The author suggests using dark gray instead of black, but then also says that when pixels are completely deactivated on OLED, it saves energy. These seem to be contradictory pieces of advice. What am I missing?
Perhaps instead the UI could just slightly bump everything from black to the darkest gray, until the scrolling has finished?

Win some, lose some.
> UIs that require efficient battery usage can use true black. In these cases, some devices (such as wearables with OLED screens) can turn off any pixels that display black to conserve battery power.
Regardless of specific hardware implementations, it can be agreed upon that patterns which can cause some non-negligible amount devices to be less energy efficient are anti-patterns.
I'm pretty sure it works a little differently, but that's the idea.
