1. It takes about 10s for the phone and charger to interact with each other after the charger is inserted, and a slight delay is normal.

My answer is this
< br >
1. It is normal for Huawei mobile phones to charge slowly or fast sometimes, which is because the battery protection system is working.
< br >
2. Because Huawei's electronic products have very strict battery protection measures, the purpose is to extend the battery life. When the power is charged to 80%, the charging speed will be slowed down and trickle charging will be used.

3. Each charge must be full, can not be charged to half take down to play, can not charge while playing.
It is described that the mobile phone charging contact is poor, there are several possible reasons: data cable problems, may be the possibility of breaking the data cable, it is recommended to use someone else's data cable to try;
It may be the problem of the data cable connector, the connector is loose, or the entry has dirty things, you can clean it up and try;
If you still can't use someone else's data line, then it is recommended to go to the after-sales service to check whether the interface of the mobile phone is loose, or the jack of the mobile phone is broken. Then we'll have to replace the hardware.
If your battery is removable, then remove the battery and use the universal charger to charge, if it can be charged, then it is the problem of the mobile phone charging interface, if it can not be charged, then rule out the third possible cause: the mobile phone interface is broken. The same step as the previous step, if the mobile phone battery is removable, then change a battery, if it can be charged, it means that the battery is scrapped, then buy a new battery.
If you still can't charge, then there is a problem with the mobile phone system, this time you should take your mobile phone to the after-sales service to see.
