Problems with phone battery charging, who knows why?

Your phone has a minimum operating voltage setting. For example, yes.

When you put the battery out of power, add the self-discharge of the battery. The battery is easily under. For example, when it's low enough to then plug in and charge.

While the battery is charging. But the voltage hasn't reached your phone's minimum operating voltage yet. It takes a while to get there.

After a while, I rushed again and found that the phone began to show charging: This is normal.

Because the battery capacity is basically 0 after the battery is lower. Then you charge it and don't reflect. (In fact, it has already been charged) When it is recharged, it will reach the working voltage of the mobile phone. The phone will also show up.

1. The battery life is up;

2. If the life is not reached, the battery needs to be tested;

3. The mobile phone charging socket or charger plug is loose and the contact is poor;

4. Poor contact between the charger and the power supply;

5. There may be something wrong with the charger, which needs to be detected (in a quiet situation, listen carefully to whether the charger emits a small current sound when connected to the power supply, and when it is disconnected, the current sound does not disappear immediately, then the charger has a problem).

It may be that you have run out of battery, because there is no power, you can't show charging, only after a little power can be displayed! It's good for your battery!

Such questions are common. You charge the battery with a universal charge for a minute or two. Then put it on the phone and charge it directly.

It's normal. You don't have to wait for your phone to run out of power before charging it.

Reasons why the phone will charge for a while and will not charge for a while:

1. Poor contact, caused by worn and worn general threads.

2. The charger is a copycat, and the voltage is unstable.

3. The mobile phone interface is worn out or the battery is not working.

Solution: 1. Shutdown and charging test.

2. Change the charging position, and quietly eliminate the intermittent cause of socket contact and non-luck.

3. If conditions permit, replace the spare charger for testing. Or send it for repair and testing.

4. When turning on and charging, if the mobile phone is equipped with a third-party plug-in such as a rental block of the charging doctor, it is recommended to test it after uninstallation.

5. Check whether there are foreign objects in the mobile phone charging interface, such as liquid ingress, debris caused by poor contact between the mobile phone charging interface and the charger, if this situation is recommended to be repaired as soon as possible.

6. Back up your phone data (**book, SMS, **, etc.), and restore your phone to factory settings (go to phone settings - reset - factory reset).
