Preserve your Battery

Unlike other laptop producers, Apple advices its users of MacBooks not to fully discharge and recharge the battery more than one or two times a week. Some people believe that if they let their battery discharge at every use, they will be able to keep the battery longer, but this is just a myth.  If you want to preserve your battery and to optimize it, you should use it wisely, without completing too many discharge and recharge cycles per year.

Moreover, you should be careful not to leave your laptop plugged in all the time, because the battery may get seriously affected in time. However, there are many people who use their laptops at work and who keep them plugged in, but if you unplug it and use it on battery when you go home, then you have no reason to worry that your battery will have to suffer because of this habit.

Also, take into consideration the following tweaks regarding the System Preference settings, in order to optimize more your MacBook’s battery:

  • In the “Energy Saver” section of the System Preferences, users should select the “Better Battery Life” option when running only on the battery.
  • Disable the Spotlight feature by
  • Go to “Displays” and deselect the “Automatically adjust brightness…” option, which will considerably increase the battery lifetime.
  • Stop using features like Expose, Spaces or Dashboard. If you already are using Dashboard, type “killall Dock” into the Terminal to restart and to be able to close it.
  • Another good tip is to turn off hot corners from the “Screen Saver” or “Expose” preferences.
  • If you don’t own or use a remote control very often, it is a good idea to disable the infrared receiver for the remote control by accessing the “Security” section of System Preferences.
  • Also, stop all sharing services that are not necessary, like Bluetooth or Wi-Fi, especially if you using a cable for your connection.
  • In the “Displays” area, reduce the Brightness level to the minimum you support, because the screen is one of the largest battery consumers.
  • Also, if you don’t absolutely need the backlight from your keyboard you should stop it too. To do this, go to “Keyboard” section and de-select the “Automatically illuminate keyboard in low light” option. Now, if the light is still on, press the F5 until it will totally turned off.
