To get an idea how much power draw there is on the new Renoir based platform, we turned to BatteryBar Pro to log the power draw. The Web test is more demanding, meaning more CPU power is used, and only shows a small gain over the previous generation. In our light test, there is a big jump in efficiency when comparing to the Microsoft Surface Laptop 3 AMD edition, and as the light test is mostly an idle scenario, gives hope that Renoir has finally solved AMD’s extra power draw. Removing the battery size from the battery life equation lets us take a look at platform efficiency across the different notebooks.

In terms of overall movie playback time, the Acer Swift 3 would let you watch four complete sittings of The Avengers in a row, although you’d miss the end of the credits in the final loop. Intel has incredibly efficient hardware blocks dedicated to this, and the AMD APU can’t quite match that, but is still an improvement over Picasso. This is one area where the previous AMD APUs struggled, since it does mean offloading the video decode to the GPU. The Acer Swift 3 offers good battery life with the movie playback as well, closing in on ten hours straight with the display at 200 nits brightness.
But the results are still encouraging, with almost nine hours of runtime. That is the case here, with almost 100 minutes less runtime than the light battery test. Our revamped web test is much more demanding on the CPU, and generally especially impacts thin and light designs where the base power draw is quite low. A great comparison is the Microsoft Surface Laptop 3 15-inch, which had Picasso and a battery of similar capacity. The Acer Swift 3 does quite well in our lightest test, offering over ten hours of screen-on time. As always, the display is set to 200 nits of brightness to normalize display power across all of the notebooks. Of course battery capacity is only one side of the equation, with the other being power draw, so to test the overall battery life the notebook was run through our laptop battery suite, which consists of a low-impact web test, a high-impact web test, and movie playback from a local file. With the new Ryzen 4000 series, AMD has not only moved to the Zen 2 CPU cores, but also to the 7 nm TSMC process, so they should have a chance to rectify their previous shortcomings.ĭespite the 14-inch notebook size, the Acer Swift 3 ships with just a 48 Wh battery, which is much smaller than you would see as an average for this size of device.

Thanks to a high base power draw, both the AMD Ryzen 20 series could not match the competition in terms of outright battery life. While AMD’s rebirth in the notebook market brought with it some changes that have shaken up the laptop market, one area where AMD’s Ryzen APUs have suffered is in terms of battery life.
