How do the MacBook versions compare in terms of battery life?

The MacBook line has been a staple of Apple's computer lineup for over a decade, and each new version has brought improvements in performance and battery life. Generally speaking, newer MacBook versions tend to have longer battery life than older ones. Here's a comparison of the battery life for some of the recent MacBook models:

• MacBook Air (M1, 2020): Up to 18 hours
• MacBook Pro 13-inch (M1, 2020): Up to 17 hours
• MacBook Pro 16-inch (2019): Up to 11 hours
• MacBook Air (2020): Up to 12 hours
• MacBook Pro 13-inch (2020): Up to 10 hours

It's important to note that battery life can vary depending on usage, and these estimates are based on Apple's standard tests. Factors like screen brightness, running multiple apps, and using power-hungry applications can all affect battery life. Additionally, battery life tends to degrade over time with regular use.
