Macbooks are very popular in 2011 and one impressive thing about macbooks is their long laptop battery life. And many users still think the life is not long enough. And here, we will have a talk about how to save battery life of macbooks.
One useful tip is to adjust Screen Brightness. At full brightness, the 13-inch MacBook Air’s screen measures an average of 285 lux. At 40-percent brightness, and it’s just 29 lux, but still very viewable. And brightness eats power. Quitting runaway applications can also work. Disabling your notebook’s wireless radios is one surefire way to eke out more juice. While turning off Wi-Fi may not be practical in every situation, especially if you need to access the Internet often—it will give you more endurance if you’re using your laptop to watch a movie on an airplane.
The next one is to turn off backlit keyboard.While it’s a great feature, the backlit keyboard on Macs can shave precious minutes off your runtime. You can hit the F5 key repeatedly until the on-screen icon shows no bars lit. Turn off Time Machine. Time Machine makes it very easy to back up all the data on your Mac, but copying that data to another drive consumes system resources. Fortunately, you can turn off Time Machine while your laptop is running on battery power.
Eject optical disks if you’re not using them/disconnect unused peripherals. Even when not in use, whenever you have an optical disk in your notebook, the system will occasionally spin up the drive to check the disk. While this isn’t an issue for MacBook Airs, which lack optical drives, you can save battery life by disconnecting any peripherals, such as external hard drives and mice. These devices don’t draw a ton of power, but every little bit helps. Enable private browsing. Believe it or not, private browsing will let you squeeze out a bit more laptop batteries life, because the browser is no longer accessing the hard drive to cache pages and images. Of course, Safari won’t remember your search history or autofill forms, so you have to balance its convenience with the potential battery savings.
Turn off Spotlight indexing. Apple’s Spotlight, which instantly returns search results of everything on your hard drive, is very useful. But the way it works consumes CPU resources. You can prevent Spotlight from searching your drive. If your macbook is pro series, choose Automatic Graphic Switching but be attention, it is for macbook pros only. MacBook Pros have both integrated and discrete GPUs and can switch between the two seamlessly, so you can get better macbook battery life or increased performance, depending on the task. However, the discrete GPU can seriously cut into battery life.
