We investigate cumulative burst occurrence trends of five soft gamma repeaters (SGRs) and introduce an indicative mea‐sure for the duration of their outburst phases. We find a clear distinction between the durations of the active episodes of persistent and transient magnetars: The outburst episodes of the persistent sources are significantly longer (≲100 days) than those of transient sources (≲10 days). We also investigate burst‐induced changes in the radiative behavior of transient sources and suggest a mechanism for the constant flux trend seen in the early phases of the outburst of SGRs with low burst rates.
