Battery calibration recommended by Apple, why no utility?

Like virtually all mobile computer manufacturers, Apple recommends that users calibrate their laptop batteries every few months, as Scott pointed out a couple of years ago. Unlike many manufacturers, however, Apple does not include a utility to automatically perform a calibration. Given Apple’s uncanny ability to form things user-friendly, that seems like a bit of a glaring oversight.

What are the benefits of calibration? Primarily the goal is to ensure that the microprocessor in your battery provides an accurate estimate of how much duration you have left on the battery. by date it can lose track of just how much juice your battery has in it,

and calibration gives it a very accurate reading on the battery’s health.

Older battery technologies plus benefited from a process called conditioning, which was typically performed the same way as a current battery’s calibration process. In a nutshell, you fully charge the battery, fully discharge it, soon after fully charge it again. It’s unclear whether contemporary lithium batteries gain anything in an actual capacity perspective from that process, or whether it is simply a calibration of the microprocessor for the purpose of providing accurate instance estimates.
