How to deal with unused pins of STM32L151 low power consumption [Copy link]

I am working on a project that requires low power consumption. The chip is STM32L151C8T6. I found some posts online that say that the unused pins on the hardware can be left floating. STM32Cube can be used to automatically generate code on the software. It seems to simulate free or something. It can achieve the effect of low power consumption on the software. I don't know how to operate it. Please give me some advice. Thank you!

Configure it to the default weak pull-up mode and then leave it floating.
