Print the bootloader configuration (only available on Raspberry Pi 4 models): And then, to make sure thermals aren't causing any throttling, you can run the following commands: $ vcgencmd get_throttled throttled=0x0 # will return a different value if any throttling has occurred $ vcgencmd measure_temp temp=39. I believe my idle currents are higher than expected, and if someone could post their idle currents that would be appreciated.
