Galaxy Tab A's Bluetooth draining battery when Bluetooth isn't on

My Samsung Galaxy Tab A just upgraded to Android 7.1. My battery life decreased dramatically after the update. What used to give me days of battery life now only lasts me hours. I checked my battery stats, and this is what I found: Bluetooth was using most of my battery, but Bluetooth isn't even enabled! What is causing this immense drain of battery from a feature that hasn't been enabled?
