I was able to get ahold of Samsung technical people and here is what they had to say.
1. Turn in your old Note 7 and get a new one as soon as possible.
2. Some additional comments:
a. Turn off fast charging.
b. Turn off phone at night.
c. I asked about a battery widget to monitor battery temperature, they had no problem with this but would not tell me the temperature that the battery would become dangerous.
Note 7 (just in case, hog = Harley Davidson)
