High RAM usage

Ever since i bought the phone (mx 3 64 GB) I experienced a high RAM usage …
The flyme version is currently 4.0.5 and most of the time i have only 70% ram left (when the phone is unused- around 300-500 MB free ) according to Clean Master while my friend that own Nexus 4 have most of the time 50% free.
This problem was even at 3.5 version and my friend and i having pretty much the same apps…
Is there any good way to solve it ? and any one else experiencing that problem?

By the way there is a process or something called MzAccount that take around 100 MB

Hmm, if you have 70% left and your friend only has 50%, it means yours is better… :D
