Huawei phones sometimes charge quickly and sometimes charge normally

1. It is recommended that you use the data cable (including the fast charging cable) provided with the device, and the charger and data cable will be detected when charging, and only when the conditions are met can you enter the fast charging super fast charging mode.

a.Both the device and the charger support fast charging and super fast charging, and the charging mode is the same.

If both the phone and the charger support 9V 2A fast charging, you can enter the 9V 2A fast charging mode.

b.The calibration current of the data line meets the requirements of fast charging and super fast charging before it can enter the fast charging super fast charging mode.

For example, for 5V super fast charging, the data line current needs to be 5A and above (non-standard data cables may not be able to recognize the data cable type).

2. Please check whether there is any foreign matter or dirt in the interface.

If you find any foreign matter or dirt in the interface, it is recommended that you clean it up in time (you can use a clean soft brush, and if possible, you can take alcohol).

If you find that the connector is not fully plugged in, or if it is significantly loose, it is recommended that you reseat it again.

If none of the above methods can solve the problem, it is recommended that you back up your data in advance and bring your device (third-party applications such as QQ and WeChat need to be backed up separately), charger, data cable and purchase voucher to a nearby customer service center for testing.

There are three main reasons:

1. The charger is used incorrectly.

2. The data cable is aging.

3. The mobile phone battery is damaged.

Can't fast charge, one of the three must have a problem, in order to achieve the purpose of fast charging, chargers, data cables, and mobile phones must support fast charging.

The charger is used incorrectly, it was originally a 9 volt 2 amp charger, but it is used as a 5 volt 2 amp, so it is naturally impossible to fast charge. Because the power that the charger can support is 10 watts.

The same goes for data cables and mobile phones. If the cable or phone is used for a long time and causes damage to its interior, it will also cause the charging power to be too low, resulting in too slow charging.

There is also a situation where there is an internal judgment error, causing the charger to mistakenly believe that the phone does not support fast charging. For example, if you use a charger of a different brand than your phone, sometimes even if your phone supports fast charging, it will not be fast-charged.

There are 5 conditions for fast charging, which are the charging headCable, cable interface, internal step-down circuit (including fast charging chip on hardware + circuit and protocol on software), battery.

Huawei mobile phones are sometimes fast charging, sometimes ordinary charging, because its power supply is different from others, if it is an ordinary power supply, it cannot achieve fast charging, if it is his proprietary data cable, fast charging can be realized.

When the size is in pixels, we need to specify its fixed resolution in order to convert the size to and from the actual size in reality. For example, most web pages commonly used in the production of ** resolution is 72, that is, each inch of pixels is 72, 1 inch is equal to centimeters, then through conversion, it can be concluded that each centimeter is equal to 28 pixels; Another example is the length of 15x15 cm, which is equal to the length of 420*420 pixels.

dpi dots per inch.

Raw pixels. Because the resolution of most computer monitors can be adjusted by the computer's operating system, the pixel resolution of the display may not be an absolute measure. Modern LCD displays are designed to have a pristine resolution, which represents a perfect match between the pixels and the three-element group.

The cathode ray tube also uses red-green-blue fluorescence elements, but they do not coincide with the image pixels and cannot be compared with the pixels. ）

Pixel. For this display, the raw resolution produces the finest images. But because the user can adjust the resolution, the display must be able to display other resolutions.

Non-raw resolution must be achieved by fitting resampling on the LCD screen, using an interpolation algorithm. This can often make the screen look broken or blurry.

1.Please check whether your charger supports super fast charging, please check the output parameters of the standard charger, and judge whether the device supports charging mode according to the following information to determine whether it has entered the super fast charging mode: the icon is a single lightning, and the maximum output parameters of the standard charger are 5V 1A, 5V 2A.

Fast charging: The icon is a large and a small double lightning, and the maximum output parameters of the standard charger are 9V 2A and 10V 2A. Super Fast Charging:

The icon is a double large lightning, and the maximum output parameter of the standard charger is 10V or. 2.If your device supports Super Fast Charging mode, but the normal charging icon is displayed when charging(1), we recommend that you use the Huawei charger and data cable.

2) Please check whether there are any foreign objects or dirt in the interface, please make sure that the charging port is clean and the port connection is stable before charging your phone. If none of the above methods fail, we recommend that you back up your data in advance (third-party apps such as QQ and WeChat must be backed up separately) and bring your device, charger, data cable, and proof of purchase to a nearby Huawei Customer Service Center for testing.

Summary. Take Huawei Mate40 as an example, its operating system is EMUI11, and frequent charging with super fast charging is partially harmful to the phone. When the mobile phone is charging, the rapid flow of current will increase the temperature of the battery, thereby destroying the electrolyte of the battery, causing the battery capacity to slowly decrease.

Frequent charging will also damage the battery, and over time, you will find that the battery standby is getting shorter and shorter, and the battery life will also become shorter. Whether it is fast charging or slow charging, as long as it is charged, it will definitely cause permanent irreversible damage to the battery of the mobile phone. In order to realize the fast charging function on the mobile phone, three elements need to be met, and all three are indispensable.

Chargers, batteries, chargeics. The charger needs to meet sufficient output current as well as output voltage, because the charger traces have a large parasitic resistance, and if you want to achieve a large charging current, the on-load output voltage of the charger needs to be high.

Does Huawei Super Fast Charging and Fast Charging have an impact on mobile phones?

The charger needs to meet sufficient output current as well as output voltage, because the charger traces have a large parasitic resistance, and if you want to achieve a large charging current, the on-load output voltage of the charger needs to be high.

It depends on whether your phone supports fast charging or super fast charging.

Generally, using the original charger or the charger that matches the adaptive capacity of the mobile phone will not have a negative impact on the mobile phone.

Hope mine can help you.

1.Please confirm that your phone and charger support fast charging.

Please check the output parameters of the standard charger and check the charging mode supported by the device against the following information to determine whether Bu Luduan has entered the fast charging super fast charging mode.

Normal charging: The icon is a single lightning, and the maximum output parameters of the standard charger are 5V 1A, 5V 2A.

Fast charging: The icon is a large and a small double lightning, and the maximum output parameters of the standard charger are 9V 2A and 10V 2A.

Super fast charging: The icon is double large lightning, and the maximum output parameter of the standard charger is 10V or.

2.If your device supports Fast Charge (or Super Fast Charging) mode, but displays a normal charging icon (or fast charging icon) while charging

1) It is recommended that you use the charger and data cable recommended by Huawei.

2. Please check whether there is any foreign matter or dirt in the interface.

Please make sure that the charging port is clean and the port connection is stable before charging your phone.

If none of the above methods can solve the problem, we recommend that you back up your data in advance (third-party applications such as QQ and WeChat must be backed up separately) and bring your device, charging and noisy electrical appliances, data cables, and purchase vouchers to a nearby Huawei customer service center for testing.

Hello. This is because your phone supports fast charging.

Fast charging is also to save people time on charging.

The electric function of the charging stool specially designed by the merchant.

Very user-friendly.

The use of this function must be matched with the corresponding charging head and charging cable, so that it can be supported in this draft.

Otherwise, even if the phone can support other conditions, it can't.

First of all, check whether there is any abnormality between the data cable and the charger and the socket to connect the lead, such as poor contact, if so, replug the data cable and then charge, so that it can be restored. Secondly, if the temperature is too high, it will also affect the speed of the fast charger. Therefore, when the temperature of the Huawei phone is too high, then pause the charging first, wait for the temperature to drop slowly, and then fast charge.

Of course, the blockage of the jack and interface will also cause the Huawei fast charging charger to fail to charge quickly. Therefore, it is recommended to clean the jack and interface with a brush in time, and after cleaning, you can quickly charge it again to return to normal.

Summary. Huawei mobile phones are used by many friends, many mobile phones support fast charging, users can charge with fast charging chargers, and some small partners Huawei fast charging has become ordinary charging, what is going on, to introduce it to you. HUAWEI fast charging has become normal charging1, please check the interface between the data cable and the mobile phone, whether the data cable is fully plugged in, and try to replace the data cable.

2. Please check whether there is a problem with the mobile phone interface and go to the after-sales service for inspection and maintenance.

Huawei fast charging has become normal charging.

Huawei mobile phones are used by many small partners, many mobile phones support fast Wu Dong charging, users can charge with fast charging chargers, and some small partners Huawei fast charging has become ordinary charging, what should I do, to introduce you to the trembling birds. Cavity pure Huawei fast charging has become ordinary charging1、Please check the interface between the data cable and the mobile phone, whether the data cable is fully inserted, and try to replace the data cable. 2. Please check whether there is a problem with the mobile phone interface and go to the after-sales service for inspection and maintenance.

3. Please check whether there is dust in the connector and interface, if you find dust and other dirt, it is recommended to clean it with a brush and then recharge it.

Huawei Super Fast Charging has become normal charging? There are two main reasons why Huawei super fast charging has become ordinary charging: the first charging plug and data cable are mixed, and the second mobile phone system has a problem.

The solution also has a corresponding solution, the first one can use the original charging plug and data cable, the second can restore the factory settings, and the third can find Huawei after-sales.

First, the charging plug and data cable are mixed.

Now domestic mobile phone accessories manufacturers are not quite the same for fast charging protocols, just like Huawei mobile phones also have their own patented fast charging technology, usually super fast charging requires the original charging head and data cable to trigger, if it is not the original matching, for the sake of safety, Huawei is unable to use the highest power charging, there will be super fast charging into ordinary charging.

If this situation still occurs after using the original charging package, you can try to check whether the charging head, data cable and mobile phone connection interface are fully plugged in; Then check whether the connector and connector are clean, if you find dust and other dirt, it is recommended to clean it with a brush, and then try to charge it again.

The second type: there is a problem with the mobile phone system.

If the charger is fine, there may also be a bug in the mobile phone system, at this time we can try by restarting, if it still doesn't work, you can try to restore the factory settings after the backup.

If it doesn't work, then I recommend going to Huawei's official after-sales inspection, in the case of non-man-made damage, the warranty is free of charge.

Answer 1: After the appliance is plugged in, it takes about 10s for the mobile phone and the charger to interact with the protocol, and it is normal to have a slight delay. 2. If you use a non-standard data cable or insert a data cable too slowly, there may be abnormal protocol interaction, resulting in abnormal fast charging, so it is recommended to plug and unplug the data cable again. 3. Please confirm whether you are using the Huawei standard charger and data cable, in order to ensure the safety of charging, you can only enter the fast charging or super fast charging mode after using the Huawei standard charger and data cable.

There is a high probability that it is a problem with the charging head or data cable, and it has just experienced the situation that the charging cannot be charged, and the more it is charged, the less it is charged, and it has been successfully solved.

Phenomenon] HUAWEI Mate10 can't be charged when charging, and the more it is charged, the less it is charged, the power drops to 0% and the black screen is black, and the red breathing light flashes when connected to the charging cable, and the breathing light does not flash when the charging cable is not connected. When charging, press the lock screen button once and the screen does not respond, and no charging pattern appears. Use this original charging head and original data cable to charge the Huawei Honor 10, everything is normal.

Solution] I changed to a new original fast charger and a Samsung data cable, when I first connected it, it was still a red breathing light flashing, but when I pressed the lock screen button once, the screen appeared charging pattern, and it turned on automatically after 3-5 minutes (possibly because I had a long press on the lock screen button when charging), and everything was normal when charging.

If someone also encounters such a situation, I estimate that the probability is the problem of the data cable, my data cable is very old, I can see that the lines inside are twisted (I don't know if I can understand this picture), and the connection to the charging head is loose quite obvious, there was a time before because the data cable was too old to charge and fast charging became ordinary charging, that time I bought the original data cable again to solve.

A simple way to distinguish the authenticity of the Huawei 40w charger.

1.Weighing, in fact, there is no need to weigh it with a scale, weigh it by hand, the fake one will be much lighter than the real one.

2.The difference between the printing in the frame, the left side is real, the right side is fake, the difference is obvious, including the 3C logo below, etc.

3.The printing difference can be clearly seen in the three parts above the charger (the right side is the original**).

Fast Charge logo. supercharge".

huawei" logo, especially the letter "e" of copycat products is relatively rounded.
