1. Check the charging interface, which may be grayed out.
It may be because we don't pay attention to it or often put it in the bank loan, so we only need to clear it.
2. Check the data cable and try another one.
If you have bought three data lines for five yuan on Taobao, it is estimated that the data line is faulty. Xiaobian has encountered this problem before.
3. System problems. Try restarting.
We can restart the mobile phone when the mobile phone system has been used for a long time, because the smartphone often has a strange problem that can be solved by restarting it.
4. Pay attention to the temperature problem. It is hard to charge if it is too high or too low.
If the weather is hot, your mobile phone will get hotter, so the charging will be very slow, so we can make the battery cold for a while and then charge again.
5. None of the above methods works. Please refer to the ultimate trick.
After-sales service or a battery replacement is provided. This method is only useful in the case of hardware problems.
