Being able to charge proves that the tail plug is fine, it may be that the battery is aging.

1. Check whether there is a problem with the data cable and charger first, and if so, try another one.

2. Secondly, it may be that the battery is running out of power and sleeping, so charge the phone for a longer time, and it is best to try to change the data cable.

3. If you still can't turn on the machine, there may be a problem with the battery or motherboard circuit and other parts, and it is best to contact the after-sales service to help you overhaul it.

1. The battery is damaged.

2. System failure.

3. Charger reasons or poor contact.

Solution: 1. Try to change to another charger or data cable, or clean the charging port.

2. Boot into recover mode, select advancsd advanced mode, select wipe battery, and clear battery traces.

3. Restore the factory settings to see if it is the system reason.

4. If the battery is damaged, it can only be sent for repair and replacement.

1. Cause analysis:

1. The battery is damaged. 2. System failure. 3. Charger reasons or poor contact.

Second, the solution:

1. Try to change to another charger or data cable, or clean the charging port.

2. Boot into recover mode, select advancsd advanced mode, select wipe battery, and clear battery traces.

3. Restore the factory settings to see if it is the system reason.

4. If the battery is damaged, it can only be sent for repair and replacement.

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.

There are several reasons why the Xiaomi 5S phone has charging failures:

1. The indoor socket cannot supply power normally. At this time, it is necessary to use an electric pen or a small electrical appliance with a display light to see if it is normal.

2. The charging cable is damaged or broken. At this point, you should replace the charging cable with a complete and new one.

3. The mobile phone charging port is worn and dirty, resulting in poor contact. In this case, you can wipe it with a cotton swab dipped in alcohol.

4. There is a problem with the hardware of the mobile phone. You can try restarting to reset your phone's data settings or go to the repair department for repair.

It's a matter of data cables. The reasons could be:

1: The problem of the data cable may be that the core wire in the wire is too thin, or the aluminum wire, resulting in a large resistance of the data line!

Second: the problem of the data cable connector, the contact material is not good, the electroplating is not good or the contact is poor.

Three: the data cable, wire and connector are not well welded, and the connection resistance is large.

Four: Theoretically, there is a unified industry standard for use, but some small factories are shoddy, so it is best to buy the original line.

The voltage of the charger head is not right, see what the original voltage is, go and buy a dog with the same voltage.

Buy another one and take a look. It is estimated that it is a matter of line.

1.It does not need to be fully charged for 12 hours, the lithium battery can be charged as you go, and it is recommended that you unplug it after it is fully charged.

2.It is best to turn it off and charge.

3.Try not to drain the battery, the phone will automatically shut down, over-discharge may cause the battery to sleep.

4.If you do not use the battery for a long time, please store it in a dry and low temperature environment.

A more detailed description of the problem will help netizens understand the troubles you are encountering and help you solve the problem more accurately. Thank you for supporting Xiaomi phones!

If you have a spare board, try replacing it. The second possibility is that the charging socket (both the phone and the charger are possible) are flooded. I was in a similar situation two days ago, but now I'm getting better.

In short, the most important thing is to find a way to charge the phone first, so that it does not affect the use. I hope Lao Xiao can help, if it really doesn't work, take it to repair. Repentance.
