I have JuiceDefender installed and running, and I wonder how this works when my GS3's "Power saving" mode is active. It seems their functionality is mutually exclusive, with JD turning off the antenna when the screen is off, and the default Power saver just limiting CPU performance and whatnot. Has anyone tried this combination? Did they notice a difference when using one and/or the other? Also, is it worth buying the paid versions of Juice Defender, and if so, should I go for Ultimate or stick with Plus?
