BatteryBar: The Battery Meter for Windows
Lately, I’ve been looking for a nice little battery meter widget or application to use with my netbooks so I can have a better gauge on how long their last on a single full charge.
The BatteryBar does just that pretty nicely.
It’s got a small footprint, sits on the taskbar and works very well in providing almost accurate information about your laptop’s battery.
The screenshot above is for my HP Mini 311 which I upgraded to Windows 7. It also show how much is the capacity of the battery and the current health (battery wear).
BatteryBar tells me I’m getting around 3.5 hours for a full charge although from experience I was able to squeeze near 5 hours of use on this unit before. Will be running the software on all my laptops now and see how they all compare.
Check out or download the Battery Bar here and let me know how what’s the indicated battery life for you model of laptop in the comments.
Update: There have been questions if this app is reliable. My observation is that the computation of the battery life is based on historical usage. So, if your first 30 minutes of use you play a video then it computes the remaining battery life based on the amount of power consumed vis-a-vis the elapsed time. However, if you changed your usage on the next 30 minutes by just running MS Word, it then recomputes the estimated time remaining based on the power consumption of the last 2 tasks you’ve made with the laptop. As such, you will notice the remaining battery life often fluctuates as you continuously run your laptop.
