Apple's iPhone X takes punishing Extreme OLED test and beats the Galaxy Note 8 for image burn-in

OLED technology is prone to image burn-in -- something that Apple worked hard to compensate for in designing the hardware and software of the iPhone X. A new and extreme stress test puts the iPhone X anti-burn-in capabilities to the test, discovering Apple's efforts have, in fact, put it ahead of the competition under the most difficult conditions.

Pitting the iPhone X, Samsung Galaxy Note 8, and Galaxy 7 Edge against one another, South Korean site Cetizen ran a 510-hour marathon test to see how long it takes to burn in an image on a modern OLED smartphone.

Interestingly, the iPhone X began showing very faint, nearly invisible signs of burn-in at the 17-hour mark, but to the surprise of the tester, after that the situation did not worsen. The burned-in images were said to be so light that they would not be seen in average daily use.

By the 62-hour mark, the Note 8 began showing a sudden and noticeable signs of burn-in, despite not having significant signs prior. The tester asked people to identify burned in parts of the screen while displaying a white image, and while they had no trouble identifying it on the Note 8, it was not visible to users on the iPhone X.

The test, first spotted by BGR, eventually ran for a whopping 510 hours, or more than 21 days -- well beyond the amount of time that any smartphone OLED display would ever show a static image in normal daily usage. Read More
