Yes and no. Even when refreshing rapidly the power draw is still significantly lower than something like an LCD, but not as low obviously as when refreshing slowly. It is nice to have the option of a high refresh rate if needed occasionally, but since every eink display I’ve seen with it to date suffers from absolutely horrendous ghosting when doing so the utility is highly questionable. Lets just say I am very skeptical of that claimed 30 Hz refresh rate and highly suspect it’s impractical marketing BS.
More like 1930.
