How to Drain a MacBook Battery

Unplug the power cable from your MacBook and run the computer from the battery. Plugging in the cable will recharge the battery, so avoid doing this until you have fully drained the battery.
Click the 'Apple' button on your MacBook's desktop and click 'System Preferences.' Click 'Energy Saver.' Select 'Battery' from the 'Settings for' drop-down list. Select 'Better Performance' from the 'Optimization' drop-down list. This will disable many of the MacBook's battery-saving settings.

You can find a full list of gestures in Apple's iPad User Guide. When you have tried this out, tap 'Done' and then double tap to return to the menu.
Tap the 'Speaking Rate' button to change the speed of speech, if you find the default rate too slow or too fast. Swipe up to increase speed or swipe down to decrease it. You can also activate or deactivate other VoiceOver features in this menu, such as Pitch Change, Sound Effects and Languages & Dialects.
Select and double tap the 'Rotor' button. You'll use the rotor to control and change settings as you navigate around your iPad. Tap on an item to select it and then double tap to add or remove it. If you don't want to make any changes at this stage, leave the default list as it is.
Press the 'Home' button to return to the Home screen. Open a Web page or an email to test the Rotor. It works like a dial: Put two fingers on the screen and rotate them to open it.
