  We study the problem of the stability of a two-component droplet. The
standard solution known from the literature is based on a particular form of
the mean field energy functional, in particular on distinction of hard mode and
soft mode contributions. By imposing the constraint on densities of the two
species which minimizes the hard mode energy, the problem is reduced to a
stability analysis of a one component system. As opposed to this, we address
the issue in full generality. Our analysis is valid for arbitrary forms of
energy density. We formulate constraints which correspond to the physically
relevant situation of a system which has unconstrained volume and may evaporate
particles. For the specific case of a two component Bose-Bose droplet we find
approximate analytic solutions and compare them to the standard result. We show
that the densities of both components of a stable droplet are limited to a
range depending on interaction strength, in contrast to the original unique
solution.
