Battery life enhancement via code? #257

I know this is a long shot but hear me out:

I just stumbled upon this really nice video about the battery consumption of many eInk notetakers:

I took the values mentioned in the video and calculated the drain in mA to get rid of the battery size difference:

It turns out that the rM2 is incredibly bad in stand-by with screen on (which also aligns well with my experience) in comparison with other devices. I have no idea what part of the code the rm-hacks developers can access and are able to manipulate. But given the possibility that this is software-related, I just wanted to ask if you can keep an eye open in case you stumble upon a feature that you think might be responsible for the drainage (and is improvable of course).

I know rM developed their own screen drivers etc and know what they're doing, so probably what I am asking is impossible, but just wanted to get it out there!

Edit: Tried to get the picture right...

Wow 😲 I will keep this open as a reminder, if maybe we find something
