The numbers below apply to the BCM43362 Wi-Fi chip.Other Broadcom Wi-Fi chips may consume less current and/or have other power consumption modes.From the 43362 datasheet, the average current consumption for DTIM=1 is 1.9mA.200uA of this is quiescent sleep current, 1.7mA is current used to wakeup to receive a 1ms beacon every 100ms.If the listen interval is set so that the 43362 only wakes every 10 (or 100) beacons (instead of every beacon),
- 1 second wakeup : 200uA = sleep, wakeup is averaged at 170uA
- 10 second wakeup : 200uA = sleep, wakeup is averaged at 17uA
