So the Xbox Series X may be the heaviest Xbox console ever while the Series S may be the lightest Xbox console ever. Crazy.
Series X: 9.8 lb (~ 4.44 kg)
OG Xbox: 8.5 lb (3.86 kg)
Xbox One X: 8.4 lb (3.8 kg)
2005 Xbox 360: 7.7 lb (3.5 kg) (external power brick)
2013 Xbox One: 7.1 lb (3.2 kg) (external power brick) Xbox 360S: 6.4 lb (2.9 kg) (external power brick)
Xbox One S: 6.4 lb (2.9 kg)
Xbox 360E: 6.3 lb (2.9 kg) (external power brick)
Xbox One S all-digital: 5.4 lbs. (2.45kg)
Series S: 4.25 lb (~1.92 kg)
Obviously weight doesn’t matter to us compared to dimensions as it’s not portable devices (companies may be more interested however as big and heavy packages can increase shipping costs) but the difference (outside of the disc drive) is still a crazy achievement from the engineering team as both consoles will run the same games.
Series S is ~40% of the size and ~43% of the weight of the XSX.
