There is always a concern about keeping the battery charged in a smartphone. Because we do many things from online payment to daily use with the smartphone. In such a situation, to make the phone's battery last for years, it is very important to keep it properly and charge it.

To charge the phone, the ratio of 20-80 should be kept in mind. That is, you have to charge the phone up to 80 percent and charge it before the battery gets 20 percent. Keep in mind that the phone's battery should not be allowed to discharge completely.

Let us tell you that lithium-ion batteries work better when they are 30 to 50 percent charged. On the other hand, charging it 100 percent puts extra pressure on it and the battery can even get damaged. Note that the phone should always be charged with the original charger. This keeps the battery life good.
