Apple’s low-cost MacBook is launching soon. Can it trump affordable Windows laptops?

Through longer hours of study, I have to attend lectures for 6-7 hours every day. I often struggle to carry chargers between my assignments and note-taking. Next month, I am considering buying a MacBook and with Apple’s affordable launching soon, will that be fine? As a student, I am constrained by my budget. I am looking for longer battery life and want to use it for as many years as possible. Also, will it perform better than the Windows laptops?
