In this article, you'll learn five effective tips to extend your laptop’s battery life, plus a list of the most battery-efficient laptops worth checking out.
💡 Tip 1: Adjust Display & Brightness Settings
Your display is one of the biggest power consumers. Here's how to take control:
- Lower screen brightness to the minimum comfortable level
- Turn off keyboard backlighting when not needed
- Reduce screen timeout so it turns off when idle
- Enable Adaptive Brightness (if available)
🔧 How to do it on Windows:
Go to Settings →
System → Display
🔧 On macOS:
Go to
System Settings → Displays
Every percent of brightness you reduce saves battery!
💻 Tip 2: Close Background Apps & Disable Startup Programs
Many apps run silently in the background even when you’re not using them—and they silently eat up battery.
What to do:
- On Windows, open Task Manager → Startup tab and disable non-essential apps
- On macOS, go to System Settings → Users & Groups → Login Items
Also, regularly close apps like Chrome, Spotify, Teams, or Dropbox when you’re not actively using them.
⚡ Tip 3: Use Battery Saver or Power Mode
All modern laptops include built-in battery optimization modes.
On Windows:
- Go to Settings → System → Power & battery
- Enable Battery Saver or Power Efficiency mode
On macOS:
- Go to System Settings → Battery
- Enable Low Power Mode
These modes automatically reduce performance, background activity, and screen brightness boosting your backup instantly.
🔌 Tip 4: Unplug Unused Devices & Turn Off Connectivity
External devices and wireless connectivity draw power even when idle.
What to unplug or disable:
- USB devices like hard drives, phones, and accessories
- External monitors
- Bluetooth (if not in use)
- Wi-Fi (when you’re just watching downloaded videos or editing documents offline)
Disabling these features can make a big difference especially on lightweight ultrabooks.
🌡️ Tip 5: Keep It Cool & Updated
Did you know that high temperature drains your battery faster?
- Use your laptop on a hard, flat surface to improve airflow
- Avoid using on beds or cushions that block vents
- Clean out dust from vents and fans periodically
Also, keeping your laptop's BIOS, drivers, and OS updated ensures the battery management system works efficiently.

necessarily. Modern laptops stop charging when the battery is full.
But occasionally unplugging and letting it drain to 40-80% helps
preserve battery health.
Q: How often should I calibrate my laptop battery?
Once
every 2-3 months is enough drain to 0%, then charge to 100% without
interruption.
Q: Do apps running in the background really affect
battery?
Yes! Even minimized apps like browsers, music
players, and syncing tools drain CPU and battery.
