Your MacBook has an internal processor which is designed to maximize your battery performance and to estimate your battery life. In order to get accurate readings, you need to calibrate your Mac's battery on a regular basis depending on how often you use it. Developing this habit ensures long battery life for your Mac and here are the steps how to calibrate the battery on your MacBook.
1. First, you have to make sure that your MacBook is fully charge. The best way to know this is to plug in your Mac rather than looking at the battery indicator on your screen. A green light on the battery's light indicator and a 100% charge on your screen means it is fully charged.
2. After that, continue plugging your Mac to the AC adapter for two hours. You can also use your computer during this time.
3. Unplug the adapter after two hours without turning your MacBook off. This will transition to battery power smoothly. Continue using your MacBook or let it turned on until the low battery signal appears on your screen.
4. When the low battery warning appears on your screen, save whatever work you're doing in progress and continue using your MacBook until it shuts off. Once it automatically goes to sleep mode, turn your Mac off.
5. Once drained of power, don't charge your Mac until a minimum of 5 hours have passed. After the 5-hour mark, plug it again until fully charged. You have successfully calibrated your MacBook and it will give you accurate battery time estimations.
