How To Fix Battery Drain Issues In Windows [Easy Guide]

Battery depletion appears to be a recurring issue for some Windows users. If this is happening to you, don’t worry; assistance is on the way. This post will teach you how to resolve battery drain issues and extend the life of your battery.

Why Your Windows PC Battery Drains Fast.

There are various reasons behind battery drain issues on Windows. The most common are:

• Multiple apps running in the background.
• PC is in fast startup mode.
• High screen brightness on your PC.
• PC’s display is set for a high refresh rate.
• High-performance graphics for apps.

How to Check Your Battery Health.

A PC’s battery backup largely depends on the health of its battery, which is why you should check your system’s battery health first to assess whether it’s actually the cause of the poor backup.

1. Press Win + X and select “Windows Terminal (Admin)” from the menu.
2. Type the following in the command prompt and press Enter.
   powercfg /batteryreport /output "c:\battery_report.html"
3. Your battery report will be saved in your “C:\” drive. Open it from there.
4. Scroll down the battery report until you find the “Battery capacity history” section. The “Full charge capacity” displays the present capacity of your battery to hold power, while the “Design capacity” shows the maximum power the battery is designed to hold. Over time, the full charge capacity of the battery will decrease, but if it is much lower than the design capacity, your battery’s health is poor.
5. You will see the “Battery life estimates” section below the “Battery capacity history” section. This will give you an idea about the battery life at full charge compared to the design capacity of your battery. Drastically reduced battery life at full charge also indicates poor health of your PC’s battery.

How to fix Battery drain issues in Windows.

1. Run Power Troubleshooter.

You can use Windows’s built-in power troubleshooter tool to find and resolve battery-related issues that might be affecting your system.

• Press Win + I to open “Settings” on your PC.
• Click on “System” from the left sidebar, then select “Troubleshoot” on the right. In Windows 10, you’ll need to go to “Settings -> Update & Security” to find the relevant option.
• Click on “Other troubleshooters.”
• Scroll down until you find the “Power” option and click “Run.”
• Go through the troubleshooting report to check for any issues and tweak settings accordingly.

2. Choose the Right Power Plan.

Your Windows 11 PC has three power modes: “Best performance,” “Balanced,” and “Best power efficiency.” You’ll need to switch to the last one if you want to conserve the most battery life. “Best power efficiency” mode works by lowering the system’s performance. (In Windows 10, it might be called “Best battery life.”) On the other hand, if you want your PC to automatically adjust energy for optimal performance according to the tasks you’re doing, you can choose the “Balanced” mode.

• Go to “Settings -> System.”
• Scroll down the tabs on the right side and click on “Power & battery.”
• Click on “Power mode” to reveal a drop-down menu and select the “Best power efficiency” option.

3. Configure Battery Saver.

The “Battery Saver” feature conserves power as your laptop battery reaches critical levels. By default, your device will turn “Battery Saver” on automatically when the battery hits 20%.

4. Customize Display Settings.

You can also tweak your PC’s display settings to prevent it from consuming a lot of power and draining your computer’s battery.

5. Close Background Apps.

Apps running in the background may be another cause of battery drain in Windows. Make sure you close them properly to save battery power.

• Press Ctrl + Shift + Esc to open Task Manager on your PC.
• Select the unnecessary processes and click the “End task” button to close them.

6. Disable Fast Startup.

Windows comes with a default Fast Startup feature designed to lower system boot time. Unfortunately, it ends up consuming quite a lot of battery power, but you can disable it.

• Press Win + R to open “Run.”
• Type “control panel” and click “OK.”
• Click on “Hardware and Sound” on the left, then open “Power Options.”
• Click on the “Choose what closing the lid does” option.
• Uncheck the “Turn on fast startup” option.
• If you can’t uncheck it, click on “Change settings that are currently unavailable” above, which should allow you to uncheck the Fast Startup option.
