Sumario:Expected b-tagging performance in ATLAS during LHC Run-2 is presented together with results of commissioning studies with early Run-2 data. The performance of b-tagging is expected to be significantly improved in Run-2 thanks to the addition of a new pixel detector layer and to updates in the tracking and b-tagging algorithms. First commissioning studies show a promising agreement of Monte Carlo simulation with the new 2015 data recorded at 13 TeV.
