What's the matter if the mobile phone can't be charged? Have many people ever met this situation? The mobile phone keeps many people's secrets. If it can't be charged, is it very annoying? What's the matter with this situation? What's the good solution?
1、 What's the matter with mobile phone charging
1. Mobile phones can't be charged. Of course, we need to find out which one is wrong. Only when we find the problem can we find the right solution. Next, I'm going to step by step from simple to difficult.
2. First, connect the mobile phone to the charger and plug it in the plug-in board to see if it can be charged. If it can't be charged, the current possible problems are:
Charger broken, connecting cable broken, phone interface broken, battery broken, system problem
And then we can get rid of it
3. Change a connecting wire or a charging plug, and then recharge it to see if it can be charged. If it can be charged, it will prove to be this problem. Just change a wire or a charging plug. Pay attention to changing the charging plug with the same parameters as the current and voltage of the original charging plug of your mobile phone to prevent damage to the mobile phone. If you can't, the possible problems are:
Mobile phone interface problems, battery problems, system problems
4. Remove the battery (don't force the battery to be removed if it can't be removed), use universal charging to flush. If the problem is the charging interface of the mobile phone, if not, continue to check
Possible problems: battery, system
5. Try to change the battery to see if it can be flushed in. If the battery can be charged, it is likely that the battery is discarded. Just change the battery. If it still can't be charged, it can only be a system problem. Note that the battery is best original or buy a good quality business battery. I have damaged my mobile phone because of a poor quality battery. Everyone must pay attention!
6. Many people don't understand how the system can affect the charging. I take Android system as an example. There is a file in the Android system log that records the battery information. If the battery information is wrong, the phone will not be charged.
Solution to mobile phone charging failure
Now that we have found the problem, how can we solve it? I'll follow the order of the upper detection below to solve it.
Charger or data cable is broken: you can change the charger or data cable.
Note: please choose the original one as much as possible, so it will not cause harm to the mobile phone. If you think the original one is not good, you can buy a charger with better quality, but note that the parameters of the charger must be the same as your original one. If the current is too high, it may cause damage to the main board of the mobile phone.
The problem of mobile phone interface: This is caused by the poor charging interface of mobile phone, such as looseness. Please go to a professional mobile phone shop for maintenance, do not dismantle the machine by yourself.
Battery problem: if it's determined that it's a battery problem, replace it. I don't recommend buying batteries at will. It's better to use original or high-quality batteries.
Problems with the system ROM: for problems with the system ROM, please make sure that you have some experience in brushing or knowledge of the mobile phone system. You can choose to swipe the machine again to try or use the method below to clear the battery information of the system.
Make sure your phone gets root permission. Because of the length problem, I won't explain it in detail here. Please refer to another article about root. Enter recovery mode, select wipe, then select wipe battery status and reboot.
If your recovery only has wire data or factory reset, please back up all data in wire!
2、 What's wrong with Samsung mobile phone charging
First of all, we need to find out the reason, whether or not we used to wrap the USB cable into a circle for easy carrying. However, this often causes the internal fracture of the data cable.
Used to plug in the charger while charging while playing with the mobile phone, but this often leads to poor contact of the mobile phone charging head.
Someone asked why it could show charging?
That's because there are four USB cables, two of which are for charging, and the other two are for checking whether they are connected to the charger.
The connecting wire is in good condition, and the two charging wires are broken, so they will not be charged and show that they are charging at the same time.
If you want to know whether your USB cable can be charged, you need a professional current detection tool, which is not mentioned here
But there is also a software measurement method, as shown in the figure below. After connecting the charger, the green box shows the AC charging, but the status is' discharge ', and the power consumption is 90mA per hour
Add 935ma power every hour, indicating that USB cable and charger are good.
3、 What's wrong with Xiaomi's cell phone charging
In view of this problem, there are mainly the following situations:
1. The most common cause of charging failure of Xiaomi mobile phone is poor contact. When Xiaomi mobile phone fails to charge, try to unplug the connection between charger and mobile phone;
2. In addition, it still can't be charged after reconnection. Please try another mobile phone charger, or try to connect Xiaomi's mobile phone to the computer. If the problem is solved, it should be the charger problem. If not, it may be Xiaomi's problem. It's recommended to contact Xiaomi's official customer service or after-sales service!
3. In addition, if the millet mobile phone supports battery disassembly, you may as well try to use the seat charge or universal charge to fully charge the battery once;
