@maxstack - Yes, I used ESP DeepSleep set to wake on Button A being pressed, but I would say that the 5 hour time was not under ideal conditions, as I occasionally woke up the device to confirm it was still working and to check the time - a resonable activity for a watch.

No matter what value i use for ScreenBreath, the backlight remins on and flattens the M5StickC battery within ~5 hours. I wish to use my M5StickC as a watch and I need a much longer battery life. Can someone help me understand how to turn the display completely off?

@vvs551 I too have noticed similar low charge rates occasionally on my device as you have captured in the second of your pictures. I believe the M5StickC limits it's charge current when the temperature is excessive. I can see in the bottom picture your device is reporting a temperature of 61.3Deg C.
