[Nissan]'s latest concept is called Signal Shield, and it relies on a 180-year-old creation -- the Faraday cage. A Faraday cage uses conductive material to block electromagnetic fields. Installed in a Nissan Juke's center console, it's capable of blocking all communications to the phone, whether it's Bluetooth, Wi-Fi or regular ol' phone signals.
Thanks to its conductive properties, a Faraday cage blocks electromagnetic signals, preventing them from leaving or entering the cage.
Obviously, the goal is to prevent distracted driving. And it succeeds to that end, because a phone that can't do anything isn't going to distract a driver. Owners will still be able to use the phone through the infotainment system, thanks to a wired connection inside the center console.
[...] Or you could just head over to Amazon and buy a Faraday cage for less than $10 and keep it in your glovebox. That's always an option, too, even though it's far less elegant.

Hmm, that's weird. I have a Galaxy S5 and I leave BT and Wifi on all the time, and I get excellent battery life. I could probably go 2 days if I kept the screen off most of the time instead of playing games. However, I will say my battery life is significantly better than it used to be, after I went through all my apps and disabled all the crapware/bloatware apps that come pre-loaded.

I wish there was a way to stop scanning for Wi-Fi once I was logged in to a node, but it continually scans and updates the list every couple of seconds. What version of Android are you using on your S5 ? The BT I find is the biggest user of power so I keep it off unless I get in the car for a long drive. If it just back and forth to the market I just ignore the thing until I get stopped.

I'm on Android 6.0.1. I've been in a location without radio access now for almost 7 hours (with a few breaks where I could reach the tower), with both WiFi and BT on, and I'm down to 83%, and that includes using the phone (for a simple game) during those breaks).
I just checked the advanced options for WiFi and I even have "keep Wi-Fi on during sleep" enabled.
For Bluetooth, there's an option to make your phone visible to other devices (besides just devices you're already paired to). It's unchecked on mine; I'd recommend making sure this is off for you too.
I also checked my "Power Saving" settings and both "Power saving mode" and "Ultra power saving mode" are disabled.
