What's the matter if the mobile phone can't be charged

4hw.org: now people are more and more dependent on smart phones. How can they bear when they encounter a mobile phone that can't be charged? They are worried and don't know what to do. In fact, first find out the reason why the mobile phone can't be charged, and then solve the charging problem. Let's have a look!

I. what's the matter if the mobile phone can't be charged

1. The mobile phone can't be charged. Of course, we need to find out what's 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 troubleshooting

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 charging. I take Android system as an example. There is a file in the Android system log that records battery information. If the battery information is wrong, the phone will not be charged.

What should I do if I can't get my cell phone in

1. When the mobile phone fails to charge the mobile phone through the USB data line, it is recommended to remove the battery and use the universal charger to charge the battery separately. The reason for adopting this method is that when the battery is in a serious power shortage situation, the power supply module inside the mobile phone will not start normally, so it is not feasible to try to realize charging through USB data line.

2. In addition, we need to check whether the data line for mobile phone charging is intact. It is recommended that users who use mobile phone data line to charge should use the original data line as much as possible. Some mobile phone users buy a data line with the same interface in the market after losing the data line when they purchase the mobile phone, but they don't know that the internal solution of the data line of different types of mobile phones is different, and they can't charge the mobile phone normally if they use the data line with different specifications 。

3. Try not to answer or make phone calls during charging. A good habit is to turn off the phone when it is charging, so as to ensure high-quality charging effect. In the process of normal use of mobile phone, try to conduct healthy charging every time when charging, that is, when the power is less than 20%, do not wait until the power is exhausted to recharge, so as not to affect the service life of mobile phone battery.

4. For the users who use the voltage regulator converter to charge the mobile phone, they should connect the correct mains power according to the charging instructions. In general, the domestic market power is 220V, while in foreign countries, such as Japan, the market voltage is 110V. Therefore, if the mobile phone is charged abroad, it will be unable to charge normally due to insufficient voltage. The user who charges through the data line shall ensure that the normal 5V voltage is provided to the USB interface.

5. There may be a problem with the quality of the battery itself. A new battery can be replaced. Either because the battery is used too long or for some reason, the positive and negative poles of the battery are short circuited and damaged.

6. It may also be caused by the quality problem of the mobile phone itself that the mobile phone cannot be charged. In this case, it is recommended to get it to the mobile phone repair shop for repair. If the mobile phone is in the warranty period, it can be returned to the factory for repair.
