What s going on when the phone can t be charged?

If you are using a Huawei phone, you can follow the following methods to determine the cause of the problem:

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

The first reason: the expiration of the phone's battery life.

Most of today's mobile phones are equipped with lithium-ion batteries as energy storage devices for mobile phones, compared with lead-acid batteries, lithium batteries have the advantages of lightness, long life, low self-discharge, etc., generally speaking, the service life of lithium batteries is about 500 charging cycles, usually it can be used for 2-3 years without any problem, in this process, the power contained by the mobile phone battery will become smaller and smaller, when the service life of the mobile phone battery expires, the battery will be scrapped, resulting in the inability to charge, Therefore, we need to go to the mobile phone store to replace the new mobile phone battery.

The second reason: the phone charging port is malfunctioning.

The reason why the mobile phone cannot be charged may also be that the charging port of the mobile phone is blocked, because of our usual usage habits or placing the mobile phone at will, sometimes it will cause the mobile phone charging port to enter the confetti, particles and other foreign objects, thus blocking the charging port, resulting in the disconnection between the mobile phone and the charger and the situation that it cannot be charged.

The third reason: faulty phone charger or data cable.

The reason why the mobile phone can not be charged may also be the failure of the mobile phone charger or the failure of the power cord, generally speaking, most friends have one or two mobile phone chargers or data cables at home, when the data cable is disconnected internally, the mobile phone and the charger are also disconnected at the same time, resulting in failure to charge, or the charger is faulty, then we need to try whether other chargers and data cables can work normally, if so, directly replace the charger or data cable.

The fourth reason: the battery cannot be charged due to the long-term idle and non-use of the phone.

The speed of mobile phone replacement is very fast, basically every month there will be ** model appeared, when we buy a new mobile phone and abandon the old mobile phone, resulting in the old mobile phone for a long time to be idle, after a long time to use it again sometimes there will be a situation that can not be charged, at this time it may be because of the long-term battery loss and starvation, generally speaking, this can only replace the mobile phone battery.

The fifth reason: phone system problems.

The example of the mobile phone system failure that causes the mobile phone to not charge occurs from time to time in life, especially after updating the system, it is found that the mobile phone always remains at a percentage when charging, but the mobile phone can be used normally, at this time, it is about the system update for the mobile phone power display setting problem, then we need to restart the mobile phone to see if it returns to normal after restarting.

The sixth reason: mobile phone hardware failure.

Sometimes when we use the mobile phone, we accidentally let the mobile phone into the water, into the dust, or the motherboard and other hardware of the mobile phone malfunction, at this time there will also be a situation where the mobile phone cannot be charged, there is nothing to say about this situation, just take it to the repair shop to repair it.
