Detailed Description

Power state control in response to battery state changes.

Enters low power mode below the board's low power threshold while discharging, and standby when the battery stays critical (0 % and not charging) for 30 s, or 2 s right after boot. Neither happens while plugged in, nor on QEMU outside recovery firmware.
