Alex Golesh's Battery Level for WP8, an app that gives you a live tile and lock screen status report on your smartphone's battery life, has been updated to version 1.1. Updates include a graph view of your recent battery data, detailed status information (battery time remaining) on the lock screen, a reworked user interface and Live Tile design, the addition of a web based FAQ, and a number of bug fixes.

The app is now commercial, with a price of £0.79 / $0.99 / €0.99, but the free trial allows the basic features to be used indefinitely.

Battery Level for WP8 is not without competition, as we noted in our story on the app last week. In addition to the apps mentioned in the video below (Battery Info, Battery Level, Battery Level for WP8 and Battery Tile), you might also like to check out Battery Status, My Battery, and Battery Meter.
