PS4 stuttering/dropping slight FPS

So last week in PS store, my ps4 froze, since then I rebuilded database and cleaned stuff up like notifications. Played a couple of hours and saw it was dropping slight fps ever so often and kinda stuttering a bit, hasn’t frozen since the 1 time. Searched on the internet about such issue, but they all say it keeps freezing, while mine doesn’t, they all say it’s HDD related, but with mine not freezing I’m not sure if mine is HDD related, anyone got some help/tips please? Thanks in advance
