      The M5stack is interesting but many details and specs are missing. Perhaps the makers can help:

      1. what is the power consumption when OFF ? Does pressing the power switch twice actually shut the device OFF -> power is zero ?
      2. what the power consumption in deep_sleep ? I get variable amount from 17 to 40mA using a USB power meter with no battery.
      3. Is is possible to measure battery voltage ?

      The M5stack is a battery powered device but very little support exists for conserving battery power, saving power, and estimating remaining battery life.

        I'm getting
        0.29a switched off.
        0.39a running factory test.
        Using a USB power meter.

        to measure battery you need a test meter
        Can't measure this tonight as cant find small allen wrench.

            I haven't had the budget to buy anymore items to test but I'm just using a cheap inline usb power meter.

                MKII (PSRAM) camera
                Standby = 0.1A
                connected = 0.14A 00592mah
                5.18V
                Running a lot cooler then the MKI

                I don't have anything else to test so that's all I can give.
