"Turning the GPS on" in the Settings is not doing anything to the battery. It just *allows* applications to use the GPS. You can have this setting turned on, use only Gmail and Browser and you will never seen the battery drain faster than with the setting off. That's also why there's very little reason to have apps turn it on/off: it's a *PRIVACY* feature. Do I want apps to be able to change my privacy settings behind my back? No.
Applications draining the battery are poorly written applications that do not stop requesting GPS updates even when they are not in the foreground, etc. We've also seen cases of applications forcing WiFi to be on (and that definitely drains the battery.)
