How to Save Battery on MacBook: 15 Tips That Work

If your MacBook’s battery drains faster than you’d like, a few settings changes and habits can noticeably extend how long it lasts between charges. This guide walks through the most effective, built-in ways to reduce power consumption—no extra software needed—so you can get more work done away from an outlet.

What You’ll Need

• A MacBook running macOS Ventura or later (steps may vary slightly on older versions)
• Access to System Settings (or System Preferences on older macOS)
• A few minutes to adjust settings

Step-by-Step

1. Check Battery Health – Go to System Settings > Battery. Click the “i” next to Battery Health. If it says “Service Recommended,” your battery may need replacement; otherwise, proceed with the tips below.
2. Enable Low Power Mode – In System Settings > Battery, choose “Low Power Mode” and set it to “Always” or “Only on Battery.” This reduces background activity and screen brightness, significantly extending battery life.
3. Lower Screen Brightness – Use the F1 key (or Control Center) to reduce brightness to the lowest comfortable level. Also, go to System Settings > Displays and turn off “True Tone” if you don’t need it, as it uses extra power.
4. Shorten Screen Sleep Time – In System Settings > Lock Screen, set “Turn display off on battery when inactive” to 5 minutes or less. The less time the screen stays on, the less power it uses.
5. Turn Off Keyboard Backlight – Press the key with the keyboard icon (usually F5) until the backlight is off, or set it to turn off automatically after a few seconds in System Settings > Keyboard.
6. Disable Bluetooth and Wi-Fi When Not Needed – Turn off Bluetooth from Control Center if you’re not using wireless peripherals. For Wi-Fi, you can turn it off too, but only if you don’t need internet; otherwise, skip this step.
7. Close Unused Apps – Quit apps you’re not actively using (Cmd+Q). Apps running in the background—especially browsers with many tabs, video editors, or games—consume significant power.
8. Reduce Browser Power Usage – In Safari, use the “Reader” view for articles and close unused tabs. In Chrome or Firefox, consider installing an extension like “Auto Tab Discard” to suspend inactive tabs.
9. Check Activity Monitor – Open Activity Monitor (in Applications/Utilities) and go to the “Energy” tab. Sort by “Energy Impact” to see which apps use the most power. Quit or force-quit any that are unexpectedly high.
10. Turn Off Background App Refresh – Go to System Settings > General > Login Items & Extensions. Review the list and disable any apps that don’t need to run in the background. Also, in System Settings > Notifications, turn off notifications for apps that don’t need them.
11. Disable Dynamic Wallpaper – Go to System Settings > Wallpaper and choose a static image instead of a dynamic one. Dynamic wallpapers change throughout the day and use extra power.
12. Reduce Motion and Transparency – In System Settings > Accessibility > Display, enable “Reduce Motion” and “Increase Contrast.” These reduce the graphical effects that consume GPU power.
13. Use Dark Mode – If your MacBook has an OLED display (most do not, but newer models might), dark mode can save battery. For LCD displays, the effect is minimal, but it still reduces power used by the backlight.
14. Manage Battery Charging – In System Settings > Battery, click the “i” next to Battery Health and enable “Optimized Battery Charging.” This reduces battery aging, which helps maintain capacity over time.
15. Keep macOS Updated – Go to System Settings > General > Software Update and install any available updates. Apple often includes power efficiency improvements in updates.

Common Mistakes

• Leaving the screen at full brightness – The display is the biggest power consumer. Even a 20% reduction can add 30-60 minutes of battery life.
• Not quitting apps, just closing windows – Many apps (like Mail or Calendar) keep running in the background unless you quit them completely.
• Using Low Power Mode only when battery is low – Enabling it early in the day prevents the battery from draining quickly in the first place.
• Forgetting about external devices – A connected phone, external drive, or even a mouse charging cable draws power from your MacBook.

Tips

• Use the “Battery” menu bar icon (if not visible, go to Control Center and add it) to quickly see which apps are using the most energy.
• If you’re doing light work like writing or browsing, consider using a lightweight text editor instead of a heavy word processor.
• Keep your MacBook in a cool environment. Heat degrades battery health and reduces efficiency.
• If you’re watching videos, use the native player in QuickTime or Safari instead of a web player with DRM, which uses more power.

Troubleshooting

If your battery still drains quickly after following these steps:

• Check for background processes – Open Activity Monitor and look for any process with high “Energy Impact” that you didn’t expect. Sometimes a stuck app can consume 100% CPU.
• Reset the SMC – On Intel Macs, shutting down, then holding Shift+Control+Option on the left side and the power button for 10 seconds can reset the System Management Controller, which manages power. On Apple Silicon Macs, simply restarting usually suffices.
• Check battery health again – If it says “Service Recommended,” your battery may need replacement. Contact Apple Support or visit an Apple Store.
• Try a different user account – Create a new user in System Settings > Users & Groups. If battery life improves there, a login item or setting in your main account is the culprit.

Frequently Asked Questions

1. Does closing apps really save battery? Yes, especially apps that run background tasks like checking email or syncing. Quit apps you’re not using to reduce CPU and network activity.
2. Is it bad to keep my MacBook plugged in all the time? No, modern MacBooks have optimized battery charging that limits charging to 80% until you need it. Keeping it plugged in is fine for the battery’s lifespan.
3. Should I use a third-party battery saver app? Most are unnecessary. macOS has built-in tools that do the job. Third-party apps often run in the background and use extra power themselves.
4. Why does my battery drain even when the MacBook is asleep? Some apps can prevent sleep. Check System Settings > Battery > Options to ensure “Wake for network access” is off, and close apps that might be keeping the system awake.
5. Does dark mode save battery? Only on OLED displays, which most MacBooks don’t have. On LCD screens, the backlight is always on, so dark mode has a negligible effect.
6. How often should I calibrate my battery? Modern lithium-ion batteries don’t require calibration. Just use your MacBook regularly and keep it updated.
