I've had my second-hand 3DS XL Red/Black (1st red/black model. not newer model that is out) for about a year now and it was on 4.5. I bought a Gateway for it and have been playing my 3DS on and off for a year. Just this month I started playing it again. Playing for about 2 weeks now. And twice (yesterday and today) I've experienced my 3DS just shut off while playing my backup of Smash Bros 3DS. The battery was at least half-full in both occasions. It's the only game I've tried playing on my gateway since I started again so I can try another but has anyone experienced their 3DS or 3DS XL just shutting off? My emuNAND is on 9.7.0-25U (which happens to be the latest fw as of today). Also I noticed that my Gateway unit is loading the selected game longer than usual and then when starting the game I have a black screen for about 15 seconds before the game starts. I don't remember this being the case when I bought my Gateway a year ago. I have kept the Gateway inside my 3DS all this time (for a year) so i don't know if these two issues are related to my 3DS shutting off randomly.
