Smart phones have entered the era of universal popularity, but are you right to charge smart phones? To correctly charge smart phones, we should first have a clear understanding of the classification of smart phone batteries. Smart phone batteries can be roughly divided into nickel cadmium / nickel hydrogen batteries and lithium batteries. Before, smart phones were basically equipped with nickel cadmium and nickel hydrogen batteries. These batteries have memory effect. In the early stage of using the battery, it needs several times of complete charge and discharge to activate the battery, so as to optimize the performance of the battery. But now the smart phones on the market are basically equipped with lithium batteries. Unlike nickel cadmium and nickel hydrogen batteries, lithium batteries have little memory effect and do not need to be activated, so multiple charge and discharge are redundant.
How to charge the lithium battery cell phone correctly when it is used at ordinary times?
Method / step 1:
Read the instructions carefully.
The manual generally has the charging method of the mobile phone. This manual is of great value as an official reference.
Method / step 2:
Try to use the original charger of the mobile phone.
The original charger is completely designed for this model of mobile phone. It is most suitable to use it to charge your favorite mobile phone. If the mobile phone is charged with a non original charger or universal charger, the design of the internal circuit of the charger may be different from the original charging, which will lead to changes in charging parameters such as charging voltage, which is unfavorable to the service life of the mobile phone battery.
Method / step 3:
Don't wait for the phone to turn off automatically before charging.
If so, the lithium battery will be in the situation of excessive discharge, and the internal voltage of the battery is relatively low, resulting in failure to start and charge normally. The best solution is to charge the mobile phone in time when it shows that the power is insufficient, so as to avoid excessive discharge of lithium battery and affect its service life. Lithium battery has no memory effect and can be charged at any time. There is no need to worry.
Method / step 4:
Try not to charge the phone for a long time.
When the lithium battery is fully charged, it will automatically stop charging. Even if the phone is still powered on, it will not continue to charge the battery. Although there is no danger caused by overcharging, it is unknown whether the charger can work stably for a long time. Therefore, for the sake of insurance, it is the safest to unplug the phone from the power supply after it is fully charged.
Method / step 5:
The mobile phone should be fully charged and discharged once a month or so. This is a maintenance of the lithium battery. It can effectively ensure the service life of lithium battery.
Method / step 6:
Smart phones now support some battery charging applications. It controls the battery charging process through software, which is believed to be helpful for mobile phone charging.
