If your Windows 11 laptop is running out of power sooner than you would like, there are several settings you can change to make the battery last longer. The biggest improvements usually come from reducing display power use, limiting unnecessary background activity, and using Windows’ built-in power-saving features.
You don’t need to make every change below. Start with Energy saver, screen brightness, and Power mode, then check Battery usage if the laptop still drains faster than expected.
How to Extend Battery Life in Windows 11
- Click the Start button.
- Open Settings.
- Select System.
- Choose Power & battery.
- Turn on Energy saver when you need to conserve battery power.
- Set Power mode to Best power efficiency when longer battery life is more important than maximum performance.
- Open Energy recommendations and review the suggested changes for your computer.
Those settings give you a good starting point, but the display and the applications running on your computer can also have a major effect on how quickly the battery drains.
Turn On Energy Saver
Energy saver is one of the easiest ways to extend battery life in Windows 11. It reduces power consumption by managing background processes and other system activity. See how to enable Energy Saver in Windows 11 for a dedicated walkthrough.
- Open Settings.
- Select System.
- Click Power & battery.
- Expand Energy saver.
- Choose when you want Energy saver to turn on automatically.

You can also enable Energy saver manually when you know you will be away from a charger for a while.
On Windows 11 version 24H2 and newer, Microsoft calls this feature Energy saver. Some computers running earlier versions of Windows 11 may show Battery saver instead. The purpose is similar, so don’t be concerned if the wording on your computer doesn’t exactly match another Windows 11 PC.
Use Best Power Efficiency Mode
Windows 11 lets you choose how aggressively the computer balances performance against power consumption.
- Go to Settings > System > Power & battery.
- Find Power mode.
- Select Best power efficiency.

This is a good choice when battery runtime is your priority. If you are performing a demanding task and the computer feels noticeably slower, you can switch back to Balanced or another available mode.
The exact options can vary depending on the laptop and its manufacturer. Some manufacturers also provide their own performance and battery controls.
Check the Windows 11 Energy Recommendations
Windows 11 can collect several power-saving settings in one place and recommend changes based on your computer.
- Open Settings.
- Choose System.
- Select Power & battery.
- Click Energy recommendations.
- Review the available recommendations and apply the ones that make sense for you.

Depending on your hardware, Windows might suggest changes involving brightness, screen and sleep timeouts, screen savers, USB devices, or presence-sensing features.
You don’t have to apply every recommendation. For example, you may prefer a brighter screen even if reducing its brightness would save some power.
Lower the Screen Brightness
The display can consume a significant amount of power, so reducing brightness is often one of the quickest ways to improve battery runtime.
You can also go to Settings > System > Display to adjust brightness and other display options.
You don’t need to make the screen uncomfortably dark. Even a modest reduction can help, especially when you use the laptop for several hours.
Make the Screen Turn Off Sooner
A laptop that leaves its display on while you aren’t using it wastes battery power.
- Open Settings > System > Power & battery.
- Expand Screen, sleep, & hibernate timeouts.
- Find the setting for turning off the screen while running on battery.
- Choose a shorter timeout.
You can make the plugged-in timeout longer if battery life isn’t a concern while the charger is connected.
Make Your Laptop Sleep Sooner
Screen-off and sleep settings are separate. Turning off the display saves power, but putting the computer to sleep reduces power consumption much further while you’re away.
In Settings > System > Power & battery > Screen, sleep, & hibernate timeouts, choose a reasonable amount of time before the computer automatically sleeps while on battery power.
A short timeout works well if you frequently walk away from the laptop and forget to put it to sleep yourself.
See Which Apps Are Using the Most Battery
If battery life suddenly becomes worse, an application may be responsible. Our Windows 11 Battery usage guide covers this screen in more detail.
- Open Settings.
- Go to System > Power & battery.
- Open Battery usage.
- Review the applications using the most battery power.

An app near the top of this list isn’t necessarily causing a problem. A program you have been actively using for several hours should naturally consume more power than an app you barely opened.
Look for applications that consume an unexpectedly large amount of power relative to how much you actually use them.
Limit Background Activity for Apps You Don’t Need
Some Windows apps can continue running in the background to receive notifications, synchronize data, and stay up to date. That can be useful, but it also consumes power.
For supported apps, open Settings > System > Power & battery > Battery usage, find the application, select its additional options, and look for the background activity setting.
Power-optimized is generally a good choice because Windows decides when the application can run. Choosing Never can save more power, but the application may stop providing background notifications or updates.
Use Power-Saving Graphics for Apps That Don’t Need Maximum GPU Performance
Windows 11 can use a power-saving graphics preference for individual apps. This can be useful for programs that don’t need your laptop’s highest-performance graphics processor.
- Open Settings > System > Display > Graphics.
- Under the custom options for apps, select the app you want to change.
- Choose Options.
- Select Power saving, then save the change.
This setting is most useful for apps where battery runtime matters more than maximum graphics performance. If an app becomes noticeably slower or has graphics problems afterward, return to the same screen and change its preference back.
Reduce the Display Refresh Rate When Appropriate
Some laptops have displays capable of running at high refresh rates such as 120 Hz or higher. Higher refresh rates can make movement look smoother, but they can also require more power.
- Open Settings > System > Display.
- Select Advanced display.
- Use Choose a refresh rate to select a lower available rate if you want to reduce display power use.
If your computer supports Dynamic Refresh Rate, Windows can automatically adjust the refresh rate based on what you’re doing. That can provide smoother motion when it is useful while reducing power use during less demanding activity, so it may be a better compromise than keeping the display at a low refresh rate all the time.
Turn Off Wi-Fi or Bluetooth When You Don’t Need Them
Wireless connections consume some power, although you generally don’t need to obsess over switching them off every few minutes.
If you know you won’t need Bluetooth for several hours, turning it off can eliminate unnecessary wireless activity. Airplane mode can also be useful when you don’t need Wi-Fi, Bluetooth, or other wireless connections at all.
These changes are most useful when you are trying to stretch the remaining battery as far as possible.
Disconnect Accessories You Aren’t Using
USB devices can draw power from your laptop. External drives, phones, USB lights, and other accessories can therefore shorten battery runtime while they are connected.
If you are trying to conserve power, disconnect accessories that you aren’t actively using.
Some Windows 11 computers also offer an Energy recommendation that stops certain USB devices when the screen is off.
Close Apps You Aren’t Using
You don’t need to constantly close every application on your computer, but demanding programs can consume significant power even when they aren’t the window you’re currently looking at.
Games, video editors, virtual machines, synchronization tools, and applications performing background calculations can be particularly demanding.
If the battery is draining quickly, open Task Manager and check whether an application is using a large amount of CPU, GPU, or other system resources.
Restart the Laptop if Battery Drain Suddenly Gets Worse
If your battery normally lasts several hours but suddenly starts draining much faster, restart the computer before changing many settings.
A malfunctioning application, driver, or background process can sometimes remain active and consume more power than expected. Restarting Windows gives those processes a clean start.
Keep Windows and Your Drivers Updated
Updates can include fixes for power management, drivers, firmware, and hardware compatibility.
Go to Settings > Windows Update and install appropriate Windows updates. For manufacturer-specific firmware and drivers, use Windows Update or the support tools provided by your laptop manufacturer rather than downloading drivers from random driver websites.
Battery Runtime and Battery Health Are Different
There are two different battery goals that are easy to confuse.
Battery runtime is how long the laptop lasts before you need to recharge it. Lower brightness, Energy saver, shorter screen timeouts, and efficient power settings can increase runtime.
Battery health refers to how much capacity the battery retains as it ages. Lithium-ion batteries gradually lose capacity over time, even when properly treated.
If your goal is long-term battery health, try to avoid excessive heat and frequent deep discharges. Microsoft recommends keeping a lithium-ion battery roughly between 20% and 80% when practical rather than repeatedly draining it completely or keeping it at 100% for long periods.
Use Smart Charging if Your Laptop Supports It
Some Windows 11 laptops support a feature called Smart Charging. It can prevent the battery from remaining at 100% charge for long periods when it isn’t necessary.
If Smart Charging is active, your laptop may intentionally stop charging before it reaches 100%. This doesn’t necessarily mean there is something wrong with the battery or charger.
Smart charging is implemented differently by different manufacturers, so the controls may be found in a manufacturer utility rather than in the same place on every Windows 11 computer.
If you are about to travel and need the maximum possible runtime, your laptop manufacturer may offer a way to temporarily enable full charging.
How to Check Your Windows 11 Battery Health
If changing settings doesn’t significantly improve your runtime, the battery itself may have lost some of its original capacity.
Windows can create a battery report that provides information about the installed battery and its capacity. For a focused walkthrough, see how to check battery health in Windows 11.
- Click Start.
- Type Command Prompt.
- Right-click Command Prompt and choose Run as administrator.
- Type powercfg /batteryreport and press Enter.
- Note the location where Windows saves the battery report.
- Open the HTML report in your web browser.

Compare the battery’s current full-charge capacity with its original design capacity. A substantial difference can help explain why an older laptop no longer lasts as long as it did when it was new.
Why Is My Windows 11 Battery Draining So Fast?
Fast battery drain doesn’t have one universal cause. High screen brightness, demanding applications, background activity, high display refresh rates, weak wireless signals, connected USB devices, and an aging battery can all contribute.
Start by checking Settings > System > Power & battery > Battery usage. Then compare what you see there with how you’ve actually been using the computer.
If battery life has declined gradually over several years, battery wear may be more important than a Windows setting.
Frequently Asked Questions
What is the easiest way to extend battery life in Windows 11?
Lowering screen brightness and turning on Energy saver are two of the easiest changes. You can also select Best power efficiency under Settings > System > Power & battery.
Why does my Windows 11 PC show “Battery saver” instead of “Energy saver”?
Microsoft uses Energy saver on Windows 11 version 24H2 and newer. Earlier versions of Windows 11 may use the name “Battery saver” instead.
Does Best power efficiency make Windows 11 slower?
It can reduce performance in some demanding situations because Windows prioritizes lower power consumption. For normal browsing, email, and document work, the difference may be small.
Should I charge my Windows 11 laptop to 100%?
Charging to 100% when you need maximum runtime is fine, but keeping a lithium-ion battery at full charge continuously can accelerate aging. Smart charging can help on laptops that support it.
Is it bad to let my laptop battery reach 0%?
Occasionally running low isn’t unusual, but frequent deep discharges can contribute to battery wear. Keeping the battery in a moderate charge range when practical is better for long-term health.
Why won’t my laptop charge to 100%?
Smart charging or a manufacturer battery-health feature may intentionally limit the maximum charge to protect the battery. Check your laptop manufacturer’s battery or charging utility before assuming the battery is defective.
How can I tell whether my battery needs to be replaced?
Generate a Windows battery report and compare the full-charge capacity with the design capacity. Very short runtime, unexpected shutdowns, or a significantly reduced full-charge capacity can indicate substantial battery wear. A swollen battery is a safety issue; stop using the device and follow the manufacturer’s service guidance.
Summary
To extend battery life in Windows 11, start with Settings > System > Power & battery. Turn on Energy saver, use Best power efficiency when appropriate, review Energy recommendations, and shorten your screen and sleep timeouts.
You can get additional battery life by lowering screen brightness, checking Battery usage for power-hungry applications, limiting unnecessary background activity, reducing display power consumption, and disconnecting accessories you don’t need.
If the laptop still doesn’t last very long after those changes, generate a battery report. An older battery may simply have less capacity than it had when the computer was new.
