Not clearing events is definitely something that can cause higher current consumption. However, the ADC driver should take care of this.

Hi,

can it have something to do with clearing events ?

NRF_ADC->EVENTS_END = 0;

It is definitely not an error since I can still communicate via nus (uart over ble)

the current is about 1mA, I expect it to go down to about ~100uA

Thanks

I'm pretty sure the current draw increases because you end up in the error handler when you start to remove code. In the error handler the CPU is just spinning giving a high current consumption. What is the current consumption you are seeing, and what current consumption are you trying to achieve?

Another issue, why is removing the service initialization causes the current draw to increase considerably as well ?
