Ulefone Power Armor 16S Review

Display

Ulefone Power Armor 16S has a 5.93-inch IPS display with an HD+ resolution of 720 x 1600 px. With its sharp corners and thick bezels, it looks like an older-generation one. The display of our review unit has a standard brightness and is comfortable for viewing in most environments. Our usual measurements of the white and black luminance, static contrast ratio, and color temperature of the display are published below. If you follow our smartphone reviews, you already know that for a more realistic result, we make two different measurements - on a single frame that displays 50% white and 50% black and on two separate frames displaying a fully white and a fully black screen.

A single frame, 50% white / 50% black

Brightness	White luminance	Black luminance	Contrast	Color temperature
100 %	427.122 cd/m2	0.341 cd/m2	1253 : 1	7463 K
0 %	13.38 cd/m2	0.015 cd/m2	892 : 1	7181 K

Two separate black and white frames

Brightness	White luminance	Black luminance	Contrast	Color temperature
100 %	475.939 cd/m2	0.348 cd/m2	1368 : 1	7449 K
0 %	14.817 cd/m2	0.015 cd/m2	988 : 1	7353 K

The maximum brightness of the Power Armor 16S display measured from the center on a fully white screen is 475.939 cd/m². This brightness is achieved during the two separate black-and-white frame measurement. In the other type of measurement on a 50% white and a 50% black screen, we measured a white luminance of 427.122 cd/m². The ratio between the white and black luminance for each type of measurement is relatively close, hence, the close contrast levels - 1368:1 and 1253:1. The temperature of the white point is quite agreeable in the 7300-7500 K range.

Position	Left	Center	Right
Top	475.363 cd/m2 / 7273 K	465.921 cd/m2 / 7313 K	462.363 cd/m2 / 7351 K
Center	470.942 cd/m2 / 7379 K	476.635 cd/m2 / 7370 K	477.796 cd/m2 / 7426 K
Bottom	436.620 cd/m2 / 7372 K	427.742 cd/m2 / 7423 K	441.823 cd/m2 / 7464 K

Our brightness uniformity measurement shows that the display of the Power Armor 16S delivers is not evenly bright but the differences between the two tiers are not significant. The top one-third has an average brightness of 466 nits. The middle one - 474 nits. The bottom one-third has an average brightness of 435 nits. The temperature of the white point at all levels is around 7300-7500 K. The CIE diagram shows that the display covers less than 100% of the sRGB color space, especially in the blue, cyan, green, red, and pink hues. The light green, yellow, and orange hues may look punchier. The display panel has a traditional vertical striped RGB subpixel arrangement.
