Performance, CPU temp, and battery life on Linux

This utility is a bit new to me, this screenshot of the powertop output for my machine (Linux Mint 20.2, upgraded to 5.11 kernel, installed tlp without any additional tuning) seems to show a fully idle power draw of the mid-3s watts - is that a somewhat normal number? Seems reasonable that the display backlight is the dominant component, not sure if the draw from bluetooth is expected (no bluetooth devices connected)
