This actually has little significance. If we take the same Japanese market, which is 100% the most important for Nintendo, one of the reasons why so many Switches are sold is not only because it is portable, but also because this console holds its charge surprisingly well. The OLED version, depending on the game and screen + volume settings, usually lasts about 2-6 hours, and one of the reasons why the Switch Lite sells so well in Japan is because it holds its charge even better, on average +1 hour (3-7 hours But you pay for the best charge by not having a TV connection). That's why Nintendo will 100% aim for about the same figures, if they make a console that will be like the PS4 PRO in a portable form but will hold its charge for only 1 hour, I'm afraid the Japanese won't appreciate such a product.
