1. Check what applications are running and disable those you don't need or uninstall those not needed or used (The list of apps running also show the amount of RAM used). Reboot and check RAM used. 2. Using Bluetooth as an alternative to USB install Cyanogenmod 11, you will be rooting your OS which will later give you more control over the processes running.
