Our full review page is coming soon for the Nexus 5X, but we'll be providing a few of our initial measurements and comparisons beforehand.

Display

The 5.2-inch display is already brighter than many 5-inch competitors with more accurate colors and grayscale. More notably, the smartphone does not make use of an AMOLED panel unlike its larger Nexus 6P counterpart. Contrast is roughly 1000:1, though not deep as on the Huawei P8.

Emissions

Temperature

Hot spots can already be felt nearest the earpiece even during light use, so one side of the device will almost always be warmer than the other. At its worst, we were able to measure surface temperatures just above 37 C near the rear camera.

(+) The average temperature for the upper side under maximal load is 31.5 °C / 89 F, compared to the average of 32.9 °C / 91 F for the devices in the class Smartphone.
(+) The maximum temperature on the upper side is 34.4 °C / 94 F, compared to the average of 35.2 °C / 95 F, ranging from 22.4 to 52.9 °C for the class Smartphone.
(+) The bottom heats up to a maximum of 37.4 °C / 99 F, compared to the average of 33.8 °C / 93 F
(+) In idle usage, the average temperature for the upper side is 26.5 °C / 80 F, compared to the device average of 32.9 °C / 91 F.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
