Your Battery Level is a new application for Windows Phone 8 that allows you to take control of your battery level quickly and easily, using a tile or a screen lockscreen that update periodically.
Unlike similar applications, Your Battery Level allows you to fully customize the tile (or lockscreen) you’re going to use. In fact, the battery level is displayed by means of coloured building blocks and the percentage of the remaining battery. You will be able to decide the colour of all the elements and what you want to be displayed.
With the new update (2.0.1) have been introduced several themes: Goldfish, Tree and Windows Phone style
The apps price is 1.99€ and is available a trial version. What is the limitation of the trial version? Simple, the bricks that show the percentage of charge will go on strike when the charge is below 40%.
