The high refresh rate of the screen (abbreviation: high brush) has now become a must for many people to buy mobile phones. But as we all know, the high brush is an electric tiger, and the current brush brush is off after opening.
As a result, many people bought mobile phones before, and the first thing was to turn off 5G and global high brushing.
But since the iPhone 13 Pro also used a high brush, the endurance has not decreased but increased, with a small battery of three thousand mAh, directly to the top few of the endurance list.
Everyone was confused, called good guys, and saw the high brush for the first time and saved electricity.
So what is the strength of apple brushing? The machine brother first gave everyone a simple nagging:
The high brush on the iPhone 13 Pro is called LTPO adaptive refresh to be precise.
First of all, let's take the word apart – what is "LTPO": it is a display technology.
Compared with traditional display technology, LTPO can maintain the same level of display effect under the condition of lower power consumption.
At the same time, it also has the feature of being able to display screen content at different refresh rates. In special cases, it is also possible to maintain a still picture with a very low refresh rate.
What about "adaptive refresh"?
That is, according to the content displayed on the screen, you will choose the screen refresh rate.
You can also observe for yourself. In fact, the high brush we can perceive is only when sliding the screen. In more cases, the screen content is relatively static.
If at this time, the screen is still running in a high-brush state, it is really "increasing power consumption". So adaptive refresh will be at this time, choose a less high refresh rate.
But how do you do that? This is the characteristic of LTPO's variable refresh rate. After the combination of the two, you can flexibly adjust the screen refresh rate according to the display page to achieve the ultimate goal of power saving.
Nowadays, LTPO adaptive refresh, Xiaomi Mi 12 Pro and OnePlus 10 Pro have been used.
The same is LTPO, the same adaptive refresh, I believe that many fans also have questions: which one is better?
Next, it is up to me to present the Xiaomi Mi 12 Pro to everyone, compared with the LTPO adaptive refresh of the OnePlus 10 Pro:
Reaction speed
Just now we also elaborated that the core of adaptive refresh and power saving is to pull a full high brush when it is used and reduce the refresh rate when it is not in use.
Therefore, the evaluation criteria for this round are - who can be in a high refresh rate state as little as possible.
The camera was aimed at the two contestants and recorded the change in the refresh rate of the screens of the two players:
At the same brightness and still screen, xiaomi and oneplus have a frame rate of 10 Hz. But at the moment of finger touch, both directly increase the refresh rate to 120 Hz.
But the sharp-eyed friends must have found: Brother Eh, it seems that the speed of the Xiaomi Mi 12 Pro is fast
Yes, after the actual measurement of the machine brother, it is inferred that the frame lifting logic of the Xiaomi Mi 12 Pro is: touch first.
That is, as long as the touch is sensed, the refresh rate is directly pulled to the full.
(Xiaomi Mi 12 Pro)
And one plus is the picture priority, if the UI is not "jittery", even if the machine brother is crazy to provoke, it is also 10Hz textured.
From this point of view, the LTPO frame raising strategy of the two companies is indeed different. However, it is not possible to distinguish between good and bad. We also have to look at the performance of the frame drop~
The Xiaomi Mi 12 Pro paused slightly after the animation was still before it began to reduce the refresh rate.
Even the frame rate can be seen, it is 120-60-30-10, four gears. In fact, there is still a 90 that has not appeared.
And the OnePlus 10 Pro, almost at the moment when the picture is still, the refresh rate plummets to 10 Hz.
Of course, the minimum refresh rate of OnePlus can reach 5 or 1 Hz. Only at a higher brightness screen.
Pure subjective judgment, one plus's frame reduction is more fierce, and Xiaomi is gradually decreasing. The machine brother actually prefers xiaomi, which is more spiritual.
However, the machine brother also found that mainly because Xiaomi's linear animation is more smooth, many times it looks as if the animation has stopped, but in fact, it has not stopped, which is also part of the reason for the slow frame reduction.
But our daily use is not staring at the frame rate every day. Instead, use different refresh rates for different scenarios.
This is also what the two manufacturers jointly describe: intelligent recognition scenarios.
Differences for daily use
The general meaning is that even within the same app, the frame rate will be different in different situations.
Take Weibo as an example, when there is no video playing on the page.
Xiaomi Mi 12 Pro, on the other hand, still needs the page to be still and pause for a moment before dropping frames.
As for why the obvious step-by-step decline just now did not occur.
The machine brother found that it was because Weibo did not have a linear animation adapted to MIUI. Even if it slides quickly, it will slow down to a standstill with great damping.
But if there is a video on the screen, the Xiaomi Mi 12 Pro will lock frame 60 to ensure smooth playback of the video.
Of course, if we swipe the screen at this time, the refresh rate will quickly increase to 120 Hz.
In station B, the performance of the Xiaomi Mi 12 Pro is consistent with Weibo, locking 60 frames in the case of video playback.
Even if you pause the video, it's the same.
But on the OnePlus 10 Pro, the machine brother saw a different situation.
The screen will automatically match the number of frames according to the video, and the B station will watch the video at 30 frames by default, and lock at 60 frames after turning on the bullet screen.
If you are playing a high bitrate 60 frame video, the OnePlus 10 Pro will also sync to 60 Hz
This will ask the fan: the same LTPO, why can one plus do this?
This is the advantage of OnePlus global adaptive refresh.
OnePlus' priority is system-level, and it matches the refresh rate entirely based on what is displayed. This is different from Xiaomi's need for third-party adaptation.
But it doesn't matter, one plus this side is mainly a time difference. Only need the App developers on the Xiaomi side to keep up with the adaptation, and in the end they can have the same experience.
Battery life
In any case, the ultimate purpose of manufacturers to refresh the screen with adaptive is to live. Otherwise everyone wants to pull full at 120 Hz
So what is the endurance of the two of them?
The brother conducted two hours of testing, half an hour for each test. The final result is as follows:
Unsurprisingly, the biggest difference is that Station B plays video. OnePlus' refresh rate of 30 Hz is indeed more power-efficient than Xiaomi's.
But the machine brother is still a little curious: if the whole movie is played, what will the result be?
So brother Ji watched "Dune" again.
After the final playback, the Xiaomi Mi 12 Pro consumes 26% of the power, and the OnePlus 10 Pro is 18%.
The power consumption gap between the two is 8 blocks.
Of course, we can't judge how much electricity we can save based on the power consumption. After all, the battery size is different: the OnePlus 10 Pro is 5000 mAh, and the Xiaomi Mi 12 Pro is 4600 mAh.
But I have to admit that OnePlus's current 30-frame playback is indeed more advantageous. Xiaomi's developers have to step up adaptation.
In addition, we can also see that in the brush headlines and vibrato, which are almost the whole frame lock app, the power consumption of the two is actually no difference.
After this round of testing, the LTPO adaptive refresh rate of domestic mobile phones has indeed kept up with the pace of the iPhone.
From the look and feel, it has been fought with Apple back and forth.
But, to be honest, this wave is catching up, but not quite catching up.
Mainly because, in terms of endurance, it is indeed almost meaningless, and the brother feels that this should be the direction that domestic mobile phone manufacturers need to work on next.
To truly "catch up" with Apple, Android phones still have to become a real "dragon trainer" and hold the processor.
It is also necessary to work hard in many aspects such as application adaptation and system optimization, and I have to say that the task is heavy and the road is long.
