Xiaomi mobile phone charging abnormal, how to solve it?

If the Xiaomi phone is charging abnormally, it should be powered off in time and do not continue to use it. Here's a general workaround:

1. If you purchased it through the channel of Xiaomi's official website, then log in directly to Xiaomi's official website and contact customer service to deal with the problem.

2. If it is not purchased through the official website channel, then go directly to the store or network operator to request after-sales service.

3. You can also go to the electrical maintenance location to repair at your own expense.

"Charging" is the process of replenishing power to a device such as a battery. The principle is to let the direct current pass in the opposite direction of the discharge, so that the active substances in the battery can resume their effects. Charging behavior of devices such as printers. Now, there are extensions such as study, work, etc.

Principle. The working process of the battery receiving electrical energy from the external circuit and converting it into the chemical energy of the battery. After the energy of the battery is consumed by discharge, it can be restored by charging and can be re-discharged, constituting a charge-discharge cycle.

Generally, it is charged with DC current (also with asymmetric AC current or pulse current). In different cases, different charging methods are used, such as constant current charging, constant voltage charging, floating charging, trickle charging, emergency charging or a combination of these methods.

According to the formula of electricity = voltage * current * time, in the case of fixed power, the charging time can only be shortened by increasing the voltage or increasing the current.

Low-voltage charging: low-voltage high-current mode, increasing current, introducing MCU monolithic microcomputers in both charger circuits and battery circuits to replace step-down circuits. Under the premise of low voltage and high current, the output of the current with segmented cross-flow is realized through the open voltage loop.

High-voltage charging: high-voltage and low-current mode, increasing voltage, requires multiple step-down circuits to be designed in the charging circuit. In general, the charging process of mobile phones is to first step down the 220V civil voltage to the 5V charger voltage, and then the 5V charger voltage to the battery voltage.

There is a step-down circuit in both the charger and the mobile phone circuit, so when charging, the charger will heat up, and the phone will also heat up. Heating brings a bad experience and affects the safety of the battery.

The reasons why Xiaomi phones can't be charged are as follows: the phone is sleeping, the charging port is dusty, and the charging cable is damaged.

1. The battery of the Xiaomi mobile phone cannot be charged when the mobile phone is dormant, it may be that the battery has entered a dormant state, which is mostly caused by the user running out of power and the mobile phone automatically shutting down.

2. If there is dust in the mobile phone charging port, it may be that too much dust has been deposited in the mobile phone charging port, and the accumulation will block the charging port, resulting in inability to charge or poor contact.

3. The charging cable is damaged, and many friends will have the habit of playing with the mobile phone while charging, so this operation will cause the data cable to be easily broken, and there is no way to charge it successfully.

Features of Xiaomi mobile phones:

1. Processor.

In addition to the Xiaomi Mi 3 mobile version, Xiaomi 5C, Xiaomi Play are equipped with Qualcomm Snapdragon processors, with high performance, low power consumption, intelligent and comprehensive connection performance, Xiaomi 6 is the first mobile phone product based on Qualcomm Snapdragon 835 platform released in China.

2、miui。

MIUI (Mi Pome) is a third-party mobile phone operating system based on the deep optimization of the Android system, customization, and development, based on the Android system, it has been deeply customized for Chinese users, and the MIUI development team will communicate directly with users on the Xiaomi community, receive user feedback and continue to improve the system, and let users participate in the development of the system.

3. Xiao Ai.

Xiao Ai is an artificial intelligence (AI) released by Xiaomi on July 26, 2017 Xiao Ai can support continuous dialogue, active interaction, and has the ability of multi-modal interaction, the main functions include full-scene intelligent collaboration, conversational active intelligence, customized emotional voice, multi-modal fusion interaction and smart learning assistant.

If the phone suddenly can't be charged, it may be that the battery is already there.

It's out of order.

Now mobile phones.

Generally, the battery is not durable, and the other parts are fine.

The phone cannot be charged, check the charging port and data cable.

The reason why the battery of Huawei mobile phone cannot be charged is as follows:

1. Check whether the charger is normal.

Usually when encountering a mobile phone that cannot be charged, the first thing to consider is whether the charger is normal, whether the charging cable is damaged, whether the charging head is faulty, and whether the contact is poor. If your own charger is damaged, try using a different charger to check if it can be charged.

2. Check whether there is a problem with the data cable, and the user replaces the new data cable to test whether it is charged normally 3. Check whether the charging hole of the mobile phone is damaged.

To rule out whether the charger is normal, then consider whether the charging hole is damaged. Check whether there are any foreign objects blocked in the charging hole and whether the metal contacts are damaged.

4. Consider whether the mobile phone battery is damaged.

Exclude both of the above cases. That's a problem with the phone's battery. If it is really a battery problem, then it is possible that the phone is over-discharged, causing the battery to sleep. It is recommended to take it to a mobile phone repair shop for repair.

Hello! Don't over-discharge the battery, an experience, my Redmi phone and the Redmi phones of friends around me have encountered several times that cannot be charged, and the use history is investigated, most of the battery is too clean before it starts charging (maybe it leads to battery hibernation). Take out the battery and put it in again for charging after a while (if it doesn't work once, try a few more times), and the problem will be solved.

If it really doesn't work, go get a seat charger or universal charger to charge.

Redmi phone shows the cause of abnormal charging and how to solve it:

1. It may be that a non-original charger is used, and the original data cable and charger are used for charging.

2. The firmware version is low, you can try the firmware upgrade.

The charger is not properly connected.

The line connection is unstable.

If the Xiaomi power bank is charging abnormally, you can directly ask Xiaomi customer service about the situation.

Xiaomi power bank is a year of after-sales,If you have any questions, you can directly consult Xiaomi customer service,Electronic products are disassembled and not guaranteed,It's best not to disassemble the machine casually。

The common problem is that the overcharge causes the power bank to enter the charging protection state, at this time it is not charged, and the power supply can be discharged by plugging it into the power bank for 2 hours to charge.
