It is a complete oxymoron one cannot see it and have to guess the % by looking at the battery every single place where battery is show should have both % and range! Who would think otherwise just place the % inside the battery icon and done. No more space consumed. When looking at the energy screen wow there is so much white space you would think there can be 20 pieces of other information there. 

Putting the percentage energy inside the battery icon and the range in the normal place requires no additional screen real estate. "Both" can be a third option, keeping "range" and "energy" for those who don't want to see both.
