The performance of a smartphone

Software is just as important as the hardware required for a smartphone to perform well. For now, let me briefly talk about how software can make it even better.

When it comes to software, it is divided into OS and UI. For a smartphone, both are important.

An OS is, as we all know, an operating system installed on your phone. Here, Android refers to the OS installed on your phone, and the numbers indicate its version. For example, if your phone has Android Nougat installed, the OS version is Android 7.0, 7.1.1 or 7.1.2. The OS can do everything the hardware does to do the functions that need to be done on the phone. So if you look at how well your OS version works, you can tell if the hardware is working properly or not.

Here it’s easy to choose the right OS. If you buy a new phone, only buy one that runs the latest OS. Even if you do not get the latest OS, it is a good idea to choose one that is one level lower than the OS. For example, the latest version of Nougat should now run the same version of Android 6.0 Marshmallow as before. This is because the newer the OS version, the better the features. But we need to talk about another important UI.

The user interface (UI) is important enough to make a difference in the performance of smartphones. Visually, the UI is like the clothes you wear. It is as if a person could give a rough idea of what kind of person he is by the way he looks at his clothes. It is easier to work in light clothes, and it is not easy to work in tight clothes. The same goes for the UI. It works just like the OS.

With a heavy UI, there is no reason to speed up your phone. Similarly, if the UI is not too fast or heavy, the phone will be able to perform as quickly as possible. Therefore, you should choose a fast UI that is not too heavy on the phone. So the question is, how do you know if the UI is slow? So is Animation Times fast as a measure? Is bloatware loading fast? These can be measured. The less loading time, the faster the UI. But if you want to customize your UI with a lot of features, you have to use heavy UIs.

The good news is that there are a lot of intermediate UIs, not just the Heavy and Light UI. Simply put, Heavy has its own set of features that you can use to customize your Light. Intermediate UIs allow you to customize as many useful features as you want.

Then you can look at the OS and UI to see how good the hardware is. That’s why it’s important to have good software, not just hardware in a phone.

Normal User There are three types of users: mid-end users who have a fair amount of technical knowledge and proficient Pro users. So here’s how you’ve know what kind of user you are, and after reading these five tips, you can decide what kind of phone is right for you.

Performance is the most important thing you can use every day. If the performance of a smartphone is not good, the longer you use it, the more unhappy you will be. So this article is going to cover some of the key features of every smartphone you buy. We hope this helps you the next time you buy a phone.

To begin with, the amount of performance a phone needs will vary depending on what each user will be focusing on. Some people want to play big games, so they need high performance. Some will play multitasking-focused games, so mid-range is fine. But some people use a web browser every day without playing any games. For those who want to read messages and use social media like Facebook, this is not a big problem.

The performance of the first smartphone was based on the so-called SOC (System on a chip) (CPU); GPU RAM ROM (internal storage) and software. Today I’m going to talk about the CPU.


The CPU is the place where you can give instructions to perform various functions on a phone. The CPU of smartphones is now called the System on a Chip (System on a Chip ) because it includes other systems besides the main processor. This SOC determines the performance of a smartphone, so it is very important to choose the right CPU (processor).

CPU and what to measure? CPU performance will vary depending on how the three components, Cores, Clock Speeds, and Process Technology, are integrated.

Some say that an octa-core processor is always better than a quad-core processor. But the CPU does not really work with just a few numbers. The CPU itself is divided into two cores, called Big or High-power cores and Small or Low-Power cores. For example, the Cortex A73 is a high-power core, while the Cortex A53 is a low-power core. The picture shows only Quadcore and Octacore. Hexacore and Decacore will work the same way.

As the name implies, high-power cores are more powerful and less energy-intensive, while low-power cores are less powerful and less energy-intensive.

Clock Speed

Another clock speed is called the speed measurement that the cores perform. The higher the clock speed, the faster the performance. For one thing, the performance is better, but the clock speed is higher, so more heat is released. Now it’s time to talk about process technology. CPU clock speeds are measured in Gigahertz (GHz).

Even if the CPU is a combination of HP and two LPs, the HP core has a faster clock speed and the LP cores have a slower clock speed. But it would be more accurate to call them energy-efficient cores than slow-power cores with slow clock speeds. As I said, it’s not always hot at all clock speeds.

Process Technology

You may have heard of the 14nm process. Here you might think of a nanometer as the size of a processor. In fact, 14nm is so large that it is invisible to the naked eye.

So a nanometer is the distance between two parallel transistors on a processor. Process Technology refers to these distances. Currently, 10nm and 7nm processors are still being developed, and the smaller the process technology, the better the performance.

So you might ask, what does it have to do with reducing the distance between transistors? In fact, by reducing the distance between the two, the distance between the two is reduced and the heat is reduced, resulting in less heat. The smaller the processor, the faster the CPU can run. Even with the same core, a 14nm processor is cheaper and uses less heat than a 28nm processor. So the performance is better. Here is what you need to know about CPU.

The GPU is also a processing unit that works like a CPU. But it also has graphics that display on the screen. GPUs have more processing units than CPUs. Graphical data can only be generated if these units are calculated simultaneously. Even now, there are really powerful GPUs out there. For example, Qualcomm’s Adreno 530 and 540, and ARM’s Mali G71 MP20 are among the most powerful.

Like CPUs, GPU speeds are also measured in clock speed. So far, however, the clock speeds for GPUs have been around MHz (MegaHertz). Soon, in just a few months or a year, smartphones will reach clock speeds of around GHz (GigaHertz).

In addition to the clock speed, there is another factor in measuring speed. It is called GFLOPS (Gigaflops) and it is also a unit for measuring performance. FLOPS stands for Floating Point Operation Per Second, which measures the performance per second. GFLOPS will be Giga Floating Point Operation Per Second.

If the clock speed and gigaflop power are very good, then this is a good GPU. For example, the Adreno 505 has a low clock speed (450MHz) and 48.6 Gigaflops. The Adreno 506 (650MHz and 130 Gigaflops) has about average performance, while the Adreno 540 (710MHz and 567 Gigaflops) has a much higher GPU performance.

The difference here is that Gigaflops are not that big of a difference. Gigaflop has a smaller Gigaflop, and a GPU with a very fast clock speed can perform better than a GPaf with a slower clock speed. For example, the Mali-T860 MP2 has 520 MHz & 35.3 Gigaflops, so it has better clock speed than the Adreno 505 with 450 MHz & 48.6 Gigaflops. So one of the main things to keep in mind about GPU is that it has a fast clock speed. That’s all there is to know about the GPU.

RAM (Random Access Memory)

It acts as an intermediary between the CPU and storage. The CPU takes data from the operating system (OS) to get the job done. However, because the OS is stored on internal storage, it is fast but does not match the transfer rate sent by the CPU. This means that if you have to go to internal storage and retrieve data, you will have to work with RAM in between. RAM is faster than internal storage. The reason is that some of the data is stored in RAM and is faster because it can only be accessed from the RAM in between without having to go to internal storage whenever the CPU needs it.

DDR (Double Data Rate) is not used when specifying the type of RAM. The actual use is LPDDR (Low Power Double Data Rate). It can only be said that DDR is a low performance version. As a result, it may not be as powerful as desktops.

With 2017 coming, no smartphone will have LPDDR1 RAM. Even LPDDR2 is pretty rare. Previously, older SOCs, the Snapdragon 400 and 410, supported both versions, but now no smartphone makers use them. Instead, they use low-frequency LPDDR3.

LPDDR3 is the type used in low- and mid-range smartphones. Modern SOCs can support LPDDR3, with high performance from 800MHz to 933MHz. However, most high-end phones use LPDDR4. It can support up to 1866MHz frequency. But now even mid-range SOCs can support LPDDR 4. (The Snapdragon 630 can support up to 1333MHz of LPDDR4 RAM.)

In summary, LPDDR3 RAM can be found in Snapdragon 430, 450, 625, 652 SOCs. LPDDR4 RAM is used in Snapdragon 630, 660, 820, 821, 835 and so on. But even if you buy a phone with the second SOC mentioned above, you can still go to the official website to see if it uses LPDDR4. This is because some are still only compatible with LPDDR3.

The best smartphone RAM in 2017 is the upgraded LPDDR4X. The technology is still in its infancy and can only be supported by a Snapdragon 835 SOC. At the moment, it can do only a few key things over LPDDR4: the most important is Reduced Power Consumption.

There are only two factors that determine how much RAM you need.

NUMBER 1: If you use a web browser, I will sit and chat. You can watch Youtube videos and listen to streaming music with 2-3GB of RAM. Otherwise, if you have apps running in the background and switching to other apps, If you play high-end games and use VR, you need about 3-4GB of RAM. More than that, for example, if you want to edit 4K videos with your phone or use 3D, you need about 4-6 GB of RAM.

NUMBER 2: It would be a mistake to think that just having a lot of RAM on a phone works well. With a lot of RAM, using low-end SOCs may not work as well as you might think. Similarly, low RAM and high-end SOC do not matter.

For example, if you use a low-end processor like the Snapdragon 425 or 430, you do not need to add more than 3GB of RAM. The same goes for the larger Snapdragon 821 or 835, but with less than 3GB of RAM, performance won’t be as good. With it, at least 4GB of RAM will work. In conclusion, if you choose high SOC, you can not choose low RAM. If the SOC is low, it will not work with a lot of RAM. So you need to choose RAM and SOC regularly depending on what you use it for.

ROM (Internal Storage)

Let’s talk about ROM, also known as Internal Storage. All you have to do is buy the phone and consider the internal storage. However, you can choose the amount of storage that suits your budget. Here we will talk about the different storage options available for smartphones. Before we get into that, let’s take a look at the picture.

The most common storage type found on most smartphones now is eMMC (embedded Multi Media Card). They are very fast and the latest eMMC 5.1 has a read speed of 200-300 MB per second and a write speed of almost 100MB per second. In the past, eMMC versions were even slower. eMMC cards are suitable for both regular and mid-end users. However, the downside of eMMCs is that they have low IOPS (Inputs & Outputs Per Second / Input-Output Operations Per Second). IOPS determines how well storage handles operations, such as extracting and importing data from a database. This is the problem that eMMCs are facing in the latest high-end SOCs. So it was UFS that took its place.

UFS stands for Universal Flash Storage and is faster than eMMCs. Only flagship smartphones use UFS 2.0 and 2.1. Compared to eMMC, UFS 2.0 has twice the speed of Read Speed <500-600 MBPS> and Write Speed <150-180 MBPS>. UFS 2.1 is faster than 2.0 and has read speeds <600-800 MBPS> Write speeds . All in all, flagship phones are using faster versions to avoid the hassle of operating them.

Compared to eMMCs, UFS has an IOPS score of about 10 times. This is the main reason why only UFS is used in the latest SOC heights. If you buy U Phone with internal storage using UFS, you do not have to worry about slowdowns.

This is all about ROM today, and I’ve going to talk about software that is very important for a phone in the future.
