Recalibrating the battery a few times a year will allow the battery charge indicator to provide a more accurate reading. A battery's life can be measured in two ways; by its overall useful lifetime and by the length of time it can run between charges. Battery lifetime is something you generally can't change, at least not drastically. You can extend a battery's lifetime by not overcharging it, and by not recharging it when it doesn't really need to be recharged. Beyond that, a battery's lifetime is pretty much determined by Apple when it selects a particular battery for a particular Mac model.
Although you can't do much to lengthen a battery's lifetime, you can greatly affect its runtime by how you use your Mac.
This guide has tips for eking out that last bit of power between charges. The Energy Saver preference pane is where you set up how and when your Mac will sleep. For desktop users, this preference pane is important but not overly critical. If your Mac portable has a platter-based hard drive rather than an SSD , you can increase battery performance by setting the Energy Saver preference pane to spin down the drive when it's not in use. The problem with simply selecting the option to spin down the drive is that you have no control over how long your Mac will wait before the spin down occurs.
8 tips for improving battery life on your MacBook
No matter how you use your Mac, the drive will go into power saving mode after 10 minutes of inactivity. Ten minutes is a lot of wasted battery life. I'd rather see a shorter time, such as 5 minutes, or 7 at the most. Luckily, you can use Terminal to change the disk sleep time, that is, the amount of idle time that has to occur before the drive spins down.
Each mode offers uniquely different ways of sleeping, and some of them use more battery power than others. You won't find any controls for the sleep modes in the System Preferences, but you can gain control over the various sleep modes by using Terminal.
The SMC System Management Controller takes care of quite a few core functions of your portable Mac, including managing the battery, controlling charging, and displaying run-time information for the battery. Since the SMC is a key component to managing your Mac's battery performance, it can be the cause for some common battery issues, such as failing to charge, not charging fully, or displaying the incorrect amount of remaining charge or remaining time.
