The display is arguably one of the most important components of any smartphone, and you can evaluate the display of any smartphone based on three factors.

  • screen resolution – This is the factor that mainly decides how many pixels will be packed on your screen, and it mainly determines the quality of the display. The standard resolution these days is 1080p or FHD, and you shouldn’t settle for less. If you want a premium smartphone then make sure that you have QHD resolution on your smartphone.
  • screen technology In the past, smartphones came with poor quality IPS screens, but technology has improved and today’s IPS screens are very sharp. However, if you want the best display quality, you should consider OLED technology as it comes with accurate colors and deeper blacks. In short, if you buy a mid-range smartphone, you can expect an IPS or OLED display. However, if you are buying a flagship smartphone, don’t settle for less than an OLED display.
  • Refresh rate Refresh rate is basically the metric that indicates how many times per second your screen will refresh. Most smartphones come with a 60Hz refresh rate, and this will work for most people. However, if you are a gamer, you should consider a 90Hz or 120Hz refresh rate monitor as it will enhance the gaming experience for you.



Nowadays, smartphones are equipped with great cameras and they can take great photos. When it comes to rating the cameras on any smartphone, you can rate any camera based on two factors.

  • sensor size – Sensor size is basically the size of the sensor, and it is given in megapixels, for example, 12MP, 50MP, etc. If you want to use your smartphone for casual photography, you should consider using a 12MP or better camera, like a 50MP.
  • Opening – No matter what size your sensor is, if it doesn’t get enough light, you won’t be able to get better photos, and that is determined by the aperture. Many Chinese companies usually offer large sensors in their smartphones, but they usually have an f / 2.4 aperture, which means that the sensor will not get enough light and you will get poor quality photos. So, when choosing your camera on a smartphone, make sure you get f/1.8, f/1.6, or better aperture for great shots.



The battery is another very important component that makes or breaks the entire experience. If you get a phone with an underperforming battery, you will not enjoy it and will spend a lot of time charging the device. Now, when it comes to battery rating, you can rate it based on two factors.

  • battery size Battery size is the factor that will determine how long the battery will last. The normal range these days is 4,000 mAh, and you shouldn’t settle for less. However, if you get a smartphone with a battery of 4,500mAh or more, you can get excellent battery life, and if you are a regular user, it can last you a whole day.
  • Battery charge time – If you do not want your phone to take hours to charge, it is important that you choose a fast charging phone. Fortunately, most smartphones these days feature fast charging and can charge the battery in 90-120 minutes, depending on the size and technology. Therefore, when choosing a smartphone, make sure that it has fast charging.

Specifications - How to choose the best smartphone

Finally, the specifications of the phone are also very important. When it comes to specifications, you can evaluate it on the basis of the following factors.

  • ram: The standard RAM these days is 6GB, and you shouldn’t settle for less. However, if you want to protect your phone in the future, make sure you have 8GB of RAM or more on your device.
  • Storage: The standard storage these days is 64GB, but that might not be enough for power users. So, if you choose 256GB storage, you won’t have to worry about space for long.
  • Healer: The processor is arguably the most important factor to consider when buying a smartphone. If you bought the latest smartphone, make sure it has the latest processor. The quick way to find out is a quick Google search. If the processor is from last year, you shouldn’t get the phone unless you get it at a bargain price.
