Thank you! This maybe a year old, this may list an older Droid OS (KitKat vs Lollipop), but it is just as relevant then as it is right now! This is exactly the same problem as I have been facing and be darned if I could find an answer, that is until I found this tonight as the first hit from Google Search, and THANK YOU! LOL
This problem has been driving me absolutely NUCKEN FUTS! For last last couple months, and probably since KitKat, I couldn't tell you for sure but it's been going on for a long time and everytime I thought I found a post explaining it, YES....... um, no, that wasn't it... It was such a let down everytime. But not this time! BINGO! I can't thank you enough for this post. My battery thanks you and I thank you! Great job!
