Laptop Battery Dying Fast: Reasons and Quick Fix

Laptop battery dying fast is a common problem among laptop users. It can cause a lot of problems, especially when it comes to working on urgent projects. You might find that your battery is dying fast, even when you have not used it for a long time. It could be due to some software issues which can easily be solved.

The expected battery lifespan of a laptop is three to five years. Therefore, there are a few things you need to know if your laptop battery is deteriorating quickly and is less than five years old. This article will guide you through all the steps that need to be taken for you to solve this problem.

So, Why Does My Laptop Run Out of Battery So Fast?

There are many reasons why your laptop runs out of battery so fast. Here are some of the most common reasons:

  • Many people keep their laptop’s keyboard backlight turned on even when they aren’t using their laptops in dark places like libraries—while this might seem like a good idea, doing so can significantly reduce your battery life. The backlight uses a lot of power, so if you turn it off when not needed, you’ll get more time out of a single charge.
  • You run background applications, such as antivirus software and other security programs. These applications constantly scan your system, which consumes a lot of power.
  • Keeping your battery on High-performance mode: If you have an older laptop with an Intel processor and Windows 7 installed, there’s likely an option in your system settings called “High performance” mode (also known as “Better battery”). This mode allows the computer to prioritize performance over efficiency, which may consume more power than average while running applications.
  • You’re running too many apps at once, causing an energy drain on your CPU (central processing unit), which runs all your applications, including the operating system itself.

Quick Fixes to Retain Power Longer

If you’re experiencing a laptop battery dying fast, there are several things you can do to prolong the life of your battery. Here are seven tips on how to make your laptop battery last longer:

Change The Battery

It should be your first fix. If your laptop battery is old or has been used for many years, it may be time for a replacement. A laptop battery is designed to last for roughly three years. If yours has lasted longer than that, it’s time to replace it.

Adjust Brightness Settings

Laptops use more power when they are running at high brightness levels. Turn down the brightness settings on your computer to help save power and extend your battery life. If you need to use your laptop outside in bright sunlight, consider investing in an external keyboard and mouse that don’t require batteries. Some newer laptops even have backlit keyboards that adjust the brightness to match surrounding light conditions.

Disconnect Unnecessary Peripherals

Connecting an external device, such as an external hard drive or printer, draws power from your laptop’s battery even when the computer is not using it. Disconnecting these devices will save power and extend the life of your battery. You can also try shutting down any unnecessary apps running in the background or closing programs that appear on your taskbar (Windows) or dock (Mac OS X).

Adjust The Power Plan

You can save your battery by making changes to your power plan. Click on Start and then Control Panel. On the left pane, click on Hardware and Sound. Double-click Batteries in the Device Manager window to select it. Next, choose Properties by performing a right-click on your battery. Uncheck the box next to “Allow The Computer To Switch Off This Device To Save Power” by selecting the Power Management tab.

Turn Down Your Backlit Keyboard

This one is pretty simple: backlit keyboards use more power than non-backlit keyboards. If you have an option between two laptops (one with a backlit keyboard and one without), opt for the one with the non-backlit keyboard.

Cool It Down

Heat is another common cause of fast-dying laptop batteries, so keeping them cool can help increase their longevity. Try not to keep your laptop on your lap while using it, and make sure there’s plenty of room around it so that heat can escape easily into the surrounding air. You should also avoid putting your laptop in direct sunlight or near any other heat source (like heating vents) while working with it.

Close Background Apps And Programs

The more programs or apps run in your computer’s background, the more resources they take up — including CPU cycles and memory — which means fewer resources for other processes like playing music or video games. Close out all unnecessary apps and programs when not in use to keep energy consumption low and extend battery life!


You should be able to solve the issue using the above quick fixes. It might be time to buy a new laptop battery, though, if you’ve tried all of these quick fixes and your battery is still not holding a charge. Before getting rid of the issue, you could try consulting an expert.
