Does anyone want to buy a favorite mobile phone, but do not know how to start, do not know how to understand the mobile phone, mobile phone configuration and what, how to buy just not to be pit?
I remember that xiaobian spent 1300 yuan to buy a mobile phone in the entity store at that time, and found that it was very card and memory was not as much as written, so I used the software to test it. This mobile phone on the Internet to buy also sell 700 or 800 yuan, from then on I am interested in mobile phone, began to understand, see a variety of reviews, slowly have a certain understanding of the mobile phone.

The following I put me on the phone to know some configuration knowledge points to write out, let everyone reference, there are bad can be put forward.
One: Processor
The processor is the most important to the phone, for example the heart is the most important to the human body. A processor, also known as an SOC, has a CPU, a GPU and other combinations.
At present, the processor on the mobile phone is also four, one is the strongest apple a series on the surface, one is Samsung's Orion, and it is the strongest Qualcomm Snapdragon on Android, and finally it is the successor of Kirin, Medifa Division Phecda series.

In addition to Apple, most of our mobile phones are qualcomm and Mediatek processors. As for Samsung, except for their own use, they don't takeout food to other people, which is also very good. Besides, Samsung doesn't have much market in China, so there are few mobile phones and processors from Samsung. As for Kirin, since the crackdown, handsets with Kirin processors are rare and 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 I don't say, and the past two years are just so-so.

If Huawei's Hisickirin is not being suppressed, if it is still there, it will certainly be stronger than Breguet and neck and neck with Snapdragon, especially when it comes to 5G networks.
Now let's talk about CPU and GPU. Most of the daily use of mobile phones depends on CPU. The main function of GPU may be used for playing games or editing videos.
CPU and GPU architecture:
Apple is self-developed, so it is the strongest. And Android, Qualcomm in addition to GPU is self-developed, CPU is the public version of the architecture. So is Mediatek, both are public, so is Samsung, so is Kirin. So in terms of Android, everyone has the same CPU, after all, the same architecture, but in terms of GPU, Qualcomm has developed it itself, so it is very powerful, much stronger than Kirin, Mediatek, Samsung and so on.

Of course, even if the public version of the architecture, optimization is different, the effect is not the same. For example, both are public architecture, and Kirin is the strongest.
Flagship and mid-end:
For the CPU on the general flagship, the main frequency of the large core is generally above 2.8Hz, and for the mid-end, the main frequency of the large core is above 2.4Hz.
In snapdragon's case, every year the mid-range CPU has been able to catch up with the previous flagship CPU, or almost, but it's hard to beat. So in terms of CPU, mid-range and flagship are generally separated by a generation or two.

But on the GPU side, midrange and flagship are three or four generations apart anyway. For example, the most powerful snapdragon midend Snapdragon 7Gen 1 has the same CPU as Snapdragon 865, but the GPU can't even reach Snapdragon 855.
Process:
At present there are only two OEM, one is Taiwan TSMC, one is South Korea Samsung. TSMC is the best, currently the strongest is 4nm process, although Samsung is also 4nm process, but it is not as good as TSMC's 4nm process, it is just better than TSMC's 6nm process.
The same performance, the smaller the process, the lower the heat, the more electricity, the performance is stronger. So the process also affects the performance. Under the same process, the stronger the performance, the greater the power consumption. So now the flagship performance is strong, but the power consumption is large and the heat is large, power consumption. In the middle end, the performance is not strong, but the power consumption is low, the heat is small, and the power is saved.

After all, the temperature is high. In order to have a good temperature control experience, many mobile phone manufacturers reduce the frequency, so the phone is not hot, but the performance is poor.
2: the screen
Currently, there are only two kinds of screen materials for mobile phones, one is LCD and the other is OLED, both of which have advantages and disadvantages.
lcd:
The advantage is to protect the eye a bit, the disadvantage is not delicate enough, show not so good. There are also many brands, such as Tianma and BOE.

oled:
The advantages are good display, bright color, save some electricity. Disadvantages of eye injury a bit, especially in the evening under the condition of dark light, screen brightness is very low, there will be stroboscopic.
There are 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, there are now curved and straight screens, android flagship most of the curved screen, very few straight screen, mid-end words have curved and straight screen.

3: the camera
I did not understand before, see the camera is good to see the pixel size, what tens of millions of pixels these. But in fact, it depends on the sensor. A good sensor, even 48 megapixels, is better than a bad 64 megapixel sensor.
SONY and Samsung are the only sensors currently used in mobile phones. For example, last year many middle and high-end android phones are using SONY IMX766 sensor, 50 million pixels.

Now, good phones usually have these shots:
1. Master photography, the most powerful, is mainly used for photography. 2. Telephoto lens, that is, shoot some scenes far, put it clearly. 3. Super wide Angle, can take the largest area, such as group photo, so that you do not have to run far to take a picture. 4. Macro is to take close-up shots of very close objects, such as ants, flowers and so on.
Also, good phones tend to have ios optical security, not electronic security. With optical stabilization, taking photos or videos is not so blurry, no shaking, but very stable.
Four: running memory
Now for Android, it's generally 6GB for the middle end and low end, and 8GB for the high end. It can also be used, but 12GB is better, because of the large memory, not so much killing background. Android's running memory, no matter how big, eats half of it when you turn it on.

As for 16G, I feel there is no need to buy it, 12 is enough, of course, I have money. As for the open virtual memory is not recommended to open, nothing useful, but consumption of life. The extra is stored.
And specifications, now mobile phone is divided into two kinds, generally low-end lPDDR4X, high-end words LPDDR5. The difference between the two generations may not be that big, it's not obvious. The 5 might save a little bit of power, but the performance might be better.
Five: Storage (flash memory)
Now Android generally starts with 128GB, with 256GB for high specs. Flagship words, general 256G start. High specs are 512GB, but there are also some top-spec specs that store 1TB.
In terms of specifications, android flagship is now ufS3.1 or 3.0, which is not obvious and belongs to a small upgrade.

Some mid-range speakers use UFS3.1 and some use UFS2.1. For example, the lower emmc5.1 has long been phased out. When ufs3 is not available, ufs2.1 is for the flagship and emmc5.1 is for the mid or low end.
Emmc5.1 is far from ufs2.1, and ufs2.1 is far from ufs3.0. This gap is larger than ddr4X and DDR5 memory. The better the flash specification. Installing software, opening software, and transferring file data is fast.
Six: charging and batteries
At present, the fastest charging brand is OPPO, vivo is the second, and Mioba is the third. The fastest charge so far is 150W with a full 4500 mah battery, which takes about 12 minutes. About 15 minutes for 120W. About 30 minutes for 80W. About 35 minutes for a 65W.

Battery, currently divided into single cell and double cell, single cell, general charging slow, but electricity consumption is also slow. With dual cells, it charges quickly and consumes power quickly. Huawei has always used a single cell, so huawei's 66W charging is virtually the same as others' 50W, but Huawei's battery is durable.
Seven:
This is the second most important part of the phone. If the processor is the heart, the system is the brain.

There are only three systems on the phone right now...
1.ios
The most fluent system, because closed, so no rogue software, advertising is also less, so smooth. But because it's closed, it's less playable, less functional and has a lot of restrictions. For example, some of the downloaded software costs money, and some third-party software cannot be downloaded. Unlike Android, you can download all kinds of apps.
2. The android
Because it is open source, everyone can use it. Now android phones all use Android system, such as Xiaomi, Meizu, OPPO, Vivo and other systems, are modified and customized on the basis of Android. After all, native Android is clunky, unattractive, and doesn't have many features.
Android mobile phone can play high, all kinds of can play, because open source, so rogue software is much, advertising is also much, so a long time on the card.

3. HongMeng
It's a Huawei system. It's only a year or two away. It was really awkward. Interface function, and Android similar, use is no difference, not to say you do not know this is hongmeng, still think it is Android.
Android, except for the underlying code, which is different, it's all in Android format, and it's all in android ecosystem. Compatible with The previous Alibaba cloud OS system android system.
Say not Android, what is the underlying architecture separate from Android, not based on Android modification.

In fact, there used to be some mobile phone systems, such as Microsoft, such as Symbian.
Well, the above seven points are most knowledge points for mobile phones, understand these, you basically understand mobile phones. You can introduce your family and friends to your cell phone.
