Problems that occur in system on mode

Question

Hi，the Nordic team 
 I use the SED device by system on mode.I found that my static average power consumption increased by more than 20 ua after I defined an IO port to use and interrupt wake-up. The lowest power consumption did not go to a few ua, and the lowest power consumption was 20 ua. 
 this is my code: 
 // init GPIO and Interrupt
void report_gpio_init(void)
{
 if (!device_is_ready(report_gpio.port)) {
 LOG_ERR("GPIO port not ready");
 return;
 }

 gpio_pin_configure_dt(&report_gpio, GPIO_INPUT);
 gpio_pin_interrupt_configure_dt(&report_gpio, GPIO_INT_EDGE_BOTH);

 gpio_init_callback(&report_gpio_cb, report_gpio_callback, BIT(report_gpio.pin));
 gpio_add_callback(report_gpio.port, &report_gpio_cb);

 LOG_INF("Report GPIO initialized");
}


static void report_gpio_callback(const struct device *dev, struct gpio_callback *cb, uint32_t pins)
{
 LOG_INF("GPIO triggered, sending status");

 // 提交工作队列进行上报
 k_work_submit_to_queue(&coap_server_workq, &report_status_work);

}

 k_work_init(&report_status_work, gpio_status_report);
 
 void gpio_status_report(struct k_work *item)
{
	ARG_UNUSED(item);
	// 读取引脚电平
 bool pin_state = gpio_pin_get_dt(&report_gpio);
 LOG_INF("Sending GPIO status via CoAP: %d", pin_state);

 uint8_t payload = pin_state ? 1 : 0;
 coap_send_request(COAP_METHOD_POST,
 (const struct sockaddr *)&provisioning_client_addr,
 status_option, &payload, sizeof(payload), NULL);
}
