How to Increase Your Laptop Battery Life

Charging-laptopLaptop batteries have a tendency to die when you least want them to. They often run out of power when you’re as far away from an outlet as can be. However, there are several ways that you can extend the life of your laptop battery so you don’t have to worry about scrambling for a charge. Here’s a look at some of the best battery-saving tricks.

Reduce screen brightness

A bright screen looks good. However, it can take a lot of electricity to keep your screen as bright as you’d like. Keeping your screen bright is actually one of the most energy-intensive functions of a laptop computer. You should reduce your brightness to as low of a level as you can tolerate. You can typically reduce your computer’s brightness through your control panel settings. Many laptops also have keyboard buttons that allow you to set your brightness without opening any menus.

Use power-saving features

As people have become more conscious about the amount of energy that they use, technology companies have been fast to adapt to these needs. Most modern laptops now have energy-saving modes that will exhaust your battery at a much slower rate. Although performance may occasionally suffer when using a power-saving mode, you will most likely not notice the difference unless you’re performing very intense tasks such as gaming or video rendering.

Only use Wi-Fi when necessary

A wireless Internet connection is vital when using a laptop in most situations. However, there are times when you either don’t need to be online or you have no access to a Wi-Fi signal. If you’re not using a wireless Internet connection at the moment, turn your Wi-Fi off. If you keep it on while not connected to the Internet, your laptop will continually search for new network connections, a process that can use a ton of battery power.

Disconnect your peripherals when not in use

USB devices draw a certain amount of power from your computer so they can operate. Although the amount of power used can often be minimal, a slow, steady drain on your energy resources will add up and take time away from your battery life. Once you’re finished using any external device with your computer, unplug it so it stops wasting battery life.

Replace your battery

A laptop battery only lasts for so long. On average, a laptop battery will only work properly for about 400 full charges before its performance deteriorates. This amount of charges should give you a few years of uninhibited use. However, after this period of time, the chemicals in your battery will start to go bad and become less efficient at storing power. You don’t have to keep track of how many times you charge your computer, but if you’re noticing that your laptop simply can’t stay powered for more than a couple hours, it may be time to invest in a new battery.

  1. I had no idea that the battery only last for so long. My daughters laptop is only a few years old, but loses battery life quickly if not plugged in. Good to know!

    Thank you for the great tips!

  2. Great tips! I always seem to lose battery power at the most inopportune times.
