Developed for the Google Desktop platform, Battery Meter is a small gadget that shows you the current lifespan of your laptop's battery, right on the desktop.
It can be easily installed and set up, even by users with little or no experience in such tools.
The interface of the app is based on a very small frame. If you undock it from the sidebar, you can use the mouse cursor to drag it to any spot on the screen.
Battery Meter shows if your laptop is currently plugged in. It changes its color as the battery meter decreases, from green (fully charged) to red (almost discharged). Unfortunately, the gadget does not come with any customization options of its own.
But, thanks to Google Desktop, you can make the frame stay on top of other windows, zoom into it, as well as hide or collapse it. The app does not interfere with the runtime of other active processes, as it uses a very low amount of CPU and system memory.
It has a good response time and worked smoothly during our tests, without hanging, crashing or popping up error dialogs. All in all, Battery Meter delivers a simple solution to checking out your battery's current level.
