Improved Battery Life
If Nintendo decides to stick with a hybrid portable/home console model for their next Nintendo Switch system, improved battery life is an absolute must-have. Both the minor Switch revision and the Switch Lite have improved battery life, so it isn’t too much to expect the next system to be even better.
Of course, the exact battery life duration can be drastically different depending on the particular game, screen brightness, and other factors. But overall, it would be nice to have something that lasts longer than what is available now. Ideally, that would mean expecting five or six hours at minimum.
This will keep fans playing for longer amounts of time while in handheld mode before needing to charge again, which is essential for an on-the-go console.
