It s cold when the iPhone automatically shuts down and charges slower

1. Please make sure to use the original charger and data cable to charge the mobile phone. Please check whether the data cable, charger, charging port and socket are in poor contact, and it is recommended to plug and unplug them again.

2. Please check whether the data cable, charger, charging interface and socket are damaged in turn, and replace them if they are damaged.

3. Please check whether the temperature of your mobile phone is too high. Huawei phones are designed with overheat protection, which will stop charging when the temperature is high. It is recommended not to use the mobile phone when charging, especially for high-power operations such as playing games, watching, and surfing the Internet.

4. If the battery is completely depleted, please charge it with the original charger for 5 minutes before checking if it returns to normal.

5. If you use a power bank for charging, please check whether the output current is consistent with the original charger of the mobile phone, if it is inconsistent, it may lead to abnormal charging.

After the above operations, the problem still exists, please back up the data in advance and bring the purchase invoice to the after-sales service point for maintenance.

Possibly, Apple's explanation for this: the iPhone automatically shuts down because the weather is too cold, and its ideal temperature is between 16°C and 22°C, if the phone is turned off because of the cold, this situation is only temporary, and when the battery temperature returns to the normal operating range, its performance will return to normal.

It is normal for power consumption to increase when the weather is cold.

The iPhone charges quickly and consumes power quickly in the following ways:

1. The mobile phone system runs frequently, and too many applications are opened in the background, which makes the mobile phone consume power very quickly. At this time, it is recommended to turn on the power saving mode that comes with the Apple mobile phone, which can help close some irrelevant programs and save power consumption.

The specific steps are as follows:

1. Light up your iPhone and put it on the "Home Screen".

2. Find and open the app "Settings" that comes with your iPhone6s in the "Home Screen", and click to enter the next step.

3. Enter iPhone 6S

After the "Settings" center, turn on the "Battery" function to go to the next step.

4. Enter the "Battery" detailed management page and find the "Low Power Mode" selected in the red box.

5. Select "On" low power mode, and the battery color in the upper right corner of the screen will change to "yellow" to make the iPhone 6S seriously and effectively reduce the power consumption after upgrading to the latest system.

Second, the mobile phone battery is aging, easy to leak and run. This is also very harmful to mobile phones. It is recommended to go to the repair point or after-sales center as soon as possible to replace the new battery, which can solve the problem of fast power consumption.

3. System bugs, users report that the phone's battery is consumed too quickly after Apple's latest system update.

Fourth, it may be caused by the unreasonable use of mobile phone chargers. If you do not plug the charging head incorrectly for a long time, it may suddenly drain the battery very quickly.

In recent days, the winter temperature seems to be exceptionally low, so that many friends who use iPhones find that their iPhone charging has slowed down, or even cannot be charged. Here are the solutions to the slow charging of iPhone in winter and the solution of iPhone not charging in winter.

Reasons why the iPhone is slow charging in winter and can't be charged:

Because Apple's built-in power supply uses a lithium battery, while the iPhone's lithium battery is set up with self-protection, which is the so-called low temperature protection . This means that when the temperature is too low, the lithium metal in the battery will be deposited, and it will no longer react chemically with the substance, resulting in a short grinding circuit inside the battery. Therefore, in the cold winter and overly cold environment, users' iPhones will be charged slowly and cannot be charged.

The solution to the slow charging of the iPhone in winter and the power does not come in:

In fact, after knowing the reason why the iPhone won't charge, our solution is very simple, which is nothing more than to make our iPhone warm up.

First of all, the best temperature for the chemical reaction of the best lithium battery when charging is above 10, so it is best to charge in a warm room, otherwise it is easy to cause damage to the battery. Therefore, if users find that the iPhone cannot be charged, they can first transfer the device to a warm room for charging, that is, the iPhone is slightly warmed up and then charged (there are also hair dryers to blow the back of the machine to heat.) Secondly, if you find that the iPhone still can't be charged when it is warm, you need to see if there is a problem with the iPhone's charger.

Low temperatures slow down the discharge chemistry within the battery.

Draining power too quickly below 0 is a common problem of mobile phones. He Yanbing, a member of the Battery and Related Materials Field Committee of the Standards Committee of the China Materials and Testing Group and an associate researcher at the Shenzhen International Graduate School of Tsinghua University, said.

At present, most of the mobile phone batteries on the market use lithium batteries, lithium batteries are chemical batteries, and their discharge is also a chemical reaction process. The negative electrode of the lithium battery is removed from the lithium ions through a chemical reaction, and the lithium ions are transported and embedded into the positive electrode through the electrolyte solution, which generates an electric current to power the mobile phone. The discharge performance of the battery depends not only on the positive and negative electrode materials and electrolyte solutions, but also on the discharge temperature and current of the battery.

At low temperatures, the viscosity of the electrolyte solution increases, resulting in a decrease in the ability of lithium ions to pass through the solution, a decrease in activity, an increase in resistance, and a decrease in the discharge voltage of the battery, thereby reducing the usable capacity of the battery and making the mobile phone consume faster.

Method 1: Put the mobile phone into the pocket with a warm baby, and the power loss of the Apple mobile phone will be alleviated when the temperature rises.

Method 2: Carry a power bank. The weather is too cold, and the iPhone is easy to turn off the power, so you can carry the power bank with you to avoid the phone being unusable in an emergency.

Method 3: Replace the battery. The aging of the battery will reduce the battery capacity and increase the rate of power loss, so the battery can be replaced directly.

The reason why the iPhone loses power quickly when the weather is cold :

1. Protection mechanism Many people have encountered that Apple's mobile phone will jump in the cold winter, that is to say, the mobile phone may still have 50% of the power in the last second, and it will jump below 20% in a few minutes, which will affect normal use very much. And the biggest reason for this is the protection mechanism set up by the Apple phone itself. Apple mobile phones use lithium batteries, and the ideal working environment temperature of lithium batteries is 16 -22, when the ambient temperature is too high or too low, the working performance of lithium batteries will be greatly affected.

Compared with other brands of mobile phones, Apple's mobile phone has a stricter control of the temperature range, so when the chip of the Apple mobile phone recognizes that the ambient temperature is too low, it will automatically activate the protection mechanism to avoid the serious impact of low temperature on the battery, so it will naturally jump out seriously.

2. Aging battery If the power loss of the Apple mobile phone is very, very serious when the weather is cold, which has seriously affected the normal use, then the influencing factors are most likely because the battery has aged seriously in addition to the protection mechanism. For this case, you can turn on the phone to see how the battery capacity is, if the capacity is already relatively low, you need to replace the battery in time.

When the surrounding environment is too low, the chemical reaction rate of the electrolyte decreases, and the current formed decreases, resulting in a relative reduction in the available power of the battery, and the battery life of the mobile phone is reduced.

When charging at low temperatures, the phone software will reduce the charging current to protect the battery. If you want to charge your phone or charge it faster, move it to a warm place indoors to charge it, or wait for it to warm up before charging.

The characteristics of lithium-ion batteries determine that their capacity decreases at low temperatures. Therefore, the use of mobile phones in cold environments is manifested in a significant reduction in battery life, and the reason why electric vehicles ride in winter is shorter than in other seasons.

This has something to do with Apple's crafting materials, systems, as we all know:

1.The iPhone system is stable and runs fast;

2.It's easy to freeze and shut down when it's cold;

3.Do not operate your iPhone in a very cold environment.

Apple's battery is small, the battery is not easy to use in winter, especially cold places can not be put outside, it will shorten the battery life, this is a normal phenomenon, it is recommended to bring a power bank, if you are troublesome, change the battery, how to say that the new will be better.

Apple's common problem is like this, and it's good to put it in that bed when charging. When you first arrive at your hometown, you can charge it faster, and you can use it for a longer time if you use ** in a warm place, and this apple is like this.

If the phone is too cold, it will also cause it to not be charged, put it in your pocket, don't always take it out, Apple phones are also afraid of cold.

After the weather is cold, all mobile phones are like this, and it is normal for the power consumption to increase when the weather is cold.

The battery capacity of the Apple mobile phone is small, which is normal.

Electronics are such a thing as inexplicable, and the battery may wear out.

There is a problem with the battery, and the battery needs to be replaced, or the phone is replaced.

If so, then waiting for the hot weather will be even worse.

It's normal, the first day with a mobile phone, friend.

See if there's a problem with the battery.

After the weather is cold, all mobile phones are like this, when the weather is cold, the power consumption will be after the cold, all mobile phones are like this, when the weather is cold, the power consumption will increase, it is normal to be large, it is normal to be cold, all mobile phones are like this, when the weather is cold, the power consumption will be after the cold, all mobile phones are like this, when the weather is cold, the power consumption will increase, it is normal to be large, it is normal after the cold, All mobile phones are like this, when the weather is cold, the power consumption will increase, it is normal after the weather is cold, all mobile phones are like this, when the weather is cold, the power consumption will increase when the weather is cold, it is normal, it is normal to be big, it is normal to be cold, all mobile phones are like this, the power consumption will increase when the weather is cold, it is normal, it is normal.

Summary. Hello pro Apple mobile phone suddenly found that the charging is particularly slow Reason: data cable problem; system issues; The charging port is in dust; hardware issues; Temperature issues, too high or too low are difficult to charge.

Hello pro Ping dismantled the fruit and pointed to Kai's mobile phone suddenly found that the charging was particularly slow, the reason: data cable problem; system issues; The charging port is in the dust; hardware issues; Temperature issues, too high or too low are difficult to charge.

There is no such thing as slower charging speed when it is turned off, but it will be faster to charge when it is turned off than when it is turned on. When the charger is turned on and charged, the output current of the charger is larger than the output current of the shutdown charging, and the lithium battery receives the charging current of the charger on the one hand, and on the other hand, it provides the power supply required by the whole machine. When the charger is turned off and charged, the charger only provides charging current to the lithium battery, and the amount of charging current is not affected at all, ensuring a stable and sufficient current, so the shutdown charging is faster than the boot charging.

The slowness may be related to the problem mentioned above.

data cable issues; It is a question of the system of Bo Dan; The charging port is in dust; hardware issues; Temperature issues, too high or too low are difficult to charge. The package delay is caused by some problems such as aging of the trapped battery, unstable voltage, too small power, and too low temperature.

1 The charging head components are damaged or the charging head is fake.

2 The cable is damaged or the cable is fake.

3 Damaged battery (because the iPhone 6 phone has been on the market for less than a year, the problem of battery damage is rare).

4. Broken tail plug (this is even rarer).

You can follow the above four items to eliminate one by one to easily find the problem, try to change the charging head first, if it is still slow, try to change it first, it is very easy to find the problem.

Battery-saving tips

Tip 1: Enable the "grayscale" function on your phone

First of all, open the phone's [Settings] - General - Accessibility [Function] in turn, then find the [Grayscale] option on the page, and turn on the button on the right. After setting it in this way, the visual effects of all interfaces of the mobile phone will become black and white, which is the meaning of "grayscale". From color to black and white, the power consumption of the mobile phone can be greatly saved, but the visual effect will be much worse.

However, it can still be used in some special moments.

Tip 2: Turn off some features that you don't use often

1. Turn off Siri, the voice assistant.

Most of my friends generally don't use the Siri function of Apple's voice assistant on their phones, so they can choose to turn it off. On the [Settings] page of your phone, click to open the [Siri] option, and then select Off. This is shown in the figure below.

2. Turn off WiFi and Bluetooth.

When we don't need to use wifi and bluetooth, it's best to keep them off, because if they are on, they will search from time to time, which will speed up the battery consumption of the phone.

3. Turn off the push function of mail, contacts and calendar.

As long as you successfully log in to your email account on iPhone6, the system will push new emails in real time by default, which consumes a lot of power. If you don't often send and receive emails on your phone, it is recommended to turn off this push function. Turn on the [Settings] - Mail, Contacts, Calendars - Get New Data option in turn, and turn off real-time push.

5. Turn off the location service function.

The location services feature is very battery intensive. We can go to the [Privacy] interface of [Settings] to turn off the location function of some apps that are not commonly used. In particular, some functions such as [IAD Advertisement], "Frequently Visited Locations", and "Diagnosis and Usage" in the system service can also be disabled.

6. Turn off iCloud Drive and Stream.

7. Turn off background app refresh.

We turn on the [Settings] - General - Background App Refresh] interface, close the app to refresh the content in the background, which can save the phone's battery well.

Tip 3: Reduce the brightness of your phone's screen

iPhone6 phones can turn on to automatically adjust the screen brightness, but sometimes the automatic adjustment is too bright and causes battery consumption. We can turn off the [Auto Brightness] button in the [Settings] - Screen Display & Brightness option. Then reduce the brightness of the screen as much as possible according to your needs.
