Light-Sleep：Applications for cpus, such as Wi-Fi switches.When maintaining a Wi-Fi connection, if there is no data transfer, you can turn off the Wi-Fi Modem circuit and stop the CPU to save power according to the 802.11 standard (such as U-APSD).For example, at DTIM3, a sleep 300ms is maintained, and a Beacon packet that wakes up to receive an AP from every 3ms is about 0.9 mA. Deep-Sleep：Applied to does not need to always keep a Wi-Fi connection scenario,the application of a long time to send a packet(e.g.,every 100 seconds measure time temperature sensor),per 300s we wake up to 0.1s-1s connected to the AP,the overall average current can be far less than 1mA.
