How to Save Your Laptop Battery Life

By Aramenta Waithe

Thanks to new power-saving features and high-capacity batteries, today's laptops run much longer on battery power than notebooks from previous generations. However, few laptops can last all day on battery power when pushed to the limit. For maximum battery life, your laptop may need a little coaxing from you. Avoid usage that quickly drains the battery, and use your laptop in an environment that allows the battery to operate at maximum efficiency.

Step 1

Use an efficient power scheme in Windows to adjust several system settings automatically for maximum battery life. Right-click the battery icon in the notification area, and click "Power Options." Click the "Power Saver" radio button and then close the window.

Step 2

Reduce the brightness of the display. Laptop displays use bright fluorescent or LED backlights for maximum brightness, making the screen one of your laptop's largest draws of battery power. In a low-glare indoor environment, you likely do not need to run the screen at its maximum brightness level.

Step 3

Avoid gaming and watching videos while running your laptop on battery power. These activities generate high battery loads by increasing the usage of your computer's processor and video graphics adapter.

Step 4

Turn your laptop's wireless adapter off if you are not using the Internet. Even if you are not currently browsing the Web, your laptop's wireless adapter remains active, searching for signal and maintaining contact with the wireless access point, causing a slow trickle of battery usage.

Step 5

Use your laptop in a comfortable environment. According to Apple, laptop batteries function best in an environment between 50-95 degrees Fahrenheit. Using your laptop outside of this temperature range can reduce the life of the battery. A very hot usage environment also causes the laptop's fan to remain on, causing an additional draw on battery power.
