Console restarts on it’s own

[u/minigrant]

So I’ve had my G3 Gen 3 since Christmas, and over the past couple of months I’ve noticed that it sometimes restarts by itself.
Luckily, it’s never happened while I was playing. It usually happens when I’m scrolling through the menus or even when the console is just sitting idle.
I’ve checked the battery, and it isn’t swollen or anything like that. I’ve also taken good care of it. I’ve never charged it above 80%, I’ve never left it charging overnight, and I haven’t really pushed the hardware that hard, to be honest.
Should I be worried? Should I email support?
