If you hate that, just open all the apps and stuf you have on your phone then close everything (long press on open apps, close all) then it will go down and it'll stay there until first reboot.

The memory is the cache.

Linux memory consumption concept
Linux memory consumption concept is all about efficiency. The system’s RAM is a resource that is meant to be used; 100% of it (if possible), all the time (if possible).
Linux utilizes unused RAM to cache data and filesystem meta-data from slower storage devices (Flash or disk) because fetching the information from the RAM is much quicker: There are no bottlenecks such as slow physical media, slow buses or device clocks, and not decompression is required.
Assuming there are no memory leaks, the reason that memory report tools report low amount of free memory is because the RAM is considered to be wasted if it isn’t used. This concept may require some time to digest, because conventional thinking may lead to the conclusion that an efficient system is a system with a lot of free memory. This is not entirely correct. In Linux case, the kernel tries to utilize the most of the RAM to improve the system performance. Keeping the cache means that if the kernel or a task needs the same data again, there’s a good chance it will still be in the fast cache in memory.

I got no apps open everything is closed well apart resource monitor and the screenshot app.
Surely i should have more free memory?
