Available in silver, space gray, and gold, the latest MacBook Air features a stunning Retina display with True Tone technology, Touch ID, a backlit Magic Keyboard, and a Force Touch trackpad - all housed in a thin and light iconic wedge design made from 100 percent recycled aluminum.² And with 11-hour battery life, it's a do-it-all notebook that goes all day long.¹. Apple is launching new products every year along with lots of excellent features. Apple Mac book pro and air are the incredible products from Apple, with the long-lasting battery of around more than 6-8 hours. Also, Apple has included some features in the MAC book to increase the battery life even more. The battery in your new MacBook Pro or MacBook Air has a finite life, but with a few steps you can maximize how long it is before you have to replace them — and how many hours of use you get. Your MacBook knows when it’s plugged in and runs accordingly. When using battery power, it dims the screen and uses other components sparingly. If you change this setting to maximize performance, your battery will drain more quickly. Dim the screen to the lowest comfortable level to achieve maximum battery life. MacBooks have some of the best battery life of all laptops: the 13“ MacBook Air is meant to last up to 12 hours but often lasts longer, while even the 15” MacBook Pro should stay running for at least nine hours as long as you aren’t doing anything too strenuous.
This week, Apple released macOS Catalina 10.15.5, rounding out a series of system software updates that has rolled out to various Apple platforms (iOS, iPadOS, watchOS, tvOS) over the course of a week or so.
This version of macOS is primarily focused on a new battery management feature similar to one already introduced in iOS. It helps prolong the life of the device's physical battery by moderating charging based on users' habits.With 'Battery Health Management' in macOS 10.15.5, Apple aims to increase the life of the lithium-ion battery in each MacBook by limiting that laptop's maximum charge level when plugged in based on analysis of your charging patterns and the battery's temperature history. Charging to full unnecessarily can reduce the number of cycles before a lithium-ion battery becomes less reliable.
In a support page on the feature, Apple explains:
Based on the measurements that it collects, battery health management may reduce your battery's maximum charge when in this mode. This happens as needed to ensure that your battery charges to a level that's optimized for your usage—reducing wear on the battery, and slowing its chemical aging.
The company goes on to note that while this can increase the longterm viability of your laptop's battery, it can obviously reduce how much time you can use the laptop between charges. The feature tries to tailor itself to fit how long you tend to be unplugged, but there's some variance there.
To that end, you can turn off the feature in the System Preferences panel in macOS. Also, the device's battery health is now reported in the Energy Saver section of System Preferences.
There are only two other features listed in the macOS 10.15.5 release notes. One is special new controls for calibrating and tuning Apple's Pro Display XDR monitor, and the other is the ability to disable 'automatic prominence' in Group FaceTime calls—that is, to prevent video tiles from changing size based on who is speaking at a given moment.
Beyond that, 10.15.5 is about bug fixes, including one that prevented a T2 chip-equipped machine's internal speakers from appearing as a sound output device, as well as a 'stability issue when transferring large amounts of data to RAID volumes,' among other things.The update is available now to all Macs that are supported by last year's Catalina update. Apple is expected to unveil the successor to macOS Catalina at its virtual developer conference in late June.
