Information in this article applies to Mac laptop computers with macOS Sierra (10.12) and later.
About Battery Calibration
Getting the best run-time out of your Mac's battery starts with having a battery that is in good shape and calibrated. For Mac laptops that have a built-in non-user-replaceable battery (those produced after 2008), calibration is not required because the battery is calibrated at the factory.

Apple maintains that over the course of the battery lifetime, calibration is not necessary. In older Mac laptops with user-replaceable batteries, calibration is necessary for the battery's internal processor to estimate the remaining charge on the battery and predict when the current charge will be used up. If you don't know how to do this, read up on how to calibrate your MacBook, MacBook Pro, or MacBook Air battery.

Your portable Mac has many built-in services, such as AirPlay and Bluetooth, which can be turned off if you're not using them. You can disable Wi-Fi if you're not using this feature.

It may be lit more often than not, even when backlighting isn't needed. Don't use the optical drive if your Mac has one. Spinning up the DVD drive is a huge energy user.

Instead of using the optical drive to watch a movie on a trip, make a local copy of the movie using a DVD ripper. This allows you to store the movie on your laptop and watch it from the hard drive, which, while still an energy hog, is less of one than the optical drive.

They also don't contribute as much heat, so your Mac can save energy in running fans.
Some Other Ideas That Save Battery Power

Set the Mail app (or another mail client) not to check for email regularly. Change the setting so you must check for mail manually. Automatic mail checks use your network connection and spin up your hard drive to write new data if there's new mail.

It's easier said than done, but only check your email when you need to. In macOS Monterey (12.0), you can also turn on low-power mode, similarly to an iPhone. This feature dims your screen and slows your processor to save battery.
