Below, I will write out some knowledge points I know about the configuration of mobile phones for your reference. Any questions can be asked.
The processor is the most important for a mobile phone, for example, a person's heart is the most important. Processor, also known as soc, has a combination of CPU and GPU.
For China people, except Apple, other mobile phones are basically processors from Qualcomm and MediaTek. Samsung's words, except for their own use, are basically sold to others, and it is good to have them. In addition, Samsung has no market in China and seldom buys Samsung's mobile phones and processors. As for Kirin, since it was suppressed, there are very few mobile phones equipped with Kirin processors, and some are still very expensive.
Processor ranking:
If Huawei's Hisilicon Kirin has not been suppressed, if it still exists, it is definitely better than Tianqi, and it is on a par with Snapdragon, especially in the aspect of 5g network.
Let's start with CPU and GPU. Nowadays, most of the daily use of mobile phones depends on CPU. The main function of GPU may be to play games or edit videos.
CPU and GPU architecture:
Of course, even if they all use public architecture, the optimization is different and the effect is different. For example, they all use the public version architecture, and Kirin is the strongest.
Flagship and mid-range:
Generally, the CPU on the flagship has a large core frequency above 2.8hz and a mid-range large core frequency above 2.4hz.
But in terms of GPU, the midrange and flagship are separated by three or four generations. For example, the CPU of Snapdragon's strongest mid-range Snapdragon 7gen 1 has caught up with the level of Snapdragon 865, but in terms of GPU, even Xiaolong 855 can't reach it.
Technology:
Under the same performance, the smaller the process, the lower the calorific value, the more energy-saving and the stronger the performance. 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 very strong, but it consumes a lot of electricity, heat and electricity. Mid-range, the performance is not strong, but the power consumption is low, the calorific value is small, and the electricity is saved.
After all, the high fever persists. Many mobile phone manufacturers reduce the frequency in order to have a good temperature control experience, so the mobile phone is not hot, but its performance is poor.
At present, there are two kinds of screen materials for mobile phones, one is lcd and the other is oled, both of which have their own advantages and disadvantages.
Liquid crystal display:
Organic light emitting diodes:
Its advantages are good display effect, bright colors and power saving. Disadvantages are a little eye-damaging, especially in the case of dark light at night, the screen brightness is very low, and 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 and OPPO.
I didn't understand it before, but it depends on the camera. I think it depends on the pixel size, what tens of millions of pixels. But in fact, whether taking pictures is good or not depends mainly on the sensor. A good sensor, even 48 million pixels, is better than a bad 64 million pixels.
Nowadays, good mobile phones generally have these shots:
1. The main camera is the most powerful and is mainly used for taking pictures. 2. telephoto lenses are some telephoto scenes, which will be clear after zooming in. 3. Super wide angle, you can shoot the most areas, such as taking a group photo, and you can shoot without running far. 4. Macro, that is, taking close-ups, can be taken clearly when you are close to objects, such as ants and flowers.
Now if you use Android, the low-end devices are all 6g, and the high-end devices are all 8g. It's ok, but 12g is better, because the memory is large and it doesn't kill the background very much. Android runs memory, no matter how big it is, it basically eats half when it is turned on.
As for 16g, I don't think it is necessary to buy it. 12 is enough. Of course, wait until you have money. As for the open virtual memory, it is not recommended to open it, which is useless and consumes life. The extra ones are all changed by warehouse.
In terms of specifications, there are now two kinds of mobile phones, generally lpddr4x in the middle and low end and lpddr5 in the high end. The gap between the two generations may not be great or obvious. If it is 5, it may save some power and have better performance.
Now Android generally starts at 128g, and if it is high, it will be 256g. Flagship, generally starting at 256g. The high match is 5 12g. Of course, there are also some top matches, storing1t.
Some mid-range words, some use ufs3. 1, and some use ufs2. 1. For example, the lower emmc5. 1 has long been eliminated. When ufs3 didn't come out, the flagship used ufs2. 1, and the low-end used emmc5. 1.
There is a big gap between emmc5. 1 and ufs2. 1, and there is also a big gap between ufs2. 1 and ufs3.0, which is bigger than the memory ddr4x and ddr5. The better the flash memory specification. Installing software, opening software and transferring file data are very fast.
In terms of batteries, there are currently single batteries and dual batteries. For single batteries, charging is generally slow, but power consumption is also slow. If you have two batteries, you can charge quickly and consume electricity quickly. Huawei has always used a single battery, so Huawei's 66w charging is actually similar to others' 50w, but Huawei's battery is durable.
This is the second most important part of the mobile phone. If the processor is the heart, then the system is the brain.
At present, there are only three mobile phone systems. ...
1.ios
The smoothest system, because it is closed, there is no rogue software and there are few advertisements, so it is very smooth. But because it is closed, it has low playability, few functions and many restrictions. For example, some downloaded software costs money, and some third-party software cannot be downloaded. Unlike Android, all kinds of apps can be downloaded.
2. Android
Android phones are playable and can be played in all kinds. Because of open source, there are a lot of rogue software and advertisements, which will get stuck after a long time.
3. HarmonyOS system
This is Huawei's system, which will come out in a year or two. It's really embarrassing. The interface function is similar to that of Android, and there is no difference in use. You don't even know it's HarmonyOS, but you think it's Android.
Say it's not Android. What is the underlying architecture separated from Android? Not based on Android modification.
In fact, there used to be some mobile phone systems, such as Microsoft and Saipan.
Ok, the above seven points are probably most of the knowledge points of mobile phones. Knowing this, you will basically understand the mobile phone. You can introduce your family and friends to your mobile phone.
