Abstract	This paper summarizes the first results on $B^0$ lifetime and mixing from early phase 3 Belle II data corresponding to an integrated luminosity of $\int \mathit{\text{L}}=2.7f{b}^{-1}$. It presents two analysis that demonstrate vertexing and tagging capabilities useful for furhter time-dependent CP violation measurments. The first analysis uses partially reconstructed $B^0\to D^{\ast +}l\nu$ decays combined with an additional high momentum lepton in the rest of the event. The latter one uses fully reconstructed hadronic decay final states $B^0\to D^{(\ast )\mp }{X}^{\pm }$
