You need it to still perform well in 5 years, your ONLY option is a high end gaming laptop. That’s what I did, and it did indeed last 5 years before dying (like, actually expiring, currently looking for the fault, but it looks terminal). Modern gaming laptops will last a few hours on battery which should be fine for lectures, there are likely plug sockets in the lecture theatres anyway.
You could do what I did and get a cheap windows tablet for mobility purposes and your high powered laptop for everything else. ANYTHING you buy that is thin and light will be woefully underpowered within 2 years, and as a student you won’t have the funds to replace it, so just spend £1500 ish now on a high end gaming laptop (4070, Ryzen 7/ i7) and it will last you.
