@oliv I've been trying to solve this again and I've found something very interesting in my project:
Using the sleep.ino in the examples in Arduino IDE with M5StickC library installed I've confirmed this:
When the device goes into light sleep it draws 6mA
when it goes into deepsleep it draws 2mA
however if I press the power button just once, in deepsleep it draws 25mA for that loop of the program, once you press button A again the current consumption returns to 2mA in deepsleep.
However, when I run the program for using my M5StickC as a smart watch, when in deepsleep it draws 2mA in deepsleep like normal UNTIL I press the power button just once. If I do that, it draws 16mA in deepsleep! The only way to stop it doing this is to press the power button for 6 seconds to turn it off, and then press the power button once more. If I do that, it goes back to drawing 2mA in sleep once again.
Do you have any idea what's causing this?
