1. The mobile phone battery cannot be charged. The battery may have gone into standby mode. This is mainly because the user runs out of battery and the phone turns off automatically. The solution to this situation is to remove the battery, wait 5 minutes, then reinstall the battery. Use the data cable to connect the Xiaomi phone to the computer, then turn it on again after 30 minutes.
2. If the cell phone battery suddenly fails to charge, you should check whether a regular original charger is used. If you use another charger, you need to check if there is any problem with the charger or the charger interface is damaged. Replacing with a new charger can resolve this situation.
3. If the mobile phone can be connected to the charger for charging, but it is not fully charged, I need to check if there is a problem with it.ec the mobile telephone system. Sometimes some battery management software is installed on the mobile phone to protect the battery, and if there is any problem with these software, the battery will not be fully charged. You can use a universal charger to charge the cell phone battery and check if the battery is damaged. If the battery can be fully charged with a universal charger, then the phone system needs to be repaired or flashed.
4. In addition to the above situations, loose charging interface of the mobile phone, short circuit of the internal charging circuit of the mobile phone, etc. may occur. can also prevent the mobile phone battery from charging. . In this case, the mobile phone should be sent to a professional after-sales repair center for maintenance.
Why does my phone always stop charging when it's half charged?
Whencell phone battery is used for a long time, the power decreases. Cell phone batteries usually have a battery protection circuit. When the battery is fully charged, the protection will be activated to prevent the battery from overcharging. Likewise, when the battery power is too low and the voltage is too low, the protection will be activated. to prevent excessive battery discharge. At this time you need to activate the battery.
Situations in which the cell phone battery cannot be charged and needs to be activated:
1. The battery charges very quickly, taking over an hour or even less than an hour to charge. The display level has reached 100%;
2. After charging reaches 100%, when the charging plug is unplugged and plugged in again, the charging display level drops to 50.%-80%;
3. Once charginge reached 100%, the mobile phone battery level is not full when turned on, only 3 or 4 bars;
4. the first 2 or 3 bars of the cell phone battery are very unsustainable, and the last bars are less durable than the previous ones. Very durable;
5. The mobile phone battery has been stored for too long, and the power of the mobile phone battery is automatically exhausted during the storage process (the mobile phone battery consumes power, mainly because the protective plate on the inside the battery consumes energy), the chemicals have lost their activity in most cases. It will be fine if you charge it for a while. If it still can't be charged, you need to activate the battery;
6. If the mobile phone battery is too discharged, the battery protection board will disconnect the power supply and power.arge when the battery voltage is reached. lower than 2.5V, and the battery will activate the protection setting. At this time you need to activate the battery;
7. When the cell phone lithium battery starts to age, usually it shows that the battery is full when charging, but it quickly shows that it is discharged as soon as it is used. This type of battery needs to be repaired and activated!
The cell phone battery is fully charged. The reasons for charging failure can be divided into two categories: internal battery reasons and external battery reasons.
1. Internal reasons of battery:
The battery of a cell phone is usually a combination of several batteries. If there is a battery without voltage in the combined battery, there is one. will be a problem charging part of the battery that cannot be recharged.
The baterie zero voltage is either a defective product itself, which has not reached the corresponding rated capacity and voltage value when it leaves the factory, or it has reached the end of its life due to a long lifespan. Eventually, the capacity is exhausted and the voltage drops to zero.
Solution: Go to a regular cell phone repair center to replace the battery.
2. External battery reasons:
(1) The charger is not suitable for the battery. The unmatched charger will cause too large instantaneous current when charging lithium. Battery At this time, the overcurrent protection of the lithium battery will be implemented and charging will be suspended.
(2) The internal charging circuit of the mobile phone is defective and cannot be charged normally.
(3) The contact points of the battery electrodes are contaminated, making the resistance too high. DuringWhen charging, the system thinks the battery is full and stops charging.
Solution: Replace the original charger and use an eraser to clean the battery electrode contact points. If there is a problem with the phone, it must be repaired in time.
Detailed information
Knowledge of mobile phone battery maintenance
1. The battery charging time does not need to be too long. long, it can be removed when full.
2. It is best to only use the charger originally provided by the manufacturer when purchasing the phone.
3. Battery contacts should not come into contact with metal or oily accessories, and be careful to avoid moisture.
4. Do not immerse the battery in water or throw it into a fire.
5. Do not place the battery next to low or high temperature objects, such as refrigerators and kitchens.sinières.
6. Please use special facilities when handling batteries.
7. If you need to replace the battery, please only use the same type of battery.
8. Battery life is calculated based on charge and discharge cycles.
