Battery Widget

Battery Widget is not an app; it’s a simple desktop tool for monitoring you battery-life

As easy as it sounds, this is not an app but a 1x1 widget to put on your screen and see at a glance how much juice your battery has left. What's more- and this is really interesting- if you tap on the widget, it will show a battery with 5 buttons:

"Battery" Button : This opens the Battery Monitor screen where you can see how much battery each Android system feature drains (screen, wifi, apps, etc.)
"Display" Button : This opens the Display settings where you can set the font style, brightness, saturation, etc.
"GPS" Button : This opens the Location and Security settings
"Wi-Fi" Button : This enables/disables Wi-Fi.
"BTButton ": This opens Wireless and Network settings

These extra features allow us to carry out a comprehensive control of our battery life, by configuring the main processes that make the battery run out fastest.

Battery Widget has been developed by Gekyouup (mippin.com), an app developer focused on widget performance. They've launched lots of similar apps for a wide variety of issues.

Battery Widget is a truly recommendable way to monitor your battery life, not just to see how much is left. Thanks to the shortcuts to the main settings options, we can increase battery life in just a few taps of the screen.
