A new report suggests that Nintendo consider using a new mini-LED display in the unit to improve the basic display of the original and also extend the battery life of the hybrid system, as they are much lower than standard LCD screens
Another company that reportedly went down this route is Apple, which is known for its premium but expensive product.
As usual this is just a rumor and it should be noted that Nintendo did not mention the most powerful revised unit of Change that will be released in 2021.
