The battery of this laptop typically lasts around 4 to 5 hours for web browsing or video playback under moderate brightness settings. Specifically, tests show about 4 hours and 46 minutes of web browsing and just under 5 hours in similar usage scenarios. However, during gaming or heavy workloads, battery life is significantly shorter, often under 2 hours, as the laptop shifts to high-performance components. This device is more suited as a desktop replacement rather than for long unplugged use. Battery life is considered average for a powerful gaming laptop of this size and specification.
