The fidelity of light with arbitrary polarizations stored in a warm <sup>87</sup>Rb atomic vapor at different storage time is studied. The exponential decay of regeneration efficiency with the storage time is observed and a detectable signal at 300-¹s storage time is still existed. The storage fidelity at different storage time is well maintained in our experiment.
