What s the deal with the phone battery that doesn t charge when it s more than halfway charged?

Half of the electric charge can't be charged, so what do you want?

The reasons why the mobile phone battery cannot be charged once it is charged can be divided into two categories: internal reasons for the battery and external reasons for the battery.

1. Internal reasons for the battery:

The battery of a mobile phone is usually a combination of several batteries, and if there is a zero-voltage battery in the combined battery, there will be a failure that the charging part cannot be recharged.

The zero voltage of the battery is either a non-conforming product itself, and the corresponding nominal capacity and voltage value are not reached when leaving the factory, or it is at the end of life, due to long-term use, the capacity is consumed, and the voltage drop is zero.

Solution: Go to a regular mobile phone repair point to replace the battery.

2. External reasons for the battery:

1) The charger and the battery are not matched, and the charger that does not match will cause the instantaneous current to be too large when the lithium battery is charged, and the lithium battery will implement overcurrent protection and stop charging.

2) The internal charging circuit of the mobile phone is faulty and cannot be charged normally.

3) The electrode contact points of the battery are contaminated, causing the resistance to be too large, and the system thinks that the power is full when charging, so it stops charging.

Solution: Replace the original charger, clean the battery electrode contact points with an eraser, and send it for repair in time if there is a problem with the phone.

The mobile phone is AC charging at the beginning, that is, charging at full speed, and your mobile phone may be adjusted to trickle charging when it is halfway charged, or you are using high-power software, which will greatly reduce the charging speed, just like my 66W charger is as slow as an ordinary charger when it is a king and eats chicken.

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).

The reason why the mobile phone battery cannot be charged is:

1. Check whether the charger is normal.

Usually when encountering a mobile phone that cannot be charged, the first thing to consider is whether the charger is normal, whether the charging cable is damaged, whether the charging head is faulty, and whether the contact is poor. If your own charger is damaged, try using a different charger to check if it can be charged.

2. Check whether there is a problem with the data cable, and the user replaces the new data cable to test whether it is charging normally.

3. Check whether the charging port of the mobile phone is damaged.

To rule out whether the charger is normal, then consider whether the charging hole is damaged. Check whether there are any foreign objects blocked in the charging hole and whether the metal contacts are damaged.

4. Consider whether the mobile phone battery is damaged.

Exclude both of the above cases. That's a problem with the phone's battery. If it is really a battery problem, then it is possible that the phone is over-discharged, causing the battery to sleep. It is recommended to take it to a mobile phone repair shop for repair.

If you are using a Huawei phone and the charging is abnormal after the phone is connected to the charger, you can follow the following methods to determine the cause of the problem:

1.Please check whether the charging port is abnormal.

If there is any such phenomenon, we recommend that you back up your data in advance (WeChat QQ and other apps need to be backed up separately) and go to a nearby Huawei customer service center for cleaning and testing.

2.If your phone is charged to 80% stop charging.

Some Huawei models have added a new intelligent charging mode, which is a battery protection mechanism that effectively extends the battery life through AI intelligent charging management.

3.Please check the temperature of your phone.

When the temperature of the mobile phone is lower than 10, the mobile phone is charging slowly or does not charge, please put the mobile phone in a warmer environment to resume normal charging.

4.It is recommended to use the standard charger for charging.

It is recommended to use the charger and charging cable that come standard with your phone for charging. Non-Huawei chargers and cables may not be compatible with the phone, resulting in the phone not charging.

5.Please cross-verify.

Please replace the charger and data cable that can be charged normally, and cross-check whether the charger and data cable are faulty.

If the charger and data cable are normal, but the phone still cannot be charged, it may be a malfunction of the phone. It is recommended that you back up your data in advance (WeChat QQ and other apps need to be backed up separately) and bring your phone, charger, cable, and proof of purchase to a nearby Huawei Customer Service Center for testing.

The reasons why the mobile phone will be charged for a while and will not be charged for a while: 1. Poor socket contact. Replace the charging position to eliminate intermittent charging problems caused by poor contact with the socket.

2. There is a problem with the charger. If conditions permit, replace the original charger for testing, or send it for repair and testing. 3. Third-party plug-ins, it is recommended to test after uninstallation.

4. Check that there are foreign objects in the charging interface of the mobile phone.

Questions. One charge, one stop, one flash, one flash, and the police are called.

The reasons for abnormal charging of mobile phones are: 1. The weather temperature is too high or too low, and the battery will show that the battery is abnormal if it is affected by the weather temperature. 2. If the charger or data cable is in poor contact, it is recommended to use original accessories for mobile phone charging.

3. Playing while charging will cause abnormal charging, when it is close to being fully charged, the charging current is very small, and other operations will lead to abnormal charging, it is recommended that the mobile phone stay in standby mode or turn off for charging when charging.

Please check if the data cable is normal. The data cable looks normal on the outside, but it may have broken on the inside. The way to check is to borrow someone else's data cable to see if it can be charged.

Why don't you charge it when it reaches 80 percent?
