Low Power Consumption for the first 10 seconds on nRF52832

Question

Hello, 
 we are developing an application with a nRF52832 on a custom board. The application works fine. The application on the nRF52832 consumes 2.2mA @ 2.5V. 
 The other components on our custom PCB and the power supply requires that we start our application on the nRF52832 with a delay of about 10 seconds. The power supply are weak zinc-air batteries. Adding capacitance is not possible in our case. 
 Otherwise the total current consumption of the PCB in the first seconds is too high. 
 This means that our nRF52832 gets power and has to stay then for about 10 seconds in a state, where it only draws a few 100 µA. We need no functionality in this first 10 seconds. 
 
 Our question: Is there a way to achieve, that our nRF52832 draws only a few 100 µA without any functionality for about 10 seconds after it gets power? 
 
 Thank you very much in advance. 
 
 Best regards, 
 Michael

Can trivially done with app_timer module (this supports both one-shot and repeating timers). 
 volatile bool run_init=false;

static void TimeoutSekunde(void * context){
 run_init=true;
}

int main() {

 app_timer_create(&initTimerID, APP_TIMER_MODE_SINGLE_SHOT,TimeoutInit);
 app_timer_start(&initTimerID, APP_TIMER_TICKS(10000),NULL);
 
 while (1) {
 if (run_init) { 
 do_run_init();
 run_init= false;
 }
 idle_state_handle();
 }
}
