NRF54L15-DK sleep current problem

[secondbest]

Hello Nordic team,

I bought newly announced NRF54L15-DK board. Its version is v0.9.1. I am using NCS v2.8.0. I tried to test sleep current via nrf52840-dk and nrf54l15-dk. When I compile my sleep_test project for nrf52840-dk, I am getting following result with 3V supply voltage.

The result seems okay to me for nrf52840-dk. However, if I use 3V supply voltage for nrf54l15-dk, I am getting following strange sleep average current.

After that, I tried to use 2.5V supply voltage with nrf54l15-dk and I got following idle current results. Strangely, I am seeing current spikes at every 4 seconds. 

I watched Nordic's demo on YouTube and I feel there is no this type of ticks on this demo. I wanna learn that how can I use 3V supply voltage and How can I solve this sleep issue?

Thanks.

 Simonr Could you share your source code for "nrf54l15_xxaa_application.hex", please? I can't get nRF54L15 to go below 120uA current consumption using sys_poweroff but with you hex it drops down to 0.8uA  Not sure what I'm doing wrong...

Hi Simonr , 

having a similar problem as pawpec  with a sleep current of ~5μA, 
I wanted to ask if it is possible for you to share your minimal example?
