Leave Bluetooth off all day. Then at night before bed or whatever, go to settings, and then battery. You will see Bluetooth has used like 3 or 4 percent of your battery. And it was never on! At least this has happened to me, every day since 4.4 update. Other people have chimed in on this too.
I checked mine earlier before charging it and it didn't have any bluetooth usage showing. I did reset mine though. I read on android central that the update that gives the G2 knock code has a fix for this bluetooth issue.
