Quoting just one of the smallest one feels a bit... charged. There's small tradeoffs among all of them when you account for weight.

For everyone else here's the full list:

Switch 2 Battery capacity: 5172mAh, approximately 1% smaller than current version (5220mAh) Weight: Approximately 411g, around 10g heavier than current version With Joy-Con 2 controllers attached: Approximately 548g, around 14g heavier than current version (approximately 534g).

JoyCon 2: Battery capacity: No change. Weight: each 2g heavier

Switch 2 Pro Controller: Battery capacity: 897mAh, approximately 16% smaller than current version (1070mAh). Weight: Approximately 228g, around 7g lighter than current version (approximately 235g).

N64 Controller: Battery capacity: No change. Weight: Approximately 234g, around 1g heavier than current version (approximately 233g)

GameCube controller: Battery capacity: 525mAh, approximately 5% larger than current version (500mAh). Weight: 215g, around 5g heavier than current version (210g).

They quoted what matters the most as it's for a device which has single shortest runtime on a battery: the Switch console itself.

Because who cares if the controller lasts 27 or 30 days? (Or so, don't quite me on exact numbers).
