How Long Should A Laptop Battery Last On A Single Charge?

Modern laptops typically last 4–12 hours on a single charge, with ultrabooks reaching 8–12 hours and gaming models only 2–4 hours. Battery life depends on laptop type, charger quality, and power-saving settings such as dimming the display, closing background apps, and using power-saving modes. Maintaining moderate temperatures (68–77 °F) and avoiding deep discharges or prolonged full-charge plugging help preserve battery health.
