After Dfu current problem

[SametK]

There are 2 software: 1.0.1 and 1.0.2. When I load the 1.0.1 hex with bootloader with the programmer, it draws 9uA current. But when I update it to 1.0.2 with DFU, the current increases to 360 uA, there is a strange situation. When I load 1.0.2 from segger with just the programmer, the current is normal again, but when I do DFU, I get an error....

Experiencing increased current consumption after a Device Firmware Update (DFU) can be challenging. Ensure that the DFU process doesn't inadvertently enable peripherals or leave the device in a higher power state. Review your power management settings and confirm that the application enters the expected low-power mode post-DFU. If the issue persists, consider exploring alternative microcontrollers like the MIMXRT1052CVL5B, which features an Arm Cortex-M7 core running at up to 600 MHz, delivering high processing power for real-time applications. This MCU offers advanced power management features that could better suit your application's requirements.

Hi Samet, 

Could you give more information about your application  ? Are you using nRF5 SDK or nRF Connect SDK ? 

Did you do any modification between v1.0.1 and v1.0.2 or they are identical ? 

Is there any chance that the bootloader actually draw some current ? 
In your graph, what's the interval between the peaks ?
