    On my AT&T variant of the S6, there is the option "Enhanced 4G LTE Services" option under the "Settings->Connections->Mobile Networks->Mobile Data" screen. By default, this option is turned on. The text that is display with this option says, "Turn on HD Voice and enhanced communications over the mobile networks when available". I understand what "HD Voice" is, but what about the "enhanced communications"? I tried doing a Google search for this option and looked through the online Samsung Manuals but can't find any explanation of what this option really does.

    I ask, because in a lot of the "battery drain" postings a lot of people are recommending turning off this option which will supposedly reduce the cell standby battery drain. I'm not overly concerned about the HD Voice, but I want to make sure I'm not reducing the phone capabilities for other features. Anyone know what this option does? Thanks.

    It's usually used for HD voice calling.

    I found on AT&T website the following :

    I had the same question when I got my phone. I'm still wondering though, because if I uncheck the "Enhanced 4G LTE Services" and only leave the "Standard" option checked, then at the top notification area it still says 4G LTE. So by leaving the Standard option Im still getting 4G LTE, whats the difference?

    I've turned it off as others recommended for battery life reasons and it doesn't really effect your high speed data or voice calls. You'll still receive the 4G LTE speeds and you can check the speeds yourself using the Speedtest app (with that option checked then unchecking the option). No noticeable difference in speed nor in your voice calls.

    so it will not assist at all for data LTE stuff? I've noticed much weaker LTE compared to my S4.
