  We study the phenomenological implications stemming from the dependence of
the tidal charge on the brane thickness $L$ for the evaporation and decay of
microscopic black holes. In general, the larger $L$, the longer are the black
hole life-times and the greater their maximum mass for those cases in which the
black hole can grow. In particular, we again find that tidal-charged black
holes might live long enough to escape the detectors and even the gravitational
field of the Earth, thus resulting in large amounts of missing energy. However,
under no circumstances could TeV-scale black holes grow enough to enter the
regime of Bondi accretion.
