Laptop battery draining fast in Windows 11: how to fix it

Applies to: Windows 11 laptops, 2-in-1s and tablets whose charge falls faster than it should, whether in use or asleep. Menu names below are from Windows 11 version 24H2 and later; older builds call Energy saver Battery saver.

Drain or wear? Rule out the battery first

Two different problems look the same from the taskbar. A worn battery holds less charge than it did when new, so even a well-behaved laptop runs out sooner. Drain means something is drawing more power than it needs to. Settings can only fix drain.

Before you change anything, spend two minutes on our battery health guide, which shows how to compare full charge capacity with design capacity in the battery report. If the battery has kept most of its original capacity, carry on here. If it has lost a large share, settings will only stretch the runtime a little, and a replacement is the real fix.

Fix 1: Find the app that uses the most battery

Windows keeps a record of which apps drew power. Microsoft’s battery saving tips point to it as the place to start:

1. Open Settings > System > Power & battery and select Battery usage.
2. Look under Battery usage per app for apps near the top of the list, especially ones you weren’t using.
3. Select More options (the three dots) next to an app, then Manage background activity.
4. Change Let this app run in the background to a more restrictive setting, such as Never, where the app offers that choice.

Not every app lets Windows limit it this way. Desktop programs that install their own updaters or sync tools often ignore the switch, so for those, look in the program’s own settings for an option to quit when its window is closed, or stop it from launching at sign-in (Fix 5).

Treat the list as a clue rather than a verdict. A browser always ranks high because it’s where you spend your time. An app you rarely open that still sits near the top, such as a cloud backup, a game launcher or a chat client, is the more likely culprit.

Fix 2: Power mode and Energy saver

Both settings live on the same page, Settings > System > Power & battery, and they do different jobs.

• Power mode. Microsoft’s power settings page describes Best power efficiency as the mode that holds back background activity on battery and when plugged in. If yours is set to Best performance, the processor is allowed to run faster and hotter, which costs charge. Some laptops set different modes on battery and when plugged in, and Microsoft notes the options depend on the hardware and maker, so the list can be shorter on your PC.
• Energy saver. It dims the screen and limits background processes once the battery runs low. Expand the section to choose the battery level at which it starts on its own; raising that threshold gives you the savings earlier in the day. To keep it on until the next time you plug in, turn on Always use energy saver, or switch it from the battery icon in Quick Settings.

Energy saver has a side effect: it can slow apps that need the processor, and on some builds it can also put Microsoft Edge into its own efficiency mode. If a program feels sluggish on battery, our Efficiency mode guide explains which switch is responsible.

Many laptop makers add a quiet, eco or battery profile in their own app, and that profile can override the Windows power mode. If the Windows setting seems to make no difference, check that app too.

Fix 3: Brightness, refresh rate and screen timeout

The display is often the biggest single power draw on a laptop, so small changes here add up.

• Brightness. Go to Settings > System > Display and lower the slider under Brightness. Microsoft suggests turning off automatic and content-based brightness changes if they keep pushing the level back up, then setting it by hand.
• Refresh rate. A 120 Hz or 144 Hz panel looks smoother but uses more power. Under Display > Advanced display, pick a lower rate in Choose a refresh rate, or turn on Dynamic refresh rate where it appears, so Windows drops the rate while you read or type.
• Screen and sleep timers. Expand Screen, sleep, & hibernate timeouts on the Power & battery page and shorten the on-battery times for turning off the screen and going to sleep.
• Dark mode. On OLED screens, dark pixels draw less power. Choose Dark in Settings > Personalization > Colors, under Choose your mode. On a typical LCD panel the gain is small.

If you’d rather not set each one yourself, Settings > System > Power & battery > Energy recommendations lists suggested changes and can apply them all at once. Microsoft’s energy recommendations page says the list varies by device: presence-sensor and ambient light options only show on laptops with that hardware.

Fix 4: Graphics and video playback

A laptop with a separate graphics chip (from NVIDIA or AMD, alongside the processor’s built-in graphics) burns charge quickly if an app wakes that chip for no reason. Windows lets you choose per app:

1. Open Settings > System > Display > Graphics.
2. Under Custom options for apps, select the app, then Options.
3. Choose Power saving and save. Leave games and video editors on the faster option if you need it, and change only apps that don’t need much graphics power, such as a chat client.

If you watch a lot of video on battery, go to Settings > Apps > Video playback and choose Optimize for battery life under Battery options. The box below it lets video play at a lower resolution on battery, which saves more.

Graphics drivers from the laptop maker sometimes add their own power controls, such as an option to switch off the separate chip on battery. Names differ by maker, so look in the driver’s control panel or the maker’s app.

Fix 5: Cut startup apps and stray processes

Every app that starts with Windows can keep working in the background for the whole day. Open Settings > Apps > Startup and turn off anything you don’t need from the moment you sign in. Our guide to where startup programs live covers the places that page doesn’t show.

Next, press Ctrl + Shift + Esc to open Task Manager and sort the Processes tab by CPU, then by Power usage. A process that stays high while you’re doing nothing is worth a closer look: end it if you recognize it as safe to close, or update or remove the program it belongs to. If the busy process is a Windows component, such as indexing or an update, it usually settles after it finishes, so give it time while plugged in.

Restarting also helps. Microsoft lists a restart as a step that can fix issues that shorten battery life, because it clears apps and drivers stuck in a busy loop.

Fix 6: Battery drains while asleep or with the lid closed

Most recent laptops use Modern Standby rather than the older S3 sleep. The PC drops to a low-power state but can stay connected, so a small loss overnight is expected. A large loss means something kept it awake.

Run a sleep study. Open Command Prompt as administrator and run:

powercfg /sleepstudy

Microsoft’s Modern Standby SleepStudy guide explains that the command saves an HTML file named Sleepstudy-report.html in the folder the command window is in, covering the last three days. To look further back, add /duration 7 for a week; the guide gives 28 days as the most it can cover. Sessions shorter than 10 minutes aren’t recorded.

In the report, each standby session shows how much energy it used per hour and, for each one, a short list of top offenders: the components that were busy the most. The colors help:

• Red marks a drain of 1% of the battery per hour or more, or a session where the chip spent under 80% of the time in its lowest power state.
• Yellow marks a middling drain or a low-power share between 80% and 94%.
• Green means the session behaved as expected.

An offender with a network adapter name points to Wi-Fi or Bluetooth activity; a named app or service points to background work. Update that driver, limit that app as in Fix 1, or turn off its background permissions. Our sleep states section in the won’t-sleep guide explains how to see whether your PC uses Modern Standby or S3.

Check the lid and USB settings. If closing the lid only turns off the screen, the laptop stays fully on. Open Control Panel, go to Power Options and select Choose what closing the lid does; set the on-battery choice to Sleep or Hibernate. Hibernate saves the session to disk and uses almost no power, which suits a laptop that will stay in a bag for days. On laptops that offer it, the energy recommendation Stop USB devices when my screen is off to help save battery stops plugged-in USB devices from drawing power while the screen is off.

Fix 7: Energy report, troubleshooter and updates

Energy report. In an administrator Command Prompt, powercfg /energy observes the system for one minute and then lists energy efficiency problems, such as a USB device that never suspends or a power plan setting that keeps the processor busy. Microsoft’s powercfg reference says to run it with no programs or documents open. It reports configuration problems, not battery wear.

Power troubleshooter. Go to Settings > System > Troubleshoot > Other troubleshooters and select Run next to Power. It checks and resets power settings that commonly shorten runtime.

Updates and drivers. Install everything in Settings > Windows Update, including drivers under Advanced options > Optional updates. Graphics, chipset and Wi-Fi drivers, along with the laptop’s firmware (BIOS), all affect how well the hardware reaches its low-power states. Get firmware from the maker’s support site, read its release notes, and keep the laptop plugged in until the update finishes.

When to look at the hardware instead. If the laptop loses charge while fully shut down, or the battery percentage jumps or drops suddenly, the battery or its charging circuit may be at fault. Our plugged in, not charging guide covers battery driver and charger checks. If the case, keyboard or touchpad starts to bulge, stop using the laptop and contact the maker, because a swollen battery is a safety risk.

Known issues

As of November 2026, Microsoft’s Windows 11, version 25H2 known issues and notifications page, last updated on November 5, 2026, lists no issue with battery life, sleep, standby or charging. The only item not fully resolved concerns USB audio devices.

If drain began right after a monthly update or a new driver, check that page again; Microsoft adds issues there as they’re confirmed. Rolling back a recently updated graphics or Wi-Fi driver in Device Manager is a reasonable test while you wait for a fix.
