I recently changed the battery of my Switch 1, if for most of the process it was easy, and I really struggled on two points. 1) the plastic part into which the screws are screwed broke, and it is tough to remove them. 2) ungluing the battery with isopropyl alcohol without breaking anything was very long for me. I recently changed the USB port of my Fairphone 4 and it was just unscrewing and screwing. So for me it is a great change from Nintendo.
