  We report the recent measurements performed using the data sample collected
from 2019 to 2022 by the Belle~II experiment~\cite{Belle2:TDR} at
$\Upsilon(4S)$ resonance, corresponding to an integrated luminosity of
$362~\mathrm{fb}^{-1}$. We present the measurement of $B$ lifetime and mixing
frequency, the time dependent CP-violation analyses using the $B^0\to J\psi
K_S^0$, $B^0\to \phi K_S^0$, $B^0\to K_S^0K_S^0K_S^0$, $B^0\to K_S^0\pi^0$
decays and the implication of the latter for the isospin sum rule, the
observation of $B\to D^{(*)} K^-K_S^0$ decays, the analysis of $B\to
X_s\gamma$. We also present the measurements of the angle $\gamma$ using $B\to
DK$ decays, with the combined dataset collected by Belle and Belle II.
