It happens to the best of us. You’re in the middle of an important task or a great movie when the dreaded low battery warning flashes on your screen. While laptop batteries naturally degrade over time, the way we use and care for them can dramatically slow that process down. You don’t have to be tethered to an outlet forever.
By making a few simple adjustments to your habits and settings, you can significantly extend your laptop’s battery life, giving you more freedom and saving you money on a premature replacement. Let’s look at some practical steps you can take right now.
Adjust Your Screen’s Brightness
One of the biggest drains on your battery is the display. Simply turning down your screen brightness can add a surprising amount of time to your battery life. Most laptops have keyboard shortcuts for this, usually involving the “Fn” key and a function key with a sun icon. Dimming it to a level that is still comfortable for your eyes is an instant win. Also, setting your screen to turn off after a short period of inactivity in your power settings helps immensely.
Manage Your Background Applications
Take a moment to check what’s running in the background. Applications like web browsers with many tabs open, streaming services, and other software you aren’t actively using are silently consuming power. Get into the habit of closing programs when you’re finished with them. On Windows, you can check the Task Manager, and on macOS, check Activity Monitor to see which apps are using the most energy.
Optimize Your Power Settings
Both Windows and macOS have built-in power plans that do a lot of the work for you. On Windows, switch to “Power Saver” mode when you’re unplugged. This mode automatically limits background activity and adjusts performance for better efficiency. On a Mac, head to System Settings and select “Low Power Mode” to achieve a similar effect. These settings are a simple switch that makes a big difference.
Be Mindful of Heat and Charging Habits
Heat is a battery’s enemy. Avoid using your laptop on soft surfaces like beds or couches that can block ventilation and cause it to overheat. When it comes to charging, the old advice of fully draining a battery is for older battery types. For modern lithium-ion batteries, it’s better to keep them between 20% and 80% charge when possible. There’s no need to leave it plugged in at 100% all the time.
Extending your laptop’s battery life is mostly about adopting small, mindful habits. By being a little more conscious of your screen brightness, the apps you have open, and your power settings, you can enjoy more cord-free hours and help your battery stay healthy for years to come.
