about current consumption at 1.8V

[Qinghua]

Hi, Schematic and Code As shown above, VCC 3V (DEC2 and VCC open) current is only 3.8uA, but VCC 1.8V (DEC2 and VCC short circuit) current exceeds 1mA, what am I mistaken? Would like to hear any suggestions about Low voltage mode, thank you!

OK. So this question has nothing to do with ble_app_uart in particular

This seems to be question about current consumption at 1.8V vs 3.3V ?

I think you need to update your question title to reflect the actual question
