![]() ![]() Given the phone’s inaccuracies seemed to be more prevalent in higher saturations in the blue and red spectrum, and this test doesn’t contain patches in that region of the gamut, it means that the remaining test colours perform extremely well. In our GMB chart with common colours such as skin tones, the iPhone 12 Pro behaves admirably. Generally it looks that our sample here is again performing a little better than our 12 Pro sample. The iPhone 12 has slightly better results, with the blue and magenta error being less pronounced on this phone. Below maximum intensity, the colours are all showcasing dEITP errors below 3 which is the just perceivable threshold for the average eye. SRGB colour saturations on the iPhone 12 Pro are quite excellent, with the biggest error margin happening at maximum saturation blues and magentas, with also a slightly oversaturated red. Average colour temperature landed in at 6520K while white landed in at 6462K, with less dominant reds than on the other phone. Oddly enough, colour temperature on the 12 behaved better than our 12 Pro sample. The 12 seems to have slightly better gamma behaviour on the higher levels, but in exchange showcases worse off gamma at the lower levels, clipping lower level colours to black earlier than on the 12 Pro, which had near perfect behaviour here. The iPhone 12 seems to showcase a different calibration than the 12 Pro, further evidence of the two different panels employed on the two models. It’s not an issue, but a little less perfect than we had come to expect from iPhones. Although the total average white balance over all levels lands in at an excellent 6502K, actual whites land in at 6372K. ![]() The white balance for whites actually is a tad warmer than it should be with some clearly higher-than-average levels of red. Apple still showcases higher gamma at higher level colours, but that’s only a minor imperfection. Generally speaking, there’s very little to criticise the device here as there’s generally an excellent performance. We start off the detailed measurements with the greyscale performance of the iPhone 12 Pro. The latter figure is the highest and brightest amongst any OLED device we’ve ever measured, although it’s not all that much brighter than the iPhone 11 Pro models. In terms of display brightness, we pretty much measure figures in line with Apple’s advertised marketing and specifications, with the new iPhone 12 reaching 631cd/m² and the iPhone 12 Pro reaching a significantly higher 839cd/m². Data is collected and examined using Portrait Display's CalMAN software. As always, we thank X-Rite and SpecraCal, as our measurements are performed with an X-Rite i1Pro 2 spectrophotometer, with the exception of black levels which are measured with an i1Display Pro colorimeter. We move on to the display calibration and fundamental display measurements of the iPhone 12 screens. This points out to a quite different lamination process and maybe different polarisation layer between the two models. The iPhone 12 showcased a larger off-axis brightness drop-off and what I would consider a more classical OLED off-axis colour tint, while the iPhone 12 Pro behaved significantly better with almost perfect off-axis brightness and colour performance. We’re not exactly sure as to the actual manufacturing differences between the two panels, but one thing that I immediately noticed as being different between the two models is their viewing angles. ![]() The new iPhone 12 and iPhone 12 Pro have on paper almost the same display characteristics, both being 6.06” OLED panels with 2532 x 1170 resolution, however they differ in their characteristics when looking at the peak maximum brightness achieved, with the regular iPhone 12 model peaking at 625 nits and the 12 Pro peaking at 800 nits.
