As long as the WLAN on the chip works, power is consumed. When working without a constant connection to electricity, it is important to reduce the current consumption of the device. However, to save power and maintain acceptable performance, there must be a power-saving mechanism.
When the STA enters power-save mode, the WLAN on the chip goes into sleep mode (extreme low-power (ELP) mode), drastically decreasing power usage.
