I've got the original type of 3DS both small and XL and I find XL battery life better for both 3DS and DS games. There isn't a lot in it though and my first gen Vita is about the same compared to 3DS mode battery runtime. Vita seems to last a long time when used for remote play but not sure how much longer but it gets to the point where you seem to forget about the battery which I guess is a good indicator.
