Last night, I was watching a 40 minute video on my Droid Turbo using a Google Cardboard. I have my Turbo in a cheap clear plastic case I got off of Amazon. The Turbo was getting hot as it usually does when I watch a video with Google Cardboard. Then, in the middle of the video, the phone shut down. I suspect, it was because the battery died. I took the Turbo out of my Cardboard and plugged it in. A green LED, to the left of the front facing camera turned on. The phone would not boot. I left it plugged in all night. Woke up this morning to find the LED off. I tried to boot the phone to find that it would not. I tried aeveral more times with no luck. I unplugged it, plugged it back in and the green LED lit up again, but it still would not boot. I left it alone for a few minutes and finally it booted by itself. When it finished booting, the battery indicator was at 4%. So, it had been plugged in all night but was not charging.
is there an official explanation of what the green LED means? I tried googling for an answer but found none specific to the Droid Turbo. My guess is that it's some sort of emergency indicator. I hope I did not damage my Turbo somehow.
