First, mobile phone charging can not go in what is going on
1, the mobile phone can not be charged, of course, we have to find which piece of the problem, only to find the problem to the right medicine. Let me go step by step from the simple to the difficult to check what the problem is.
2, first of all, the phone is connected to the charger and plugged into the plug-in board to see if it can be charged. If you can not charge, then the current possible problems are: the charger is broken, the connection line is broken, the phone interface is broken, the battery is broken, and the system problem is then excluded
3, change a cable or change the charging plug, and then charge to see if you can rush into the electricity, if the rush into the electricity, it proves that this is the problem, change a cable, or change the charging plug. When the charging plug is changed, pay attention to the same parameters as the current and voltage of the original charging plug of your phone to prevent harm to the phone. If you can't rush, the possible problems are: mobile phone interface problems, battery problems, system problems
4, the battery is removed (can not be removed, don't forcibly grab it), the use of universal charge to rush, if the charge is the problem of the mobile phone charging interface, if not, then continue to investigate the possible problem: battery, system
5, change the battery to try to be able to rush into, if the battery can be charged, it is likely that the battery is scrapped. Just change the battery. If it doesn't, it's a system problem. Pay attention to the battery is best original or buy good quality business battery, I once because of a bad quality battery and broke the phone, everyone must pay attention!
6, many people do not understand how the system can affect the charge, I take the Android system as an example, the Android system has a file in the log is to record the battery information, if the battery information is wrong, it will lead to the phone can not be charged. Mobile phone charging does not go into the solution Now we must have found the problem, then how to solve it? Let me tell you how to solve it in the order of the above tests. The charger or data cable is broken: you can replace the charger or data cable. Note: Please try to choose the original replacement, so it will not cause harm to the phone. If you feel that the original is not good, you can buy a better quality charger, but pay attention to the parameters of the charger must be the same as your original. If the current is too large, it may cause damage to the mobile phone motherboard. The problem of the mobile phone interface: This is caused by the poor charging interface of the mobile phone, such as loose. Please go to the professional mobile phone shop repair, do not disassemble the machine. Battery problem: If it is a battery problem, then change the battery, battery I do not recommend buying at will, it is best to original or high-quality batteries. System rom problems: For system rom problems, please make sure that you have some experience or knowledge of mobile phone systems. You can choose to refresh the machine to try or use the following method to clear the system battery information. Make sure you have root access on your phone. I won't go into details here because of space issues, but see my other root experience. Enter recovery mode, select wipe, then wipebatterystatus, and then reboot. If your recovery is only wipedata or factoryreset, back up all the data and wipe! Hope to help you
If the phone cannot be fully charged, please first confirm whether the machine is in the case of low ambient temperature, in order to improve the durability of the battery, charging may be limited in low temperature environment, which is a normal phenomenon. It is recommended to charge the machine in a warm environment (recommended ambient temperature: 15℃-35℃). If the phone is still not fully charged, recommend:
1. Check whether the original charger is used. If not, please replace the original charger and try again.
2. Replace another power socket.
3. If the battery supports removal, reinstall the battery or replace it with another original battery and charge it again. If the above operation is invalid, it is recommended to bring the purchase invoice, repair card and machine to the after-sales service center for inspection.
