Nintendo Switch Battery?

I have a Nintendo Switch and if I gamble Fortnite or so in handheld mode, the battery is all within 2-3 hours. Is that normal?

So I do not have Fortnite but as I got it, it depends on the game itself. In some games it is faster empty in some not so it is normal

Yes me too

Yes, that's normal. In demanding games like Fortnite or Zelda should be about 2.5 hours in it, with simpler hours you come to about 5 hours (in very simple possibly even more).
