[Q] Issues with Bluetooth Related Wakelocks on Lollipop? topic

Ever since I flashed 5.0 to my 900V, my battery life has gone significantly down. Now this can be expected to some extent as I can no longer use Amplify to control NlpCollectorWakeLock (which is one of a few wakelocks going to town on my battery). One of the others is bluedroid_timer, which is part of bluetooth. I did some searching and I saw some other people with the same issue, but no answers. I use a Moto 360 on a daily basis, use bluetooth streaming in my car, and use bluetooth headphones at the gym, so turning off bluetooth isn't really an option. Bluesleep is another one that is spending a lot of time running. Anyone have any ideas? I've read a few threads where people mention this problem, but no one has posted any answers yet. Here is an album of my wakelocks.
