The Top 7 Reasons Your Chromebook’s Battery Dies Fast (Explained)

Reasons Your Chromebook's Battery Dies Fast

ChromeOS laptops have long battery life and can keep you going for an extended time. This general norm is not without exception. For example, Chromebook batteries might deplete quickly for some apparent reason at times. We will cover all this in detail, but first, What are the reason your Chromebook’s battery dies fast?

Some of the reasons your Chromebook battery dies fast are using many peripherals, leaving your Bluetooth and Wi-Fi on, having an increased brightness level, and so many apps are being executed simultaneously. Other reasons include working with high-efficiency websites, having your laptop always running, and having a faulty battery.

Why is the Chromebook battery draining fast?

The first step to fixing your Chromebook battery is to figure out what’s causing it to run out.

1. Peripherals

Peripherals might lower the battery life of your Chromebook by up to 30 minutes when it is running on battery power. We may use the example of a nine-hour laptop battery life. The battery life will be reduced to eight hours and thirty minutes if you use a lot of peripherals. Disconnecting your peripherals while not in use can help you save battery life.

2. Bluetooth and Wi-Fi

If you’re not using Bluetooth or Wi-Fi, turn them off completely. Wired connections use a lot of battery power, so turn them off if you don’t need them.

You may also utilize offline mode in many Google apps to refresh your memory. For example, you may use Google Docs and Google Sheets while you’re not connected to the internet. So when you reconnect online, you may update your Google cloud files with the most recent modifications you made while offline.

3. Setting the brightness level

Your Chromebook’s brightness settings may or may not be able to be reduced based on the current lighting conditions in your room. If you’re working late, though, you might want to experiment with adjusting the screen’s brightness. This is healthy for your eyes and your battery life simultaneously. Adjusting the brightness may be done by selecting the time symbol and using the slider. Alternatively, you can enable the Night Light feature.

4. Apps and procedures are being executed.

Just close the software or application if you don’t need it anymore. You’ll be wasting your battery life if you leave it running in the background all day. For example, suppose you recently completed an online game and took a 15-minute break. You may launch the Task Manager by pressing the Shift and Esc keys simultaneously. After that, switch to sleep mode.

Batteries drain more quickly if many browser windows are open at once.

5. Work with high efficiency.

Too many high-intensity tasks running in the background on your Chromebook might drain its CPU power. Also, due to the increased temperature, your battery may overheat and discharge more quickly than usual. Keep your Chromebook cool if you know you’re going to be using many resources with resource-intensive software. Then, disable your VPN and see if there are any noticeable changes.

6. Your laptop is always running.

The third-minute break is a good time to shut off your computer altogether. Yes, you can put your Chromebook into sleep mode, but it will still use some battery life. If you shut it down fully, nothing will draw power from your laptop’s battery for the next 30 minutes.

7. Batteries that are faulty.

The battery on your Chromebook may be dwindling at an alarming rate, which may suggest that you need to get a new one. If you’ve been using your phone for three years, you may find that the battery doesn’t last as long. As a result, it’s important to remember that the battery life of your Chromebook might vary greatly.

You may use the battery test command in Crosh to see if you need a new battery. For example, if the health of your battery is less than 80%, it’s time to get a new one because its performance has declined dramatically. 

What is Crosh used for?

“Chrome Shell” is the name given to the command-line environment offered by Chrome OS, called Crosh. This is a command-line tool like Command Prompt on Windows or Terminal on macOS devices. Many commands may be executed straight from ChromeOS using Crosh. 

What takes up the most battery life on a Chromebook?

On a Chromebook, the display often consumes the most battery power. Therefore, when you are working late, you should reduce the brightness of your screen to preserve battery life.

Why won’t my Chromebook hold a charge?

If your Chromebook won’t charge, it’s probably because the battery is bad and has to be replaced. You’ll notice that your battery drains much more quickly if your battery health dips below 80%. To check the health of your battery, type “battery test” into a Crosh terminal window.

How to Fix a Slow or Draining laptop Battery

Your laptop’s battery life may have decreased over time because of something you’ve been neglecting for a long time, not the quality of the laptop. Unfortunately, all of these are depleting your laptop’s battery life with the routine things you thought were simple to complete on it. As a result, battery life is shortened, and overall performance suffers. Because of this, there are a few simple techniques to extend the life and performance of your laptop’s battery.

Ways to save your Chromebook’s battery life. Here are some easy ways to enable the long life of the Chromebook battery: 

1. Reduce the screen’s brightness to one-third of its default setting.

Reduce the screen’s brightness to one-third of its default setting. The two keys on the top row of your keyboard may be used to either reduce or boost the brightness of the screen.

The display consumes a significant portion of the battery’s power, so lowering the brightness to a more comfortable level can help you get the most out of your battery.

2. Avoid battery-draining software upgrades.

To conserve energy and CPU resources while Chrome updates in the background, avoid installing any other software updates.

3. Unplug any unnecessary gadgets.

Remove other devices, such as phones that are charging or headphones, from the battery to extend the battery’s life. Then, when the Chromebook isn’t being used, but you still need a power source, you may use the Chromebook to power other devices. 

4. Disable Bluetooth.

Bluetooth is an effective yet power-hungry technology. Therefore, you should turn off the Chromebook’s Bluetooth if it is not being used. To disable Bluetooth, go to the Settings window, click the Bluetooth icon, and click “Bluetooth Disabled.”

5. The screen should be locked while not in use.

Chrome OS was created with a long battery life in mind. Therefore, Chrome OS does not include a built-in option to modify the time before the Chromebook goes to sleep. In addition, using a screensaver drains battery life, so they are not supported. Instead, enable screen locking to save battery life. 

6. Close down any unnecessary websites or programs on your computer.

Most online sites and mobile applications often refresh to keep their content up-to-date. You may use the Windows Switcher key to examine what applications are currently running. Close all unnecessary apps that are currently running. You may display the most battery-intensive online sites and programs in the Battery Usage section of Chrome OS. Click on the status bar and then select Settings to locate this. 

This will bring you to the Settings page. Next, click on the battery link under the device section. In the new window, you’ll see a list of the websites and applications you’ve visited, along with a battery usage percentage.

7. Use the Microsoft Edge browser.

Microsoft’s Internet Explorer has inspired a slew of parodies. However, compared to Google Chrome, Firefox, and Opera, Microsoft believes that Edge saves battery power significantly.

8. Don’t wait for the battery to run out.

In either case, most individuals attach the laptop’s charging cord only when the battery is nearing its end of life. Refrain from using any of the following products to help prolong the life of your battery. Reduced charging capability occurs when the laptop’s battery is less than 20% full.

9. Turn off the keyboard lights.

You don’t need a keyboard backlight unless you have a red-backlit laptop or work in a dark room. By pressing a keyboard function key or by using the Windows Mobility Center, you may disable it.

10. Longer the battery, or better the performance.

If you don’t do a lot of work at the office or don’t use heavy software, it’s best to switch between these two power modes: best battery life and best performance. Then, when you click on the battery icon in your taskbar, you need to find the right balance between saving battery life and getting the most out of your PC.

11. A battery saver

As with your Android and iOS devices, laptops also go into battery saver mode when the battery level drops below 20%. There is a simple way to see if the battery saver is on: go to Settings > System > Battery. As soon as you turn on the battery saver mode, you won’t be able to sync your email and calendar, get push notifications, or run apps in the background.


There are several reasons why a Chromebook’s battery is quickly draining. Even when you’re not actively utilizing your wireless connections, such as keeping Bluetooth and Wi-Fi enabled. High-intensity apps drain your battery since they utilize a lot of CPU power. As a result, you’ll find that your Chromebook won’t be able to charge correctly.
