A:Answer Thank you for the question. Basically, the battery life depends on how hard the laptop is working. If the power saving mode is not enabled, you'll deplete the battery more quickly. Screen brightness, use of several tabs simultaneously, and WiFi, all deplete battery life. (Battery life tested by HP using continuous FHD video playback, 1080p (1920x1080) resolution, 150 nits brightness, system audio level at 17%, player audio level at 100%, played full-screen from local storage, headphone attached, wireless on but not connected. Actual battery life will vary depending on configuration and maximum capacity will naturally decrease with time and usage).
