I don’t really understand what you mean but I only have bluetooth off on my 6S. Have you tried restoring the phone? Where did you get the battery from? There are many batteries out there that are bad aftermarket quality and refurbished batteries (batteries that have been repackaged and the gas gauge board being replaced meaning that these refurbished batteries are really 60-80% battery life instead of brand new 100%).
