Energy saving

  • M5Stick-C has a battery of 80 mah, but in the off state lasts a maximum of 2.5 days, after which it does not turn on.
    Is it possible to put the entire periphery into sleep mode when the M5Stick-C is turned off, or turn it off altogether?
    According to my calculations, hibernation of all modules should give a duration of 30 days, and a complete shutdown - years.
    Can you update the firmware and increase the runtime?

  • Out of curiosity, how have you worked this out?
