What are the reasons why the battery of the mobile phone cannot be charged
What are the reasons why the battery of the mobile phone cannot be charged
Do you know the reason why the battery of the mobile phone cannot be charged?
First, connect the mobile phone to the charger and insert the plug to see if it can be charged. If it does not work, the problem may be a bad charger, a bad connection, a bad port, a dead battery or a system problem.
What if the battery of the mobile phone is not charging? Use the elimination method to determine the cause of the problem and use the medicine correctly. If it is a battery problem, you can replace the original battery; if it is a charging cable problem, replace the charging cable.
1. Why the mobile phone battery cannot be charged
1. First, connect the mobile phone to the charger, insert the plug-in board, and see if it can be charged. Assuming it does not work, the problem may be that the charger is broken, the connection is broken, the port is broken, the battery is dead, and the system is faulty.
2. To replace a connecting cable, you can replace the charging plug first, and then charge it again to see if it can be charged to electricity. If it is charged to electricity, it proves to be the problem. Replace a wire, or replace the charging plug. Pay attention to the change of the charging plug when charging, and note that the current and voltage parameters are the same as the original mobile phone charging plug to avoid damage to the device. Assuming it does not work, the possible problems are: a problem with the phone interface, a problem with the battery, and a problem with the system.
3. The battery will be removed (don't grab and remove forcefully when you can't remove it), use universal charging to charge, assuming that the charging interface is a problem with the phone, if not, then continue to investigate. There may be problems: battery, system.
4. Replace the battery to see if it can be accessed. Assuming that the battery can be charged, it is likely that the battery is scrapped. Just change the battery. Assuming it still doesn't work, this is just a system problem. Remember, the battery should be original.
5. Many people don't understand how this system affects charging. Take the android system as an example.
2. How to deal with mobile phone battery charging
1. The data cable of the charger may be broken: there may be no problem with the data cable if the charger is replaced. Note: Please try to replace the original one to avoid damage to the phone. If you think the original is not good, you can buy a better quality charger, but please note that the parameters of the charger must be the same as your original. Assuming that too much current may damage the motherboard of the phone.
2. Mobile phone interface problem: This is caused by a bad mobile phone charging interface, such as looseness. Please go to a professional mobile phone shop for repairs, do not disassemble the machine.
3. Battery problem: If the battery problem is confirmed, replace the battery, preferably an original battery or a high-quality battery.
4. System ROM issues: Regarding system ROM issues, please ensure that you have a certain amount of relevant experience or a certain amount of mobile phone system knowledge. You can choose to try again by sliding the machine, maybe use the following method to clear the battery information in the system. To ensure that your phone has root privileges, enter the recovery mode, select clear, then clear the battery status, and restart. Suppose your recovery is only to erase data or factory reset. Please backup all data and erase again.
