![]() ![]() The Acer Nitro 5 managed almost exactly ten hours of runtime. This is one area where AMD struggled in previous generations of the Ryzen laptop platform, but is another area where they have become very competitive. Generally, the least demanding task is video playback, since the video decode can be offloaded to efficient, fixed-function hardware in the CPU’s media blocks. The Acer Nitro 5 did very well on this test, achieving just a hair over nine hours. This test is actually less demanding than our web workload, due to the idle time, and scores are generally a bit higher. Each test is given ten minutes to complete, so if a system gets the work done quicker it earns extra idle time. The PCMark 10 test leverages some of the sub-tests from their performance workloads and runs them in sequence. Looking at the normalized result, which removes the battery size from the equation, the Acer Nitro 5 gaming laptop does not manage to touch the smaller, lighter laptops in energy efficiency, but is not too far off either, despite the larger display and more powerful internals. ![]() That is a far cry from the 12-15 hours we see on Ultrabooks, but still a solid time for a 45-Watt class gaming laptop. The Acer Nitro 5 achieved 397 minutes here, which is just over 6.5 hours. Our web battery life test is very demanding on the CPU, and as such can really drain the battery down compared to tests that are mostly idle. To see how the Acer Nitro 5 fares in runtime when not hooked to power, it was set to 200 nits brightness, and run down from 100% battery until it shut down on several different workloads. Although typical gaming systems are not generally known as road warriors, due to their high weight, and powerful internal components, on systems that include the ability to turn off the discrete GPU, such as the Acer Nitro 5, battery life can be fairly competitive.Īcer has only outfitted the Nitro 5 with a 51 Wh battery, which, considering the 15.6-inch chassis, is definitely on the small side, but battery size is only one half of the equation. ![]()
