Passport gradually slowing down

When I first purchased my passport was lightning fast. It is still very quick but I have noticed an overall slowdown relatively speaking. Is there some sort of cache/memory clearing that needs to be done? On my old 9900 "Alt LG LG" would make a significant improvement. I have latest 10.3 installed according to Rogers

I never experienced any change in performance in terms of speed in my previously owned 2 Z10 phones nor my Z30. They're the same fast as their first day.

Maybe you have filled storage with apps?
