We report an improved measurement of D0D0 mixing and a search for CP violation in D0 decays to CP-even final states K+K- and π+π-. The measurement is based on the final Belle data sample of 976 fb-1. The results are yCP=(1.11±0.22±0.09)% and AΓ=(-0.03±0.20±0.07)%, where the first uncertainty is statistical and the second is systematic.
