So ULP amps goes from ~0.2mA first cycle to ~2mA on subsequents? Wow, that's an order of magnitude! Are you cloud syncing via wifi? What happens if you temporarily comment out the wlan section, are the subsequent ULP cycles still high current?

I got a Lolin D32 preloaded with micropython & the battery voltage presented to gpio35 via a voltage divider with 1% 100k resitors. The battery is sitting @ 4138mv but the value I get from gpio35 can vary from 4080mv to 4196mv. I've struck this variation with the 12 bit adc on other esp32 based boar...
