Korean tech site and phone marketplace Cetizen tested OLED displays on the iPhone X, the Samsung Galaxy Note 8, and the Samsung Galaxy S7 Edge for 510 hours to magnitude burn-in as partial of its ongoing iPhone X review. In all 3 cases, progressing a immobile picture for distant longer than a normal use case was required to furnish conspicuous burn-in. The iPhone X took longer to vaunt distracting burn-in than the other two phones.
The site left the phone screens displaying a immobile picture at limit liughtness for the test’s whole duration. The iPhone X first showed signs of burn-in at 17 hours, but even then the picture influence was not bad adequate to be conspicuous in normal use. The Galaxy Note 8 took longer to vaunt retention, but by 62 hours it was some-more poignant than what was seen on the iPhone X, such that a ubiquitous user could brand the burned-in spots on the Note 8 at that time, but not on the iPhone X.
By the finish of the 510-hour test, all 3 phones had very conspicuous picture influence that could potentially be permanent. Cetizen did not report trying any methods of clearing the picture up. In OLED TVs, influence can start after several hours—especially with things like network logos on promote TV, or determined UI elements in video games—but it is customarily simply reversible with the help of picture influence remedies enclosed in the TV’s software. But the OLED panels in phones are done very differently than those in TVs, so it’s misleading how much the influence is reversible in phones. It could change from device to device.
All told, the Samsung Galaxy S7 Edge achieved almost, but not quite, as good as the iPhone X, and the Note 8 exhibited the misfortune retention. When we reviewed the iPhone X, Apple told us that it had implemented certain anti-retention measures in further to its common fine-tuning of the iPhone display. But the company didn’t divulge what those measures were. Whatever they were, this comparison suggests they were at slightest rather effective.
None of these 3 phones achieved feeble adequate in this test that owners should be worried. It seems that with high-quality panels done by Samsung (the iPhone X uses a Samsung-manufactured panel), OLED display record has overcome some of its many concerning problems. LG’s phone panels competence still be a opposite story—for now.
