Can someone recommend a tool/app that I could use to get a better understanding of what my battery is doing and which app are draining it? I have a Droid Turbo, running 4.4.4 and was looking to monitor the battery for the next month or so to get an idea of what's going on. I'm assuming there's something "better" than the built-in Battery function, but maybe I'm mistaken. Thanks in advance.
