 "title": "XIAO ESP32S3 Sense power draw: ~100 mA streaming over Wi-Fi, 2-3 mA light sleep, and the Sense board leaks 1-4 mA in deep sleep; burst duty cycle sized to a power bank's shutoff window",
 "symptom": "Choosing a sleep schedule for battery operation requires the board's per-state draw, but board-level numbers differ a lot from the bare ESP32-S3 chip specs, and the Sense expansion changes the deep-sleep picture entirely.",
