  In this work, we revisit a toy model proposed by Camanho {\it et.al.} [JHEP
10 (2015) 179] and extensively study the possible existence of gravitational
phase transition from AdS to dS geometries by adding the Maxwell field as an
impurity substitution. We show that the phase transitions proceed via the
bubble nucleation of spherical thin-shells described by different branches of
the solution which host a black hole in the interior. In order to demonstrate
the existence of the phase transition, we examine how the free energy and
temperature depend on the higher-order gravity coupling $(\lambda)$ indicating
the possibility of thermalon mediated phase transition. We observe that the
phase transitions of the charged case is possible in which the required
(maximum) temperature is lower than that of the neutral case. Interestingly, we
also discover that the critical temperature and the coupling $\lambda$ of the
phase transitions are modified when having the charge. In addition, our results
agree with the claim that the generalized gravitational phase transition is a
generic behavior of the higher-order gravity theories even the matter field is
added.
