I have used iStat Menus for a couple of hours and it made a sizable dent on my battery life, so I uninstalled it right away. macOS is a bit sensitive about being woken up constantly. Maybe it won’t be a problem on a desktop machine, but running these on Mac laptops is not free. Note that iStat Menus have its own set of daemons it uses for keeping tabs on system usage. It doesn’t just hook to the kernel via interfaces and display stats.
