If the motivation is saving power this won't do much. AFAIK the display is still refreshed at about once a second. If no code is loaded the Bangle 2 runs for a really long time. I tried to record a discharge curve and lost about 20% of battery in 4 weeks before giving up. Maybe a 0 brightness setting would be more useful for very low power use.
