Tells me why my phone is awake! Have been using this app for 2 years & it tells me what are the wakelock stuff that's causing my battery to drain. I use Greenify to hibernate apps that refuse to sleep/shut and manage to keep the percentage of battery usage to about 4% an hour  giving my Note 3 about 16 hours of battery life each day! With an accurate battery monitor  I now know when to Greenify the phone!
