Your laptop battery can run out of charge unexpectedly due to several reasons. Apart from a faulty battery, screen brightness, background apps, laptop settings, devices connected to your laptop, and power-draining software contribute to faster battery drainage.
If you are wondering how to increase laptop battery life in Windows 11, first analyze how much your laptop is utilizing the power. A few tweaks to your laptop settings can help you achieve a decent amount of time on a single battery charge without any hassle.
This article will share twelve tricks to increase your laptop battery life, show how to analyze which apps are battery-drainers on your Windows 11 PC, and when to troubleshoot the battery issue.
1. Turn On Energy Saver in Windows 11
Energy Saver is among the easiest features for reducing power consumption when a laptop is using battery power. It makes changes to some activities and processes in order to make the computer conserve more power.
To turn it on:
Head to Start > Settings.
System > Power & battery.
Energy saver.
Toggle it on or set it to turn on by default at a specific level of battery.
It can be done also from the Quick Settings panel near the clock on the taskbar.
Once the feature is on, some processes and graphics will be altered in order to reduce power consumption. It is helpful when having a long trip, conversation during work hours or being somewhere without access to electricity.
If the user has an old version of Windows 11, there is a chance that Energy Saver will be named Battery Saver. Options may also vary depending on the Windows version and device. Microsoft recommends checking the official battery-saving guide for Windows.
2. Reduce Your Screen Brightness
The display is one of the biggest energy drains; having it on maximum brightness throughout the day is a waste of battery, particularly on laptops with large or high-resolution screens.
How to fix it:
Go to Settings > System > Display.
There you will see a brightness slider; move it down to the point where you are comfortable reading on the screen.
If you have a laptop with physical function keys, you may be able to adjust the brightness with keys on the top row of the keyboard.
For instance, you shouldn’t set it to the highest level if you are in a room with artificial lighting; the screen will be unnecessarily bright compared to being next to a sunny window. Don’t make it so dark that you have to squint, though – you shouldn’t waste battery life on a brighter display than you need.
3. Set a Shorter Screen Timeout
Your laptop might be showing the desktop even after you’ve taken a walk. Leaving the display on when not in use drains the battery.
Windows 11 allows you to decide how long you want the display to stay on while the laptop is inactive.
Let’s open Settings > System > Power & battery.
Expand Screen, sleep & hibernate timeouts or open a similar screen and sleep timeouts tab.
Set the shorter timeout for the display when on a battery.
Set a sleep timeout to a reasonable value when inactive.
For many people, setting the display to a short time while inactive makes perfect sense. Try a longer period if you like to read long articles without touching a keyboard.
The change will make a noticeable difference if you’re leaving the laptop open while answering phone calls and taking breaks in the middle of the day.
4. Choose a More Efficient Power Mode
Windows 11 offers power modes that balance performance and energy use. If your laptop is set to prioritise performance, it may consume more power than you need for routine work.
To change the setting:
- Open Settings.
- Select System > Power & battery.
- Find Power mode.
- Choose Best power efficiency when battery life matters more than maximum performance.
The exact options may differ by laptop manufacturer and hardware configuration.
For everyday tasks such as writing documents, checking email, or browsing websites, a more efficient power mode is often sufficient. When you need to render video, run demanding software, or complete a processor-intensive task, you can switch to a higher-performance setting if necessary.
You do not need maximum performance all the time. Matching the power mode to your workload can help extend battery life without making routine tasks harder.
5. Find and Limit Battery-Hungry Applications
Some applications use more power than others, particularly when they run continuously in the background. Video conferencing software, cloud synchronisation tools, games, editing applications, and browsers with many active tabs can all contribute to battery drain.
Windows 11 provides a way to review battery usage by application.
To check it:
- Open Settings > System > Power & battery.
- Find Battery usage.
- Review the applications listed and their reported battery consumption.
- Check whether an application is using substantial power in the background.
If an application offers background activity controls, you may be able to restrict its activity through its settings or Windows’ app management options.
Do not disable every background application indiscriminately. Messaging tools, cloud backups, calendar reminders, and security software may need to keep working when you are not actively using them.
Instead, focus on applications that consume significant power without providing a service you currently need.
6. Close Unnecessary Browser Tabs and Extensions
Some laptops offer displays with refresh rates of 90 Hz, 120 Hz, 144 Hz, or even more than this. Always-on refresh rates provide better movement and scrolling displays, but at the same time increase the amount of power consumed. In case your laptop has the option to operate at lower refresh rates, it would be a good idea to switch to it while working on battery.
In order to do this:
Go to Settings > System > Display.
Tap Advanced display.
Check available refresh rates.
If any lower refresh rates are available, select them.
Some devices allow dynamic refresh rates to function depending on current performance. If your laptop has this option, it might yield a perfect combination of quality and energy effectiveness.
Not all laptops support this feature. In some cases, the specs of your panel or graphics allow you only limited adjustments.
Notice that document editing and working with emails should not show much difference so consider this option only if you own a compatible laptop and value battery performance.
7. Reduce Background Syncing and Startup Activity
Applications sometimes start automatically when you switch on your laptop. Others continue synchronising files, checking for updates, or refreshing information when you are not using them.
This activity can consume power and keep the processor busy.
To review startup applications:
- Press Ctrl + Shift + Esc to open Task Manager.
- Select Startup apps.
- Review the applications listed.
- Disable startup for applications you do not need to launch automatically.
Disabling a startup entry does not normally uninstall the application. You can still open it manually when required.
Also review cloud storage, email, and messaging applications. If you do not need constant synchronisation while travelling, adjust the relevant application settings where possible.
Keep essential security tools and applications you rely on running as intended. The goal is to remove unnecessary activity, not to prevent useful services from working.
8. Lower the Screen Refresh Rate When Appropriate
Even though wireless connections consume power, the level of power consumption varies in accordance with the device and the activity being carried out. Wi-Fi consumes more electricity especially when the device is trying hard to keep the connection alive or transfer huge amounts of file sizes.
If you think that you will not need any internet or wireless accessory, then you may consider switching off your connections.
By accessing the Quick Settings panel in Windows 11, you can turn on/off all types of wireless connections at the same time.
Another way to stop wireless connectivity completely, as well as multiple disconnections, is to use airplane mode, although it should be taken into account that this option is suitable only when the connection is not necessary, since you will need to reconnect devices you have already used, such as wireless headphones.
It is also good to cut off accessories you are not using, particularly those charging from the USB port of your laptop.
If there is a need for the internet connectivity during your working hours, such switch-off of the Wi-Fi is not a valuable idea, and it is an option to be considered when no connection is
9. Turn Off Wi-Fi, Bluetooth, and Connected Devices When Not Needed

10. Adjust Video Playback and Graphics Settings
The process of playing videos, editing pictures, playing games, and similar graphic-demanding actions can really use a lot of power. The new Windows version provides features that can lower power consumption for some activities.
To optimize video playback download, go to:
Options in Settings > Apps > Video playback if this is available.
Check different battery consumption levels.
If there is such choice, pick the one that saves the battery as much as possible.
The setting of graphic preferences could also be checked by going to Settings > System > Display > Graphics in some applications.
What effect it will have depends on the laptop’s graphic hardware and the program used. For example, the video editor or a game may still need quite a lot of energy due to the nature of the task.
When travelling, do not forget to close other heavyweight applications when watching a video because it may be more effective than the complicated graphic features.
11. Keep Your Laptop Cool and Maintain Its Battery
Heat affects both power consumption and long-term battery health. When a laptop becomes hot, its cooling system may work harder, and sustained high temperatures can accelerate battery ageing.
To reduce unnecessary heat:
- Use the laptop on a firm, flat surface.
- Keep air vents clear.
- Avoid using it on bedding that blocks airflow.
- Close demanding applications when they are not needed.
- Keep the operating system and manufacturer-recommended drivers updated.
If the laptop regularly becomes very hot or the fans run loudly during simple tasks, investigate the cause rather than assuming it is normal.
Our guide on how to reduce laptop overheating without a cooling pad covers practical ways to improve airflow and reduce excess heat.
Battery care also matters. Lithium-ion batteries gradually lose capacity as they age. If your laptop supports a battery health or smart charging feature, use the manufacturer’s recommended settings. Avoid prolonged exposure to excessive heat and frequent deep discharges where possible.
Microsoft provides additional guidance on caring for your battery in Windows.
12. Check Battery Health With a Windows Battery Report
If your laptop battery drains fast after tweaking all the settings, check its health before buying a new one.
The battery report inbuilt in Windows 11 provides all the significant information about the installed battery, recent usage, and capacity.
To view the battery report:
Launch the Start menu, then navigate to the search bar and type in Command Prompt.
Once you locate it in the search results, right-click the app and select Run as administrator.
In the new window, type the following code:
powercfg /batteryreport
Then press Enter.
After completing the command, check the File Location column in the Command prompt window and copy the address displayed there.
Now, open any web browser and paste the location to view the battery report.
Check the report to view the design capacity of the battery (in mWh). This score represents the rated capacity of the battery when it is new. On the other hand, Full Charge Capacity is the percentage of power the battery can hold at a given moment.
For instance, if the rated capacity is 50,000 mWh while the percentage of full charge capacity is 70%, the battery can hold 35,000 mWh of power.
Keep in mind that this is only a pointer. The battery health analysis is not always accurate since it uses software to generate the results. If you notice that your laptop battery runs out of power rapidly, powers off on its own, or the report shows a reduced capacity, it is best to contact the laptop manufacturer or an approved service center to scan and detect the problem.
Moreover, if the laptop battery is swollen, avoid using the laptop and seek professional help. Avoid trying to remove or puncture a swollen battery.
Why Is Your Laptop Battery Draining So Fast?
You do not necessarily need to purchase new laptops to extend the working time on a single charge, as the proper settings of Windows 11 OS can solve the issue. They are usually related to the display, running background applications, and power mode.
To begin with, you should change the settings related to the Energy Saver, screen brightness, timeout, and battery report. After that, it can be helpful to check the browser, wireless radio, cooling system, and battery health.
The most effective way to increase the discharge rate is to locate the power consumers on your own laptop instead of changing all the settings. In this way, you will leave the functions you use as they are and only disable the actions that shorten the battery life.
If the described changes have little effect, there are some more options to investigate. First of all, it is relevant to check whether your laptop battery is old, as the discharge rate normally increases over time. A reliable source to determine the current state is the laptop’s battery report, which shows how much power was stored at the time of manufacturing.
Further, it can be helpful to see if the laptop is performing any power-intensive tasks, such as online video conferencing or playing graphic-intensive games. Large file transfers, software updates, and applications that consume much energy are also possible reasons. In addition, poor laptop ventilation can increase the discharge rate due to higher temperatures and fan activity. Another cause can be a weak signal of a wireless router, which forces the laptop to spend more energy on maintaining the connection.
Sometimes the reason is a wrong laptop sleep policy that prevents the computer from sleeping even when it is supposed to. In this case, it is recommended to change the default sleep mode and see if the utility can now control the time when the laptop is off. It is also possible that a particular application does not allow the system to sleep; therefore, it is worth checking the laptop’s tasks and programs that run in the background.
Last but not least, a recent software update or some other changes can also be the reason. To find out if it is the case, you should go through the settings of Task Manager and Windows Update and locate the suspicious program or update. If you find it, there is a high probability that the file is malfunctioning or corrupt, and restarting the laptop might fix the issue.
