What is the reason why Huawei mobile phone charges slowly
< br >
NO.1 The charging plug is not selected correctly
< br >
When we buy a new smart terminal, we should pay attention to the explanation of charging on the manual. In fact, there is a lot of knowledge in this. If you use the plug of the iPhone to charge the iPad, you will find that the charging speed is not generally slow; If you use a high-power plug to charge a low-power mobile phone, it will speed up the charging speed, which may have a safety hazard for the mobile phone battery. Therefore, it is best to use the original official charging plug.

NO.2 Charging wires is too messy
< br >
Do not assume that all USB charging cables are the same, they do not support the same current. If you find that the charging speed is slow, check other charging devices and do not find the problem, then it is likely that you did not choose the right charging cable. Therefore, we try to use the original charging cable to charge the device, and it is best to make a mark on several charging cables that look very similar.

NO.3 Inappropriate charging temperature
< br >
Originally, in a low-temperature environment, the low-temperature protection mechanism of lithium batteries will cause no chemical reaction of substances in the battery, so it can not be charged or the charging speed is slowed down. In a warmer environment, lithium batteries can work well, but it should be noted that the overheating environment will also cause the scrap of lithium batteries.

NO.4 Annoying dust
< br >
Friends, do not underestimate the mobile phone cleaning this matter. If the charging port is blocked by annoying dust, it will cause poor contact, not only the charging speed is slow, but more seriously, the phone may not be able to charge. Fortunately, the bare charging port is also relatively easy to clean up by itself, take a needle or toothpick to carefully clean up the charging port, or bring a dust plug for the charging port, which can solve the dust problem.
There are many reasons for slow charging, which can be investigated according to the following steps:
1, may not use the standard charger and data cable, it is recommended to try after the standard configuration. Charging with a mobile power supply, or connecting to a computer USB port will also charge slowly.
2. When charging, the charger, data cable, and mobile phone charging interface are not in contact, or there is dust in the connector and jack, which may lead to slow charging. You can plug and remove the charger several times, wipe it with alcohol or clean it with a brush. If alcohol wipe, need to wait for alcohol to dry, and then re-charge.
3, in the charging process, the temperature of the mobile phone will change to a certain extent, especially when charging the mobile phone also runs some programs, the temperature will rise significantly, the charging current will gradually decrease when heating, the charging speed will slow down until it is full. It is recommended to wait until the temperature of the phone decreases before charging it, and close the background applications.
4, it is recommended not to use the mobile phone when charging, especially close the video, games and other applications with high power consumption, otherwise part of the charger input current to offset the power consumption of the mobile phone, the current to the battery will be reduced, and the charging speed will be slow.
5, usually the mobile phone battery is low charging speed is relatively fast, when the charging reaches more than 80%, the battery power is close to full power. In order to ensure the safety of use and extend the battery life, when the battery is quickly full, the charging current output of the charger will gradually decrease, and the charging speed will slow down until it is full.
