You won’t need to carry the charger to lectures or work. The battery life is still class-leading, too, regularly exceeding 16 hours of work between charges, including several hours of photo editing in Affinity Photo, having 20 or tabs open in Chrome most of the time, and using Apple Mail, Typora, Evernote and a variety of chat apps and smaller tools. Unless you know your work is very computationally demanding, I would expect the Air to be more than capable for most, despite the lack of a fan for cooling. The laptop stayed cool for three hours of fairly demanding photo manipulation work with large image files while attached to a separate 4K display. It is a fanless machine, making it completely silent in operation.
The M2 makes the MacBook Air a rapid, highly capable machine that will easily handle any general computing requirement and bursts of more demanding things. It is an incremental upgrade from the once-in-a-generation leap made by the M1 in 2020 but is still up to 18% faster, with 35% more powerful graphics. The 2022 MacBook Air is one of the first machines to have Apple’s next-generation M2 chip. The sleek MacBook Air is easy to slip into a bag and light enough to not be burden.
