The battery life of a traditional laptop depends on several factors, including the laptop's specifications, usage patterns, and power-saving settings. On average, most laptops can last anywhere from 4 to 8 hours on a single charge. However, it's important to note that battery life may vary depending on the tasks performed and the settings used. To maximize battery life, it is recommended to adjust the screen brightness, close unnecessary applications, and enable power-saving modes when not in use.
