Before we dive into fixes, it's essential to understand the most common causes of battery drain. Here are some likely culprits:
Background apps and processes: Some apps, especially those running in the background, consume more power than others.
High screen brightness: A bright screen uses significantly more power, particularly on older MacBooks.
Outdated macOS: New macOS versions often come with optimizations for better battery life. Failing to update your Mac could result in inefficient power usage.
Hardware issues: A worn-out or faulty battery will naturally drain quicker and may require replacement.
Resource-heavy applications: Running applications like video editing software or games can drastically reduce battery life.
Now that we know what might be draining your battery, let's go through actionable troubleshooting steps to improve its performance.
The first step in troubleshooting battery issues is determining the overall health of your Mac's battery. If your battery is old or degraded, it may not hold a charge for as long as it once did.
How to check battery health:
Hold down the Option key and click the Apple logo in the top-left corner.
Select System Information.
Under the Hardware section, click on Power.
Look for the Battery Information section and check the Condition field. If it says anything other than Normal, it might be time to replace the battery.
Example:
Normal: Battery is functioning properly.
Replace Soon/Replace Now: Battery health has declined and may need replacement.
Screenshot suggestion:
Show the Battery Information section in System Information, highlighting the Condition field.
Insight: If your battery health is poor, it will directly impact performance. Consider visiting an Apple Store or authorized repair center for a battery replacement.
Your screen is one of the most power-hungry components of your Mac. Reducing screen brightness can significantly increase battery life.
How to adjust screen brightness:
Press the F1 (decrease brightness) or F2 (increase brightness) keys on your keyboard.
Alternatively, go to System Preferences > Displays, and use the slider to adjust the brightness.
Insight: Lowering the brightness to a comfortable but dimmer level can lead to noticeable battery savings, especially if you are using your MacBook unplugged for long hours.
Background apps can eat up a lot of your battery without you even realizing it. Some apps consume resources like CPU and RAM, which, in turn, drains the battery.
How to identify and close resource-hungry apps:
Open Activity Monitor (Applications > Utilities).
Look at the Energy tab to identify apps that are using the most power.
Close any apps that are consuming unnecessary power, especially ones that are not actively being used.
Example error message:
If you see a process consuming 100% CPU, that could lead to a significant battery drain, especially if left unchecked.
Screenshot suggestion:

Insight: Apps like web browsers (with many tabs open) and media players often consume significant energy. It’s a good practice to close apps you’re not using to save power.
macOS has several built-in features designed to extend battery life. If you want to make sure your Mac is running efficiently, enable Battery Saving Mode and other energy-saving features.
How to enable Battery Saver:
Click on the Apple logo and go to System Preferences.
Select Energy Saver or Battery (depending on macOS version).
Enable Battery Health Management and check the box for Low Power Mode if available.
Insight: Low Power Mode limits background activities, optimizes display brightness, and slows down some processes to conserve battery.
Sometimes battery issues are related to bugs or inefficiencies that can be fixed with software updates. Keeping your macOS and apps up to date ensures that you’re running the latest optimizations for better battery performance.
How to update macOS:
Go to System Preferences > Software Update.
If an update is available, click Update Now and follow the on-screen instructions.
Insight: macOS updates often include fixes for bugs that may affect battery life. Additionally, updating apps can prevent them from using excess resources unnecessarily.
If you're not using Wi-Fi or Bluetooth, turning them off can save battery life. These features constantly search for available networks or devices, which can use extra power.
Steps to turn off Wi-Fi and Bluetooth:
Click the Wi-Fi icon in the menu bar and select Turn Wi-Fi Off.
Click the Bluetooth icon and select Turn Bluetooth Off.
Insight: This is especially useful when you’re working in a location with no available Wi-Fi or Bluetooth devices to connect to.
If you’ve tried all the above steps and your battery issues persist, resetting the NVRAM (Non-Volatile Random Access Memory) and SMC (System Management Controller) can often help with hardware-related issues.
How to reset NVRAM:
Shut down your Mac.
Turn it on and immediately press and hold Option + Command + P + R for about 20 seconds.
Release the keys and let your Mac restart.
How to reset SMC:
Shut down your Mac.
For MacBooks with a T2 chip, press and hold the power button for 10 seconds.
For other MacBooks, press and hold Shift + Control + Option on the left side and the power button for 10 seconds.
Insight: These resets help resolve low-level system and hardware issues, including battery and power management glitches.
This could be due to several factors, including high screen brightness, resource-heavy apps, or background processes. Try closing unnecessary apps, lowering brightness, and using Low Power Mode to extend battery life.
Check the Battery Health section in System Information. If the condition says Replace Soon or Replace Now, it's a sign that the battery needs replacement.
Yes! Apps like video editing software, games, and web browsers with multiple tabs open can drain your battery. Always check Activity Monitor to see which apps are consuming the most power.
Enable Low Power Mode, reduce screen brightness, close unnecessary apps, and turn off Wi-Fi and Bluetooth if you don’t need them.
Battery life problems on your Mac can stem from a variety of issues, but with the right steps, they can usually be resolved. Whether it’s adjusting your power settings, updating software, or checking battery health, these tips will help you maximize your Mac’s battery performance and ensure it lasts throughout your busy day.
If none of these fixes work, and your battery continues to drain quickly, it may be time to visit an Apple Store or authorized service center for further diagnosis and possibly a battery replacement.
