I have always kept my Nexus 5's Bluetooth on all the time, since I'm frequently in and out of the car and I otherwise wouldn't remember to turn it on and off each time. I have never had trouble with battery life, generally going 24 to 26 hours between charges.

The last two days, I have suddenly seen big drops in battery overnight and the #1 user is Bluetooth at 8%. In the year I've had this phone, Bluetooth has never even shown up on the battery usage display.

I haven't installed any new apps that use it, although some previously installed apps have been updated. I've rebooted the phone and just did a partition clear from recovery mode. Other ideas?
