Gear S3 discharges quickly when connected to Galaxy S6 used as a Hot Spot

[DWH101]

On a recent road trip I turned on the Hot Spot in my Galaxy S6 so my daughter could watch Netflix on her iPad. About 4 hours into the trip my Gear S3 gave a warning that it should be set for Power Saving and an hour later it was totally dead. What's up?

Perhaps the watch was trying to pull in the wifi signal. I keep wifi disabled on my watch, but your situation is similar to what happens to me occasionally with the cellular radio. It's set to always on, and I usually can get through a whole day. But if I'm in a building or area with a weak signal, I can drain my battery in a handful of hours, just like you experienced. Assuming you had the cellular radio disabled, why that would happen to you within the confined space of a car, I dunno...

I leave WFi and Cell turned on at all times. When I'm home reception bounces back and forth and the S3 never drains unusually fast. It's probably a good idea to follow your suggestion and turn off the wifi when I'm using my phone as a hot spot.
