  Consider the focusing inhomogeneous nonlinear Schr\"odinger equation in
$H^1(\mathbb{R}^N)$, $$iu_t + \Delta u + |x|^{-b}|u|^{p-1}u=0,$$ when $b > 0$
and $N \geq 3$ in the intercritical case $0 < s_c <1$. In previous works, the
second author, as well as Farah, Guzm\'an and Murphy, applied the
concentration-compactness approach to prove scattering below the mass-energy
threshold for radial and non-radial data. Recently, the first author adapted
the Dodson-Murphy approach for radial data, followed by Murphy, who proved
scattering for non-radial solutions in the 3d cubic case, for $b<1/2$. This
work generalizes the recent result of Murphy, allowing a broader range of
values for the parameters $p$ and $b$, as well as allowing any dimension $N
\geq 3$. It also gives a simpler proof for scattering nonradial, avoiding the
Kenig-Merle road map. We exploit the decay of the nonlinearity, which, together
with Virial-Morawetz-type estimates, allows us to drop the radial assumption.
