In the following benchmarks we employ two very different battery life tests--Battery Eater Pro and a custom 1080p HD video loop test--to prove out battery life with our test group of machines and the Acer Swift 7. In all tests, Windows 10 Quiet Hours have been enabled and displays are calibrated with lux meters on pure white screens to as close to 115 lux as possible. For the average notebook this is somewhere between a 45 - 60% brightness setting.
Since notebook displays significantly affect power consumption and battery life, it's important to ensure a level playing field with respect to brightness of the display for battery testing. However, since many notebook displays vary in brightness at each respective brightness setting in Windows, this calibration with the meter is also critical to ensure all displays are set to as near identical brightness as possible before testing.

Acer makes much of the Swift 7’s battery life, and we can see why. The laptop provided excellent battery life scores, outshining the other slim laptops in the intensive Battery Eater Pro test, including the XPS 13. In our custom video playback testing, the machine fared well, but landed just above the middle of the pack.
Acoustics: Thanks to its passive cooling, the Acer Swift 7 is silent, even under load. The keyboard is very quiet too, making this a perfect laptop for working in environments where noise is kept to a minimum.
