Overview

• Fitbit’s updated algorithm is now live across supported wearables, capturing brief awakenings that previous software missed.
• Many users have observed slightly higher awake time and shifts in sleep stage breakdowns since the quiet rollout in late July.
• The company confirmed the behind-the-scenes change in support documentation and a community post earlier this week.
• Fitbit describes this update as the first in a series of enhancements aimed at refining sleep-tracking accuracy.
• It remains unclear which models will receive the new algorithm, and Fitbit has not yet detailed full device compatibility.
