A modern user guide for buying a new smartphone


Smartphones are a marvelous creation that has made life easy and flexible. Although communication is the most vital function of these devices, they have also become a top choice for recreational purposes. Before buying a new smartphone, we often research and compare the best features available within our budget. As a modern smartphone user, here are some key features to keep in mind when shopping for your next mobile companion.


The platform can be a major decision point when choosing a new smartphone. Both iOS and Android have their pros and cons, but if you’re used to a specific platform, it’s best to stick with that one. However, if you are open to a change, switching platforms is always an option.

For all the latest news, follow the Daily Star’s Google News channel.

Android is the most used platform which comes in different ranges. Designed by Google and used by most manufacturers, Android smartphones have access to the Google Play Store and a wide range of applications. Expert users will often say that Android devices open up the reach of a smartphone because you can test out various customization features, combinations of services, and built-in apps that Apple doesn’t always give freedom for.

iOS is the platform used by iPhone. These devices are fun to use, but they come in a high price range, due to their unique and secure multimedia features. Those who prefer iPhones to Android do so primarily for management and access security. iPhones’ browser prevents smart tracking and third-party access to personal information. In addition, password protection, two-factor authentication, restriction of location information, control of website access and cookies, security of email addresses, etc., offer to its users an exclusive and safe experience.

Screen and design

Check the sensors, their positions and their handling before making your purchase. The screens are available in LCD OLED and AMOLED. If you want better contrast, OLED is the choice for you. LCD screen has lighter blacks than OLED. AMOLED screens are expensive but more efficient. The iPhone and Galaxy range of Samsung phones use an AMOLED display.

Since the screen is the most visible part of a smartphone, find one with optimal resolution and size. The size range for high-end devices is 5.5 inches to 6.5 inches and larger. The screen should be Full HD, as anything over 1080 pixels is good quality and crisp. The aspect ratio of a standard smartphone screen is 18:9.


The performance and efficiency of smartphones depends on these two parts. To get the best performance from Android phones, you will need a new processor with at least 4 GB of RAM.

But this is not the same case in the case of iPhones. iPhones do not require as much RAM because their memory management is handled differently. For iPhones, the best processor is the A-series chipset. For Androids, it’s the Qualcomm Snapdragon 865 Plus.

When it comes to memory, modern smartphones come with built-in storage. Starting from 16 GB, the amount can also reach up to 512 GB. For efficient use, at least 64 GB is recommended, as it speeds up the functionality of the device. You can also expand your device’s memory using an SD card.


The quality of a smartphone camera does not only depend on the megapixel of the device. It includes other factors such as camera sensor and lens aperture. If you want a phone with a good camera, test it out yourself and check reviews for better information. While some brands offer better resolution, exposure, color, and focus, others offer fancy choices and creative click options. Choose according to your preference.

Most smartphones come with a triple or quad camera setup with a resolution of around 48 megapixels to 50 megapixels. For experimental photography, you can look for special features like optical image stabilization and ultra-low light sensors. For the front camera, a 13-megapixel to 20-megapixel single camera setup is most common. Look for the best selfie camera if you are a fan of selfies. For those who prefer mobile videography, there are features like a 4k video shooting option and 60-90Hz refresh rate. Go for smartphones that support these features for an enhanced videography experience.

Two popular high-end smartphones in the market in terms of camera features are Google Pixel 6 Pro and iPhone 13 Pro Max. Both are extremely good at taking photos with some slight differences between them. Google Pixel 6 Pro has a 50MP main camera, while the iPhone 13 Pro Max has a 12MP camera. Both brands support 4k videos with a refresh rate of around 60Hz. Apple phones tend to deliver very vibrant photos thanks to their excellent sensors. Pixel delivers much sharper, more color-accurate photos.


The most common problem in smartphones is the battery. So, choosing a smartphone with the right balance between performance and battery life is of great importance. 5000mah batteries are standard for most smartphones. Usually these batteries offer up to 13 hours of screen time. The storage capacity or mAh rating will give you an idea of ​​the battery life. However, many other factors determine the battery life of a smartphone.

Resolution, refresh rate, screen size, and processor type should be considered when determining battery life. Be sure to check the screen display time before buying a smartphone. As batteries increase in capacity, unit loads also increase. Most smartphones these days support 18W to 65W charging bricks, allowing for faster charging in shorter periods of time – even being able to charge a 5000mAh battery in 15-30 minutes.

For device durability, buy water-resistant devices. Flagships have higher ratings and are fully waterproof, but many budget or budget devices can handle a few minor spills.

To future-proof your purchase, consider the material your phone is made of in addition to the design and other hardware. Review the maintenance policy of different brands before buying your phone.

Google, Xiaomi, and OnePlus offer a service policy of about three years at most. Samsung’s lead time is two years, and a few more years on select devices only. Apple and Sony are two brands with no warranty policy. But Apple has its fame for providing better and regular new functions and updates.
