Why Does My Laptop Battery Drain So Fast?

Chris Campbell13 Mar 2022

Does your laptop's battery drain quickly? There are several possible causes, and thankfully, many of them are easy to fix.

One of the most common causes of a laptop battery that drains quickly is an outdated battery that needs to be replaced. Furthermore, while running resource-intensive apps or when the battery settings are not optimal, your battery may deplete fast. 

This problem can potentially be exacerbated by peripherals that demand less or more power to function on your laptop. When the laptop's power button led is illuminated, it uses electricity. Although these are tiny amounts, they can pile up over time. Or you may have a single peripheral that is rapidly draining your battery without your knowledge.

Identifying the cause of your laptop's battery dying so quickly is critical to resolving the issue.

Why Does My New Laptop Battery Die So Fast?

Imagine this: your laptop battery is brand new. You've been browsing the web for about an hour when you get a notification telling you to plug your laptop in before it dies. If modern laptop batteries can retain a charge for several hours, you might be puzzled as to why your laptop battery dies so quickly.

Various default settings, applications, and programs on your laptop that are intended to improve your experience will frequently drain your battery needlessly. Settings like brightness and power plan, as well as other elements like bloatware and background programs, might all be adding to your battery dying rapidly.

By adjusting these settings, you should be able to protect your battery from dying too soon. However, if the battery continues to deplete too rapidly, there might be a problem with the battery itself.

Laptop Battery Drains Fast: Fix the Issue

Is your laptop's battery depleting in a much shorter time? A laptop battery might deplete quickly for a variety of reasons. Factors such as excessive display brightness, the system installing a significant number of unwanted apps and processes, an outdated battery, etc.  Whatever the cause, there are certainly solutions to your laptop battery dying quickly.

Adjust the brightness of the screen.

The display is one of the main components that draw power from the battery. As a result, adjusting this setting is the first step in resolving your laptop battery draining quickly. The brightness settings could be found on the taskbar shortcuts or by using the function keys to boost or reduce the brightness.

Alternatively, you may do the following:

  • Go to Settings, then click System.
  • Navigate to Display and adjust the screen brightness to your liking.
  • Keep in mind that setting it too high can cause your laptop's battery to drain faster.

Turn off the laptop keyboard's backlight.

Backlighting on the keyboard is a feature seen in certain high-end laptops. While it might assist you in typing in the dark, it can also pose complications such as the laptop battery emptying quickly. To correct this, use the keyboard keys Function + F5 to modify the brightness.

You may also do it from the settings:

  • Navigate to the Control Center of your system.
  • Go to Mouse and Keyboard.
  • Disable this feature by going to the "Keyboard Backlight" section and unchecking the box.

Modify the power settings.

Any recent changes to your system's Power settings may also be to blame for laptop battery issues. Theoretically, it could happen with any brand of laptop and is easily fixed:

  • Go to the Settings menu.
  • Choose System.
  • Adjust the settings for sleep and screen time when the system is turned on or hibernated by clicking Power & Sleep.
  • You may also navigate to "Additional Power Settings" from here if you want to run an optimized or balanced plan on the laptop. You can also select to establish your power plan.
