TFTs have a backlight that produces all the colours brightly and the panel blocks the parts that are not needed in the image. An OLED display just produces what's needed to make up the image. So that should be more efficient. Plus, maybe your Lite had enough charging cycles already to make a bit of a difference. ?Ditnt measure the time, but could it be the batteries on the Oled are much better than on the Lite?
People are saying there will be a 4K Switch since years now.Oh man, people are still saying a 4K Switch is coming, and even worse, they're saying it might not be backwards compatible with Switch, because each Switch game contains its own version of the Switch GPU drivers, and they would have to be patched on a game by game basis for a new GPU.
They say developers are currently being told to target late 2022, but that it might not release until 2023.
