The article is a bit long, it may take five or six minutes to read it, but you will gain a lot after reading it.
Is there anyone who wants to buy a desired cell phone, but can not start, do not know how to understand the phone, and what is the configuration of the phone, how to buy it without being pitted?
I remember I was in the physical store spent 1300 yuan to buy a phone, the back found very card, memory is not as much as written, went to test with software to know the fraud. This phone is also sold online for seven or eight hundred dollars, from then on I was interested in the phone, began to understand a variety of, look at a variety of reviews, and slowly have some understanding of the phone.
The following I will write out some of the configuration knowledge I know about the phone for your reference and any bad ones can be brought up.
The processor is the most important for the phone, for example, the heart is the most important in the human body. The processor, also called soc, has a CPU and GPU and other combinations.
The current processors on the phone are four, one is the strongest Apple a series, one is Samsung's Orion, and the strongest Android Qualcomm Snapdragon, and finally the successor to Kirin, MediaTek Tiangui series.
For our countrymen, with the phone in addition to Apple, the others are basically Qualcomm and MediaTek processors. Samsung, in addition to their own, basically do not sell to others, there is also very good, plus Samsung in China is not much market, so you can buy Samsung's phones and processors are very few. As for Kirin, since the suppression, equipped with Kirin processor phones are very few, there are also very expensive.
Apple, needless to say, is the strongest. The second is Snapdragon, the third word MediaTek, as for Samsung because there is no market, most people will not buy, so it is not said, plus the two years are also general.
If Huawei's Heisi Kirin is not suppressed, if it is still around, it is definitely stronger than Tiangui, and Snapdragon, especially in the 5g network, Kirin is the strongest.
The following talk about the CPU and GPU, now most of the daily use of cell phones are relying on the CPU, the main role of the GPU may be used to play games, or editing video.
CPU and GPU architecture:
Apple is self-developed, so the strongest. As for Android, Qualcomm is self-researching in addition to the GPU, the CPU is using the public version of the architecture. MediaTek is also, both are public version, Samsung is also, Kirin is also. So Android, the CPU is similar to everyone, after all, the same architecture, but the GPU, Qualcomm self-research, so it is very powerful, more powerful than Kirin, MediaTek, Samsung, these are many.
Of course, even if they all use the public version of the architecture, the optimization is different, the effect is not the same. For example, if you are using a public architecture, Kirin is the strongest.
Flagship and mid-range:
General flagship on the CPU, the main core frequency generally on more than 2.8hz, the mid-range, the main core frequency of more than 2.4hz.
In the case of Snapdragon, for example, every year the performance of mid-range CPUs can basically catch up with the previous generation of flagship CPUs, or almost, but it is difficult to surpass. So the CPU, mid-range and flagship is generally just one or two generations apart.
But the GPU, the mid-range and flagship how also separated by three or four generations. For example, now Snapdragon's strongest mid-range Snapdragon 7gen 1, the CPU will catch up to the level of Snapdragon 865, but the GPU, even Snapdragon 855 can not reach.
At present, there are also two foundries, one is Taiwan TSMC, one is South Korea Samsung. TSMC is the best, the strongest is currently 4nm process, although Samsung is also a 4nm process, but it is no better than TSMC's 4nm process, it is also a little better than TSMC's 6nm process.
The same performance, the smaller the process, the lower the heat generation about, the more power saving, and the stronger the performance played. So the process is also affecting the performance. The same process, the stronger the performance, the greater the power consumption. So now the flagship performance is strong, but the power consumption heat, power consumption. Mid-range words, the performance is not strong, but low power consumption, heat generation, power saving a little.
After all, the heat is big, in order to have a good temperature control experience, many cell phone manufacturers to reduce the frequency, so the phone is not hot, but the performance is poor.
At present, the phone on two screen material, one of the lcd, the other is oled, both have advantages and disadvantages.
The advantage is a little eye protection, the disadvantage is not fine enough, the display is not so good. Brand words are also quite a lot, such as Tianma, BOE these.
The advantage is that the display is good, colorful, power saving some. Disadvantages then hurt the eyes a little, especially at night in the case of dark light, the screen brightness is very low, there will be strobe.
There are several brands, but Samsung is the best, many high-end cell phones with Samsung, such as Apple, Xiaomi, Huawei, OPPO, etc..
Speaking of the screen, now divided into curved and straight screen, most of the Android flagship is curved screen, straight screen is rare, the mid-range words have curved and straight screen.
Previously do not understand, look at the camera is good think is to see the size of the pixel, what tens of millions of pixels these. But in fact, how good is the photo, mainly depends on the sensor. Good sensor, even 48 megapixels, but also better than the bad 64 megapixels.
The current sensor used on the phone is also Sony and Samsung. Comparison of the two, the most used, or the best is Sony, for example, last year, many high-end Android phones are used is Sony imx766 sensor, 50 million pixels.
Nowadays, good phones generally have these lenses:
1. the main camera, is the most powerful, the main photo with. 2. telephoto lens, is to shoot some scenes far away, put the General Assembly clear. 3. ultra-wide angle, can shoot the most area, such as taking group photos, so you do not have to run a little far to shoot. 4. macro, is to shoot close-up, very close objects, you can shoot very clear, such as ants, flowers, these.
There is also the fact that good phones generally have ios optical stabilization, rather than the kind of electronic stabilization. If you have optical stabilization, take pictures or shoot video is not so mushy, no shake, but very steady.
Now Android words, generally low-end are 6g, high-end words are 8g start. Can also be used, but 12g better, because the memory is large, not how to kill the background. Android running memory, no matter how big, the boot basically eat half.
As for 16g, I feel no need to buy, 12 is enough, of course, the money is another story. As for the open virtual memory is not recommended to open, nothing useful, but consume life. The extra is used to store the change.
The two generations of the gap may not be very big, not very obvious. 5 words may save some power, a little stronger performance.
V:Storage (flash memory)
Now Android is generally 128g to start with, 256g if high. flagship words, generally 256g to start with. The high end is 512g, of course, there are some top of the line, storage 1t.
Specifications, now Android flagships are basically ufs3.1 or 3.0, the gap between the two is not obvious, is a small upgrade.
Some mid-range words, some with ufs3.1, some with ufs2.1. for example, lower emmc5.1 has long been eliminated. ufs3 did not come out, ufs2.1 is used in the flagship, emmc5.1 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 even bigger than the memory ddr4x and ddr5. The better the flash specs. Installing the software, opening it, and transferring file data is fast.
Currently the fastest charging brand is OPPO, the second is Vivo, and the third is Xiaomi, right? The fastest charging 150w, full 4500 mAh battery, about 12 minutes. 120w, about 15 minutes. 80w, about 30 minutes. 65w, about 35 minutes.
The battery, currently divided into single-cell and dual-cell, single-cell, generally slow charging, but also slow power consumption. If the double cell, charging fast, power consumption is also fast. Huawei has always used a single cell, so Huawei's 66w charge, the actual and others 50w about the same, but Huawei's battery durability.
This is the second most important part of the phone, if the processor is the heart, then the system is the brain.
Currently there are just three systems on the cell phone system ......
The smoothest system, because it is closed, so there is no rogue software, and there are few ads, so it is smooth. But because of the closed, so low playability, less features, there are many restrictions. For example, some of the downloaded software requires money, and some third-party software can't be downloaded. Unlike Android, all kinds of apps can be downloaded.
Because it is open source, all people can use, now the Android phones are using the Android system, like Xiaomi, Meizu, OPPO, Vivo these systems, are modified on the basis of Android customization. After all, the native Android is too simple, not good-looking, and not many features.
Android phones are highly playable, all kinds can play, because of open source, so there is a lot of rogue software and advertising, so time is stuck.
This is Huawei's system, out just a couple of years, right? Seriously quite embarrassing. Interface function, and Android is almost the same, use is not much different, do not say you do not know is this is Hongmeng, and thought it was Android.
Said Android well, in addition to the underlying code these are not the same, with the Android format, the application of these are Android ecology. With the previous Alibaba's cloud os system compatible with the Android system.
Said not Android well, the underlying architecture of what is separate from Android, and not based on Android on the modification.
In fact, there used to be some cell phone systems, such as Microsoft, such as Symbian.
Well, the above seven points are for most of the cell phone knowledge, understand these, you basically know a lot about cell phones. Can help family and friends to introduce the phone.
