By the end of this guide, you'll know exactly which features are most important for you and how to select a phone that offers the best value for your money.

Buying guide for phones: Key factors you should look for


Factors to look for while buying a smartphone

1. Display size:

The size of the display is one of the most crucial aspects to take into account when selecting a smartphone. This establishes how convenient it is to use with one hand or how small it can fit in your pocket. A smartphone's screen size is expressed in inches and measured diagonally.

Most smartphones have screens that are six inches or larger. A phone with a display size between 4 and 6 inches might be something to look into if you don't like the idea of a large smartphone or want to be able to use it with one hand. However, a display size larger than 6 inches is advised for heavy video editing, intense gaming, split-screen work, e-reading, and movie

2. Display type

Display type is another important factor that affects the viewing experience. Smartphones are now available with LCD, Retina, OLED, and AMOLED panels, each of which has optimal use cases, viewing angles, and color reproduction capabilities of its own. Here are all the display type explained.

LCD display:

Liquid crystal displays, or LCDs for short, are a common option for smartphones and other devices due to their affordability and widespread use. The term LCD refers to a collection of liquid crystals that are backlit by a backlight.

Relying on a TFT (Thin Film Transistor) layer with an active matrix, modern LCDs are less expensive and complex than their low-resolution, passive counterparts, like the ones found in many calculators, vintage watches, and even the original Game Boy. Because tiny transistors regulate the current received on each row and column of pixels in a TFT, each pixel can be turned on or off without requiring a dedicated connection.

OLED display:

Organic Light Emitting Diode, use OLED. Thin sheets of electroluminescent material make up an OLED display; as the name suggests, these materials emit light when current is applied to them. OLED displays are "always off," unless the individual pixels are powered, in contrast to backlit LCD panels.

This indicates that when black or darker colors are shown on the screen, OLED displays have much purer blacks and use less energy. On the other hand, OLED screens with lighter color themes consume a lot more power than an LCD screen with the same theme. The cost of producing OLED screens is higher than that of LCD screens.

In comparison to LCD screens, OLED displays have higher contrast ratios since their black pixels are "off." Although OLED displays can also have very quick refresh rates, they are not as visible in bright light as backlit LCDs. Other things to think about are screen burn-in and diode degradation (since they are organic).

AMOLED display:

Unlike PMOLEDs (passive matrix OLEDs), which drive the display on a row and line level, AMOLEDs (Active Matrix OLEDs) use a TFT layer to control individual pixels. The outcome is comparable to LCDs and enables larger and denser screens. Generally speaking, every OLED screen available today is an adaptation of AMOLED technology.

Apple's ProMotion, Liquid Retina, and Liquid Retina XDR:

The term "Retina" was first used in the past to refer to LCD screens that have "Retina" resolutions, meaning that at standard viewing distances, the human eye cannot distinguish individual pixels. According to paper, every iPhone model since the iPhone 4.

Apple uses the term "Liquid" for the LCD panel and "XDR" for the HDR capabilities in its Mini LED technology. Another marketing term used by Apple to characterize screens with high refresh rates and dynamic adjustment is ProMotion. Comparable to the Dynamic & Fluid prefixes discussed earlier, but applicable to LCD screens in the case of Apple as well.

Refresh rate

The number of times your screen is refreshed every second is known as the refresh rate. The smoother your video viewing experience is, the higher the refresh rate, which is measured in Hz. Calling, light web browsing, and light social media use are best served by 60 Hz, whereas heavy web browsing, email, social media usage, light gaming, and editing are best served by 90 Hz. On the other hand, intense gaming, watching movies, and video editing work best at 120Hz and higher.

RAM and storage

A 4GB smartphone would be plenty if you're searching for an entry-level model. It would be best to get a phone with 6GB of RAM if you're looking for something between Rs 10,000 and Rs 15,000 because it can hold more apps at once. It's best to spend your money on a smartphone with 8GB of RAM if you want to buy a mid-range or high-end phone that costs between Rs 15,000 and Rs 35,000 in order to enjoy more seamless multitasking. It would be wise to get a phone with at least 12GB of RAM if you're planning to buy a flagship device.

However, in case of iPhones, things are different. Last year’s iPhone 15 Pro Max had only 8GB RAM, still it’s one of the most efficient phones available in the market. iOS is known for its efficient memory management and optimisation, which allows it to deliver smooth performance even with relatively lower amounts of RAM compared to some Android counterparts. Even iOS apps are designed in such a way that they work efficiently even with less amount of RAM.

In terms of Storage you can get a smartphone with 64GB and above depending on your need.

Processor

A processor is comparable to a smartphone's brain. You can say that almost everything you do on your smartphone is dependent upon it. Nevertheless, purchasing an expensive flagship smartphone is necessary to get a high-end processor. The tasks and apps you use on your phone will determine how much processing power you require, though. Selecting a smartphone with a processor that provides the ideal amount of power while remaining comfortably within your budget is crucial. Performance of a processor is primarily determined by two factors: the number of cores and clock speeds available. A variety of multi-core processors are available in the latest generations of smartphones. Dual-core (two), quad-core (four), and octa-core (eight) processors are the most prevalent. Here are mostly used processors:

Qualcomm:
Leading the processor industry, Qualcomm is well-known for its Snapdragon chipsets, which include models 4, 6, 7, and 8. These drive a number of high-end flagship devices from Xiaomi, OnePlus, and Samsung.

Mediatek:
Mediatek is another manufacturer known for powering flagship and mid-range smartphones. The popular Helio and Dimensity chipset families from Mediatek power 4G and 5G smartphones, respectively.

Apple:
Apple design its own chipsets exclusively for its own line of products only. All iPhone chipsets, starting with the A14 Bionic, are capable of supporting 5G technology.

Exynos:
Similar to Apple, Samsung also make Exynos mobile processors exclusively for its smartphones. Many Samsung smartphones, including the entry-level Galaxy J series models and the flagship Galaxy S series models, are powered by the same processor.

Camera
One of the first things that most of us look for in a smartphone is a camera. A good smartphone camera is now a need rather than a luxury in an era where social media and remote work have become integral parts of our lives.

Every manufacturer sells smartphones with various camera configurations, each with special features. Three primary types of smartphone lenses exist: telephoto or zoom, ultra-wide angle, and primary sensors.

Primary sensors:

When you open the camera app on a smartphone, the default camera is the primary lens. It is perfect for taking close-up pictures of everyday subjects. Additionally, the primary lens—which a phone may or may not have—always has the highest image resolution of all the sensors.

Ultra-wide-angle sensor:
Smartphones now comes with a wider field of vision between 117 and 123 degrees thanks to an ultra-wide-angle sensor. These lenses come in handy for taking pictures of landscapes at sunsets or perhaps of a sizable gathering of people, like at a wedding.

Telephoto sensors:
Telephoto sensors let you take pictures of distant objects. Essentially, it lets you enlarge an image without sacrificing quality when zooming in on a distant subject. These sensors come in handy for photographing things like wildlife.

What is Megapixel?
Digital image resolution is measured in pixels and megapixels, which are counted per inch. One million pixels, or discrete bits of data that go into creating an image, make up one megapixel.

When talking about the quality of their photos, the majority of smartphone brands usually mention the number of megapixels on the device. Though having more megapixels does contribute to sharper images, it is important to remember that this is not the only factor.

Other additional camera features:

Artificial Intelligence takes away all the hassle of photography; Optical Image Stabilization mechanism reduces blur in your images; High Dynamic Range (HDR) helps capture images with a better dynamic range; and Portrait Mode, which uses the Bokeh Effect to blur the background of your images and enhances your selfies and portraits.

Battery and Charging support

The battery life of a phone is very important, especially for people who are constantly on the go. Larger values, expressed in milliampere-hours (mAh), typically correspond to longer battery life. When used moderately, phones with batteries ranging from 4,000 to 5,000 mAh can usually last an entire day. Fast charging, on the other hand, is a modern necessity. With the fast charging technology found in many smartphones, you can charge your phone to 50% capacity in just 30 minutes. Convenience is increased by the fact that many high-end models offer wireless charging.

Conclusion
Buying a smartphone requires careful consideration of both your needs and your budget. It will be easier for you to choose if you focus on battery life, camera quality, and overall performance. Understanding these key factors will help you make an informed decision. So, the next time you're on the hunt for a new smartphone, our guide will help you find the perfect phone that fits in your lifestyle and budget.
