How to charge the mobile phone correctly
1, charge when you have the chance.
Most people are used to charging their mobile phones when there is no electricity, thinking that this can make the batteries more "durable". Actually, it's not, but it will cause greater battery loss.
Charge a little at a time, even if it's only for 5 minutes or 10 minutes. The damage to the battery by using sporadic charging is very low. Don't wait until the battery is completely exhausted before charging your mobile phone. If the battery is hungry for a long time, it will cause greater loss to the battery.
2. The power should be kept at 65%-75%.
According to experts' opinions, the proportion of lithium batteries in smart phones remains between 65% and 75%, and the service life of batteries is preliminary. In daily life, it is necessary to develop the habit of charging at any time in order to keep the battery power within this range.
3. When the power is close to 20%, the battery will be charged.
According to the expert's point of view, the battery is in a "virtual" state when the power is less than 20%, which wastes the battery life, so it is necessary to start charging when the power is about 20%, which can keep the battery healthy for a long time.
