Mac Battery Tips: From Obvious to Extreme
While the International Earth Day is over, saving energy for whatever reasons is on everybody’s mind, though the agenda may vary from greater environmental good to saving money on your utility bills. If you are a laptop user who is constantly on the go, you probably want to make sure your device’s battery lasts and lasts and lasts for as long as possible, preferably forever.
There’s a variety of methods to extend your battery run-time from relatively common to pretty extreme ones, so lets check them out.
To begin with, your battery needs to be in good shape and calibrated. The calibration process will allow your Mac to correctly estimate how much charge is remaining and when the charge will be used up completely. The calibration process should be done during the first days of Mac use and Apple recommends that you recalibrate the battery every month. Though from our experience recalibration once every 3-4 months is also acceptable.
Selecting Your Energy Preference
Your Mac System Preference has the Energy preference pane which gives you options for managing your device’s energy use. It is probably the most obvious place to start if you need to extend your battery life. Some of the things you can do, include:
*Putting your hard drive to sleep when not in use.
*Turning off back lighting for Mac keyboard. This may come in handy in low light conditions, however if your conditions are generally fine, turning it off is a good way to conserve some battery power.
Switching off unused devices and services.
There’s an assumption that you save more energy once you’ve switched off all your peripherals and charges that are not in use. However, simply disconnecting them is sufficient as it will bring the power draw to zero.
In addition, try turning off some of Mac built-in service, like AirPort or Bluetooth. You can also save power by turning the Wi-Fi off. Both Bluetooth and Wi-Fi can be disabled in System Preferences.
These may work too!
If you are up for a bit of experimenting, you may want to try these less conventional tips.
*Mute the sound
When you switch off your Mac’s built-in speakers, the battery stops being used to generate all of the default sounds associated with various events. You can do so by hitting the Mute button or via the Sound Preference pane.
*Check your email less.
Easier said than done, but turning off you mail auto-checking for new emails may make the difference, since your network connection (which uses a lot of battery power, especially if it’s Wi-Fi) won’t be used and your hard drive won’t be spun.
*Get rid of background notifications
Some apps have a background utility that is on all the time to check for updates. These mini-apps use your Mac’s memory, CPU and network. To turn them off you will need to check individual apps to see if such option exists, since there’s no central way to do it.
*White on black display.
If you want to try something quite extreme, but effectiveб set your desktop wallpaper to solid white via Desktop and Screen Saver preferences pane in System Preferences. This will invert the display colours making all text white and the white background black. If this sounds a bit too drastic to you, just turn down the display brightness.
I am sure, there are many other ways to preserve the battery power. Do share which ones work for you!
