The article is a bit long, it may take five or six minutes to read, but you will gain a lot after reading it.
Does anyone want to buy a favorite mobile phone, but there is no way to start, do not know how to understand the mobile phone, what is the configuration of the mobile phone, how to buy it is not pitted?
I remember that I spent 1300 yuan in the physical store to buy a mobile phone, and then found that it was very stuck, and the memory was not as much as Written, and I went to use the software to test it to know that it was deceitful. This mobile phone bought on the Internet also sold for seven or eight hundred yuan, since then I have been interested in mobile phones, began to understand a variety of understanding, read various reviews, and slowly have a certain understanding of mobile phones.
Below I will write out some of the configuration knowledge points I know about mobile phones, so that everyone can refer to them, and there are bad ones that can be proposed.
One: Processor
The processor is the most important thing for the phone, for example, the heart in the human body is the most important. Processors, also known as socs, have other combinations of CPUs and GPUs.
At present, there are four processors on the mobile phone, one is the strongest Apple A series on the surface, one is Samsung's Orion, and there is The strongest Qualcomm Snapdragon in Android, and finally the successor of Kirin, MediaTek Tianji series.
For our people, in addition to Apple, the other mobile phones used are basically Qualcomm and MediaTek processors. Samsung, in addition to their own use, basically do not take out to others, there is also a good, plus Samsung in China has no market, so can buy Samsung mobile phones and processors are very few. As for Kirin, since it was suppressed, there are very few mobile phones equipped with Kirin processors, and some are also very expensive.
Processor Ranking:
Apple, needless to say, is the strongest. The second is Snapdragon, the third is MediaTek, as for Samsung because there is no market, most people will not buy, so do not say, plus these two years are also general.
If Huawei's HiSilicon Kirin has not been suppressed, if it is still there, it will definitely be stronger than Tianji, and it is no different from Snapdragon, especially in terms of 5G network, Kirin is the strongest.
Let's talk about CPUs and GPUs, most of the daily use of mobile phones now depends on the CPU, and the main role of the GPU may be used to play games, or edit videos.
CPU and GPU architecture aspects:
Apple is self-developed, so it is the strongest. In terms of Android, Qualcomm is self-developed in addition to the GPU, and the CPU uses the public architecture. MediaTek is also, both are public versions, Samsung is also, and So is Kirin. So in terms of Android, the CPU is similar to everyone, after all, the same architecture, but in terms of GPU, Qualcomm's self-developed, so it is very powerful, more powerful than Kirin, MediaTek, Samsung.
Of course, even if it is a public architecture, the optimization is different, and the effect is different. For example, they all use the public architecture, and kirin is the strongest.
Flagship & Mid-Range:
The CPU on the general flagship, the large core main frequency is generally above 2.8hz, and the mid-range, the large core main frequency is more than 2.4hz.
For example, in the case of Snapdragon, the performance of the mid-range CPU every year is basically comparable to that of the previous generation of flagship CPUs, or almost, but it is difficult to surpass. Therefore, in terms of CPU, the mid-range and flagship are generally separated by one or two generations.
But in terms of GPUs, the mid-range and flagships are also separated by three or four generations. For example, now Snapdragon's strongest mid-range Snapdragon 7gen 1, the CPU will catch up with the level of Snapdragon 865, but in terms of GPU, even Snapdragon 855 can not reach.
Craft:
At present, there are two foundries, one is Taiwan's TSMC, and the other is South Korea's Samsung. TSMC is the best, the strongest is the 4nm process, although Samsung is also a 4nm process, but it is not as good as TSMC's 4nm process, it is better than TSMC's 6nm process.
The same performance, the smaller the process, the lower the heat, the more power saving, the stronger the performance. Therefore, the process also affects the performance. In the same process, the stronger the performance, the greater the power consumption. So now the flagship has strong performance, but the power consumption is large, the heat is large, and the power consumption is large. In the middle-end, the performance is not strong, but the power consumption is low, the heat is small, and the power saving is a little.
After all, the heat is big, in order to have a good temperature control experience, many mobile phone manufacturers reduce the frequency, so the mobile phone is not hot, but the performance is poor.
Two: screen
At present, the mobile phone has two screen materials, one is lcd, the other is oled, both have advantages and disadvantages.
lcd:
The advantage is to protect the eyes a little, the disadvantage is that it is not delicate enough, and the display is not so good. There are also a lot of brands, such as Pegasus, BOE.
're:
The advantage is that the display is good, the color is bright, and the power saving is some. Disadvantages are a little eye-catching, especially in the case of low light at night, the screen brightness is very low, and there will be strobes.
There are also several brands, but Samsung is the best, many high-end mobile phones use Samsung, such as Apple, Xiaomi, Huawei, OPPO and so on.
Speaking of screens, now divided into curved screens and straight screens, most of the Android flagships are curved screens, straight screens are few, and the middle end has curved and straight screens.
Three: Camera
I didn't understand before, looking at the camera is not good or not to think that it is to see the size of pixels, what tens of millions of pixels these. But in fact, whether it looks good or not to take pictures is mainly to look at the sensor. A good sensor, even if it is 48 megapixels, is better than a bad 64 million pixels.
At present, the sensors used in mobile phones are Sony and Samsung. Comparing the two, the most used, or the best is Sony, for example, last year, many high-end mobile phones in Android used Sony imx766 sensors, 50 million pixels.
Now good mobile phones generally have these lenses:
1. The main camera is the most powerful, mainly used for photography. 2. Telephoto lens, that is, to shoot some distant scenes, put the assembly clear. 3. Ultra-wide angle, can shoot the most area, such as taking a group photo, so that you don't have to run farther to take a picture. 4. Macro, that is, when shooting close-ups, very close objects, you can shoot very clearly, such as ants, flowers.
Also, good phones generally have iOS optical image stabilization, rather than that kind of electronic image stabilization. If you have optical stabilization, taking pictures or shooting videos is not so mushy, there is no shaking, but it is very stable.
Four: Run memory
Now Android, the general mid-range low-end is 6G, and the high-end is 8G. It can also be used, but 12g is better, because the memory is large, not much to kill the background. Android runs memory, no matter how big, boot basically eat half.
As for 16g, personally feel that there is no need to buy, 12 is enough, of course, there is money to say. As for the open virtual memory is not recommended to open, it is useless, but consumes life. The extra is changed by storage.
And the specifications, now the mobile phone is divided into two kinds, generally the middle and low end are lpddr4x, high-end words lpddr5. The gap between the two generations may not be very large, not very obvious. 5 words may save some power, performance is stronger.
Five: Storage (Flash)
Now Android is generally 128g to start, high matching 256g. Flagship words, generally 256g start. The high match is 512g, of course, there are also some top matching, storage 1t.
Specifications, now Android flagships are basically ufs 3.1 or 3.0, the gap between these two is not obvious, is a small upgrade.
Some mid-range words, some use ufs3.1, some use ufs2.1. For example, the lower emmc5.1 has long been eliminated. When UFS3 did not come out, UFS2.1 was used on flagships, and EMMC5.1 was used in the mid-range or low-end.
The gap between EMMC5.1 and UFS2.1 is large, while the gap between UFS2.1 and UFS3.0 is also large. This gap is larger than the memory ddr4x and ddr5. The better the flash specifications. Installing software, opening software, transferring file data is fast.
Six: Charging and battery
At present, the fastest charging brand is OPPO, the second is vivo, and the third is Xiaomi. The fastest charge at present is 150w, full of 4500 mAh battery, about 12 minutes. It takes about 15 minutes at 120w. It's about 30 minutes at 80w. 65w is about 35 minutes.
Battery, currently divided into single cell and double cell, single cell, generally charging slow, but power consumption is also slow. If the battery is double, the charging is fast and the power consumption is also fast. Huawei has always used a single battery, so Huawei's 66W charging is actually similar to other people's 50w, but Huawei's battery is durable.
Seven: System
This is the second most important part of the phone, if the processor is the heart, then the system is the brain.
At present, there are three systems on the mobile phone system...
1.ios
The most fluid system, because it is closed, so there is no rogue software, there are few ads, so smooth. But because it is closed, it has low playability, few functions, and a lot of limitations. For example, some of the software downloaded costs money, and some third-party software cannot be downloaded. Unlike Android, all kinds of apps can be downloaded.
2. Android
Because it is open source, everyone can use it, and now Android phones are all using Android systems, such as Xiaomi, Meizu, OPPO, vivo, these systems, are modified and customized on the basis of Android. After all, native Android is too simple, not good-looking, and there are not many features.
Android mobile phones are highly playable, all kinds can be played, because of open source, so there are more rogue software, more ads, so it is stuck for a long time.
3. Hongmeng
This is Huawei's system, and it will be a year or two out. It's really embarrassing. On the interface function, it is similar to Android, and there is no difference in use, not to say that you don't know that this is Hongmeng, and think it is Android.
Say that it is Android, in addition to the underlying code these are not the same, the use of Android format, the application of these are Android ecology. Compatible with the previous Alibaba cloud OS system with The Android system.
Saying that it is not Android, what is separate from Android in the underlying architecture is not based on Android modifications.
In fact, there have been some mobile phone systems in the past, such as Microsoft, such as Symbian.
Well, the above seven points are most of the knowledge points for mobile phones, understand these, you basically understand mobile phones. You can help family and friends introduce mobile phones.
If you like it, you can pay attention to oh, discuss the problem of mobile phones later, and if there are any deficiencies, you can also correct oh.
