As you have guessed, more potential difference across the plates means less voltage around the loop, hence less current (for a given circuit resistance). In theory this process is infinite (I''ll avoid the math here), i.e. that equilibrium is reached after an infinite time. Actually after 3-5 time constants you may consider the capacitor charged.
