Battery issue on Aviator Gen2

Hi all,

I finally found what is draining battery overnight on Aviators. There is option in Connections, wifi, use wifi for aviation weather, when it is on, and you disconnect bluetooth, for ex. if you leave watches in bathroom and go to bed off bluetooth range, watches connect to wifi, because weather download, and it is connected all the time on wifi, this drains whole battery over single night. I cant understand why it keeps connected and does not disconnect after weather download...
