Do you know your phone number? Listening every day to different configurations revealed on Internet, are you a little confused? When buying a mobile phone, are you a little confused after listening to various options given by seller? It doesn't matter, the editor has prepared for you some basic knowledge about mobile phones that you can popularize in a nutshell.
RAM and ROM
When we buy a mobile phone, we need to choose 4GB+64GB version or 6GB+128GB version. These two numbers are RAM and ROM. RAM is RAM. The more RAM, smoother your phone will run and there will be no lag when there are multiple tasks open in background. Nowadays, most mid-range phones have 4GB RAM, and some high-end phones have 6GB and 8GB RAM. ROM is storage capacity, more ROM, more things phone can hold. Currently, most flagship mobile phones have 64G and 128G, and 256G is relatively rare but not non-existent. The capacity of RAM and ROM is increasing, which is a trend. It always seems that one day mobile phone will hold whole world.
The processor is most important part of a mobile phone, just like human brain. Current processors can be divided into single-core processors, dual-core processors, quad-core processors and eight-core processors. Most mobile phones choose eight-core processors. Major brands include Qualcomm, MediaTek, Apple, Huawei and Samsung.
How do you rate a good processor or a bad one? Some mobile phone brands often say that they are octa-core processors, but do not say what brand of processor it is, so this processor should not be good. A large number of cores does not yet mean good performance, it should be considered comprehensively. When officially introducing processor, I would like to say that it is based on TSMC xxnm process technology with 4 large AXX cores + 4 small AXX cores. Note that smaller number before nm, lower power consumption, and larger number after A, better performance. Qualcomm processors are best choice for people who play large games, but Apple, Huawei and Samsung use their own processors, so no options.
A screen is made up of dots, or pixels. Resolution is ratio of pixels, higher resolution, sharper image. There are currently four resolutions with highest ratio on market: 720x1280, 1920x1080, 2K (2560x1440), and 4K (3840x2160). When choosing a resolution, pay attention to size of battery and screen, because higher resolution, more energy it consumes. This is why most inexpensive mobile phones are said to have long battery life. No need to deliberately pursue high resolution, average mobile phone has a resolution of 1080P, after all, it's not bad for human eye.
Photography is very difficult. Apple's camera isn't high resolution, but photos are better than some high resolution phones. Since visual effect of mobile phones is related to many components, such as sensors, photosensitive elements and, of course, pixels, official will not talk much about internal things. Therefore, before buying a mobile phone, you need to look at evidence to see specific shooting effect of this mobile phone. In addition, pay attention to aperture, size of aperture will affect amount of light entering, smaller number after F, larger aperture, better background blur effect, it depends on personal preference.
System is operating system that runs on mobile phone. Currently, most famous of them are Android, iOS, YunOS and Windows phone. Apple's popularity is inseparable from its user-friendly and easy-to-use iOS system. The Android system is main system of domestic mobile phones, and it also has its own merits. Differences and struggles between mobile phone systems are still almost nothing but confrontation between Android and Apple.
Now do you understand basics of working with mobile phones? The next time you buy a cell phone, keep your eyes peeled.
