20% battery or less

Low battery power on your phone can automatically turn on battery saving mode, or when the low battery alert appears, you will have to turn battery saving mode on manually.

low on battery

When the battery level of your phone, tablet, computer or any battery-operated electronic toy or game is lower than it should be. In some electronic toys, low battery power can cause the sounds on the sound chip to decrease in speed and pitch, which is a sign that the battery needs to be replaced as soon as possible, preferably before it drains completely or even starts to leak.
