Best answer: According to official figures from Dell, the new XPS 15 7590 with a 97Whr battery will last up to 20 hours on a single charge. That`s crazy talk because, unfortunately, you`ll likely see a few hours short of that claim in real-world usage depending on your laptop configuration and how you use it. The latest and greatest: Dell XPS 15 (7590) (From $1,100 at Dell) Incredibly efficient computing Just how long your laptop will last depends on the size of the battery, as well as the power draw of installed components. The new Dell XPS 15 comes rocking two battery capacities: 56Whr and 97Whr, the latter being better overall across all configurations.
