18 Jul As mentioned before, the Gram 16 manages to pack in 80 watt-hours of battery capacity despite its incredibly light weight
Battery life
At the same time, it has a fast CPU and a high-resolution 16-inch display. I wasn't too sure what kind of battery life to expect.
What I certainly didn't expect is some of the best battery life we've seen. In all our tests, the Gram 16 lasted an exceptionally long time, coming in either as the longest-lasting laptop or in the top tier.
Starting with the PCing test that stresses the CPU and GPU, the Gram 16 lasted for five hours. The next-closest laptop is the XPS 13 Full HD+ that lasted a full hour less. In the PCMark 10 Applications test that's the best measure of productivity longevity, the Gram 16 managed almost 18 hours, which is more than three hours longer than the next best, Lenovo's Yoga 9i 14. In third place is the XPS 13 at just under 11 hours.
In our web-browsing test, which loops through a series of popular websites, the Gram 16 made it to almost 14 hours. Among Intel laptops, only the Samsung Galaxy Flex 13 came close (in fact, it lasted exactly as long). Only ARM-based laptops have lasted longer, including Apple's M1 MacBook Air and MacBook Pro 13.
