High Deep sleep current on Wemos D1 mini?

I am running a 'clean' Wemos D1 mini of a single lipo cell to the 3,3V input and need as low sleep current as possible. Sleep time in the application is way more that the short 6 minutes the unit actually 'works' after a user triggered (switch) reset.

I trigger the sleep with a:
Code: Select all  //Die at 6minutes
  die = millis();
  if(die > 360000)
    {
     DBG_OUTPUT_PORT.println("going to sleep");
     delay(100);
      ESP.deepSleep(0);
}


I was under the impression the current to expect in deep sleep mode should be around 0,03mA, but I get 0,3mA.
Is there anything else I could do or was my expectations simply of by a factor of ten..?

I think the serial interface chip on the Wemos is still powered up and they typically take about 250uA

Add 25uA for the voltage regulator, or 55uA if it is the newer version.

This page has someone stating a deep sleep current of 115uA. https://forum.wemos.cc/topic/252/new-ve ... d1-mini/10

I was hoping that running them on the 3v pin directly would bypass them. My bad.
I seen some info on how to disable serial/voltage regulator on some Arduino Pro's by alterations on the board. Anyone seen info on/been doing the same thing on the D1 mini?
