Watchface background color effect on battery

"since the power glass receives the sunlight prior to the display" aha, this is crucial.
Ok, I'll run a few tests & report back. Thanks!

Hi, 

You dont have amoled screen, so no matter which color you put, it will drain the same. 

Um, I don’t get your point. There’s the red circle spaced out from the display to get better translucency for the solar panel — why would anyone do this, if the solar panel was invisibly placed in front of the display? Thus the solar panel has to be placed behind the display wich means that the display must affect the translucency, otherwise they hadn’t spared out the red ring.

There are two different solar collecting mechanisms on the Fenix 6. The red ring is the "high density" photovoltaic cells. The rest of the screen is covered with "power glass" that sits between the screen and the surface glass. This is almost transparent so it collects little sun (but at least it collects some). If it were behind the display it could collect no sun at all.

Here's an image I found which shows pretty clearly what @LoganWest described:

The High Density (100%) ring surrounds the Low Density (10%) solar cell - both are positioned above the display and behind the crystal.

So theoretically, a white watchface should charge slightly better, because white will reflect more sunlight, and reflected light will pass through the power glass a second time. But i doubt that it will make any noticable difference. 

A solar cell is only active on one side, so - even if only miniscule benefit claimed by you - there would be no directly reflected light energy back to the front surface of the solar cell in the watch.

White background or black background, I suspect one would be hard pressed to prove any difference in energy consumption - under any use circumstances.
