title: Does going BW in low-bit mode in Android Wear actually save battery for ALL devices?
body: <p>I have an Android Wear watch face that I recently put on the Google Play store: <a href="https://play.google.com/store/apps/details?id=com.watchfuldesign.wearboy&amp;hl=en" rel="nofollow">https://play.google.com/store/apps/details?id=com.watchfuldesign.wearboy&amp;hl=en</a></p>
  
  <p>I recently got this review:</p>
  
  <blockquote>
    <p>"Please add options to add a small day of month on the gameboy screen
    as well as not going black and white since that doesn't save battery
    for everyone."</p>
  </blockquote>
  
  <p>Is that true? I had thought that by going black and white in ambient mode that it saves battery - is that not the case for particular devices?</p>
  
  <p>I read the following on Android's Developer website:</p>
  
  <blockquote>
    <p>"One reduced color space power saving method is to use a "low-bit"
    mode. In low-bit mode, the available colors are limited to black,
    white, blue, red, magenta, green, cyan, and yellow. When designing for
    low-bit ambient mode, use a black or a white background. For OLED
    screens, you must use a black background. Non-background pixels must
    be less than 10 percent of total pixels. You can use low-bit color for
    up to 5 percent of pixels on screens that support it."

  <p>I believe that seems to contradict what the reviewer said but am not sure. Does anyone know exactly which modes should go BW and which ones don't need to for saving power?</p>
  
  <p>(My watch face looks muuuuch better in color so I'd love to not make it BW in power saving mode - and it could really help my slumping sales!)</p>
  
  <p>Thanks in advance!</p>
