Here's an app that should excite some of you new Windows Phone 8 owners out there: Battery Level for WP8 by Alex Golesh. The first of its kind, as far as we know, the app allows you to constantly keep abreast of your battery life on your WP8 device with a simple Live Tile.
Just pin the app to your Start screen and choose one of three sizes (small, medium and doublewide) to suit your needs. The doublewide will even display the charging state (discharge or charging) in addition to the battery icon and percentage left. Oh and the app can also display a battery icon and percentage on the Lock screen. Yup, just head to Settings and choose it as one of your five options and you'll be good to go.
