Hi Bruce. I'm surprised to hear GliderLink is consuming a lot of power. It consumes very little power on the four phones I have run it on. It's often difficult to tell how much any one app is using. Just looking at how much the battery went down while you were using the app is not necessarily a good way to tell. It could be any app on the system using up the battery. Some apps will freak out when there's no Internet connection (airplane mode) and constantly try to connect, using up the battery. On most Samsung phones, you can go into the settings to the battery page and it should show how much individual apps are using. Let me know what it says.
