I'm having the same issue of the phone powering down with plenty of battery remaining. Upon completion of the shut down the phone displays a completely empty battery icon. When I attach a charger the battery icon reappears on the screen (today showing 66%). This is simply unacceptable! It started at about 35% and has now begun to do it with 60+% remaining. I don't have it loaded with apps and photos and I uninstalled any new apps. From my research this seems to be a common problem with the Droid Turbo. I've done the "Health Check", I've watched video's until it drains to 15% then let it shut down and charged it with the power off hoping to reset the battery monitor. Nothing works. What's the fix? I can't buy a new phone every 2 years. I use the Turbo charger and the cordless charger that goes with this phone. Hasn't been dropped, no liquid and no physical damage. The touch screen is responsive!!
