QUESTION
What are the best laptops for writers with long battery life?
Top pick: Apple MacBook Air 13-inch (M3 or M4, depending on current pricing). For most writers, it has the best mix of long battery life, quiet operation, excellent keyboard/trackpad, light weight, and reliable sleep/wake behavior.
If you prefer Windows, start with the Lenovo ThinkPad X1 Carbon or Microsoft Surface Laptop 7. If you want the longest practical unplugged writing time for the money, look at an ASUS Zenbook 14 OLED configuration with a recent efficient chip.
