My battery remaining times keeps changing

[Ryan83]

Hi, 

I was wondering, I just purchased a laptop a few days ago, I had to go into the bios to enable the showing of battery time remaining.

I've noticed that the time remaining keeps changing, sometimes its 8 hours, then it drops to 3.5  etc within a short amount of time.

I was wondering if this was normal or could I have a faulty battery.

Thanks.

Hi! @Ryan83,

Please share the product number of the PC to assist you better.
 

As you know that the battery is consumable part and everyday usage makes the battery decrease its shelf life.

Eg: A battery on a smartphone decreases over a period of time. The same way the life of the laptop battery decreases over a period of time.

To increase the battery life on your laptop try the steps recommended below.

Make sure no applications are running in the background.

You can check the applications running in the background by going to task manager on your PC.

 
Try updating BIOS and chipset drivers on the PC to the latest version and check if it helps.

Also, try calibrating the battery and run a battery test on the laptop.

Battery cycle life is the total number of discharge-charge cycles (Figure 1) a battery yields before it can no longer hold a useful amount of charge. Estimating the cycle life of a rechargeable Li-Ion battery is difficult because cycle life is affected by the average operating temperature of the battery and its energy discharge rate.
Basically, higher temperatures and higher energy discharge rates decrease battery cycle life. The operating temperature of the battery depends on the air temperature as well as the heat generated by the notebook itself and by its immediate environment, such as a docking station. The energy discharge (drainage) rate depends on the type of applications running on the notebook and by its power management settings.
For example, running compute-intensive applications such as CAD, gaming, and DVD movies drains the battery faster and decreases its cycle life more than running word processing applications.

Hope this answers your query!

Have a great day! 🙂
