformed, the screen burst, and, according to the owner, her eyes were saved from shrapnel only by the fact that she was wearing glasses. Apple refused to compensate for the damage because the iPhone was operated in sub-zero temperatures.

Formally, winter lasts only 3 months, but in fact, even in central Russia it can linger for a month or two. With the onset of winter, problems arise, and often they appear, seemingly out of nowhere. For example, in the cold favorite iPhone it simply turns off. Why does this happen, what should I do and what other troubles should I expect? All this is discussed in our article.

Why does my iPhone turn off in the cold?

IN iPhone smartphones lithium-ion batteries are used polymer batteries(Li-Pol). Essentially, these are advanced lithium ion batteries, which are endowed with a higher energy density per unit volume and mass. However, such batteries also have disadvantages: at temperatures below +5°C they can lose some of their properties, resulting in increased internal resistance, the capacity decreases, the batteries are not able to deliver the declared current, as a result of which the smartphone can simply turn off and turn off. Interestingly, the manufacturer itself does not prohibit using the iPhone in the cold, and besides, it would be strange, to put it mildly.

Note that modern models like iPhone 6, 6s, 7, 7 Plus, etc. They turn off in cold weather much less often. Models that have been in use for a long time are most susceptible to this: the batteries have limited quantity working cycles and after crossing a certain threshold they begin to rapidly lose their properties.

If your iPhone turns off in the cold, most likely nothing terrible happened and it turned off precisely because of the sub-zero temperature.

What to do if your iPhone turns off in the cold?

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

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

If all else fails, contact a service center.

What other problems arise with the iPhone in the cold?

Shutting down in the cold is not the only problem that can await iPhone user. What else?

Firstly, the battery drains faster. This, again, is directly related to Li-Pol technology. However, we note that the problem of faster discharge of the gadget in the cold is relevant for almost all devices with batteries.

Secondly, in the cold the touchscreen may stop responding to presses. iPhone screen. Imagine trying to click on an application icon, but nothing happens. There is no need to sound the alarm, try to enter the room and after a while the sensor should work.

How to protect your iPhone from the cold?

There is no perfect solution, but we will give you some tips that can help keep your smartphone fully functional.

Try to keep your gadget in the cold as little as possible. For example, you talked to a friend and immediately put your iPhone in your pocket. Or even use a headset for communication.

Keep your phone in a pocket that is closest to your body - it is warmest there. Or use the inside pocket of a jacket or down jacket.

You can purchase a cover. The case saves your smartphone not only from scratches or falls, but also from the cold. Of course, the cover will not be able to completely protect against frost in any case.

Hi all! In the cold season, owners of gadgets from many companies (and Apple is no exception) may experience unpleasant surprises. The fact is that when left in the cold, the iPhone can very quickly lose charge and turn off almost immediately. Moreover, looking ahead, I would like to note that in most cases this will be the case. Is it normal this situation? Why is this happening? Should I run to change the battery or “something worse has broken down there”? Now we'll find out everything, let's go!

But first - personal experience. I didn’t have any problems with the iPhone 4 and 4S, but subsequent models, starting with the 5th, behave inadequately in the cold. Perhaps this is due to the case materials (aluminium), perhaps with the decreasing thickness of the devices - but the fact is there and it cannot be denied, latest models iPhones are very sensitive to low temperatures. You go outside in winter with 60% charge, you want to listen to music on VKontakte or take a photo of something, and almost immediately the phone simply turns off - the battery is discharged.

Perhaps this is why there is a whole section on the Apple website dedicated to this kind of ailment.

Let's turn to it and find out what is installed in the iPhone lithium ion battery, which has both advantages and disadvantages. One of them is the operating temperature range, which ranges from 0 to 35 degrees Celsius. It is this temperature that Apple calls “room temperature” and optimal when using iPhone, iPad and iWatch.

Although, of course, these values cannot be taken as the last resort. Errors exist - even if it’s just above zero outside, the iPhone can still discharge quickly. This is normal and there is nothing to worry about!

By the way, the company itself does not prohibit the use of the device at low temperatures, but notes a possible decrease in battery life. However, it states that when the temperature returns to normal, the battery returns to its normal state. So there’s no need to worry that using your iPhone in the cold will somehow harm it. Much scarier, but not everything is so simple there either.

It is almost impossible to avoid a rapid discharge in the cold, but there are several things that can help in this situation, a little, but still:

Use a cover.
Carry a portable charger with you. The fact is that it takes a lot of energy to turn on, and in the cold there is none. Therefore, a portable charger can help turn on your phone.
Carry your iPhone in the inner pocket of your jacket, so to speak, closer to your body and warmer.

As a result, we note that rapid charge consumption and subsequent turning off iPhone in the cold - this is quite normal. And there is no need to worry about this.

However, if you know that you will be using your smartphone in low temperatures, it is better to prepare for this in advance. Although except portable charger You can’t think of anything else - it’s not like sewing a fur coat for him, after all? :)

Winter is a wonderful time of year, but not for our iPhones. As soon as the thermometer drops below zero, they begin to turn off outside. A sad fact that I encounter every year. Why this happens and what to do about it, I’ll tell you now.

What happens to the iPhone in the cold

cnet.com

Frosty air and iPhone don't mix well. The latter begins to quickly discharge, slow down or suddenly turn off. According to Apple, the optimal temperature for normal iPhone work- from 0 to +35 °C. It can be stored in the switched off state at temperatures from –20 to +45 °C.

In fact, the iPhone begins to behave strangely at temperatures close to zero. The screen does not respond well to touches, the smartphone loses the network, reboots on its own or turns off completely. Why is that?

Lithium-ion batteries are to blame. In cold weather, battery ions lose their properties, as a result, internal resistance increases and capacity is lost. It is lost, of course, temporarily, but because of this, the iPhone can turn off, even with more than half the charge.

How to deal with it

1. Charge your iPhone to 100% before going outside

Simple but effective advice. The more charged iPhone battery before leaving, the longer it will work. It is better to fully charge it before going out into the cold.

2. Carry your smartphone in a case

I don't like covers. There is no desire to hide such a stylish thing as the iPhone X in a case. However, in winter, it will not only protect your smartphone from meeting the asphalt, but will also prevent it from freezing quickly.

3. Use headphones

theverge.com

Use headphones and a headset for communication in winter so as not to have to take your smartphone out of your warm pocket again. Ordinary wired ones, which do not have batteries, are best suited: this means they will not become dull in the cold.

Although my AirPods have already survived one winter and there were no problems. However, these are rather questions for winter.

4. Run heavy games

To heat up the processor and prevent the battery from cooling down, run some heavy application or game before going outside.

5. Don't use your iPhone as a navigator in winter

The iPhone does not work very well in a cold car after the night, so it is not advisable to use it as a navigator in winter, otherwise it will turn off on the way to work. Also, during this time of year, don't leave your iPhone in the car, even for a short time.

6. Keep iPhone close to your body

Wear iPhone is better in the inner pocket, closer to you. If your smartphone is in the side pocket of your jacket or jeans, there is a greater chance that it will freeze and turn off.

What to do if your iPhone freezes and turns off

imore.com

First of all, take your smartphone to a warm place. Warm up your iPhone gradually so that there is no sudden temperature change. You cannot place your phone on the battery or keep it near the stove in the car - otherwise condensation may form.

It’s also not worth rushing straight to charge, it will only harm your smartphone. Try turning it on after 30–40 minutes. Turned on? Cool. If not, and there is a charging icon on the screen, it means the battery is completely discharged.

In winter, it is better to always have an external battery with you to recharge your smartphone at any time. It should be compact, lightweight, practical. Optimal volume batteries - 10,000 mAh. Less - there is no point, more - usually heavy, and not all airports will let you through. You'll have to explain what this thing is and why you need it.

Which external battery to choose

techniblogic.com

First of all, I advise Xiaomi batteries. Reliable, stylish, comfortable. If Apple did external batteries, they would look something like this.

I use Mi Power Bank Pro 10,000 mAh. Aluminum, thin, Space Gray, almost like a MacBook. There is a fashionable USB-C, through which it is charged. There is support fast charging, both for the battery itself and for the devices connected to it.

The only thing is: an aluminum case is not the most suitable option for winter; it is better to choose plastic. And one USB is not enough, I would like a pair. Otherwise, it's a great product, I recommend it.

The second cool battery is ASUS ZenPower ABTU005. Small, plump - and again, nothing extra. Battery capacity - 10,050 mAh. There is a USB port for output and microUSB for charging the battery itself. Produces 2.4 A, charges itself in exactly 5 hours.

harper.ru

The third battery I recommend is the Harper PB-10005. Black box for 10,000 mAh with microUSB and a pair of USB. This is an extremely useful thing because you can charge, for example, your iPhone and headphones at the same time. Produces 2.4 A, operating voltage is 5 V. The battery itself takes 5–6 hours to charge.

I hope these tips will help you survive the cold with your favorite smartphone.
