Hello. I have a problem, I wanted to test the power saving mode on a board with a microcontroller stm32h743vit6. For this, I made a minimal project. Where I switch to stop mode and wake up by pressing the button. Consumption in this mode is about 4.5 mA, which is a lot. I tried to switch to standby mode, and the consumption was 1.5 mA. How else can I reduce consumption??? The board is powered by a battery, all other components are removed from it.

Hello,

Try to inspire from the low power examples provided in the H7 Cube here.

Not sure what do you mean by other components are removed but double check if you have something else consuming on the board.
