How to Extend Your Laptop Battery Life (2025 Guide)

Few things are more frustrating than running out of battery in the middle of an important meeting, lecture, or gaming session. While modern laptops in 2025 come with longer-lasting batteries, how you use and maintain your device has a huge impact on performance.

Here are practical tips to extend your laptop’s battery life and keep it running efficiently for years to come.

1. Adjust Display Brightness

Your screen is one of the biggest power consumers. Reducing brightness to around 50–70% can significantly improve battery life without hurting visibility.

Pro tip: Enable auto-brightness if your laptop supports it.

2. Use Battery Saver Mode

Most laptops have built-in power-saving features:

Windows – Battery Saver Mode
macOS – Low Power Mode
Chromebooks – Energy Saver

These settings automatically adjust performance, background tasks, and screen brightness to conserve energy.

3. Manage Background Apps

Too many apps running in the background drain your battery quickly. Close unused programs like Spotify, Photoshop, or extra browser tabs.

On Windows, check Task Manager (Ctrl + Shift + Esc).
On Mac, use Activity Monitor.

4. Disconnect Unused Devices

External drives, dongles, and even wireless mice can draw extra power. Disconnect peripherals when you don’t need them.

5. Update Software & Drivers

Laptop manufacturers often release updates to improve battery performance. Keeping your Windows, macOS, or drivers updated ensures your system runs efficiently.

6. Control Charging Habits

Don’t keep your laptop plugged in 24/7—this can shorten battery lifespan.
Follow the 40–80 rule: ideally keep your battery between 40% and 80%.
If you use your laptop plugged in most of the time, enable battery protection settings (available on many 2025 laptops).

7. Reduce Startup Programs

Unnecessary apps that launch on startup use both CPU and battery. Disable them to save power and speed up boot times.

8. Optimise Power Settings

Customise your laptop’s power plan:

Set shorter sleep timers (e.g. screen off after 5 minutes).
Disable keyboard backlight when not needed.
Turn off Bluetooth if you’re not using it.

9. Consider Battery Health Tools

Many modern laptops (Dell, HP, Apple, ASUS) include built-in software to monitor battery health. Use these tools to check charging cycles and adjust settings for long-term battery care.

10. When to Replace Your Battery

Even with the best care, batteries wear out over time. If you notice:

Rapid battery drain
Overheating during charging
Less than 2 hours of runtime

…it may be time to replace the battery.

Final Thoughts

Extending your laptop’s battery life isn’t just about lasting longer between charges—it also helps your device stay healthy for years. By adjusting settings, managing apps, and practising smart charging habits, you’ll get the most out of your laptop.
