What's the matter when the mobile phone can't be charged in winter
4hw.com.cn: now it's no exaggeration to say that smart phones have become a part of our life. Even many friends don't leave their mobile phones. Many friends don't charge their mobile phones in winter. They look very worried and don't know what to do. Let's have a look!
1、 What's going on if the phone doesn't charge
1. The temperature is low in winter. In many areas below zero, the smartphone battery has a protection mechanism. When the phone is below zero, it will not rush in. The solution is to warm the phone.
2. The mobile phone can't be charged. Of course, we have to find out which piece is wrong. Only when we find the problem can we apply the medicine to the case. Next, I'll step by step from simple to difficult inspection.
First, connect the mobile phone to the charger and plug it into the plug-in board to see if it can be charged. If it cannot be charged, the possible problems at present are:
The charger is broken, the connecting cable is broken, the mobile phone interface is broken, the battery is broken, and there are system problems
Then eliminate it
Change a connecting wire or a charging plug, and then charge again to see if it can charge. If it can charge, it will prove to be the problem. Change a wire or a charging plug. When changing the charging plug, pay attention to the same parameters as the current and voltage of the original charging plug of your mobile phone to prevent harm to the mobile phone. If not, the possible problem is:
Mobile phone interface problem, battery problem, system problem
4. Remove the battery (don't force it to be removed if it can't be removed) and use universal charging to flush it. If it is flushed, it is the problem of the mobile phone charging interface. If not, continue to check
Possible problems: battery, system
5. Try changing the battery to see if it can be charged. If the battery can be charged, it is likely that this battery is scrapped. Just change the battery. If it still can't be charged, it can only be a system problem. Note that the battery should be original or buy a high-quality business battery. I once broke 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 failure to charge. I take the 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 mobile phone will not charge.
What if the phone doesn't rush in
1. When the mobile phone cannot be charged through the USB data cable, it is recommended to remove the battery and use a universal charger to charge the battery separately. The reason for adopting this method is that when the battery is seriously out of power, the power supply module inside the mobile phone will not start normally. Therefore, the method of trying to charge through USB data cable will not be feasible.
2. In addition, we need to check whether the data cable for mobile phone charging is intact. It is recommended that users who use the mobile phone data line to charge with the original data line as much as possible. Some mobile phone users casually buy a data line with the same interface in the market after the data line they are equipped with is lost, but they do not know that the internal solutions of data lines of different types of mobile phones are different, Of course, the mobile phone cannot be charged normally with an irregular data cable.
3. Try not to answer or make calls during charging. A good habit is to turn off the mobile phone when charging, so as to ensure high-quality charging effect. In the normal process of using the mobile phone, try to charge healthily every time you charge, that is, when the power is less than 20%, do not wait until the power is exhausted, so as not to affect the service life of the mobile phone battery.
4. For users who use the voltage regulator converter to charge the mobile phone, connect the correct mains power for charging according to the requirements of the charging manual. In general, the domestic mains voltage is 220V, while in foreign countries, such as Japan, the mains voltage is 110V. Therefore, if the mobile phone is charged abroad, it will not be charged normally due to insufficient voltage. Users who charge through the data line should 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. You can replace it with a new battery. Or the battery is damaged because it has been used for too long or the positive and negative poles of the battery are short circuited for some reason.
6. The failure to charge the mobile phone may also be caused by the quality problem of the mobile phone itself. In such cases, it is recommended to take 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.
