  10. Connectivity ports (e.g. USB, headphone jack)

Before buy check these parts of a smartphone.

1. Display protection: There are 3 main types of display protection on smartphones:

  • Tempered Glass - It is a sheet of glass that is specially treated to increase its strength and durability.
  • Plastic Films - Thin, adhesive plastic film that covers the display.
  • Liquid Screen Protectors - Liquid solution applied to the display to form a protective layer.

All these types of protection work by adding a layer of material over the phone's display to protect it from scratches, cracks, and other damage. Tempered glass is the most common and provides the most protection but is also the most expensive. Plastic films are less expensive but also provide less protection. Liquid screen protectors are easy to apply and can provide good protection but can also be prone to peeling or bubbling over time.

2. Processor of Smartphone: A smartphone processor, also known as a central processing unit (CPU), is the main computing component of a smartphone. It is responsible for executing instructions and managing the phone's resources (such as the display, memory, and battery) to perform tasks such as running apps, playing games, and handling basic phone functions. The processor's speed, efficiency, and capabilities play a major role in determining the overall performance of a smartphone.
There are 2 main types of processors in smartphones:

  • ARM processors (e.g. Qualcomm Snapdragon, Mediatek)
  • Apple's A-series processors (e.g. A12 Bionic, A13 Bionic)

As for the best processor of the present time, it is subjective and depends on the intended use and specific needs of the user. However, in terms of high-end performance, the Apple A15 Bionic and Qualcomm Snapdragon 888 are considered to be among the best processors currently available.

3. Battery of Smartphone: The best mAh (milliampere-hour) rating for a smartphone battery depends on various factors such as the phone's size, display, processor, and usage habits of the user. A higher mAh rating generally indicates a larger and more powerful battery, which can provide longer battery life.
There are several methods to check if a smartphone battery is good or bad:

  • Battery Health Status: Some smartphones have built-in battery health status indicators that provide information on battery capacity and overall health.
  • Charging and Discharging Cycles: The number of charging and discharging cycles a battery has undergone can affect its capacity and overall health. A battery with a large number of cycles may have a reduced capacity.
  • Battery Drain Test: You can perform a battery drain test by using the phone for normal activities and measuring the battery percentage over time. A healthy battery should be able to hold a charge for a reasonable amount of time.
  • Third-Party Apps: There are several third-party apps available that can test battery performance and provide information on battery health and capacity.

It's worth noting that battery performance can degrade over time due to usage and age, even if the battery has not reached the end of its lifespan. In such cases, replacing the battery may be necessary to improve performance.

4. Camera of Smartphone: A smartphone camera is a digital camera integrated into a smartphone. It allows users to capture photos and videos, and has become an essential feature for most smartphone users.
In a user's life, a smartphone camera can be used for a variety of purposes, including:

  • Recording videos for vlogs or video blogs
  • Capturing landscape and nature shots
  • Taking product photos for personal or commercial use
  • Facilitating video calls and conferences
  • Scanning QR codes and documents

Users can take advantage of various camera features, such as auto-focus, image stabilizationization, and filters, to improve their photos and videos. The smartphone camera has also become an important tool for creativity and self-expression.
There are several types of smartphone cameras, including:

  • Single Lens Camera
  • Dual Lens Camera
  • Triple Lens Camera
  • Quad Lens Camera

Single lens cameras are the most basic type and found in entry-level smartphones. Dual lens cameras offer improved zoom and depth-sensing capabilities. Triple lens cameras offer even more versatility with additional lenses for wide-angle and telephoto capabilities. Quad lens cameras and above offer even more options for capturing different types of photos and videos.

5. Sensors Of Smartphone: Sensors in a smartphone are used to detect and respond to physical changes and inputs from the environment. Some common types of sensors found in smartphones include:

  • Accelerometer: measures the phone's acceleration and orientation, allowing it to detect when the phone is being moved or rotated.
  • Gyroscope: measures rotational motion and helps with tracking and stabilizationizing the phone's position.
  • Proximity sensor: detects when the user is holding the phone close to their face, and turns off the screen to prevent accidental touches.
  • Ambient Light Sensor: measures the ambient light level, adjusting the phone's display brightness accordingly.
  • Fingerprint sensor: reads a user's fingerprint for biometric authentication.
  • Compass: determines the phone's orientation relative to magnetic north.

  3. Compare the audio output of the speaker with that of a known good speaker or headphones to get a reference for comparison.
  4. Place the phone in different positions to check for any changes in the sound quality.

Note: If you find any issues with the speaker quality, you may consider repairing or replacing the speaker.

8. Motherboard of Smartphone: The motherboard in a smartphone is the main printed circuit board that houses the central processing unit (CPU), memory (RAM), storage (ROM), and other components that make up the smartphone's electronics and control its functions. It acts as a bridge between the various hardware components, enabling them to communicate and transfer data with each other. The motherboard is responsible for running the smartphone's operating system, executing applications, and managing other vital functions. It is a crucial component in the smartphone and is responsible for its overall performance and stability.
