I am using particle Boron which powers a low power microcontroller (MCU). I make Particle Boron sleep and make it wake up every 10 minutes to collect the data from MCU. When I measure the current of Particle Boron its consuming around 13mA during its sleep even though I have switched off charging. I know for sure that the low power MCU connected to boron consumes only 1-2 mA of current. Can you please let me know if there is any other reason for particle Boron to consume this much current during sleep??
