Electron and Photon performance using data collected by CMS at $\sqrt{s}$ = 13 TeV and 25ns

This note describes preliminary performances of the electron and photon reconstruction with the CMS experiment using data collected at $\sqrt{s} = 13~\mathrm{TeV}$ and with a LHC bunch spacing of 25ns. Electron and photon key discriminating variables and their data to simulation agreement are shown. The identification and reconstruction efficiencies are also computed and compared to the ones from the simulation. Performances and data to simulation agreement are expected to improve with future calibrations and reprocessing.
