To test the battery life of a laptop, we use PCMark 8’s in-built battery benchmark – which loops its ‘Home’ benchmark until the battery fails. We do this with the screen brightness set at 50%.
5:22 is a great score here. Given that the battery benchmark is a relentless assault on any laptop, we can expect real-world performance to be around double the benchmark result. As such, the XPS 13 should easily last a full day at the office, making it a great option if you are looking for a long-lasting productivity machine.
