Why can’t the adaptive high-brush of Android phones please users?

The first wave of new phones this year has two things in common, one is Qualcomm’s new-generation Snapdragon 8 processor, and the other is the LTPO 2.0 screen.

▲ Simple screen opening, the variable refresh rate screen will also have frame rate changes.

For the Snapdragon 8, various manufacturers do everything they can. The larger-sized VC soaking plate ensures heat dissipation, and the more conservative SoC performance scheduling ensures the power consumption level.

For LTPO, this new configuration that appeared on the flagship screen last year is like a processor, and various manufacturers are also very similar to "Eight Immortals crossing the sea, each showing their magical powers".

▲ The new generation of Snapdragon 8 processor is still not so calm.

But it backfired. Neither the performance of the Snapdragon 8 nor the actual effect of LTPO 2.0 has become the strongest advantage of this wave of new phones, but has attracted many complaints from users, most of which point to LTPO 2.0.

Looking through the forums of the first wave of new phones, the problem still revolves around lag and electricity consumption, and this is precisely the meaning of LTPO's existence. In this way, after a year of optimization, it seems that 2.0 is lonely?

"I don't want to use a high brush"

The screen is set to a standard refresh rate (60Hz), which is the setting of a colleague who is using OnePlus 10 Pro in the editorial department of Aifaner. When I asked the reason in surprise, "too much power consumption" was the answer he gave me.

Although there is no objective data to prove how much power LTPO (variable refresh rate) technology can save until now. However, in pure theory, LTPO technology does have the potential to save electricity.

The best example is the iPhone 13 Pro Max, and the longer battery life has become the reason why many people choose it. Introducing LTPO technology and adding more refresh rates, from a product point of view, the battery life is indeed stronger.

▲ The iPhone 13 Pro Max has improved significantly, both in terms of screen and battery life.

Just reverse derivation, LTPO is not the only factor, the stronger battery life may be a larger battery, and the improvement brought by the new processor A15.

On the Android side, from last year's Find X3 Pro to the current iQOO 9 Pro, from the first-generation LTPO technology to the current so-called 2.0, for me, the battery life has been significantly improved. 1 hour battery life increments.

In the same reverse derivation, it is still impossible to attribute it to LTPO, but it may also be a larger battery and stricter SoC power control.

LTPO screen comes standard, as does version 2.0

The original intention of LTPO technology is to reduce the refresh rate as much as possible without affecting the high refresh rate experience, thereby saving power.

Hardware technology can be popularized quickly, but it is finally presented in the form of products. In fact, there are some differences. There is a difference between the buyer's show and the seller's show.

The advertised LTPO 2.0 is actually more of an algorithmic manifestation, and it is also the observation and thinking of different manufacturers on the process of "using a mobile phone".

Watching video requires 24Hz, reading at 1Hz, and playing games at 120Hz. These simple scenes can be said to be a very simple distinction. Last year's LTPO was basically divided according to the software scene. In station B, it was 60Hz, Alipay was also 60Hz, information flow browsing was 120Hz, and static may be 10Hz or 1Hz.

Such a simple distinction is actually contrary to the original intention of LTPO. It affects the experience of high refresh rate and loses the advantage of high refresh rate. I also need 120Hz when swiping station B to select videos, and when the desktop is stationary, the system should actively reduce the frequency to save power as much as possible.

▲ The global limit of 60Hz in station B is not enough. It is good to limit 60Hz only when the video is turned on.

In fact, LTPO 2.0 is to improve the algorithm, considering all aspects, to reduce the "stutter" caused by the screen frequency reduction. In this way, the so-called 2.0 should be called the LTPO full version is more appropriate.

2.0 Curative effect is worrying?

From the feedback forums of various manufacturers, it seems that the problem of "stuttering" has not been solved perfectly.

At the same time, after 2.0 is attributed to the algorithm, manufacturers have also responded in a more timely manner. In short, the number and frequency of OTAs have increased significantly.

▲ ColorOS, which has always been known for its stability, has also been updated with four versions of firmware before and after.

Judging from iQOO 9 Pro, Realme GT2 Pro and OnePlus 10 Pro, it has been on the market for more than 20 days, and more than one round of repair packages have been pushed in a row. "Optimizing the dynamic refresh strategy" is the most common phrase.

If you only refer to the display refresh rate in the "Developer Options" built in each manufacturer's model, compared with last year's LTPO technology, the number of variable gears has increased, and it is no longer limited to 30Hz, 60Hz, 90Hz, and 120Hz. More gears are refined to correspond to different preset scenes.

▲ Multiple gears and variable speed are already the consensus of LTPO 2.0.

Even the Xiaomi Mi 12 Pro has a "sliding speed change" similar to the iPhone 13 Pro series, and similar to iOS, it also requires a software ecosystem to coordinate to complete the speed change.

On the other hand, OnePlus proposes a hardware-level LTPO mechanism that does not require software adaptation. In addition to a series of fixed scenes such as video and reading, OnePlus uses a low-latency chip to track the "touch" of the finger. After hand-held operation, the screen bounces back to 120Hz high refresh rate.

The description of iQOO 9 Pro on LTPO 2.0 is very "duty", but it also mentions "stepless speed change" and discards useless refresh times according to the state of use.

They all have several gears (120Hz-10Hz) from swiping the menu to the end. Turn on the input method and tap, and you can also see that the refresh rate is excited from 10Hz to 120Hz.

But in the third-party app, you can see a lot of clues. In Alipay, switch to the secondary page, iQOO and Xiaomi will be controlled by the software strategy at 60Hz, and the lag is visible to the naked eye. On the other hand, OnePlus still has a 120Hz refresh rate, and I had the same performance when I switched to an account with more balance.

Only in terms of the adaptation effect of LTPO 2.0, the OnePlus 10 Pro is indeed better.

When I told my colleague who used the OnePlus 10 Pro about this test result, he also reset the smart refresh rate option back, but he was still worried about the battery life.

For the final efficacy of LTPO 2.0, I can only say that OnePlus does the best in terms of fluency. As for the impact on battery life, much like Schrödinger's cat, it may be difficult to draw a dramatic increase in battery life from an intuitive perspective.

LTPO and the bottom layer of Android and the debugging choices of manufacturers actually have quite complex mechanisms, and there are enough professional discussions on both Zhihu and Weibo. But as far as consumers are concerned, those professional arguments are nothing more than after-dinner talk for enthusiasts, and we should focus on the comprehensive experience after landing.

▲ Software ecology, iOS has thrown away several positions of Android.

After updating several firmwares one after another, the variable refresh rate algorithms for the first wave of new phones from various manufacturers have gradually taken shape, including hardware tuning and software ecology. If "degree" is the standard, hardware forced adaptation may have a better user experience.
