iPhone does not turn on after a freeze what to do

Iphone shuts down in the cold: why and what to do?

Formally winter lasts only 3 months, but in fact even in the middle belt of Russia it can drag on for a month or two. With the onset of winter problems arise, and they often appear, as it may seem, out of nowhere. For example, your favorite iPhone simply shuts down in the cold. Why it happens, what to do and what other trouble to expect? About all this. In our article.

Li-ion polymer batteries (Li-Pol) are used in iPhone smartphones. In fact, these are advanced lithium-ion batteries, which are endowed with a higher energy density per unit volume and mass. However, these batteries have disadvantages: at temperatures below 5 ° C, they can lose some of its properties, resulting in an increase in internal resistance, reduced capacity, the battery is not able to give the declared current, resulting in a smartphone can just take and turn off. Interestingly, the manufacturer itself does not prohibit using the iPhone in the cold, besides it would be, to put it mildly, strange.

It should be noted that modern models like iPhone 6, 6s, 7, 7 Plus, etc.Д. It shuts down much less often in the cold. Most of all affected models that have been in use for a long time: batteries have a limited number of operating cycles, and after crossing a certain threshold, they begin to rapidly lose their properties.

If your iPhone is turned off in the cold, it is very likely that nothing bad happened, and that it turned off because of the sub-zero temperature.

Possible causes

Before giving an exact answer, why the device does not turn on, it is necessary to consider the main causes of malfunction:

• Mechanical damages. If the phone was hit, was under a lot of pressure or fell, most likely the hardware of the phone was damaged. It is impossible to detect such a thing “by eye”, the only exceptions are obvious deformations on the body or shattered glass.
• Loose cable on the board connector.
• Damage to the motherboard, cracks and other defects.
• Getting wet. Regarding the “ten”, such a thing is almost impossible, the manufacturer has protected the case in accordance with IP67. Despite the official statements, there is a small chance of defect, which can cause a sharp shutdown.
• Problems with the operating system. The smartphone starts working erratically after an unsuccessful iOS update.
• Not enough charging the battery. One of those problems that are the last to think about. The drop in charge to zero, can provoke the cold or connection to the charger through a faulty power cable.
• Overheating or overcooling.

Exactly how the phone will behave because of the breakage is impossible to predict. Consider the most common complaints.

The main causes

Now let’s look at the more significant causes that relate to the hardware of the device. It is worth saying straight away that such damages are almost impossible to fix at home. Only replacement of the whole module will help, and in the conditions of the service center.

Repair complex electronic equipment by yourself only if you have repair skills and special equipment.

The lightning connector is broken or clogged

The main power connector can fail for several reasons:

• Dirt, threads, dust and grime in the socket. This situation can often be observed if the user carries the smartphone in clothing s or in the purse. There is lint or small debris in the connector.
• Fracture of the contact group. Such a breakdown is difficult to recognize at a glance. The plug is likely to be a little loose in the socket when inserted for charging.

Do visual inspection. Check the condition of the jack. Try blowing out or cleaning it with a toothpick. Be careful. Use special silicone plugs to prevent clogging.

Battery is dead

One of the most frequent reasons for the sudden shutdown of a smartphone, both during a conversation and in the cold. There are several signs of “dying” of the battery:

• Most obvious and dangerous. Bloating of the case, delamination of the display. You must replace battery immediately. Further operation of the gadget is dangerous!
• Phone sharply turns off with 10%-30% of charge remaining. Most likely. Battery is dying out.
• Iphone goes out unresponsive to touch and button presses in sub-zero temperatures below.1°С. Happens even when the battery is at least 100 percent charged.

Replacing the battery will cost the user about ₽3000-₽8000 depending on the model. These rates are given by official service centers. Private workshops can take a little less, but you can run into non-original.

Another thing related to the battery is the “sleeping battery” effect. Most often occurs if you leave the gadget for a long time without recharging. For example, for more than 2-3 months. In this case, in the lithium-ion battery begins destructive processes at the chemical level. The battery drops to 1-2 volts, which is critical for functioning. The charge controller reads these readings. The chip blocks charging, saving the battery from damage (bloating, explosion, and other things) and protecting the electronics from voltage surges.

To bring such a battery back to life you will need to disassemble the case of the device. Remove the battery, and push (recharge) the cell with the help of a universal charger “frog”.

This method allows you to revive the battery for a short period of time. However, this is a temporary measure that does not restore the battery to its normal state. Still need to replace the battery.

The power button is broken

Buttons on the iPhone look good. The keys are made of aluminium and are virtually indestructible and unbreakable. What can not be said about the spring mechanism, which provides the actual pressing and closing the circuit. This element can crumble from a shock or too much pressure. Sometimes the iPhone lives its life, then suddenly turns off, then on. Another symptom. After a call the screen is black and the system does not respond to taps.

If the button has stopped responding tactilely, there is no specific click, pressing it is slow, or you have a feeling that the button is stuck. Most likely the spring mechanism is broken. It is not recommended to change the module at home. It is better to take your device to a service center.

The virtual “power” key can be a temporary replacement for the mechanical power key. Go to “Settings”, then to “Main”. You should find “Universal access”. Activate the item “Assistive Touch”. After that place the virtual button in any convenient place on the display.

Charge controller burned out

The charge controller is a special chip that is responsible for the correct charging of the battery. The chip can fail for a variety of reasons:

• Connection of non-original or broken accessories. Do not use Chinese “noname” chargers and cables, as well as broken or bent wires.
• Mechanical impact. Severe shock, body compression.
• Power surge. Such breakage often occurs when charging from a car cigarette lighter using a low-quality charger.
• Moisture. The board is short-circuited by moisture (for example, after falling in the snow, bathtub or toilet) on the contact group.

Replacement of this module will cost the user ₽1500-₽8000 depending on the smartphone model.

Malfunction of the motherboard

The main iron part of the device is the motherboard. The processor, memory and other important chipsets are soldered onto it. If this component burns out, then the device just “shuts down” (stops switching on) or starts flashing randomly on the white or red screen. There are all kinds of causes of motherboard failures:

• Mechanical impact. Heavy knocks, dropping on the floor, twisting. All that leads to cracks in the board’s textolite. The motherboard fails.
• Moisture entering the case. Some contacts on the board are short-circuited.
• Improper repair. The interior of the iPhone is notorious for having a large number of mounting bolts of varying lengths. Some craftsmen do not remember the location of screws. They screw long screws straight into the board, breaking it.
• Burning out of individual components. Like the memory chip or the processor.

Repairing the board is expensive. For example, a new motherboard for an outdated iPhone 6 costs ₽3000-₽5000, while the newer 11 and 12 models cost 30,000-50000.

Dropping or drowning

A normal drop or falling into water can cause a complete shutdown of the gadget. In some cases, the electronics read the information from the built-in sensors (moisture) and activate the emergency mode. But more often the damages occur on the internal components of the board or the chipset.

The surest way to deal with liquids on your smartphone is to immediately copy all the information to an external storage device.

Of course, you can dry it with “folk” methods. But this method works with an error of 50/50. Precious time will run out, information will stay in the bowels of the iPhone.

Why other brand smartphones perform better in cold than iPhone?

Many devices from other companies work even in thirty-degree cold without any problems, while iPhones often shut down. There are two main reasons:

• Case material. Some of the latest iPhones are made of aluminum, which has a high thermal conductivity, so the gadget freezes quickly. The same applies to the glass that older models are made of.
• The small thickness of the case. If the smartphone is thin, its battery will start to work unstable faster, and Apple gadgets are hard to call thick.

Competitors of the famous American company often make the bodies of their smartphones from plastic, which conducts heat much worse than aluminum and glass.

Causes

The most common causes of iPhone 6 does not turn on after a discharge include a failure in the power circuitry, microcontroller failure or software errors. Troubles related to internal parts and “iron” should be entrusted to professionals. Failure in the program can be corrected by yourself.

Iphone 6 is out of charge and won’t turn on

If the smartphone does not respond to power on when connected to charge, there was a deep discharge or a malfunction at the operating system level. If the iPhone 6 deep discharges, you need to follow the steps below:

When the Apple logo lights up on the display, you need to release the keys;

Enable and disable silent mode if your smartphone does not boot up;

If the iPhone 6 does not turn on after a frost, what should the user do?

Go into a warm room and leave the phone there for about 30 minutes;

After that you can connect iPhone 6 to the mains.

Apple electronics don’t work well at subzero temperatures. Long stay in the cold can cause a complete discharge of the device.

Iphone 6 won’t charge or turn on

No charging due to several factors: broken battery, broken power/charging controller, or non-original cord or power adapter. First of all, you need to check the cable. There should be no kinks or tampering. You should also make sure that you use the original wire. If you have an optional charger, you need to connect your iPhone 6 to it. If the phone starts charging, the old cable is broken.

If replacing the wire did not help, the failure is caused by the battery or the controller. These parts can only be changed at a service station.

Why the iPhone heated up and does not turn on?

The reason for this can be a number of factors, we will consider common ones:

• A problem occurred that caused the phone to overheat. In such case it is necessary to let phone to cool down. To be sure that it is a system failure, press the lock and “Home” button simultaneously, holding for 15 seconds, the phone should then turn on.
• In a case if the phone has been moistened, or has simply switched off from overheating. The first thing you should do is let it cool down. In this case, do not connect the gadget to the charger or computer, put it in a cool place. After it cools down completely it should turn on.
• The charger is defective. Broken charger or use of low-quality cables also leads to overheating of the phone. So if your iPhone is hot and won’t turn on after charging, you should cool it down and get yourself a new charger.
• There has been damage to the battery, which leads to increased power consumption and heating.
• Another option may be the requirement to install new firmware on the gadget. Unfortunately, it could also heat up and now it refuses to turn on.
• You got your hands on a fake. If you were not able to immediately distinguish between the original phone and a copy, and you used a Chinese iPhone, it is likely that it has overheated and will not turn on, and most likely will not even work anymore without repair.

But now comes the question of what to do if the iPhone is hot and will not turn on?

Recommendations for using your iPhone in the cold

Experts have a few recommendations that will help to keep your iPhone working at low temperatures.

When using your iPhone in the winter, you need to follow some recommendations

First of all, you need to take into account the limitations that in severe frosts for the iPhone. When your iPhone is running at a lower temperature.20 degrees, it can automatically switch to emergency power saving mode. In this case, as a rule, the smartphone screen goes out, and the device stops charging.

In addition to this there are other recommendations:

• Carry your phone in your inside s. In winter the temperature in the outside s of the jacket is almost the same as outside, so it is unlikely to save the battery charge of the iPhone in them. While outdoors, it is recommended that you keep your phone in its inside s, which are better able to withstand the temperature of the human body.
• Headphones. To avoid taking your phone out of your inside every time you want to answer a call, you can purchase a special headset. The best option would be inexpensive headphones that do not have a battery, which can lose its performance in freezing temperatures.
• A case with a built-in battery. If you put a case with built-in battery on the iPhone, it ceases to be thin and elegant. But such a case will provide reliable protection for the device. It will also supply power to the battery and warm it up, which will allow the smartphone to “survive” in subzero temperatures.
• Demanding games. If you take your iPhone in winter and turn on a demanding game, then the processor will immediately begin to heat up. It is better not to do this, because the subsequent rapid cooling of the processor can severely damage the device.
• No need to leave your phone in the car. To avoid overcooling the iPhone, it is not recommended to leave it in the car even for a short period of time. The exceptions are when the car is running and the temperature is relatively high.
• Do not try to revive the phone. Some people even after their iPhone has been turned off by the cold, try to return it to normal functionality. It is important to remember that such actions cause great damage to the battery of the device.
• No need to try to warm up your iPhone with foreign objects. Some people are in such a hurry to get their phone back on, they resort to a rather interesting solution. Warming it up with a hair dryer. Do not do this in any case, as the hot air pressure from the hair dryer can simply melt the plastic parts of the phone.

Important! The connection and network may be temporarily lost. Do not worry about it. To turn the gadget back on, you need to put it in a warm place and leave it there for about an hour.

If you follow all the above recommendations, even in extremely cold weather, you’ll be able to keep your iPhone battery charged.
