When you first purchase your laptop and fully charge the battery thereafter, It runs at It's optimal state for quite a while. However, over time, It Inevitably decreases In performance, and does not hold It's charge capacity as per It's brand new state. This Is due to wear & tear, and a few other factors. It's very Important to know the condition of your battery, so In this tutorial, I will show you how to view the current status and health of your laptop's battery.
If you're the type of user who's on the move and relies on the power of your laptop's battery to perform your computing tasks, you'd want to make sure It serves you well. Windows Is very limited with the amount of battery Information It provides and as such, I will demonstrate how to view It's voltage, charge & discharge rate, capacity, health and most Importantly, the worn-out rate.
To achieve this, I will use a neat little tool named BatteryInfoView, that can be downloaded from the official website. So without further delay, let's get this tutorial started.
Once you've downloaded the tool, simply execute It, and you'll see the following Information pertaining to your laptop's battery. Obviously, your details will be different to mine.
For further analysis, you can export the details, by selecting the View tab, and then clicking HTML Report- All Items as Illustrated below.
The report will be generated to your current browser, In the form of a .html file.
You can also click on each entry and view It's value. In my case, I've clicked the Charge/Discharge Rate, and It's value Is listed directly beneath It.
The most Important part, Is the battery's worn-out rate. The formula to calculate this, Is as follows:
Designed Capacity - Full Charged Capacity / Designed Capacity
In my case, the Designed Capacity Is 48, 944. The Full Charged Capacity Is 42, 438. The difference between the two, Is the worn-out rate of my laptop's battery. So In terms of a percentage figure, I'll use the above formula as per below.
48,944 less 42,438 divided by 48,944 = 132927427
The first two figures In the result of the above calculation, Is the percentage worn-out rate of my laptop's battery which Is 13%. You can calculate yours, by using the same equation.
When used In the right context, the BatteryInfoView Is a very powerful tool to view, and keep track of your laptop's battery. The good thing about It, Is that It provides the details In real-time, by updating the Information every 30 seconds.
Be sure to keep the tool on hand, and look for any changes that may have an Impact on the health of your battery.
