I have been the using the 2026 Dell XPS 14 (OLED, Ultra X7 358H) for the last two weeks and am pretty disappointed with the battery life. According to several reviews, I should be getting more than 10 hours in real world use, but I am ranging between 6-8 hours. For reference, my use case is 75% screen brightness, 120hz with dynamic refresh rate on, light web browsing and video streaming, along with Spotify in the background. Is there something wrong with my unit or is this what I should expect?
