How to Stop Laptop Battery Drain: 10 Pro Tips to Save Your Power

Watching your laptop battery drop from 100% to 10% in just minutes, instead of hours, is a frustrating experience for most users.

However, the good news is that most battery problems are not caused by faulty hardware. Rather, battery issues are caused by background activity, habits, and settings that quietly drain power. In this guide, we will walk you through 10 pro tips to stop battery drain or drop for both Windows and macOS.

Tip 1: Reduce the Laptop’s Screen Brightness

Your Display is the biggest power hog, as it consumes more power than any other component or application. You will notice a significant increase in battery life when you decrease the brightness by 20% or 30%.

What is the Pro Tip?

Make use of adaptive brightness in case your laptop has that feature.

• In Windows: Navigate to Settings, click on System, and go to Display.
• In macOS: Navigate to System Settings, click on Displays, and tap on Automatically adjust brightness.

Tip 2: Turn On the Battery Saver Mode

As we all know, modern operating systems are embedded with smart features such as the low-power mode. In Windows, this feature is referred to as the Battery Saver mode, and in macOS, it is referred to as Low Power mode. This feature automatically restricts background activity, reduces visual effects, and slows processes.

How to Enable It?

• In Windows:

1. Go to Settings, and click on System.
2. Navigate to Power & Battery, then select Battery Saver.

• In macOS:

1. Navigate to System Settings and click on Battery.
2. After that, go to Low Power Mode.

This is one of the simplest ways to prevent unnecessary battery drain without any manual tweaking.

Tip 3: Remove Background Applications Not in Use

Many applications like cloud sync tools, chat apps, browser helpers, and updaters silently run in the background even when you close Windows. They are the common culprits.

How to Check What’s Draining Power?

• In Windows: Go to Settings, click on Battery, and tap Battery Usage.
• In macOS: Navigate to Activity Monitor, and click on Energy.

If any application is consuming power, then quit it completely, turn off background permissions, and replace it with another alternative.

Tip 4: Turn Off Startup Programs You Do Not Require

Every application that launches at startup reduces battery from the very moment you turn on your laptop.

How to Fix It?

• In Windows: Navigate to Task Manager and click on Startup apps.
• In macOS: Navigate to System Settings, go to General, and click on Login Items.

Turn off or disable anything that is not essential, such as old utilities that you forgot to exit, auto-launch clients, and unused cloud sync apps.

Tip 5: Leverage Power-Efficient Browser Settings

Browsers are one of the most well-known battery drainers, specifically Chrome-based browsers with many tabs.

Smart Browser Habits

• Close the tabs that are not in use because every tab uses RAM and CPU.
• Remove unnecessary Chrome extensions.
• Turn on Energy Saver or Efficiency Mode in the browser settings.
• Prefer lighter browsers such as Microsoft Edge on Windows or Safari on macOS.

Tip 6: Disable Keyboard Backlight When Not Required

Though keyboard backlighting looks nice, it requires a lot of power. In case you are in an environment with good lighting, turn off or lower the brightness.

Most of the laptops and operating systems allow this feature through function keys. While in macOS, you must navigate to System Settings, click on Keyboard, and choose Adjust brightness in low light. 

Tip 7: Ensure Your Laptop Stays Cool

Heat is one of the obvious reasons behind battery drain. When your laptop overheats, the fans spin faster, the CPU throttles, and the battery drains faster.

Moreover, you can avoid overheating of laptops by using your laptop on flat surfaces, making use of a cooling pad, cleaning vents daily, and preventing heavy workloads. Hence, cool laptops are the most efficient ones. 

Tip 8: Manage Wi-Fi, External Devices, and Bluetooth

Wireless devices constantly look for connections, and this leads to power consumption. Ensure to disable Bluetooth when not in use, turn off Wi-Fi if you are working offline, and turn off external USB devices like HDDs.

Tip 9: Keep Your Operating System Updated

Software that is outdated consists of bugs that can cause excessive battery drain. Moreover, operating system updates include battery efficiency improvements, better hardware performance, and battery optimization fixes. Update your OS regularly:

• In Windows: Navigate to Settings and click on Windows Update.
• In macOS: Go to System Settings, open General, and click on Software Update.

Tip 10: Check Battery Health

In case your laptop is old, the battery itself can be a problem. Check battery health:

• In Windows: Create a battery report by using powercfg /batteryreport.
• In macOS: Navigate to System Settings, click on Battery, and then go to Battery Health.

Implement healthy charging habits, like avoiding keeping your laptop plugged in all day and not letting the charge go down to 0%. Hence, laptop battery drain is not any mystery, instead it is the result of fixable problems adding up. By adjusting the brightness, optimizing settings, and managing background applications you can extend your laptop’s battery life by hours.
