Nowadays, the demand for mobile phones is increasing, and they are indispensable for leisure, office, and daily communication. Therefore, the battery life of mobile phones has become particularly important. The warning sound of low battery is particularly harsh, and I believe many friends have this question: why should we remind them to charge when the battery reaches 20%? Today, let‘s explore with everyone.

The 20% battery level reminder is similar to a self-protection mechanism of a battery, telling you to charge the battery in a timely manner, which can effectively extend its service life.

If the battery level is below 20% and continues to be used, it may cause a decrease in the chemical activity of the battery and shorten its service life.

If the phone‘s battery level is below 10% or 5% and you continue to use it, it may cause excessive discharge of the battery, low internal voltage of the battery, and result in the phone being unable to turn on or charge.
