Main factors to consider before buying a Smartphone[Special Focus; developing countries]

The mobile home in this generation has become an indispensable phenomenon. It will be so boring talking about the usefulness of a smartphone in our everyday life. We all know that there are no single criteria of choosing a mobile phone. In my article of today, I will be discussing strictly the factors you ought to consider before buying a mobile phone. Many people buy a phone that does not give them the desired utility. I will sub-divided this post into two, the first will be more beneficial to developing countries and countries with adverse climatic conditions and natural disasters.

how to choose yours smartphones


The whole factors border on one main central theme “what do I want from a phone”. My response will revolve around the above-mentioned theme.

  1. WHAT KIND OF JOB DO YOU DO: In Africa, we have the most strenuous jobs which are also being carried out in a harsh environment. So are factory workers, carpenters, manual borehole drillers, mechanics mention but a few. If you do a job that constantly requires throwing, lifting or jumping or any action that shakes your body vigorously. I have just two advice for you;1. it is either you purchase a rugged phone with the cheapest price possible(e.g Nokia Asha series) or 2. only access your phone when you are done with the day’s job
  2. WHETHER AND CLIMATE: I will focus on two weather extremes; rain and sunshine. In Nigeria for example, we have extreme heat in the northern region while in some part of cross rivers / akwa ibom states, you witness incessant rainfall. The same thing applies to some asian countries. Also, if you love swimming pools or the beach, you fall under the rainfall category same as someone who always stay inside the sun falls within the hot weather.  If you shall be encountering water or rain unavoidably and you want your phone to last long, please buy a good brand-name water resistant phone(some of them includes galaxy s5, s7, sony Xperia 2 till date, iPhone 7 and anyone of your choice. On the other hand, if you work in extreme heat and you do not want your phone to explode, buy a phone without no known temperature issues. please avoid samsung galaxy s6, note 7 or any other phone with confirmed high temp issue. Your surest bet on this is any good iPhone. If you must buy and android, please whenever you are working under high temp, off your data, off your Bluetooth, don’t play hd games, don’t play hd videos.
  3. CONSIDER THE BUILT QUALITY OF THE PHONE: This is also very important especially for those of us who are careless about handling our phones. Go for an armored-tank link kind of a phone as against a phone that is built like a toy. A good example of an expensive phone built like a toy is samsung galaxy s,s2, s3, s5 and s5. aAnother good example of a phone built with high quality materials are all iPhone(except 3g,3gs , 4, 4s), 98% of all htc phones, Virtually all sony phone. In fact merely looking and a well-built phone, you will know. I also prefer anodised aluminium body to glass body. when both are dropped, the impact is felt more on glass. A well-built phone must be firm and compact all round. it must not be loose.
  4. BATTERY CAPACITY: In  fact the longer your phone can stay on a single charge in Africa(especially Nigeria) the better for you. This is because of the erratic and unstable power supply. Please thsi is one of the most important prerequisites.
  5. FULLY UNLOCKED: This is more apparent when you buy a foreign-used phone. Before bringing it to Africa, please ask the seller /giver to help you perform a full carrier-unlock on it. It should not be selective of local sim card. Now i will go over


We are still on the theme “what will I be using my phone primarily for?” just that this time around, we are talking about the general factors that should guide you before buying a phone. Be it used or new I will dedicate another article for specific factors affecting the purchase of a used phone.

  1. To start with, before venturing into buying any phone, visit reputable phone review websites like “” or to acquaint yourself with the features and the specifications of the phone you have in mind. Am afraid you won’t see knock off phones here. You will see only brand-name phones.
  2. Are you buying the phone for your Image and or Brand? :  Have you ever wondered why all our celebrities opt for the latest mobile phones from the most popular manufacturers in the world? Well, even a politician that does not know more than to make and receive calls will surely buy the latest flagship or the Samsung galaxy or iPhone. This is exactly what comes to play when we consider image or brand before buying phones. Messi, Ronaldo, drake, our own wizkid and a whole lot of others use the iPhone.
  3. WHICH KIND OF OPERATING SYSTEM DO YOU WANT YOUR PHONE TO RUN? Is it Android, iOs, windows or blackberry?. without wasting much of our time, it is so obvious that we now have two major os mobile os out there; Android and iOS. others are okay but not at par with the two earlier mentioned

iPhone OS Windows mobile OS

Android dominates worldwide sales of smartphones, and for good reason. You’ll find many more choices than iOS when it comes to design, display size, specs, capabilities and price. Plus, Android is an open OS,

iOS 9 offers all sorts of enhancements. For example, Siri offers proactive suggestions to save you time, and the Notes app is a lot more robust. The Maps app finally offers transit directions too. The biggest reasons to opt for an iOS device include its ease of use, access to OS updates from day one (unlike Android) and ability to work seamlessly with Apple devices (such as the iPhone and the Mac) apple iPhone is in a class of its own. Apple’s App Store tends to get the hottest apps and games before Android, partly because developers have an easier time targeting a smaller set of devices that have similar specs.


A good processor inside a phone should translate to faster open times for apps, smoother gameplay and quicker photo editing, but you don’t have to pay attention to clock speed. It’s better to look at the performance results in online reviews and tech sites like, or via benchmarks such as Geekbench, which measures overall performance.

Among Qualcomm CPUs, the Snapdragon 830 processor is the class-leading chip, offering twice the overall performance and efficiency versus the Snapdragon 820. This results in more speed but also longer battery life. You’ll also get 40 percent faster graphics and speedier camera performance, along with better upload and download speeds over LTE.

4. RAM

Here’s an easy way to look at smartphones’ RAM, which is critical for multitasking(that is running several apps at once and switching in between them). Try to avoid handsets with just 1GB of system memory. On mid-tier devices, 2GB is good and standard. But you’ll find 4GB on the latest flagships, including the Galaxy S7 and the HTC 10. The exception is Apple, which uses 2GB of RAM in the iPhone 6s and the iPhone 6s Plus, though the lesser amount doesn’t seem to impact performance.

5. Battery Life

Many factors — including the screen size, processor and operating system — determine how long a smartphone lasts on a charge. However, shoppers looking for the longest endurance possible should check the specification of the batteries online fro reviews on sites such as gsmarena before buying the phone. Many sites offer battery test so you can predetermine this before purchase. It goes without saying that any phone that lasts longer than 8 hours of straight 3G  surfing to be acceptable, but greater than 9 hours is better.

6. Screen Size

Although bigger screens are in vogue, you’ll still find a wide variety of display sizes. And size is only part of the story. Small Screen (Less Than 4.5 Inches):The main reason to buy a small-screen smartphone is for its compact design,

Medium Screen (4.5 to 5.4 Inches): This has become the smartphone sweet spot, with such devices as the iPhone 6s (4.7 inches), the HTC 10 (5.2 inches), the Galaxy S7 (5.1 inches) and the LG G5 (5.3 inches) in this size range. Most phones in this category are fairly comfortable to use with one hand.

Large Screen/Phablet (5.5 Inches or More): Smartphones with displays larger than 5.5 inches, such as the 5.5-inch iPhone 6s Plus and the 5.7-inch Galaxy Note 5, are often called phablets because they are tablet-like in size. The screen size depends on the degree of visibility and reach that you demand from the phone.

7. Display Quality

The size of the screen is only one consideration. Pay a more close attention to a smartphone’s resolution, brightness, color quality and viewing angles.

The sharpest displays have quad-HD resolution, or 2,560 x 1,440 pixels, including the Galaxy S7 and the HTC 10. However, a full-HD panel with 1,920 x 1,080 pixels (1080p) — such as those on the iPhone 6s Plus — shows plenty of detail. The more quality your phone is, the more vivid and crisp  graphics. Make sure that the smartphone you’re shopping for has a panel that’s bright enough for you to be able to read it outdoors in direct sunlight.

8. Design

Defining a good or bad smartphone design is highly subjective, but if you care about build quality and aesthetics, look for a unibody design, which you’ll find on the iPhone 6, 6plus, 6s, 6s plus, 7 and 7 plus and the HTC 10. The Galaxy S7’s glass-and-metal design is particularly attractive, especially the S7 Edge with its dual curved display. People who prefer a smartphone with a removable battery should opt for a device such as the old Samsung galaxy phones prior to the release of galaxy S5 or new LG G5.

9. Internal Storage

Given that some games can easily take up more than 1GB — not to mention how many high-res photos and videos smartphone owners are capturing — we highly recommend opting for as much internal storage as possible that will satisfy your need. The minimum on most handsets, like the iPhone 6, is 16GB, but more phones (such as the Galaxy S7) are coming standard with 32GB. We recommend 32GB or more.

If extra memory matters to you, you can buy a phone with 128gb of internal memory or one with a microSD card slot. A microSD card can help expand your storage. It’s available on phones such as Samsungsung smartphones before galaxy s6,  the Galaxy S7, the LG G5 and the HTC 10.

10. Camera

Personally, I am crazy about a clear picture. This simply means am obsessed with any smartphone with a first-grade camera. We have now arrived at a point in smartphone evolution where the camera matters more than the processor, especially since most people use their phones as their primary shooters. More and more smartphones boast cameras with at least 12 megapixels, but don’t go by numbers alone. Instead, pay attention to image quality, aperture, pixel size, speed and features. The site I provided above”” has a blog that carries out an in-depth review of phones.

The Galaxy S7 and Galaxy S7 Edge currently offer the best cameras on any phone. Their dual-pixel cameras offer lightning-quick autofocus and take great pictures in low light, thanks to the wide f/1.7 aperture (lower numbers are better). By contrast, the 12-megapixel iSight cameras on the iPhone 6s and 6s Plus have an aperture of f/2.2. As far as camera features, look for optical image stabilization to reduce blur and improve low-light performance. The iPhone 6s Plus has it, but not the regular iPhone 6s. The Galaxy S7 and S7 Edge both have it. The HTC 10 is the first smartphone to offer optical image stabilization on the front camera, which results in better-looking selfies.


Wireless Charging

With myriad competing standards and a lack of direction from both smartphone makers and the carriers, wireless charging is more of a nice-to-have feature than a must-have at this stage. The idea is to place your device, such as the Galaxy s5, s6  S7, on a compatible wireless charging mat.  While it may be convenient, wireless charging likely won’t take off until the technology is built into everything from cars to furniture — or if Apple decides to adopt it.

Fingerprint Security

Popularised by the iPhone’s Touch ID sensor, fingerprint security on smartphones makes it easier to unlock your device. You can also use Touch ID to buy items in the App Store and real-world goods via Apple Pay. The sensor in the iPhone 6 was a bit sluggish, but the iPhone 6s’ fingerprint reader is faster.



If yu want to turn your phone into a game console, buy a tablet or a phanlet.

If physical keyboard matters to you buy a blackberry with one or buy a tablet and buy the keyboard for it separately.

  • Opt for an iPhone if you want a phone that’s easy to use and gets both the hottest apps first and the timeliest software updates.
  • Android is better if you want more hardware choice and more control over the user experience.
  • Get a phone with a 5-inch screen or smaller if one-hand use is important. Get a bigger screen if you like to watch a lot of video and play games.
  • The camera has become the most important smartphone feature. Pay attention to specs like pixel size (in microns, bigger is better) and aperture (lower numbers are better) and ignore the megapixels.
  • If you want the most speed for games and multitasking, buy an Android phone with the latest Snapdragon 830 processor and 4GB of RAM. The A9 chip in the iPhone 6s and the 6s Plus is also very speedy. A Snapdragon 615 chip is fine for mid-tier Android phones.
  • Don’t settle for a smartphone with less than a 3,000 mAh battery if endurance is really important.
  • 16GB phones are a rip-off unless you’re going to store most of your photos and files in the cloud. Get 32GB or more of storage if you plan to download lots of games or shoot 4K video.
