We tested the MSI WS63 7RK with Battery Saver turned on and a 50 per cent screen brightness, using the PC Mark 8 Create battery test, which runs a series of productivity tasks until the power runs out. These test scripts stress the graphics performance a little, although not specifically professional 3D. It's supposed to represent a mixture of everyday creative tasks.
The result of around two hours isn't stunning, but this is quite an intensive set of activities. Nevertheless, we would have liked to see an hour longer. Two hours of creative work away from the power plug is useful, but not outstanding. If you're only using the system for the odd bit of word processing and Web browsing, however, you should be able to expect at least twice the duration. We achieved around five hours of non-intensive activities.
