In truth, even the most durable laptop batteries ultimately fail. It is also important to remember that unless you pay close attention to some essential factors, the battery in your Mac laptop or PC won’t ever last as long as advertised by the manufacturer.  

The good news is that once you discover which specific settings to change, none of this takes much effort to figure out. As such, this article will guide you through the best and easiest ways to maximize the life of your laptop’s battery.

How to increase the battery life of your Mac

Use the Windows Performance Management Tool

The Windows performance management tool is the first thing to consider when seeking ways to improve your laptop’s battery life. This tool is a slider in Windows 10 that can be accessed via the task bar’s battery icon. It may be found in Settings > System > Power & Battery > Power Mode in Windows 11. It strives to organize every setting that impacts battery life into a few simple categories.

Which settings the battery slider impacts depends on who built your PC. But generally speaking, remember these suggestions:

  • People willing to sacrifice battery life in exchange for speed and responsiveness should use the Best Performance mode. Windows won’t prevent background apps from using a lot of power in this mode.
  • The Better Performance (or Recommended) mode favors power above efficiency, but it restricts resources for background apps.
  • Compared to the default settings on earlier versions of Windows, the Better Battery mode provides longer battery life.
  • The Battery Saver mode, a slider option that only appears when your computer is disconnected, lowers the screen brightness by 30%, pauses Windows Update downloads, halts Mail app syncing, and suspends the majority of background apps.

Use Battery Settings on macOS for Mac Laptops

Modern Mac laptops with the most recent versions of macOS feature a wide range of power and battery settings that you can adjust. Open the System Preferences application on macOS Monterey and select Battery.

Make sure “Enable Power Nap when on battery power” is unchecked and “Slightly dim the display while on battery power” is checked. (When Power Nap is turned on and your MacBook is asleep, it will occasionally wake up to search for updates. Until you decide to wake up your MacBook, disabling it keeps it entirely dormant.) If “Slightly dim the display when on battery power” is enabled on newer MacBook Pro laptops, the display brightness resets to 75% when the device is disconnected from power.

You might have access to extra settings in the Energy Saver preferences pane, depending on the MacBook you have and the version of macOS you are running. A couple of these are “Optimized battery charging” and “Optimize video streaming while on battery,” which disable HDR video playback. Similar to the previously mentioned Windows performance management tool, certain Macs also include an Energy Mode setting. The following choices are available if Energy Mode is selected in the Battery section of system preferences:

  • Low Power: Use less energy to prolong battery life.
  • Automatic: Set your Mac to operate at its optimal performance level.
  • High Power: Use more energy to perform well under prolonged workloads

Shut down Energy-consuming Apps that are not in Use

The battery life on your machine will deplete more quickly if you have several programs and processes running at once, even though you probably aren’t utilizing all of them right then. The Settings app in Windows is the place to start looking for energy-guzzling programs.

For a list of the most power-hungry apps, enter “See which apps are affecting your battery life” into the search bar for Windows 10. This list is accessible in Windows 11 under Battery Usage in the Power & Battery settings pane. Make sure to shut down any infrequently used apps if you notice them using a lot of power. These are usually programs like Adobe Reader or Spotify that you’ve opened in the background but completely forgotten about.

Be Careful of Airflow

Thanks to advancements in software and firmware as well as battery technology advancements, the majority of laptops today come with lithium-polymer batteries that require significantly less maintenance than batteries from ten years ago. The battery no longer needs to be fully discharged regularly to calibrate it, nor do you need to be concerned that doing so would harm your laptop.

However, heat must be avoided because it will speed up a battery’s expiration. Physically blocking the ventilation ports is the major source of issues. One issue is dust accumulation, which you may fix by cleaning the laptop’s fan and vents (occasionally, blow some of the dust out using a can of compressed air.) However, placing the laptop on a pillow or blanket might restrict the ventilation fan and trap heat from the system, making this a more common problem. To prevent this, only use your laptop on flat, rigid surfaces like a desk or table that won’t flex and obstruct airflow or cooling.

Summarily, there are many different things you can do to give your laptop’s battery a shot at a longer life. A good place to start is to heed the tips and instructions we have provided in this article. Remember to share this article with your loved ones who will also benefit immensely from it.
