How to Extend the Life of a Linux Laptop’s Battery?
On a Linux distribution like Ubuntu, a laptop that lasts 8 hours under Windows 10 frequently only manages 4 hours. Why? Depending on The topic is complicated, divisive, and divisive. Additionally, that’s not surprising considering the enormous variety of laptop and desktop hardware the Linux kernel must handle.
You generally obtain poorer battery life with Linux than with Windows, which is partially explained by Linux users’ propensity to prolong the lifespan of outdated hardware with batteries that have already been through a few cycles.
Don’t get me wrong, though; Linux is energy-efficient when configured for the hardware it uses. You’ll need to make a few additional adjustments if you’re using an off-disk OS with a default configuration, though, in order to extend the battery life on Linux.
In terms of laptops, Linux is infamous for having short battery life. While a laptop running Windows 10 may last up to 8 hours, the same device will struggle to last even 4 hours while running Ubuntu.
It’s true that Linux may be quite power-efficient if it’s ideally matched with the hardware, but if you run Ubuntu off the disc, you’ll need to make some adjustments on your own to extend the battery life.
1. Change Ubuntu’s Built-In Power Settings
Purchasing a powerful laptop does not imply that you will always require such power. You can extend the machine’s battery life by not taxing the processor too much. Select “System Settings” and then “Power.” The power settings can then be changed to suit your needs.
2. Turn Bluetooth Off
Even with Linux, Bluetooth is considered to be a significant energy drainer. Therefore, simply turn off Bluetooth anytime you aren’t using it. You can do this by selecting “off” on the slider and clicking the Bluetooth icon in the system tray.
3. Disable Wi-Fi
Simply switch off WiFi if you aren’t using it; it drains batteries just like Bluetooth does. Turn down WiFi by clicking the corresponding icon in the system tray. Only return it when necessary.
4. Lower the Screen’s Brightness
Reducing the brightness of your display is obviously better for the battery life because increasing brightness requires more power. Either there are brightness adjustment keys on your laptop keyboard, or you may alter the brightness slider by heading to System Settings > Brightness & Lock.
5. Unplug Discs, SD Cards, USB Drives, etc.
Your laptop consumes a lot of power when you have multiple USB drives, smartphones, and SD cards connected. Therefore, you must unplug any unused external devices. Of course, by pressing the eject button provided for the devices, you can safely remove USB drives.
6. Close Apps That Are Not in Use
Even if you aren’t using them, running apps consume RAM and CPU, and some even keep the hard disc awake. Make sure to totally exit out of such apps because they consume your power while running in the background.
7. Steer clear of Adobe Flash
Flash video playback on a Linux laptop uses a lot of battery life. It’s not terrible, of course, but it does matter if you want to extend the battery life. Consider using a browser like Firefox that only displays Flash content when it is requested.

How to Maximize Your Linux Laptop’s Battery?
Use Built-In Power Settings
The power settings should be examined first. Every Linux operating system has some type of power management, allowing you to regulate how the laptop performs when running on battery power. Settings for power management, when plugged in, are also there.
For instance, System Preferences > Power in Ubuntu has these settings.
Adjust the parameters in the Battery Usage column after entering the settings window. You can choose “Suspend if inactive for…”, for instance, and enter a date or circumstance. Alternatively, you may describe what occurs when the power supply is severely low.
Although you might prefer a different alternative, it can automatically cease the activity when the lid is closed.
There is enough information here, albeit not as much as the comparison screen in Windows, to alter how your Linux laptop behaves under particular circumstances.
Reduce the Brightness of Your Screen
By lowering screen brightness, you may extend battery life even further. The simplest method to achieve this is to look for brightness controls on the keyboard shortcuts. However, you’ll have to use the operating system’s controls if your keyboard doesn’t have them.
Locate the brightness slider by going to System Preferences > Brightness & Lock. Find a good balance between readability and a lower brightness by adjusting this. Remember that the easiest way to extend battery life is to avoid using full brightness.
To save power, search for a setting called Dim screen as well. Check the box if it’s an option.
Consider using a lighter desktop background as well. Darker backgrounds use up to 1% more power than lighter ones, according to the Ubuntu team.
Disable Bluetooth and Wi-Fi
Maintaining battery life is always a challenge with connectivity options.
Wi-Fi frequently checks (polls) for new networks to connect to or updates open website tabs, which can significantly drain batteries. The straightforward solution to this is to turn off Wi-Fi.
Click the system tray’s wireless network icon to get started (usually represented as a series of curved lines). To deselect and disable Wi-Fi, click Turn Wi-Fi On in the selection that opens.
The likelihood of problems with Bluetooth on older hardware is higher. If your laptop supports Bluetooth 4.0 LTE, you should be alright because it is a very resource-efficient technology. However, you will notice a greater battery drain if your PC does not have hardware that supports Bluetooth 4.0 LTE.
To prevent this, locate your Bluetooth settings and turn them off (often by clicking the Bluetooth icon in the system tray). Naturally, use caution when utilizing the required Bluetooth devices as they will be turned off immediately.
Another choice is to buy a Bluetooth 4.0 LTE USB dongle and disable earlier Bluetooth gear. Additionally, you may use the airplane mode button on your keyboard to instantly turn off Bluetooth and Wi-Fi.
Close Any Apps You’re Not Using
Maintaining open applications you no longer use is an easy-to-ignore source of battery drain on any device, and Linux is no exception. Your battery can get low if you multitask.
The other open programs will use CPU and RAM even if you are running another app. They are not standing motionless in the distance. These programs could be your browser, email program, Skype for Linux, or anything else. They not only use more CPU and RAM resources, which take power from the battery, but their existence also makes the fan work harder. and where does the fan’s power come from?
Of course, you should uninstall those programs you aren’t using till you do. Exit can be chosen by right-clicking the icon in your taskbar, launcher, or dock. In the interim, these suggestions will be useful if you’re experiencing problems dismissing programs on Linux.
Eject Any Detachable or External Media.
Batteries are used by hard drives. Something has to be supplying power to all of these moving pieces. In the same way, DVD drives operate. However, your battery is built for these gadgets. And your hard disc is pretty much essential unless you’ve converted to a solid-state drive.
However, the situation with portable media is different. You ought to get rid of it if you don’t utilize it. USB sticks and SD cards don’t have their own power supplies, unlike external hard drives and DVD players. Therefore, ejecting those media devices when not in use makes a lot of sense.
But things don’t stop there. It’s not a good idea to rely on this drive unless you anticipate the battery to run out shortly, even though the laptop’s battery should be adequate to withstand DVD use. An abrupt autoload can be avoided by removing the drive from your computer when it’s not in use.
However, you should completely remove the optical drive and swap it out for an SSD for the best results.
Control the Flash Settings (or Uninstall)
Adobe Flash, ah. Flash is still a piece of software that you should use to access some websites, even if the developers at Adobe eventually gave it an end date. Even though it’s not ideal, you’ll probably need to install Flash on your Linux laptop when it reaches end-of-life in 2020.
Of course, running Flash uses a lot of system resources and depletes your battery quickly. What is the response?
There are numerous alternatives. You can simply delete Adobe Flash and browse normally at first. As an alternative, you can configure your browser to prevent automatic playback of Flash-based videos.
Open the menu in Mozilla Firefox and choose Add-ons > Add-ons. Click here to set Shockwave Flash to Never activate. If you occasionally need Flash, you may also utilize the Ask option to turn it on. In this manner, before a video starts playing when it loaded, you will be asked to enable Flash.
Search for Content Settings, then Flash, in Chrome by entering chrome:/settings into the browser’s URL bar. The ability to execute Flash on websites can be toggled here. Another choice is to make the initial inquiry.
It might be prudent to enable both of these settings if you feel that Flash is necessary. Alternatively, you could simply turn off Flash. Additionally, you can use Chrome to display chrome:/flags/ and search for HTML rather than Flash. When enabled, videos won’t play in Flash, and websites are forced to output media in HTML5 rather than Flash.
