Nowadays, it’s confusing which smartphone is better for us. Further to that, many of us don’t understand the specification of the mobile phone and we just buy it. Therefore, after buying the phone then we realize that it’s not made for our use.
So, in this post, I will tell you about some details which I learned before buying my new smartphone.
Many of us did notice that value 164.2 x 75.9 x 9.1 mm while reading any smartphone specifications. Let me tell you that the first value 164.2 is telling us about the display size of a cell phone and in millimeters. Simply convert this value to inches then you will get to know what will be the display size of a cell phone. Secondly, the value 75.9 is telling us about the display width and the last value 9.1 is about cell phone slimness.
The majority of the people don’t understand and mostly ignore this portion while checking the specification of any smartphone. You will find different type of displays in smartphone which are as under:-
TFT LCD (Thin Film Transistor LCD)
This type of display is commonly used in low-budget smartphones. However, it breaks easily and it consumes more battery power. Moreover, this LCD color and contrast is not that much good therefore, avoid smartphones that contain this type of LCD.
IPS LCD (In Plane Switching LCD)
You will find this display in midrange price smart cell phones. These displays picture quality is best and it consumes low battery power. Moreover, its angle view is better, and if we press the screen so colors don’t spread like we have seen in older smartphones screen. Additionally, in sunlight its response is better.
OLED (Organic Light Emitting Diode)
This display also gives you better response time and it consumes less battery power compare to IPS LCD. But in sunlight its response is not that much good as compare to IPS LCD.
Amoled (Active Matrix OLED) and Super Amoled
This display is thin and gives a sharp image and its response time and contrast are also better. It consumes less battery power. Moreover, as compare with IPS LCD it is slim and flexible.
iPhone smartphones used this term, actually it is IPS LCD. Now many of us will be thinking that why Apple iPhone used that term for display. So, the short answer is that when apple used the term retina display that time their smartphone PPI (Pixels Per Inch) was higher as compared to other smartphones. Therefore, this was a marketing stunt from Apple, and nowadays every smartphone with PPI more than 300 are considered a retina display.
There are many processor manufacturers like Qualcomm snapdragon, MediaTek, Exynos, and HiSilicon. Now question arises which processor company is manufacturing the best chipset. Honestly, I can only tell you about 3 manufacturers Qualcomm, HiSilicon Kirin, and MediaTek which I experienced.
Qualcomm Snapdragon Processors
Qualcomm is an American company. In midrange price cell phones you will find Qualcomm Snapdragon 400 series chipset. As per my personal experience, my current smartphone chipset is Qualcomm Snapdragon 450. In addition to that this chipset is considered versatile because of stable performance.
HiSilicon Kirin Processors
HiSilicon is owned by Huawei and it’s located in China. In midrange price smartphones you will find HiSilicon 600 series chipset. My last smartphone was Huawei which was embedded with HiSilicon Kirin 620. Furthermore, I used that cell phone for more than 4 years. Performance-wise I never faced any problem.
MediaTek is a Taiwanese company. In midrange price smartphones you will find MediaTek A series, P series, and some G series chipsets. My first smartphone which I bought back in 2014 was embedded with a MediaTek processor. My experience was bad with this processor as I did face heating issues while playing games and also with excessive use I did notice heating issues. But MediaTek is improving the quality and you will find high-performance MediaTek chipsets in their high-tier smartphones.
Samsung introduced Exynos processors in their smartphones. In midrange Samsung smartphones this chipset can be used with 8nm and 10nm technology. People who are using smartphones with Exynos chipset are looking satisfied with the performance.
What is 7nm, 8nm, 10nm, 12nm, 14nm and so on
Short and sweet answer for this it’s a transistor size on the chipset. On chipsets, billions of transistors are responsible for the operation of the smartphone. Again question arises which value is better low value or high value i.e. 10nm or 12nm. Therefore, an easy way to understand is that low value is good. The smallest transistor size means low battery consumption and also you can say high speed. But there are other factors too which will define the high speed and high performance. Which are the numbers of transistors and number of cores and most importantly frequency.
CPU (Central Processing Unit)
While reading any smart cell phone specification you will notice the CPU section in which it will be written Quad Core or Octa Core 1.2 GHz or 1.8 GHz Cortex A53 or Cortex A55 and so on. Moreover, sometimes you will notice that if the CPU is Octa-Core so, the specification will be like this 4 x 2.3 GHz Cortex A73 + 4 x 1.7 GHz Cortex A53.
Therefore, let me explain to you about the above-mentioned things. First of all, Quad Core or Octa-Core means that either 4 cores are embedded in a chip or 8 cores embedded in a chip. Additionally, these cores operate according to the task which we perform on our smartphone. Further to that in Octa Core 4 cores are separated for high task while the other 4 cores are for general use.
Now talk about frequency so, high frequency means high speed and low frequency means low speed. For example, 2.3 GHz frequency is faster than 1.7 GHz. Whereas, an Octa-Core CPU mostly you will find two frequencies i.e. 4 x 2.3 GHz + 4 x 1.7 GHz which means that high-frequency cores are for big tasks on your smartphone while small frequency cores are for normal tasks on your phone.
I hope everything will be clear so, what is Cortex A53, A55 etc. So, long story short it’s an architecture designed by the ARM company. Companies like Qualcomm, Samsung and Huawei etc they develop their chips on the architecture designed by the ARM company. Now many of you will be asking which one is better let suppose A53 or A55 therefore, the short and sweet answer is higher the version so higher is the performance.
GPU (Graphics Processing Unit)
As we know from the name itself it deals with the images and animation on smartphones. If you want to know which GPU will be better for you then you can search it as honestly I didn’t do any research on it. Now many of us will be thinking that what is the difference between CPU and GPU. So, the CPU is the brain that will perform other tasks whereas, GPU will handle things related to images, video and animation etc.
Memory of Smart Cell Phone
Millions of times many of us heard that smart cell phones with higher RAM will be faster and performance will be better. But, in reality, this is not the case. First of all, we need to understand what is RAM and what is ROM and I will try to explain in a very easy and short way. RAM means Read Access Memory whereas ROM means Read-Only Memory.
For example, if you are using any application like Whatsapp or Facebook so these application files first will be stored in RAM. Furthermore, when you close these applications or smartphones switched off so their files will be removed from RAM. In ROM your files, applications are saved and in case of power failure i.e. smartphone switched off your data will be saved in ROM.
Talking about the speed of the smartphone you only cannot rely on RAM size. But if you are a gamer and like to play heavy games on your smartphone then yes you will select a high RAM smartphone. However, if you are a normal user of the smartphone then I think 2 GB RAM will be more than enough.
In any smartphone specification, you will find either a Lithium-Ion battery or Lithium Polymer battery. I think as a user you don’t need to confuse these things. Because at the end of the day your work will not be affected by this, however, yes there is a difference between these two types of batteries. Lithium-Ion battery is a little heavier than Lithium Polymer battery but Lithium-Ion is an old technology while Lithium Polymer is a new technology.
Moreover, Lithium Polymer is flexible and manufacturers can make these batteries in different shapes and sizes. Now you will think what is 3000 mAh and 5000 mAh so, these value depicts the capacity of the battery and more the value so more backup time of the smartphone.
Still many of us will be confused and thinking and which smartphone should they buy? The answer is very simple first do your self-assessment and ask only one question from your self and it’s “For what purpose I am buying the smartphone?” If let suppose you are a normal user and only use Whatsapp, Facebook, and youtube. In addition to that then you can simply buy a smartphone in midrange with 2/3 GB RAM, 32/64 GB ROM, and a 1.2 / 1.8 GHz Octa-Core processor. However, in chipset, I will recommend either Qualcomm Snapdragon or HiSilicon.
