How to Make a Laptop Battery Last Longer

A laptop’s battery life is one of the most critical factors for users who rely on their devices for work, entertainment, or communication. With advancements in technology, laptop batteries have become more efficient and longer-lasting. However, there are still steps you can take to ensure that your laptop battery lasts even longer. This guide will provide you with practical tips and strategies to extend the lifespan of your laptop battery.

Adjust Power Settings

One of the easiest ways to prolong your laptop’s battery life is by adjusting its power settings. Most operating systems offer power-saving options, which you can configure to maximize battery life. Here are some steps you can take:

Windows: Open the Control Panel, select “Power Options,” and choose a power-saving plan, such as “Power Saver” or “Balanced.” You can also customize the settings according to your preferences.

macOS: Go to “System Preferences,” click on “Energy Saver,” and adjust the settings for both “Battery” and “Power Adapter” modes.
Dim the Screen

The display is one of the most significant power-consuming components of your laptop. Lowering the screen brightness can help extend battery life.

Use the function keys on your keyboard or adjust the settings in your operating system to dim your screen to a comfortable level.

Turn Off Wi-Fi and Bluetooth When Not in Use

Wireless connectivity features, such as Wi-Fi and Bluetooth, consume power even when not in active use. Turning off these features when they’re not needed can save battery power. Most laptops have shortcut keys to enable and disable Wi-Fi and Bluetooth, or you can do so through your operating system’s settings.

Disable Unused Devices and Ports

Certain devices and ports, such as USB peripherals, optical drives, and external graphics cards, consume power when connected to your laptop.

Disconnect or disable these devices when they are not in use to conserve battery life. You can manage these settings through your laptop’s BIOS or your operating system’s device manager.

Close Unnecessary Applications and Processes

Running multiple applications and processes simultaneously can strain your laptop’s battery. Close any unnecessary programs and processes to reduce power consumption. In Windows, you can use the Task Manager to monitor and end processes, while macOS users can utilize the Activity Monitor.

Optimize Your Browser

Web browsers can consume a significant amount of power, especially when loading media-rich websites or running multiple tabs. Optimize your browser by:

Closing unused tabs or using a tab suspender extension to reduce memory usage.

Disabling auto-playing videos and animations.

Using an ad-blocker to prevent resource-intensive ads from loading.

Keep Your Laptop Cool

Excessive heat can negatively impact your laptop’s battery life. Ensure proper ventilation and avoid using your laptop on soft surfaces, such as beds or couches, which can block airflow. If necessary, invest in a cooling pad to help dissipate heat.

Adjust Your Laptop’s Performance Settings

Some laptops allow users to adjust performance settings, such as CPU speed or graphics quality, to conserve battery life. Lowering these settings can help extend your battery’s lifespan, but it may also reduce your laptop’s performance. Adjust these settings through your laptop’s BIOS or your operating system’s power management settings.

Regularly Update Your Operating System and Software

Software updates often include optimizations and bug fixes that can improve your laptop’s battery life. Regularly update your operating system and applications to ensure that you are taking advantage of these improvements.

Battery Maintenance and Care

Proper battery care and maintenance can help extend its lifespan. Some tips for maintaining your laptop’s battery include:

Avoiding extreme temperatures: High temperatures can degrade your battery’s performance, while cold temperatures can temporarily reduce its capacity. Store and use your laptop in a temperature-controlled environment, ideally between 50°F and 95°F (10°C and 35°C).

Regularly calibrate your battery: Over time, the battery meter in your laptop may become inaccurate, leading to improper charging and discharging. Calibrate your battery every few months by fully charging, discharging, and then recharging it.

Don’t keep your laptop plugged in all the time: While modern laptop batteries are designed to handle continuous charging, it’s still a good practice to let your battery discharge periodically. Aim to keep your battery level between 20% and 80% to promote its overall health.

Replace an old or damaged battery: If your laptop battery is more than two years old or shows signs of damage, such as swelling, consider replacing it with a new one to maintain optimal performance.

Use Power-Saving Hardware and Accessories

Invest in power-saving hardware and accessories to extend your laptop’s battery life. Some examples include:

Solid-state drives (SSDs): SSDs consume less power than traditional hard disk drives (HDDs) and can help prolong your laptop’s battery life.

Upgrading to an SSD can also improve your laptop’s overall performance.

Energy-efficient external peripherals: When purchasing external devices, such as mice or keyboards, look for energy-efficient models that consume less power.

Portable laptop chargers: External battery packs or portable laptop chargers can provide additional power for your laptop when you’re on the go, extending its battery life.

Use Power-Saving Software and Tools

There are several software and tools available that can help you optimize your laptop’s battery life. These programs monitor your laptop’s power consumption and suggest adjustments to improve battery performance. Some popular options include BatteryCare for Windows and coconutBattery for macOS.

Opt for Power-Efficient Applications

Some applications are more power-hungry than others. When possible, choose power-efficient alternatives. For example, consider using lightweight text editors instead of feature-heavy word processors or switching to a power-friendly web browser like Microsoft Edge or Mozilla Firefox.

Disable Automatic Updates and Syncing

Automatic updates and syncing can consume a considerable amount of power in the background. While it’s crucial to keep your software up-to-date, consider disabling automatic updates and syncing when running on battery power. You can then manually update and sync when connected to a power source.

Hibernate Instead of Using Sleep Mode

When not using your laptop, opt for hibernation mode instead of sleep mode. Hibernate mode saves your current session to your hard drive and powers off your laptop, using no battery power. Sleep mode, on the other hand, uses minimal battery power to maintain your current session in your laptop’s memory. Although sleep mode allows for quicker startup, hibernation mode conserves more battery power.


Extending your laptop’s battery life requires a combination of hardware and software optimization, as well as proper battery care and maintenance. By implementing the tips and strategies outlined in this guide, you can significantly increase the lifespan of your laptop battery and enjoy a more convenient and efficient computing experience.
