Laptop companies state that battery life will be saved for a long time, but you would see after you bring it home that it does not even stay for 3-4 hours. The battery life depends on the way that we use the laptop.

So it would be better that you know about tips on saving your battery instead of going after the things that most of the laptop companies say.


Using an equation to calculate the battery life

Here is the easiest way to calculate the battery life. You could figure the exact time that a laptop is going to be in power. First, you will have to find the battery capacity by calculating the number of watt-hours. This unit will be measured in either Wh or Whr.

The normal usage of a laptop will spend watts around 10-15. For example, a laptop with a battery of 100Wh for normal usage will work between   7 – 10 hours.  This value is considered to be the time period that you could use for the continuous usage of your laptop.

When the laptops are in the sleep or hibernate mode, it will go dead when the battery percentage is just 10% or 5%. Before you buy the laptop that you prefer, first of all, go through the Wh value of the laptop battery.


How to find the Wh value?

Finding the Wh value of a laptop is effortless. This procedure only needs the model number of the laptop. A mixture of letters and numbers makes the model number. Type this code on Google and search for it. Through the website, you would find the laptop specifications.

If it is an Apple laptop, you will learn about the battery and other technically related data from the Tech Specs, which is on the top side of the website. The other technique that you could follow to get the model number is by looking at the power adapter of the preferred laptop.

In most of the adapters, on its bottom side, you would find the number mentioned. With the help of this number, you can easily find the Wh value.

The mAh (milliampere hours) and V (Walt) is necessary to get the Wh value. What you have to do is you will have to multiply these two values and divide it by 1000 to get the Wh value. You could use an online calculator to get this value.

If you still could not find it using the power adapter you could always see it by switching on the laptop and press the Windows Key + R. Next in the dialog box that appears, type cmd and open the command prompt. There you will have to type powercfg /batteryreport and press Enter. Now you could find details of the battery. You could also remove the battery and see the same information.


Calculating the Watt amount

The Watt amount is decided by the amount of work we do through our laptop.  Just think that your computer is going to be one that will stay alive for 10 hours, but if you are working simultaneously on two software such as Photoshop and Illustrator, the battery power will be reduced to 3 hours.

These tips will help you to decide how to measure the battery life before buying a laptop.
