Redmi note8 Pro charging intermittently used original accessories or a bar Lightning? 15

Regarding the above problems, first check whether the power socket is in poor contact with the original charger.

Check that the original charger itself is in good order.

Check whether there is any poor contact inside the original charging data cable.

Title. Check the charging data cable plug and the mobile phone charging tail plug, whether there is poor internal contact between the two.

Condition. Check whether the battery inside the phone is normal(This inspection is best to ask a professional master, and the mobile phone can also be tested).

After the above checks, if everything is normal, then the problem may be that the charging control circuit on the motherboard is faulty.

In this case, you have to change the charger to one is that you can use other chargers at home to charge your mobile phone, if the same problem still occurs, it can only mean that there is a problem with the mobile phone. Then you have to go to the professional after-sales service for inspection and maintenance.

The original accessories will also be bad, intermittent charging may be a problem with the charging head or data cable, or it may be a problem with the charging interface, you can find a new set of or other data cables and charging heads are plugged in to give it a try, as for the charging interface, it may be that the charging interface is dusty or oxidized. It will also cause intermittent charging and poor contact, which can be used. A small cotton swab dipped in alcohol is wiped clean on the metal area on the charging port.

You can check if there is a lot of dust or dirt in the charging hole of the phone, clean it first and then try to charge it.

If the original charger is still charging intermittently, it may be that the data cable is broken or. What's wrong with your phone?

Intermittently, then consider it a problem of contact with the charging interface, it may be that the tail plug of your mobile phone has been used for a long time and there has been some damage, and it may be okay to change the tail plug.

If there is a leak, you should go directly to the mobile phone store to fix it.

What does intermittent charging look like? You can get the official Xiaomi after-sales service to test it and take a look.

This shouldn't be.,The current mobile phone seems to have this automatic power-off.,That is, after you're fully charged,Your one just won't charge anymore.,So basically there's no particularly big danger of this.。 Here's an addition to the charge.

Battery charging. PrincipleThe 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.

High-voltage charging: high-voltage and low-current mode, increasing voltage, requires multiple step-down circuits to be designed in the charging circuit. When charging, the charger will heat up, and the phone will also heat up, and the safety of the battery will be affected. [1]

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.

VOOC flash charging uses the solution of low voltage and high current to ensure safety and solve the problem of mobile phone charging and heating. [1]

Classification battery charging is mainly divided into: fast charging, ordinary charging.

No, because the charging voltage, current and power of the mobile phone are controlled by the power supply IC, and there is no such thing as "lower than its own power". And the charging power of all mobile phones will not always be the same, otherwise there will not be some models of the same size and battery capacity, the nominal 30W mobile phone is charged faster than the nominal 40W mobile phone. ”

There is no danger. It will automatically stop charging when it is full.

Today's smartphones have a full charge with an automatic power-off function.
