Energy efficiency

Sonos claims the Move 2 is up to 40 percent more energy efficient than the original, and this review’s measurements support that improvement, helping explain its longer battery life and lower power draw in everyday use.

A dedicated Playtime Boost mode can stretch the Charge 6’s runtime beyond its standard rating by dialing back output and bass weight, and paired with its newer, more efficient Bluetooth radio this gives listeners the flexibility to prioritize either a few extra hours of endurance or fuller sound quality depending on the situation.
