Please post apps that you find are very resource hungry and I'll add them to the main post. These are fairly resource heavy, fine if you have plenty of ram but if your running 1gb or less - it may be worth keeping an eye on them.. 1) Facebook - always fairly excessive whether cached or currently running. New version was using 148mb of my memory earlier, when you consider that is 20% of my entire usuage it is very excessive. Seriously I'm tempted to simply not use Facebook app on Android. 2) Instagram 3) yahoo weather + widget.
