Will my older sleep scores be recalculated so everything matches the new system?

No, your past sleep data stays the same—but from February 24, 2025, all new sleep tracking will use the updated algorithm. You might see a shift in your Sleep Trends from that date, but that’s just the improved accuracy kicking in—not a change in how you’re actually sleeping.
