Sudden high Bluetooth battery drain

I love my G2 which up until a few weeks ago has had incredible battery life. The phone is a D801 (tmobile) which has been running stock Lollipop (5.0.2) since I bought it. It appears that my Bluetooth has been taking up most of my battery. I don't recall it ever doing that prior to the recent battery drain. I have cleared out the Bluetooth cache and data, but it hasn't seemed to helped. I couldn't find any indication of a system update during this time. Any ideas, besides turning the bluetooth off when I don't need it?
