The charging of Huawei nova Youth Edition suddenly slowed down, and it was useless to change the cha

Hello questioner! In fact, it's not that the mobile phone responds slowly, but when the mobile phone is charging, the screen is somewhat affected by static electricity, so I didn't sense and react, you can refer to it.

Charging is a Chinese word, pinyin chōng diàn, which refers to 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. Now, there are extensions such as study, work, etc.

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.

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]

During the warranty period, bring the receipt and warranty card to the after-sales service or merchant.

This one is biased towards the charger issue.

The recommendations are as follows:1Replace the charger with the same power for testing, 2Check whether the charging interface is abnormal;

3.If it will turn off and charge, try it.

4.If it cannot be solved, it can only be sent to the repair service station for repair.

Charge off and charge on. Charge in a few days. I can't find after-sales.

Your situation should be a hardware problem of the mobile phone, it is recommended to bring the mobile phone to the nearest mobile phone brand corresponding after-sales outlets for maintenance.

If it is a failure caused by the quality of the mobile phone, you can enjoy free repair during the warranty period.

Low temperatures can affect battery activity, resulting in slow charging. If the ambient temperature is normal (0 to 45) and the charging is slow, it is recommended that you try the following:

1. Use the original charger to charge, and check whether it takes a long time to be fully charged when the machine is turned off and charged;

2. If it only appears when charging is turned on, it is recommended to close all background programs before charging (drop-down menu, click one-click to clean);

3. Replace the power socket and try to charge;

4. After backing up important data (contacts, multiple files, etc.), and then restore factory settings (Settings - System "More" - Factory Reset, please do not check "Clear completely").

5. If there is still slow charging, it should be that the battery is faulty, and it is recommended to replace the battery for testing.

If the problem still exists, please bring the purchase invoice, warranty card and machine to the customer service center for testing, and the professional engineer will solve it for you.

The phone cannot be charged, and there may be the following problems:

1. It is recommended that you use the standard charger and charging cable for charging.

2. If your mobile phone has not been used for a long time, or you have not charged your mobile phone in time after turning off the low battery, the battery may be over-discharged, it is recommended that you connect the charger and charge for more than 30 minutes to see if the mobile phone responds.

3. If your mobile phone can be turned on, please confirm whether there is any poor contact or damage to the charging equipmentaPlease check the interface between the charging cable and the mobile phone, and whether the charging cable is fully plugged in;

b.Please check whether the data cable, charger and socket are not in good contact, and it is recommended to plug and unplug them again;

c.Please check whether the connector and jack are clean, if you find dust, it is recommended to clean it with a brush, and then recharge it to confirm;

d.Please check whether the cable, charger and socket are broken, and if damaged, stop using and replace them.

4. It is recommended that you change to other chargers that can be charged normally and try to charge them. If it can be charged normally after replacing the charger, it may be a fault of the charger and data cable, and if it cannot be charged, it may be a problem with the phone itself. We recommend that you back up your data in advance, bring your phone, charger, cable, and proof of purchase to a nearby Huawei Customer Service Center for testing.

The phone cannot be charged from the following aspects:

1. Charger problem. Consider trying with other chargers, including a computer.

2. Problems with charging cables and interfaces. Try a different cable.

3. Problems with the charging control circuit of the mobile phone, as well as the problem of the mobile phone battery. Both of these have to be sent for repair.

Don't wait until the battery is low to charge the battery, try to charge it as you go, you can extend the life of the battery.

1. Try to use the original charger to charge the mobile phone. Try to avoid using your phone while charging.

2. Remove the charger in time after the battery is fully charged to avoid long-term charging, otherwise the battery may be damaged or the life of the charger may be shortened. The theoretical charging time of the HUAWEI Nova Youth Edition is about 100 minutes. If it is charged at 20% or more, it is normal to be fully charged in one hour.

In this case, it should be that the mobile phone battery is not durable, and it is recommended that the landlord can go to the after-sales service to test the mobile phone battery.

Answer, from the description to analyze, it shows that the life of the battery is almost up, it is recommended to replace a battery.
