HP Spectre x360 15 Review: A Versatile, Attractive, Premium Ultraportable
Spectre x360 15: Battery Life, How We Test And Acoustics

|
The Spectre x360 15 is equipped with a non-removable 6-cell (79.2 Whr) lithium-ion battery, with HP advertising up to 12 hours and 45 minutes of run time. In other words, all-day battery life. Of course, BatterEater Pro prides itself on pummeling battery life claims, and so we didn't see anywhere near 12 hours and 45 minutes in this test. However, the Spectre x360 15 did stay awake for an impressive 169 minutes, earning itself at spot near the front of the pack.
Moving on to the next test, our custom HotHardware video loop takes a 1080p HD video with a 16Kbps bit rate and loops it repeatedly, with 1 minute break intervals in between. A timer log file increments minutes of uptime and a final tally is recorded before system shutdown is stored in the log. This is a lighter duty test that is still a bit more strenuous than many office productivity tasks, but it's not nearly the strain that Battery Eater puts on a system.
When we turned our attention to our home-brewed Video Loop test, the Spectre x360 15 managed to avoid shutting down for 318 minutes, or just shy of five hours. While not best in class, that is very good.
Depending on how your use this laptop, running it for the entire workday (and beyond) is possible, especially if you're mostly doing low-key tasks such as word processing and surfing the web. Obviously the more demanding the task, the lower the battery life will be. Opting for the 1080P screen option will also extend battery life.
Acoustics
This is an actively cooled system, though the only time you'll hear noise from the cooling system is when loading up the CPU or GPU. When that happens, it is definitely audible, though not obnoxiously loud or high pitched.
