For the price point of entry level M1 Air or Pro, there is nothing that competes on battery life. I'm in South Africa, with spotty electricity. I need a laptop that can sustain work for 4-6h without charge without spending an extra arm. Anything non-Apple that does this competes on the top end range, not entry level. Cheaping out on hardware here just means I need to buy bigger backup batteries, so either way I need to spend a ton of money if I really want to avoid Apple that much.
