with normal usage - 4.5 hours. But if I run something in dGPU - I can burn through battery in like an hour. Under windows they told it will get better battery life mostly because of better drivers support. But I never tested it. This is Dell Precision M6600. This one and most other Precisions will consume similar amount of power from PSU. Not sure why all the downvotes. Even MacBook Pro I have requires 85W
