One of the key selling points of MacBooks is their excellent battery life. However, even the most powerful battery degrades over time, and everyday usage habits can cause it to drain faster than expected. Thankfully, there are several practical steps you can take to extend the battery life of your MacBook and ensure it lasts as long as possible on a single charge. In this article, we will dive into 10 effective strategies to maximize your MacBook’s battery life, along with detailed tips and tricks.
Can I Extend My MacBook’s Battery life?
Yes, you can extend your MacBook’s battery life by following simple steps. Lower the screen brightness, use Low Power Mode, and close unused apps running in the background. Turning off Wi-Fi and Bluetooth when not needed also helps conserve battery. Adjust the keyboard backlight, disable unnecessary features like dynamic wallpapers, and keep your macOS and apps up to date for optimal performance. Additionally, avoid exposing your MacBook to extreme temperatures and use the proper charger. By adopting these habits, you can maximize your MacBook's battery efficiency and prolong its overall lifespan.
10 Tips to Improve Your MacBook’s Battery Life
1. Adjust Screen Brightness
The brightness of your screen is one of the biggest factors affecting battery life. Keeping the display at full brightness all the time can quickly drain your battery. Reducing the brightness to a comfortable level can significantly conserve energy.
How to adjust: Go to System Settings > Displays and manually reduce the brightness. You can also enable "Automatically adjust brightness" so the MacBook adjusts based on ambient lighting conditions. This ensures that the display is not unnecessarily bright in darker environments.
2. Enable Battery Saver Mode
MacBooks come with a built-in feature called Low Power Mode (introduced with macOS Monterey) that helps reduce energy consumption when your battery is running low. This feature reduces screen brightness, lowers the system’s processing power, and stops background tasks that consume significant power.
How to enable: Go to System Settings > Battery and toggle on Low Power Mode. You can also choose to enable this mode when your battery drops below a specific percentage.
3. Close Unnecessary Apps and Background Processes
Running multiple apps or background processes can strain your MacBook's resources, causing the battery to drain faster. Close apps that you're not actively using and ensure that you’re not running too many tabs in your browser.
How to monitor apps: Use the Activity Monitor to see which apps and processes are using the most power. Go to Applications > Utilities > Activity Monitor, and look under the Energy tab to close unnecessary applications.
4. Turn Off Wi-Fi and Bluetooth When Not in Use
When your Wi-Fi and Bluetooth are active, even if you're not using them, they continuously search for networks and devices, draining your battery.
How to turn off: You can disable Wi-Fi from the menu bar by clicking the Wi-Fi icon and selecting Turn Wi-Fi Off. Similarly, turn off Bluetooth by clicking the Bluetooth icon in the menu bar and selecting Turn Bluetooth Off when you don’t need to connect to any devices.
5. Manage Background App Refresh
Some apps continue to refresh and pull data in the background, which can consume both battery and bandwidth. Disabling background app refresh for apps you don't need can improve your MacBook’s battery life.
How to disable: Go to System Settings > General > Background App Refresh, and toggle off apps that don’t require background data.
6. Optimize Safari Usage
The brightness of your screen is one of the biggest factors affecting battery life. Keeping the display at full brightness all the time can quickly drain your battery. Reducing the brightness to a comfortable level can significantly conserve energy.
Pro tip: If you often have many tabs open, consider closing unused ones or using a browser extension that automatically suspends inactive tabs to reduce resource consumption.
7. Turn Off Keyboard Backlighting
While it’s helpful in low-light conditions, keeping your MacBook’s keyboard backlight on unnecessarily drains your battery. You can adjust the backlight duration or turn it off completely to save power.
How to adjust: Go to System Settings > Keyboard, and uncheck the option to automatically illuminate the keyboard in low light. You can also use the F5 and F6 keys to manually lower or turn off the backlighting.
8. Keep Your macOS and Apps Updated
Apple regularly releases software updates that include battery optimizations and bug fixes that may improve battery performance. Keeping your macOS and apps up to date ensures that your MacBook runs efficiently.
How to update: Go to System Settings > General > Software Update to check for and install the latest macOS updates. Additionally, ensure your apps are updated through the App Store or respective websites to optimize their performance.
9. Avoid Extreme Temperatures
Extreme temperatures—whether too hot or too cold—can negatively impact your MacBook's battery performance and even cause long-term damage. Apple recommends keeping your MacBook in an environment where the temperature is between 50°F and 95°F (10°C to 35°C).
Pro tip: Avoid leaving your MacBook in direct sunlight, inside a hot car, or in freezing conditions. If you notice your MacBook getting warm during use, make sure it’s placed on a flat surface to allow proper airflow, and avoid using it on soft surfaces like beds or cushions.
10. Calibrate Your Battery and Avoid Full Discharges
Although lithium-ion batteries (like the one in your MacBook) don’t need to be fully discharged often, it's good practice to occasionally allow your battery to go from 100% to nearly empty. This helps recalibrate the battery’s sensor, ensuring more accurate battery level readings.
How to calibrate: About once a month, let your battery drop to around 10% and then charge it back up to 100% without interruption. Avoid keeping your MacBook plugged in all the time, as staying at 100% charge for prolonged periods can shorten battery lifespan.
Bonus Tips
1. Use Energy Saver Preferences:
Under System Settings > Battery, you can configure settings to put your MacBook into sleep mode after a few minutes of inactivity. Adjust the Turn display off after slider to the lowest setting you find comfortable to further conserve power.
2. Disable Dynamic Wallpaper and Transparency Effects:
Eye-catching features like dynamic wallpapers and transparency effects in macOS can look great but consume more power. You can disable these under System Settings > Accessibility > Display by toggling off Reduce Transparency and Reduce Motion.
3. Use the Right Charger:
Always use an Apple-certified charger or a charger with the correct wattage for your MacBook. Using incompatible chargers can affect battery performance and health over time.
Final Thoughts
MacBooks are known for their excellent battery life, but user habits play a significant role in determining how long they can last on a single charge. By adjusting settings, managing apps, and following some simple best practices, you can significantly extend your MacBook’s battery life. Small changes, such as reducing screen brightness, closing unnecessary apps, and enabling Low Power Mode, can make a big difference in how long you can work or play before needing to plug in your MacBook.
