Particle Boron Consuming more current in sleep mode


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??

This problem got solved. Had to use delay between and System.sleep()
