I got like 100 Apps installed on mine (not including stock Nokia apps) , 95% of those are from Extra Devel. My CPU usage is low as heck but my RAM usage is sky rocket from time to time and sometimes it dropped back to 130MB usage. My up time is over 3days and my CPU still pretty normal. I just format my eMMC and copied back all my files then reboot. Took a screen shot to show you. I'm even used up 22GB of my eMMC.
