Let’s face it guys, money matters. It doesn’t matter how much of a posh phone you want, you have to have the ability to buy it.  But then again, you can’t buy a so-called smartphone. So you have to write down your budget and surf the features of the phone on the internet. When you will know the features you want, fits your budget on a phone, then buy it as soon as you can. There are now lots of mid-range phones who are offering satisfying quality. All you need to do is, keep an eye on the hit list. So before buying a new mobile, must be fixed your budget first.

Operating System (OS)

Choosing an operating system is a must when it comes to buying a phone. The fight of iOS and Android has been lasting till today for a long time. Android gives you the option to customize your phone easily. Besides, it gives you the chance of choosing between hundreds of brands. However, Android updates can only be available for some selected brands like Google, OnePlus. Some brands are there who supports the Android One like Xiaomi Mi A1, Infinix Note 5 and the new Nokia Phones.

On the other hand, Apple iOS makes sure you can use your phone easily. Jumping from one app to another, starting and quitting an app will give you an amazing comfort zone. Using an Apple iOS also gives you the opportunity to have a well-curated app store.

Unlike Android, all the updates of iOS are instantly available all through the range. They also allow easy syncing between all Apple products. In addition to these, if you want to have a laugh at your friends who have OTHER operating systems, you can always do that while showing off with your iPhone. But hey, DON’T BE MEAN.


Choosing the correct brand is a MUST while you want to buy a phone. If you do your research, you’ll see there are tons and tons of brands of phones but only a few of them are in the top chart.
Now I don’t have to introduce giants like Samsung Bangladesh, Huawei Bangladesh, Xiaomi Bangladesh, Apple, and others. All of these brands have their influence in Bangladesh. All of these brands have their own uniqueness and innovations. However, you will always have to choose your own preferences.

You can search what’s on Top. You can collect information from the internet or can ask your friends which brand they prefer. Obviously, the reason a brand gets on top because of its innovative qualities, right?? So it won’t be a problem to know which brand got its Brand Loyalty.


One of the most important thing which we personally think is the Camera. In Bangladesh, you will see the majority loves photography. To be honest, who doesn’t?  We all know that there are 7.6 billion people in the world. Now let us share some fun facts which may help you up to gather some information. Starting from 2010, until now, 40 Billion photos have been shared on Instagram.

‘My Camera has better Pixel than yours.’ This is a lame term, to be honest. You might see your friends are always bragging about their photo pixels once in a while. Honestly, having a Camera with greater Pixels does not mean, the Camera is good. The Quality of a camera of a smartphone depends on certain factors. It depends on camera aperture, pixel size, ISO level, autofocus, and many more other factors.  So, do not get fooled by megapixel issues. The quality of the lens is what that actually matters. You might get surprised to learn that a 15MP rear Camera does not necessarily be better than a camera which is 12MP. We can apply the same theory for the front-facing cameras as well.

Basically, a higher number of pixels make sure the size of the image is bigger. Which means, when you see the photos captured by a high pixel camera, it will become sharper once you see this photo in a small screen. Do not get yourself fooled by the sample photos provided BY THE MANUFACTURERS.  Huawei has been caught twice when it used professional quality photos caught by DSLR camera and then claimed that this photo is from their own flagship smartphones.


Look for random reviews on the internet about the camera qualities. You can go and see people posting their photos, photos of dogs and cats, photos of bananas, foods etc. Try to compare which quality fits you.

If you want our opinion, we will say, Google Pixel still takes some of the coolest and best photos. You can also try new the new Samsung s10 series. You can also go for the new Huawei Mate 20 RS Porsche design, which is one of the PREMIUM VERSION phones of Huawei combined with Porsche.

Close competitors of these phones can be the new iPhone X as well as the Huawei P20 Pro.  If you want to go for a budget device, you can switch to Motorola G6 for great photos. A person who loves photography might want to go for a camera with 12 or 16MP sensor that lies under  f/2.0 or lower aperture. He may want this for speedy shots even when he is under in low lights. On the other hand, a casual photographer can do the job even within an 8MP or 12MP camera that lies under f/2.0-f/2.2 aperture.


Researches show that about 40 percent of people use their phones when they are in the toilet. They send emails, watch cat fail videos and surf through Instagram to watch celebrity lifestyles. This adds up heavy users who cannot live a moment without their device. A huge portion of this group loves to watch tons of videos. This shows their love for big size screens. The size and the resolution of the display of your phone actually depend on how you use your smartphone. If you are a person who loves to stream videos, edit pictures and videos or download and watch movies, then a 5.5 inch to 6 inches, full HD or HD+ resolution phone should be enough for you.

If you want to go for a larger phone which is more than 6.4-inch display, it will make the handset extra bulky. Plus, you won’t have the ‘good handling’ feel anymore. In addition to that, high-resolution display basically eats up lots of battery charge. So if you want to kill your time with watching movies as well as you want a big display, we suggest you connect your charger all the time with your phone. When you are looking for a phone with the best display possible, you might want to check out the contrast, the color, and the brightness but you don’t want a great pixel density.

You will notice if your phone is not bright enough to read outside or if you get ugly colors from it. However, you might not notice a huge difference between 1080 Pixels and 4k videos. With that mind, you should generally try to look for Pixel Density of around 400PPI. Pixel Density isn’t generally that important unless you have a Virtual Reality headset or have amazing vision inside your eyes.


Now if you are a guy who’s living his life to the fullest, have wife and kids along with pets, then trust me, you need REALLY BIG STORAGE.

Why? Come on man, you will need to take lots of pictures and videos of your moments. And for this reason, you also will need lots of storage to store your things. If you have a phone with storage more than 32GB, you will have a bad time. Yes, it doesn’t even matter if you own an iOS or Android device. Especially, many phones do not even come with an extra storage system. Even is some do, that won’t guarantee you that you’ll be able to use your SD card for apps.

If you have a storage of 16GB or less, you will have to keep in your mind that the operating systems also take up space. SD cards are great for photos and music if you download them. However, when apps are concerned, they are only good for Android 6.0 and up.  If you still think, you will survive with 16GB and cloud storage, we will say you are right, but it will also give you a bad experience as well.

So what do you need to do???
You need to go for 64GB and 128GB of storage so that you don’t face any bad experience with storage. We saw lots of people deleting their favorite photos, videos, apps, just because they struggle with storage. As for RAM, 3/4GB is a great place to start.  The more RAM you have, the better multi-tasking experience you’ll face. It also means you can open more apps all at once.


We all had those moments when we were watching our favorite movies, or we’re in the middle of a game, the battery dies. So to escape this bad moment, you need to make sure you have the battery life you need. Now there are certain people who don’t mind charging their often but others do have high expectations. You need to keep in mind that a BIGGER battery doesn’t always mean better endurance. If an Android phone has a 4000 mAh powerpack, it will probably last for ages. But usually, phones have less power than that because they are quite bulky. If you are a heavy user, and work on apps, games, or watch videos, then you will need at least a 3500 mAh battery or above. However, if you are just an average user, a handset with a 3000mAh battery will be quite enough for you for a full day.

There are two things you really need to care about. The first is the Screen on Time. This is how quickly the battery dies when you are actively using the phone.  Now this will depend on person to person as everyone uses their phones differently. The other thing you need to look into is the total battery life.  This will give you an idea of how long the phone will last with average use. We are not saying you will always have to rely on these, but these two factors will give you an idea about the battery life.


The processors of a smartphone vary from one another which depends on some factors such as OS version, UI, bloatware and more.

If you are a heavy user who spends his time editing images/videos/documents online, play games, stream videos then you should go with smartphones with Qualcomm Snapdragon, MediaTek or Hiilicon Kirin latest chipset. The best thing about Qualcomm Snapdragon is that they come at an affordable price. This will also allow you to multi-task with ease and comfort. Processor plays the major fact for your mobile performance. So before purchasing a new mobile, you must consider the latest mobile processor.


If you rely on heavy video streaming and video conferences, speakers and quality of audio that comes from your phone will be an important issue for you. If you like entertainment, then it is better for you to buy a handset that has front-facing speakers. This will give you clear sound even while you’re holding your smartphone in the landscape mode. If you are not into video streaming or video conferencing much, then a regular handset that has bottom-firing speakers should be enough for you.  The phones that have speakers placed at their backs are fine as well.

People in Bangladesh, often tend to show less concern with USB Connection, but ports too can be a factor to consider. Though, both micro-USB and USB Type-C are quite available all over the market, we recommend you to switch to Type-C. It is not only just easy to use but also, we think in the future all the ports will come as USB Type-C as its fame is reaching its peak. All the new phones these days are coming with Type-C ports. Few phones have already stopped using the 3.5 mm headphone jacks as well. But we expect that it will still take at least two more years until all the OEMs completely switch to USB Type-C.


We already said goodbye to all those days when you could only play games only on your PC. As AI systems are getting stronger, smartphones are coming with heavy GPU which lets everyone to play heavy games. GPU basically makes sure you get to play your desirable games. But the more graphics hungry the game is, the more GPU you should need. It is also needed for having the best quality video experiences. PowerVrGT7XT is the fastest GPU series for smartphones according to our opinion. It is used by many Apple products like iPad Air 2, A9 SoC chipset etc.

This GPU that is made up of 14nm/16nm technology will give you the best gaming experience. You can also look for smartphones that use Qualcomm Adreno 540. This latest beast comes with Snapdragon 835 Chipset which is made for smartphones.  This is perfect for you if you use mobile VR, love 3D gaming and watch 4k videos.

Almost all smartphones these days have extra features such as reverse wireless charging, fast charging, Accelerometer, Gyro, Proximity, compass, barometer, fingerprint sensor, iris sensor, face-unlock etc. These are not only used for locking or unlocking but also as passwords to access files documents and apps. You can find smartphones with fingerprint sensors in Bangladesh if you have a BDT 10,000 budget. But we recommend you to go for a bit higher price and buy smartphones with extra-security features since we care for your personal stuff to stay personal.


New phones are now coming with extra innovative features. The revolution of smartphones is changing fast. Since TechT20 team cares for Bangladeshi smartphone users to have the best knowledge on phones, we have set this article, keeping in our mind about the mindset of Bangladeshi people.

These are the things (which we discussed) Bangladeshi smartphone buyers are concerned with when it comes to buying a smartphone. But then again, tastes may differ. You can always let us know what you think about our article and which information you are still seeking.
