Why does 'Enhanced 4G LTE services' drain my Galaxy S6's battery so fast?
I've noticed that as long as the 'Enhanced 4G LTE services' option is enabled on my Galaxy S6, the 'Cell Standby' process uses more of my battery than the screen, the operating system and all of my apps combined! I'm not even making phone calls, but it's sucking my battery dry while I'm just sitting here connected to my home wifi network.
When I disable this "feature", my battery life improves greatly, and my phone lasts all day. The same is true on my wife's phone. Also, there's no appreciable difference in my call quality or mobile data speed with it enabled.
Is this how it is supposed to work? If so, who thought this was a good idea?
