Windows 7 Improves Battery Life
Bookmark and Share

Posted: October 29th, 2009

Are you a frequent flier or just enjoy watching movies on your laptops? You may want to consider the upgrade to Windows 7. With the optimized power savings, a typical laptop can run for more than an hour longer.

"Microsoft and Intel engineers were able to reduce power usage of a Windows 7 laptop nearly 20 percent over an identical laptop running Windows Vista SP2," wrote Joakim Liallias in a blog post earlier this week.

This can mean up to a 1.4-hour increase in your laptop battery life. That's enough to get through the credits, and even get into the special features.

Of course, other methods are still welcome. Here are some laptop battery tips that you may find helpful:

  • Dimming your display: Without question, the fastest way to drain your battery life is leaving the brightness high. Turning the display down as far as you can is a great way to conserve battery power. You can even turn the brightness down all the way if the laptop sits idle for a minute or two.
  • Removing any devices you aren't using: Even when you're not using them, devices like a USB mouse or memory card reader use your battery to function. The battery drain varies based on device, but it can add up.
  • Disabling graphical features: Fancy features like Aero in Windows or the visualizations of your favorite music player use battery power. Disable these if you need to conserve power.
  • Closing applications you aren't using: If you have programs running that you aren't using, go ahead and shut them down. Turning off apps like MSN Messenger, Google Desktop, Bluetooth, WiFi, and other widgets will help.
  • If you're going on a trip, be prepared: Prior to getting on the plane, spend 5 to 10 minutes getting your laptop setup. Once finished, hibernate the laptop before unplugging the power supply.
  • Invest in some noise-canceling earbuds/headphones: The louder the volume, the more battery power you use up. Getting a pair of noise-canceling headphones can help you keep the volume at nominal levels - and protect your hearing as well.
  • Have an extra laptop battery: For long trips, no optimization to your power settings is going to be better than simply having an extra battery to swap out. And, if you can an extended one, even better!
