What if Apple's mobile phone crashes at low temperature?

1. The reason why Apple's mobile phone crashed at outdoor low temperature.

1. Cause analysis:

Generally, the ambient temperature for normal operation of mobile phones is zero to 40 degrees Celsius. If the ambient temperature is too high or too low, the electronic components of the product may be damaged, and the screen may fail and crash inexplicably.

At present, most mobile phones use lithium-ion batteries. When the temperature is too low, the capacity of ordinary lithium batteries will be attenuated, but it is basically unaffected at 0 degrees Celsius. When it reaches-10℃, the capacity may be only about half, so at low temperature, the battery will be charged but cannot be released.

Nowadays, touch-screen mobile phones are becoming more and more popular, and the cold weather can easily affect the normal work of the screen. Generally, the working temperature of the capacitive screen of a mobile phone is zero to 35 degrees Celsius. If you use the mobile phone below this temperature, it is easy to cause touch screen failure and other phenomena. When the screen fails, it is normal to put the phone in your pocket and wait for it to run for a while or warm up.

Buying a protective cover for your mobile phone is also an effective way to keep warm. If you answer the phone outdoors, you can talk with headphones.

2. What should I do if my Apple phone can't be turned off because of the low temperature?

Users who encounter the problem of iPhone X crash in cold weather can only use their mobile phones in places with relatively high temperature.

According to foreign media reports, many iPhone X users began to give feedback. In places with low temperatures, their mobile phones began to crash for no reason, which was very annoying. This issue has also attracted the attention of Apple.

It is mentioned in the report that Apple is investigating this large-scale low-temperature crash of iPhone X, and the supplier of flexible printed circuit board of mobile phone is Interflex of South Korea, which will be the main reason for this incident. At present, they have stopped production to cooperate with Apple's investigation.

It is reported that Interflex supplies printed circuit boards for iPhone X, and various components such as chips and displays are connected here. However, the organic light-emitting diode screen of iPhone X sometimes has the problem of insensitive or inaccurate response, which is basically caused by circuit board problems.

Extended data:

The optimum temperature of chemical reaction during lithium battery charging is above 65438 00℃.

Professor Zhang from the School of Physics and Electronic Engineering, Jiaojiang Campus of Taizhou University told the reporter that mobile phone charging is the process of converting electric energy into chemical energy. When the ambient temperature is too low, the movement of electrons slows down, which is the main reason for the difficulty in charging.

"When the temperature drops below 10℃, the charging speed of the iPad will be affected. In addition, the charging speed of batteries with different capacities is also different. The more saturated the battery, the slower the charging speed. " Mr. Yan further explained.

It is understood that the current electronic products on the market, including mobile phones and tablet computers, all use lithium-ion polymer batteries. Most lithium-ion batteries are equipped with low-temperature protection. The larger the battery capacity, the higher the protection level. The iPad is close to the computer, and the lithium-ion battery is set at about 5℃. The low temperature protection of mobile phone lithium-ion battery is set at about 0℃, which is caused by the different chemical reaction substances in the two batteries.

The optimum temperature for the chemical reaction of lithium battery during charging is above 10℃, so it is best to charge it in a warm room to avoid unnecessary damage to the battery.

4. What should I do if my 4.iphone is turned off at low temperature? IPhone will automatically turn off at low temperature.

What should I do after freezing?

If your iPhone is unlucky, don't panic. It's not that the phone hardware is broken, nor that your phone is dead. Only the iPhone started the "self-protection" mechanism and entered a frozen state. The way to save it is very simple, that is, bring your iPhone from a cold environment to a warmer environment, and then try to turn it on when the body warms up slowly. If the phone still can't be turned on after a period of time, you can try to press the "Home+Power" key for 5 seconds to restart the phone.

It should also be noted here that you should never put the iPhone in a sub-zero temperature environment for a long time directly close to a very hot radiator or electric blanket for the sake of "quick recovery", because it is easy to cause condensation on the circuit board of the mobile phone. If this phenomenon is serious, a short circuit may occur after the phone is turned on.

Especially the mobile phone products with metal shell like iPhone 6/6s, we must avoid this environment with large temperature difference. When you bring your mobile phone indoors or outdoors in high temperature in winter, don't turn it on immediately, but leave it for a while before turning it on.

Suggestions on using mobile phones in low temperature environment

Of course, the above situation is not just the iPhone. As long as your mobile phone is equipped with a lithium-ion battery, using it for a long time in the above cold environment is likely to "pretend to be dead", especially for mobile phone users in the north.

In a low temperature environment, it is recommended that you use your mobile phone as little as possible. If it is unavoidable, you need to shorten the use time every time. After using the mobile phone, it is best to put it in a close-fitting or warm place. Once the battery temperature returns to the normal operating range, its performance will also return to normal. Similarly, if the battery temperature exceeds the critical value (generally around 35℃), the mobile phone will also have an alarm of battery overheating, and will also take the method of automatic shutdown to slowly cool down the mobile phone battery.

5. What should I do if my 5.iPhone shuts down automatically at low temperature?

1, the main reason for automatic shutdown is that the weather is too cold. 2.2. The working temperature of the lithium battery of iPhone is 0℃ to 35℃. If it is lower than 0 degrees or higher than 35 degrees Celsius, the battery performance will be reduced, and even it will automatically shut down if it is lower than 0 degrees.

3. On the Apple official website, there is a description: Please use the iOS device in an environment with a temperature of 0 C to 35 C (32 C to 95°C). Low or high temperature environment may cause the equipment to change its behavior to adjust the temperature.

Using an iOS device in a cold environment below the operating temperature range may temporarily shorten the battery life and cause the device to shut down. When the equipment returns to a higher temperature environment, the battery life will return to normal.

4. After automatic shutdown, as long as Home+Power is pressed together for 5 seconds, it can be turned on normally.

6. What is the reason for the high-temperature and low-temperature crash of the mobile phone?

Cause analysis:

Generally, the ambient temperature for normal operation of mobile phones is zero to 40 degrees Celsius. If the ambient temperature is too high or too low, the electronic components of the product may be damaged, and the screen may fail and crash inexplicably.

At present, most mobile phones use lithium-ion batteries. When the temperature is too low, the capacity of ordinary lithium batteries will be attenuated, but it is basically unaffected at 0 degrees Celsius. When it reaches-10℃, the capacity may be only about half, so at low temperature, the battery will be charged but cannot be released.

Nowadays, touch-screen mobile phones are becoming more and more popular, and the cold weather can easily affect the normal work of the screen. Generally, the working temperature of the capacitive screen of a mobile phone is zero to 35 degrees Celsius. If you use the mobile phone below this temperature, it is easy to cause touch screen failure and other phenomena. When the screen fails, it is normal to put the phone in your pocket and wait for it to run for a while or warm up.

Buying a protective cover for your mobile phone is also an effective way to keep warm. If you are outside, you can talk with headphones.

7. Apple's mobile phone crashed. What should I do?

For some people who are new to Apple mobile phone users, they will certainly encounter some very difficult problems, such as

For smart phones, the phenomenon of crashing is very common. There are many reasons for the crash, which may be the installation of unstable or conflicting software, or the unknown bug of the system itself. Let's talk about the handling method when the iphone4 crashes.

Method 1: ends the current program.

When the system is unresponsive or the touch screen is unresponsive, quickly click the Home button twice, and a list of current and recently running programs will appear.

Press and hold the icon of any program with your finger until a small red stop sign appears in the upper left corner of the icon and starts to shake slightly.

Then click on the small red sign in the upper left corner to end the background program and release the running memory of the mobile phone. According to your own situation, choose how many to end. What is demonstrated here is that all the programs are over.

Method 2: Use 9 1 mobile assistant to recover.

After the mobile phone is connected to the computer, open the 9 1 mobile assistant, see the top of the main interface window of the program, and click and select the "Complete function" item.

Select "one-button cleaning" among many function options.

Then you can see the options of cleaning up the mobile phone, including cleaning up the mobile phone garbage and optimizing the operation efficiency of the mobile phone. It is recommended to tick all the boxes, and then click "Start scanning". Then the mobile assistant will scan out the garbage in the mobile phone and remove it, so as to optimize the operation efficiency of the mobile phone and reduce the probability of the phone crashing.

8. What about Apple's mobile phone fever card?

IPhone fever may be caused by the following conditions:

(1) charging state, in which the battery will generate heat, which is a normal phenomenon.

(2) Playing large-scale mobile games or applications will take up a lot of CPU resources.

(3) Use the mobile phone when charging. It is recommended to use it after it is fully charged.

(4) Use the mobile phone in a closed environment. Because the mobile phone is turned off, the heat can't be emitted, which will lead to severe fever. It is recommended to use in a well-ventilated environment.

(5) Use the mobile phone for a long time, such as talking for a long time and playing games.

(6) Mobile phone hardware failure, it is recommended to go to after-sales outlets for detection.
