The always-useful BetterBatteryStats has received a major update that brings both a new look and full functionality on Lollipop devices. The interface remains fairly minimalistic, but at the least could be described as Material-esque. No hamburger menus or anything like that, but you have the bare bones there.

As you can see, a dark theme is available as well. I'm not a big fan of how the dark background pairs with the vibrant green, but I know some of you really don't like white themes.
A variety of under the hood changes are here, too.
v2.0.0.0
- all new and shiny, with light and dark themes
- Full Lollipop support
- Lots of I18N (see about dialog for credits)
