BattCursor shows the battery charge in percent directly under the mouse cursor, and offers many other battery-saving features, among others, dim down the display brightness for inactivity, automatically disable the Windows Sidebar and Aero Glass and much more.
And the best part: It costs nothing, worth seeing ;)
Since BattCursor supports all features of the windows energy symbol a frequently
question is how to disable it. This tutorial will help you to replace the windows energy
icon with that from BattCursor.
To disable the windows energy symbol make a right click on your start bar
and then click on properties.
Here click on the tab Notification Area and uncheck the box for
System icons - Power as shown on the picture.
In the BattCursor settings you can choose when the system tray symbol should
be shown (always, only if battery present or only if running on batteries).
