Oooh.. you "know what you're doing".. wtf does that even mean? Lemme guess, you have facebook and twitter not syncing, no weather/stocks syncing, brightness turned down to 20%, minimal widgets updating, rooted, running a undervolted ROM, bla bla bla.. It isnt rocket science man. Stop acting all high and mighty lol.
And the 4G radio is shown under the battery usage, its part of the Android OS....if you were on 3g constantly, it would use less than if you had 4g on and Android were utilizing a slower data connection. 4g DOES NOT USE ANY MORE BATTERY, IT IS A CATALYST THAT ALLOWS THE APPLICATIONS/ANDROID OS TO RUN FASTER AND TRANSFER DATA FASTER. This results in a larger drain of power. Think of it as a car with a 4 cylinder engine compared to a V8. Sure, the underpowered car will still get to 100mph eventually, but the V8 will get there quicker, while using more fuel.
Like I said previously, because of ignorance of users, applications that advertise 'battery saving' are more worth while to others than those of us that know what the hell we are doing. For me, the app has no value.
Thanks for playing.
