This should be the most frequently spoken phrase in cellphone circles recently.
Driven by OnePlus, OPPO, Xiaomi, Samsung and other manufacturers, the high refresh rate has become a hot spot of demand. Friends who have experienced it have said that they are "too strong."
If you want to get paid, you have to pay. First, you have to spend more; second, you have to endure battery life. The Samsung Galaxy S20, which was released a while ago, has a lifespan because of 120Hz.
Samsung Galaxy S20 in 120Hz mode
Samsung Galaxy S20 series is the representative of high refresh rate mobile phones. The upgrade from 60Hz to 120Hz is like knocking over the lubricant.
After the foreign media got the three mobile phones of this series, it conducted an endurance test for a high refresh rate. Test results show that in 60Hz mode, the Galaxy S20 Ultra can last for 12 hours and 23 minutes. However, if you switch to 120Hz, the battery life will be reduced to more than nine hours, and the decline will be about 20%.
In the same way, S20 + decreased from 12 hours and 40 minutes to 8 hours and 30 minutes, a decrease of 33%; S20 + decreased from 12 hours and 12 minutes to 7 hours and 45 minutes, a decrease of 36%. It seems that the smaller the battery, the more noticeable it is.
These endurance data is the reason why Samsung limits 2K + 120Hz. why?
There is a reason for electricity
As we all know, the screen is a big consumer of electricity.
Past habits tell us that the higher the resolution, the brighter the screen, and the more power it consumes. But this year, one more electric tiger. After the 120Hz mode is enabled, the screen flashes twice as fast as 60Hz per second, and the power consumption naturally increases.
The increase in refresh rate not only affects screen power consumption. From 60Hz to 120hz, the picture information that the processor needs to process is also doubled directly, and the power consumption is indirectly increased.
In addition to power consumption, what are the shortcomings of high refresh rates?
Yes, the smooth performance brought by the high refresh rate is extremely strong.
However, the current high refresh rate experience is not comprehensive enough.
High refresh rate screens have been in the public eye for some time, but not many games are supported. Even more sad is that some games also need to be individually adapted for the model.
High refresh rate "I can't go back after using it", yes.
But the reality is, I have to go back when encountering these applications that cannot use high refresh rate. Jumping from a high refresh rate to 60Hz is not uncomfortable, but occasionally weird during switching, is it too much in the background?
There are also videos. Most of the videos we see now have nothing to do with high refresh rates, and their utilization of 120Hz may be less than a quarter.
Since there are so many questions, everyone should ask them from the heart.
Do we really need a high refresh rate screen?
As long as you have experienced it, you will definitely give a positive answer, after all, the improvement it brings is too intuitive.
Mobile phone manufacturers also think so. The upcoming Huawei P40 series and OnePlus 8 series will both adopt high refresh rate screens. Over time, the high brush will become the flagship standard, and even the mid-range standard.
As for all the issues mentioned above, the trend we are currently seeing is that high refresh rate manufacturers are constantly solving these difficulties.
Let's talk about battery life first.
High refresh rate will be the real hammer, but in the end it costs more electricity, and whether you can save a little, mainly depends on optimization.
OPPO Find X2 Pro automatically reduces the refresh rate of some "not-perceived" scenes through the intelligent refresh rate. In addition, 65W flash charge is also a good way to make up for battery life.
The Samsung Galaxy S20 Ultra is unprecedentedly equipped with a 5000mAh large battery, and saves power by limiting 2K, 120Hz at the same time. It is reported that Samsung is optimizing the 2K + 120Hz display of the Galaxy S20 series, which is expected to be launched within three months.
The upcoming Huawei P40 may be equipped with a 5500mAh battery.
In addition to battery life, there is content.
To solve the content problem, we must gradually establish a high frame rate ecology. Game manufacturers expand support for high frame rate; apps should avoid incompatibilities; and video platforms should provide high frame rate content and encourage creativity.
If the ecological establishment is hopeless, mobile phone manufacturers can also take a different approach. OPPO Find X2 has a built-in MEMC chip, which can promote 30 frames of video to 60 or 120 frames by inserting frames.
In the future, the experience of high refresh rate will definitely get better and better, this is an unstoppable trend. When you buy a mobile phone next time, you may want to think more: "Is there a high refresh rate?"
