How do you select a perfect Smartphone?

Although we are smart enough to understand our needs and therefore we look at the reviews to know the specifications and compare one to compare each other. But our country's online market is not so famous that most of the smartphones are sold off the offline market. In that case, if you are a general buyer then the shopkeeper will encourage and sell you some other times. In that case, the shopkeeper thinks about his profit, not about your requirement.

So today I'm going to give you some tips or guidelines to buy a smartphone through which you can easily and quickly review your phone. And you can buy the phone as well as the most suitable for you in your budget. Start review

Operating System

Three types of operating systems are available mainly in the market: Android, Windows and iOS. The Windows operating system is used primarily in Nokia and Microsoft phones. Also, many Chinese brands also use this operating system. Apple only uses the iOS operating system for its iPhone because it has its own operating system and maybe they do not want any other company to use this operating system. An Android is a very famous operating system.So many branded companies, as well as the general company, are using the Android operating system.

Windows OS

Now the question is what operating system will you choose for your phone. This decision depends on your budget, your choice and obviously your purpose of using the phone. In this case, I would suggest that the Android operating system is the best for you. But if you're bored using Android Phone or you have a problem using it then you can try Windows Phone.Windows phones come with a completely different interface than the Android operating system, and this is Windows PC. Seems quite easy to do. Users, and this feature will appeal to you.

But as a user, I am not satisfied with Windows Phone because it deprives you from the freshness of using the smartphone. In fact, Windows Phone is not right for hard users because this operating system is very close and you can not make any advanced use with the phone, and this phone also has a lot of problems, so that you can always have your favorite app or game Can not use or software with this OS Actually, Microsoft is not so disturbed with its phone platform.So in one word, I can tell you that if you use so many phones and want to try something new now you can try Windows Phone.

Apple’s iOS

As you all know, the most important thing is to use iOS or Apple I-Phone. So if you have enough money you can easily buy I-Phone because Apple is always best for their product quality and customer support. And whenever you buy an iPhone it is better to buy the latest model. Many of us buy old models only to buy the logo.

Your money is worth so if you buy iPhone IV or iPhone V, then you are wrong because they are very good in their time but standing in 2017 they are too old to use. So it is better to buy an Android phone instead of buying an earlier version of the I-Phone in rupees. 20,000 to get better value for your money. And there is nothing to say about the configuration of the iPhone because in the latest iPhone, they always use the latest hardware for customer satisfaction.

Android OS

Let's talk about Android phones. To buy an Android phone, you have to see a lot of issues. However, Google is the owner of the software, but there are many companies who have the license to use this operating system. You can find an Android phone from low budget to high budget in the market. So now we finish discussions about Windows and iOS and share tips for buying a good Android smartphone.

You may like Android OS, but there are many versions of it. It's better to choose the latest Android version at the time of purchase of the phone. If the latest version is not possible, go for the first one before the latest version. The latest version is Andriod 9.0, although very few models use this version. So Android 6.0 or Marshmallo should be the best option now because Lollipop or KitKat is now backdated for a long time.

There are some good sides to use the latest version because the app developer has developed and updated its app based on the new operating system, on the other hand, the new operating system is also quite secure. Since hackers take some time to find a weak point, they do not get any weak points so fast for the latest operating system. Now one day in the most newly released phones, Android 6.0 version is used, even phones with many low budgets are also using the Android 6.0 version.


Processors are important tools for any computing device especially for smartphones. The main features of your phone will be mainly good or bad, it mainly depends on the processor. If you are going to buy a high budget phone, you will have to look for the most recent processor because the latest processors will deliver the best performance and will also consume less power. Now one day Qualcomm snapdragon 855, 845, 821, 820, 810, 652, 650; For Samsung Exynos 8890, MediaTek Helio X20, X25 p60 etc. are very good processors. So you should have one of these processors to buy a good phone. Each company has different features for different processors, so you have to select the latest. Even you can get the latest smartphone processor. just "Google" it.


For mid-budget phones, you also get some of the latest processors, even if you have not much money. You can also get the latest processor for the phone. Range of 15-20 thousand. Snapdragon 425 to 636 or helio p60 processor is usually used for low budget phones. The other two main features of the processor are frequency (its function capability; indicated by GHZ or GigHartz) and core. By the core, you can say more hands, this means that the more you have the processor, the more core the processor will be faster and your phone will be very smooth.

In the current market, you can see 8/10 core processors from 4 core. But the core count does not always give better performance, because for better performance, you should have better RAM and higher battery performance, although you control the performance of your processor by overclock or under clock clock. Depending on the core of the processor, your phone gets more heat because more cores do more processing and generate more heat. So you see that problem too Without it, there are many reasons for heating the smartphone.

Clock Speed

A clock is applied to the processor, which shows how much processor works in a second. You can get speed processor from 1GHZ to 1.3, 1.5, 2.0, 3.0 etc in the market. In this case, too much speed is better, but for greater speed, you need more battery power. And the processor industry is also monitoring it. So if they have created 8 core processors then 4 cores are of high frequency and 4 core are low frequency because lower frequency core protects battery life and high frequency core works at the time of display.


Smartphone has another term with a CPU called GPU or Graphics Processing Unit. Although the processor handles all the things in the phone, but graphics, gaming performance, and frames per second are managed by the GPU. So with a good CPU, you also need a good GPU for your phone. So confirm that the phone also has a good GPU. Click on "Latest smartphone GPU" on Google to find the latest GPU catalog.

Now a days, the latest series of Adreno 530, Mali-T880 and Pavrova is much better. And you get a lot of ideas from Google. You need to look at the GPU to buy a Smart Budget of a High Budget or Medium Budget because you can not set a dedicated GPU later like your PC. It seems that those who like to gamble on the phone will have to find a good GPU on their phone. Although you do not have to worry about low budget phones, but it is always good to choose the latest GPU. To learn more about GPU, please go through the article bellow.


You can go through a dedicated article of RAM to learn about RAM. RAM is a part of your phone that helps the processor to process or run any application on the phone. The PC RAM and your Smartphone RAM are doing the same thing in the same process. At present, 2 GB RAM is very essential for any phone.

If you have 2GB RAM then you can not use it completely because the operating system or the different internal process uses half of the RAM. It may be that your total RAM is reserved by 800MB or 1GB operating system. Now a days in the 15-20 thousand rupees, you can see 3GB or 4GB RAM and some phones are also 6-8 GB of RAM. Now one day it's okay for 2 GB RAM on your phone, but if you have 3-4 GB RAM then you can use them for 1-2 years. However, you do not need more than 6-8GB of RAM on your phone. If you have a low budget phone then it has minimum 2GB RAM which is available from 4 to 5 thousand rupees. But buying a phone with 512MB or 1 GB RAM is a silly thing.

If you want to multitasking then more RAM is required. But we do not do such multi-tasking in a phone. At one time we browse the internet, check emails, work on Facebook Messenger and play music and at the same time doing all the work is enough to do 2GB RAM. So the only option is to have 2 GB RAM or higher.


Smartphone display is a part in which we spend more of the day. We need a good quality display that has a good color resolution and a wide viewing angle with a good quality phone '. So you can go through the article on the smartphone which has been discussed earlier. Now the super AMOLED display is the best and it is used by different companies like Samsung and others.

If you have decided to buy a good phone, please confirm that it has a super AMOLED display. After that AMOLED display and LED display. You can get a Super AMOLED display in the mid-budget or AMOLED display phone. In the low budget phone, you have to like for LED display. Now there are some phones using LCD panel display and it is better to avoid them.


In the display, you have to show two more things: one is the display resolution and the second is pixels per inch or PPI. For the current demand, your display resolution should be HD (720p or 1280 x720) or it would be much better if it was full HD (1080p or 1920x1080) Without it, you can not get a 4K resolution display phone in the market. For normal use, full HD display is good but it is better to use 2K or 4K display to enjoy VR (virtual reality). Now a day you can also find HD resolution display in mid and low budget phones.


Every display is made of lakhs of dots, which is called pixel. HD display has 1280 pixels horizontally and 720 pixels are perpendicular. There is a total of 1 million pixels. Now your display can be of 6 inches or 5 inches or 5.5 inches can be all HD. Whatever your size of the display, the total number of pixels is 1 million. The total number of pixels in one inch is called pixel per inch or PPI. There is another article on PPI. You can go through it for information. More PPI word display is better, though it is not always true. This means that there should be an adjustment between display size and PPI. And 350-400 ppi is better for every screen.

Display Size

Now I talk about the size of the display. It depends entirely on your choice. Some people choose a small screen and prefer a bigger screen. According to me, it is better to have a 5-inch display but you can take a smaller or larger display as per your choice. And in the time of choosing a larger display, you also see the resolution. If you have a 5-inch HD display then it is okay, but if it's 5.5 inches or 6 inches then its full HD should be otherwise it looks hollow. Then if you choose a small display with 4K, then this is also not profitable because you do not keep any differences in it. I recommend you 5.5 inches, which is the owner of big hands and people with little hands 4.7 - 5 inches.


Once there was a huge demand for any camera phone but it was 8-10 years ago. Nowadays, many powerful cameras are used in smart phones. Starting from 5 MP  to 20 MP or more in some phones. However, the mega pixel is not the whole thing, except that the quality of a camera also depends on the camera sensor, image processor, aperture, lens, etc.

Now one day 13-20 MP camera has been used in high budget phones. So please take a closer look at the lens, camera aperture, image processing software etc. Now one day many dual cameras are used in many phones and this is really good so you can buy one of them. And if you want to purchase a low budget phone then its camera should be 5 MPs, especially the front camera should be good so that you can do video chat very well.


There is also a variety of batteries for smartphones like RAM, processor and display. And a perfect configuration requires a lot of perfect battery. Now for smart phones 4000 to 6000 mAH is used. The higher the battery mAH, the higher the phone battery backup. If your processor is powerful and has many cores in it, its battery should also be powerful. Your phone should have a minimum 3000 mAH battery and it is better to have a battery of 4000-4500 mAh or more powerful.

Many of us think that the battery is removable or non-removable. Many times we reject the phone only for non-removing batteries because it is according to our liking. We do this for some wrong information and wrong thinking. Many of us think that they may have to face problems when the phone hangs out and if they are damaged, then do not change the battery. It's all wrong because you can reboot your phone very easily when it is hanging and its battery also changes with care. And I think the non-deleting battery is best to get the premium to feel on your phone.

You do not need a headache if your phone's battery is of lithium-polymers or lithium-ion because both are very good and you can count on one of them. Please see the article on lithium-ion technology for lithium-polymers and batteries for further details.

It is better to have Quick Charging technology in your High or Mid Budget phone because it takes the necessary charge in a very short time. Sometimes it becomes a life saver for your phone. If you are a technology lover then you can choose a wireless charging phone.

Chinese brand or traditional brand?

This is a million dollar question for a high budget or moderate budget smartphone buyer whether they choose Chinese brands or traditional brands. If you want to show to your friends, then you can choose Samsung or Apple, otherwise, if you want the right value of your money, then you can choose any Chinese brand or traditional band phone according to your budget.

Chinese brands such as Xiaomi, OnePlus, Honor, Huawei etc. are many good quality phone suppliers. They have so many phones ranging from low range to high range which are very good and durable. And according to my personal experience, the mid-budget Samsung phone is not a good option, but you get all the necessary features from the Chinese brand. If you want to know the reason why the Chinese phone is so cheap then you can go through the article posted on it.
