10 Things to Consider Before Buying a Smartphone

Buying a smartphone is quite a hassle and due to the advent of operating systems such as ios, windows, and android, we end up in confusion about what should we buy and what might turn up the wrong decisions or bad taste in the mouth.

Since 2012, I am buying smartphones those offers better value over time. Initially, I was not aware of these things and ended up buying smartphones just because of their looks and brand value. After a few mistakes, I started researching about phones and this guide will provide you the basic knowledge about smartphones if you understand it properly then you will be able to tell which smartphone is better than the other.

Specifications tell a lot about smartphones and end-user get a much better hold over the technology if one has a basic understanding of various parts and technology used in phones.

Things to consider while buying phone

This guide is not an advanced guide so anyone who can understand English and remember a few new terms will have no difficulty buying the next Smartphone. This guide is just about the internal hardware of a smartphone so do not judge if the smartphone looks cool but fails in this specification test.

Let’s have a look at these 10 factors below you should consider before purchasing a Smartphone-

1. Processor

It is a vital component of your smartphone and just knowing about the cores of the processor is immature behavior. You should have basic knowledge about it like the company who made it such as snapdragon and MediaTek. Clock speed and process by which it is made. Whether the processor is of flagship grade or not.

These factors will help you buy a smartphone with good support from applications. In other words, smartphones won’t hang by applications in their later year. This is one of the common reasons why Apple iPhones do not crash and get slow down.

If you are buying a smartphone and want to know more about processors, then here are some tips –

Look into Snapdragon or MediaTek’s website with the model number of your processor and check respective websites. There are Wikipedia articles about most of the processors but they might be confusing for beginners.

Here is the quick overview

SnapDragon Processors

  1. Snapdragon 200 series– lowest-end processor (good for low memory games, browsing the internet, and regular social media applications), it usually lasts for two years after it might not be as snappy for the basic applications. If you are a gamer or an advanced user then you should not go for it. The best deal for a smartphone having this processor is between 4000-7000 INR.
  2. Snapdragon 400 series – It is the best processor for entry-level smartphones as it provides better value in terms of performance and gaming experience. You will get support from applications as it is a very popular series of processors. It is a highly recommended series, many high-end smartphones are going for it.
  3. The best deal for this series is between 6000-12000 INR. Exceptional case: If you are happy with the looks and other features of your desired phone but the price is higher to the point of 19999 INR then you can go for it.
  4. Snapdragon 600 series – It is quite an unusual series. Processors in this series were used to come into flagship series smartphones such as Samsung s3, note, HTC flagships, and other initial androids. Now it is the second most important series of processors. Usually, these are more powerful, performing, and efficient than the 400 series. There are few processors in this series(625, 626, 630, and 660) built with a 14nm finFET manufacturing process, which in laymen’s terms makes these two processors superior to their counterparts by improving power efficiency.
  5. Snapdragon 800 series – It is a flagship series made by snapdragon, at present all android flagships have a snapdragon 800 series chip inside them. They provide the best and latest features inside them. If your smartphone has a chip from this series then you don’t need to look twice over it unless the chip is ‘810’, which has been a disaster as it has severe heating-related issues. For others, you don’t need to think too much. If you want best-in-class gaming, virtual reality support, and other cutthroat features then go for the latest and cheapest smartphone that has a snapdragon 800 series chip. Recently snapdragon 820,821 and 835 were so good that they even managed to get ahead of the latest apple chips.

MediaTek Chips

I myself generally ignore Mediatek chips as they tend to overheat or simply don’t have application support to them. Cheap smartphones usually from Indian or Chinese smartphone manufacturers use them. They do have some good chips too such as the Helio x and p series.

If you are confused between Snapdragon400 or helio chips, then you should go for the Mediatek chip, because performance is better in Mediatek chips compared to snapdragon low end chips. You won’t get extreme battery life because they have many cores such as quad, Hexa, Octa and Deca cores.

More cores usually have many drawbacks like they consume more power and produce heat, and single cores are weak so the phone might hang or lag for games and graphics-intensive applications. The only thing that’s better with more cores is multi-tasking. So when we sum it up, we should avoid mediating generally but if your beloved smartphone has an Helio chip rather than a regular Mediatek then there are fewer things to worry about.

Exynos (Samsung Chip), Kirin(Hisilicon chips)

Exynos has been a good alternative to snapdragon chips as they are quite good for daily tasks, do not have heating issues, and provide good performance as well. The only drawback is the lack of support by developers in general. HiSilicon kirin’s line is quite impressive and similar to Samsung Exynos. Kirin chips are also very power and performance friendly. Recently they are making chips specifically for some models(p10, mate9) and applications (pokemon go).

Intel Atoms and Other

Only a few smartphones have these chips and usually, they aren’t received well such zenfone c(intel atoms), mi pad 2, etc. they have heating issues as well but the most important problem might be the lack of advanced features as well as applications might hang up on them. Tigra chips and Nvidia chips are examples of the wrong implementation of chips in phones. Only a handful of smartphone OEMs use such chips. Recently MI also launched the surge s1 processor.

2. Ram

Just check whether it is DDR3 or later. More the number is better is the deal. But you don’t need a ton of ram for your smartphone. More ram means you will get better at multitasking.

3. Display

There are a number of Factors you should look for such as

Type of display

  1. LCD panel – Most common type in the cheap smartphones, consumes more battery and might have a yellowish hue in it. According to me, you should not go for it.
  2. IPS panel – Most smartphones, laptops, and tv these days have IPS panels in them. The reason is quite simple. They produce excellent colors. Don’t think too much if the smartphone you are purchasing has IPS technology behind it.
  3. AMOLED panel – This is the most power-efficient panel in the market today. Not many smartphones have it and the reason is that they are quite expensive and made by only one company named Samsung. I am not a Samsung fan but truth is that these panels produce perfect black color by turning off pixels to save power, and contrast levels are perfect. They might have some kind of primary color (RGB) hue in them. But their overall performance is perfect.

Pixel Density

It is a number that defines the sharpness o the display. In layman’s terms, if a smartphone has a pixel density of more than 270. Then it will look like paper to the human eye. You won’t be able to notice grids or black lines if the pixel density is good. In an expensive or good smartphone, pixel density is more than 400.


There are 4 types of resolutions

  1. SD – a standard definition where picture quality is just ok. It is the basic resolution where everything is good enough for us, going lower than that you won’t be able to enjoy your content properly.
  2. HD or 720p – high definition is just more pixels. More pixels simply mean a better experience.
  3. Full HD or 1080p or beyond it are just numbers as your human is not capable beyond it.
  4. Quad HD and so on they are just numbers.


It is a personal preference and keeps on changing. Nowadays bezels the black area around your screen) are reduced so much that even 5.7 inches can be compact. Consider the screen-to-body ratio if are buying your smartphone online. High the body ratio, the better will be the deal.


Just check the highest brightness that can be achieved by your smartphone. It is measured in nits. More nits will help you see pictures on display under direct sunlight. 400nits is a good number as a reference.

Viewing angles

Make sure it is more than 120.

Screen protection

Gorilla glass is good but not perfect so keep a tempered glass or some sort of lamination over your smartphone.

4. Sensors

Few sensors are very important for your smartphones other doesn’t matter a lot.

Important sensors – ambient light sensor, accelerometer, proximity, gyroscope, and magnetometer.

Useful but less important – barometer, heart rate sensor, pedometer, infrared, ois and eis, fingerprint reader, additional noise cancellation microphones, etc.

5. Battery

It depends and there is not much choice here as more than 98% of batteries are lithium based either ion or poly. The amount of battery required by you depends upon the screen size, type, and processor you have. iPhones have less amount of battery but offer a good screen on time because of the superior software and processor they use. The same thing is true if your phone has a good processor and good software.

2 more things related to the battery should be considered while researching about your phone.

1st is charging speed because a fast charger might help to get more juice in a couple of minutes, it’s quite handy stuff and useful too. There is different kind of fast charging technology available today and everything works just fine for example Oneplus have a dash charger, and Samsung has Qualcomm-based fast charging.

2nd is if the battery is removable or not. A removable battery is easy is replace so keep that in mind, but not many good smartphones have a removable battery. So if you find a removable battery in a smartphone you like then consider yourself lucky.

6. Speakers

Speakers should be loud but with a good base. Call quality and media experience are improved very much with boom sound or stereo speakers. There are two major points here-

1st is the placement of speakers– if speakers are front facing then you will get the best media experience. HTC, Motorola, Sony, ZTE, and Lenovo are some companies that make smartphones with front speakers. Then there are phones with a bottom speaker. Good but not ideal as you might accidentally block them and most of these speakers are mono speakers. These speakers are not very loud either. They are still better than back-side speakers. If smartphone makers don’t care about media experience they put the speaker on the backside just for the convenience of the manufacturing process. There are common in entry and mid-range smartphones.

2nd is headphone or charging port – The headphone jack is a good option for hearing good quality audio, and I am not a fan of ditching it for the sack of less port or superior quality audio.

7. Camera

You must check reviews for it as it does not make much sense to argue about which smartphone cameras are better. There are tons of sensors in the market and the algorithm made by the software team decides whether picture quality is good or not. I would say Do not go after numbers. Check samples rather than specifications.

8. Bands

Check bands in case you are importing a smartphone otherwise don’t waste time over it.

9. Software and Updates

This is completely based on the history of smartphone makers, and something that you won’t be able to judge properly. Here are some references – Google updates its smartphones over a span of 3 years. Samsung about 1.5-2 years(if flagship then few more months), Chinese smartphones makers such as Oppo, Xiaomi, Vivo, Lenovo, Gionee, etc. – only once and then they will update their respective skins such as miui, color os, emui, flame os, zui, etc. Apple is the undisputed king here because it is the only smartphone maker that supports its smartphone software for more than 3 years.

In the case of android if are an advanced user or tinkerer like me check custom ROMs that are available for your smartphones in xda, miui, Lenovo, leeco, Oppo, and other forums in case you do not want outdated software. For noobs, I have a suggestion that if you can understand English well and have a PC then learn a little bit about custom ROMs as they are quite easy to use and also keeps your smartphone updated for a longer time.

10. Price

Try to buy online but beware of a few drawbacks as well. According to my own experience, there are few companies especially Chinese which offer great value for money doesn’t care about after-sale services. Here are a few good companies –

  • Lenovo ( good value for money but software experience is poor),
  • Xiaomi (provide only entry-value smartphones with less structural integrity but overall value for money deals),
  • Leeco (initially they were aggressive in pricing in India but now they lost their business so no service support),
  • HTC ( if you want to waste your money then go for it), Motorola (same as its parent company Lenovo, provide better custom ROMs),
  • Samsung (you won’t get sensors in their entry-level smartphones and mid-range in little expensive considering specifications), Apple(iPhones retain their value for a longer time),
  • Oppo and Vivo(parent company is same, I have one suggestion about them – just don’t buy them),
  • Micromax and other Indian brands(there is no sense in purchasing them as they import smartphones and don’t even work over software, even if you think like you doing some favor to India by buying them just open your eyes and do not fool yourself from latest creo to late Micromax not even one smartphone makes sense to me), there are few other brands but they are making any mark out there.

So this was all for now. This guide is written to get an understanding of the specifications of a Smartphone before purchasing it. If you have any queries then comment.

  1. What about oneplus brand?
    I’m thinking of buying the oneplus 5 when it releases.
    Can i get your opinion on that.

    1. Oneplus 5 is a good option if you want stock experience but recently their prices have been increased due to advertising and celebrity endorsement. So you may end up in paying a little bit more than usual this time. As far as hardware is concerned rumors and online pictures suggests that you will get snapdragon 835, dual camera set up on rear side. A quad hd panel on the front. Design might not be as refreshing as samsung s8’s bezeless design, and fast charging will be the same as in oneplus 3., And 3t.
      Software is still improving and they experimenting with it. Recently many users have complained about bugs in new updates. So be aware of that. Oxygen OS (oneplus own user interface) does have a stock feel to it, but things I noticed were that it doesn’t stand out of the crowd because customization are minimum at present and in case you lost your smartphone oxygen os doesn’t provide you system level protection.
      Conclusion : if you want stock experience with latest and flagship specifications than you should buy it. There is one more advantage of buying a oneplus is that you don’t have to worry about price drops. Main competition for this phone is mi 6(which may not launch in India), Samsung s8 ( very good option if you liked Samsung smartphone in the past), iPhone 7( if you want compact smartphone and like ios experience), oppo r11( you have to wait for it, and in my opinion, try to avoid it), lenovo z2 play( less powerful CPU but good for day to day tasks), huawei honor 9( you can go for it but it’s release date is not clear , it will be strong contender).
