I wonder if there is some battery life variances caused by this? My Kindle Libra color is at 1.64v. Then you have another user all the way at 1.25v. that's 390mv which seems pretty significant since if backlight it as zero the screen power might be a decent affect? But that's quite hard to test for without units with different voltages in hand.
If anyone else comes on this, I can confirm the small 3ds buttons do not quite work right they are slightly smaller and the cut outs that keep the buttons from spinning around are not the same
