Hello @drvval
when I run M5Core2 v1.1 from battery, power consumption gets down to about 5.2 mA @ 4.2 V in ESP32 deep sleep.
BTW: Interestingly when running from battery I can turn off the boost circuit.
In my test I now only turn LCD backlight to zero and turn off boost circuit. When I turn LCD and/or TP off things start to go wrong. My guess is that ESP32 SPI / I2C bus gets confused if devices are suddenly disappearing.
Thanks
Felix
