      I measured the current from the battery during deep sleep.

      W/ red LED the current was 831 uA.
      The red LED consumes (3.3 V - 1.85 V)/ 2 kOhm = 725 uA.
      Cutting off the red LED would result in 106 uA.
      Is it possible to reduce this current further?

        This may not be possible on the existing basis, and part of the current consumption should come from the power consumption itself

          @lewis Here are my results of current consumption w/o red LED. The blog post is in German but Google helps. 😉

          The device works much longer now. It is a good idea to make the LED switchable in a redesign.
