iPhone 15 Pro reappears "screen burn door", users are overturned after buying it

It has only been just half a month since the iPhone 15 series was officially launched. Problems such as severe heating, speaker failure, and dust in the camera have already caused huge controversy, making people worried about Apple's quality control.

Recently, Weibo user "Kang" shared about the "screen burn-in" situation of iPhone 15 series models. It can be found from the exposed pictures that, In dark light environments, image afterimages are clearly visible on the phone screen. Generally speaking, such serious "screen burn-in" will only appear in OLED display devices that have been used for several years, and the iPhone 15 series has been on sale for less than a month.

So far, some media have given different opinions on the "screen burn-in" problem of iPhone 15 series models: iOS's unique protection mechanism has caused image persistence and has nothing to do with physical damage or aging. As for whether there is a problem with the screen quality of the iPhone 15 series itself, or whether the iOS algorithm is responsible, we need to wait for Apple's official response.

What is really worthy of attention is that if the iPhone 15 series really has a screen defect, then the first batch of users may miss the official 14-day no-reason return and exchange after-sales service , it seems to be another big pitfall to return/repair in the future.

#iPhone 15 "screen burn", who is going to take the blame?

Due to the self-luminous nature of OLED displays, as the use time increases, image afterimages left by aging sub-pixels will inevitably appear on the screen, commonly known as "Screen burn".

Different from the edge yellowing and vignetting caused by the screen aging of LCD materials, the lifespans of the red, green and blue sub-pixels of OLED displays vary. There are different levels, and the arrangement and sub-pixel ratio are also different, and the "screen burn-in" situation is also very different. The most common one is the image afterimage exposed on the iPhone 15 series.

Since the iPhone X, Apple has used OLED displays in its mobile phone product lines. Starting with the iPhone 12 series, it has completely eliminated LCD displays. Although the application of OLED has enabled the iPhone to achieve higher brightness, a thinner and lighter body, and more system-level features, the lifespan of its screen has been controversial.

#Judging from the recent "rollover" of the iPhone 15 series, maybe the new A17 Pro will take the blame first.

It is reported that " The "screen burn-in" problem mostly occurs in the iPhone 15 Pro and iPhone 15 Pro Max. Coincidentally, these two models have previously been caught in the public opinion that the device temperature is too high. Recently, Apple pushed the iOS 17.0.3 system version to solve the problem of excessive temperature in some models.

In fact, when the external lighting environment is at high brightness, iPhone 15 Pro/Max will stimulate higher brightness to ensure that the display content is clearly visible, while the body If the temperature is too high, there is a chance that ions will remain on the screen and image afterimages will appear. Under normal circumstances, image afterimages will not stay for long.

But according to the user who broke the news According to the statement, even after the phone has just been turned on, there will be image afterimages. It is obvious that irreversible "screen burn" has occurred, which does not match the short-term image afterimages caused by overheating of the fuselage.

The iPhone 15 series "screen burn" problem may be caused by a screen hardware defect or an iOS algorithm bug. If it is the latter, then users only need to wait for the next system version to be fixed. Can. But if it's really a screen defect, I'm afraid I can only ask the official after-sales service for an explanation.

Is there nothing Apple can do to prevent "screen burn"?

#In order to solve the problem of the service life of OLED display substrates, Apple also has a unique set of algorithms.

#According to the official introduction, the built-in algorithm of iOS can independently calculate the usage of individual pixels, thereby providing stable display calibration data and mitigating screen aging. Doesn't this sound very noble? But the reality is not so good.

Although Apple will monitor it separately The lifespan of a single sub-pixel, but "monitoring" will not extend the life of the sub-pixel. If iOS finds that a certain sub-pixel is aging rapidly, it will choose to match the surrounding sub-pixels, or even display the entire block. The screen must match the data of the problematic sub-pixel.

As time goes by, the first problem that occurs with the iPhone's display is the decrease in brightness. This is the result of iOS's unique algorithm.

The mechanism adopted by the Android camp is often "non-fixed display", which means moving pixels inadvertently to ensure that the lifespan of each pixel is equal. With the support of such an algorithm, some fixedly displayed icons, status notifications, and even screen-off displays will not have a great impact on the life of the display screen.

The iPhone 14 released last year The biggest features of Pro and iPhone 14 Pro Max are "Smart Island" and "All-Weather Display". The former provides a new interactive mode, while the latter makes up for the shortcomings of the iPhone's standby messages. These two functions, one is permanently displayed at a certain position on the screen all year round, and the other lights up the screen for a long time, both of which are taboos of "screen burn".

Regarding "all-weather display", Apple officially stated that this feature will be presented at a minimum refresh rate of 1Hz and will not completely turn on/off pixels, which will have minimal impact on the service life. . However, the iPhone 14 Pro series models are indeed more prone to "screen burn-in" problems than previous models.

Of course, no matter what No type of display can avoid aging, but the algorithm mechanism of iOS does not seem to put display life first. Now that the iPhone 15 series has been exposed to the problem of "screen burn" again, I am afraid it is due to the quality of the hardware, algorithm and temperature. The result of controlling multiple comprehensive factors.

Prevent "screen burn", please keep these tips

The advantages of OLED display are indeed not small. It is thin, light, high-brightness, high-contrast, and saves more power than LCD screens. But there are also some tips and methods on how to avoid rapid aging of an OLED display.

#As we mentioned earlier, OLED displays are most taboo with fixed display content. For example, staying on the same page for a long time will accelerate the aging of sub-pixels. Then image afterimage appears. During use, try to avoid displaying the same static image for a long time. When playing some videos with a lot of still images or fixing controls, it is best to switch to another interface and stay for a while.

#Secondly, try to avoid being in a high-brightness state for a long time. In the report "About Super Retina Display and Super Retina XDR Display on iPhone" officially provided by Apple, it is also mentioned that iPhone users are recommended to turn on the automatic brightness adjustment function, mainly to avoid users using it at ultra-high brightness for a long time, which will affect Screen life.

Finally, change the wallpaper frequently , mode is also necessary. Although manufacturers can intervene in system-level elements such as fixed display status and controls through algorithms to delay aging, wallpapers are set by users themselves, and it is difficult for algorithms to ensure that pixels move regularly. Frequently changing wallpapers and occasionally switching to dark mode can also reduce the problem of "screen burn".

#But it should be said that mobile phones are only consumables after all, and there is no need to use them carefully. However, iPhone users should pay attention. The official price for replacing the screen of the iPhone 15 Pro has risen to 2,698 yuan, and the iPhone 15 Pro Max has reached 3,198 yuan. This price is really not cheap.

Written at the end

Since iPhone X, Apple has adopted OLED displays in almost every generation All iPhones have various problems, the most prominent of which is the "green screen door" of iPhone 12 and iPhone 13.

The "green screen door" of iPhone 12 and 13 is mainly due to a problem with the demura compensation algorithm. After the official push of a new version of the iOS system, most users have green screen problems. has also been resolved. It is still unclear whether the iPhone 15 series also has defects in software algorithms.

Of course, from consumers From a perspective, no matter what causes the iPhone 15 series "screen burn-in" problem, how to formulate an after-sales strategy is the most important. After all, most users who discovered this problem have missed the best return and exchange cycle. If Apple had not If the problem cannot be solved through software updates, then a more reasonable after-sales plan needs to be provided to appease users.

In any case, if you find that the iPhone 15 series model you are using has a "screen burn-in" problem, please contact after-sales service decisively.
