I agree,my opinion is to uninstall those apps,and if you have a root device download Greenify,is the best app ever,i think you will see the difference and if you want a cleaning tool i I suggest SD maid (both are for root devices)
Yes,you can root it with Towelroot,this method does not trip the KNOX counter, but if you have the latest update with the new kernel you must flash the old one via odin
