For every MacBook users, especially those who are traveling, long battery life and the health of the battery is very important position. The tips below will help ensure you get the most out of your MacBook battery over its lifetime.
1. Turn off AirPort Wireless (Wifi) if not needed
If you do not need internet and if there is no WiFi networks within range, turn off AirPort far will save your computer’s battery. It is also wise to use more wireless Ethernet cable if that option exists.
2. Turn off Bluetooth when not in use
Again, if there is no need for a Bluetooth device, the best thing to do is to turn off the Bluetooth feature of your MacBook.
3. Minimize the use of the iSight camera
ISight camera uses a lot of battery power. Making its use to a minimum if trying to prolong battery life.
4. Remember to eject the disc from the DVD drive
Motor in optical drive is required for rotating DVD and CD can use a lot of power. Thus, eject your disc to maximize battery life. If you insist on watching a DVD, say on a long trip, rip them to your hard drive first instead.
5. Reduce Screen Brightness
Turn the screen brightness to a comfortable level you can work, and your battery life will significantly increase. Bright screen, the shorter the battery life.
6. Turn on / off the backlit keyboard
Similar to the brightness of the screen, keep the backlit keyboard (if you have one) at the lowest point or off will save a lot of battery.
7. Turn down the volume or use headphones
Loud volume on your MacBook requires more energy. It is more energy efficient plug in the headphones not if you like to listen to loud audio / music.
8. Run fewer applications at the same time / turn off unneeded applications
By running fewer applications simultaneously, or install the RAM, you reduce your risk of having the unused portion of your memory called to tasks, thus saving battery.
Not enough just pressed the red button (exit) on mac, because it is not put out an application (program terminated) but just as hide, try to pull out the application by right click on Programs wanted released -> Quit or press Command + Q
There are applications that have been issued but still shows the progress? You can forcibly eject the application, if the application is running, but at the dock no such applications whose name you can do the Force Quit Applications way by pressing the command Command + Option + Esc simultaneously easy enough right?
9. Do not disable core CPU
For all MacBook with more than one CPU core, core disabling NOT wise. Your MacBook chip is designed to run efficiently with multiple cores enabled. Disabling one does not only require less power, but also generate more heat. Some users have reported losing up to 40 minutes of battery life by turning off the core!
10. Calibrating the battery every few months
Finally, if your battery is showing signs of a shorter run times, you might want to try to calibrate the battery (every few months). To calibrate the battery, follow these instructions:
a) Fully charge your MacBook.
b) Once fully charged, leave it plugged in for at least 2 hours.
c) Disconnect the MagSafe power adapter and use your computer until you get the battery level warning message.
d) Ignore the message and continue running your notebook.
e) Finally, the machine will go to sleep.
f) Do not install. Instead, let sleeping at least 5 hours.
g) After the time has elapsed, plug it back in, and let it fill up.
h) Once fully charged, the battery has been calibrated correctly.
