The circuitry to the left of micro USB connector, J16 produces periodic load to prevent portable smartphone charger from shutting down. Suggestion for Battery Power Application Standby current consumption is important for battery-powered product. We suggest adding a 32.768 kHz crystal and 2 capacitors on host board. The 32MHz main clock won’t be active at idle state to save power.
