There are many reasons why cell phone cannot be charged, and there are two main categories: system and hardware. The system is the reason for the mobile phone ROM, and the hardware is the phone charger, phone battery, and other issues.
What can I do if my phone charger cannot be charged?
How to find what is wrong
Step 1. The mobile phone can’t charge, but of course, it’s going to be a problem. First, the phone is connected to the charger and plugged into the card to see if it can be charged. If it can’t be recharged, then the possible problems are:
(1) The charger is broken
(2) The connection line is broken
(3) The phone interface is broken
(4) The battery is broken
(5) System issues
(6) Then remove it
Step 2. Change the connection cable or change the charging plug, and then recharge it to see if it can rush into the electricity. If the rush of electricity, it proves to be the problem, change the root line, or change the charging plug on it. Pay attention to the same parameters as the current and voltage of the original charging plug of the mobile phone when changing the charging plug. Prevent damage to the phone. If not, the possible problems are:
(1) Problems with the mobile phone interface
(2) Battery problem
(3) System problems
Step 3. Remove the battery. Use universal charger to flush, if OK, it is the problem of mobile phone charging interface, if not, then continue troubleshooting, there may be problems:
Step 4. Try another battery. If you can charge after changing the battery, it is likely that the battery is scrapped. Change the battery. If it still does not work, then this can only be a system problem. Pay attention to choose the original cell phone battery.
Step 5. Many people do not understand how the system will affect charging. Using the Android system as an example, there is a file in the Android system’s log that records the battery information. If the battery information is incorrect, the mobile phone will not be charged.
