What are the main reasons why phones break when dropped?
The main reasons why phones break when dropped are related to the physical properties of the materials used in their construction and the forces that act upon them during a fall. When a phone is dropped, it is subjected to a combination of stresses, including impact, compression, and tension. These stresses can cause the phone’s internal components, such as the screen, battery, and circuit board, to become damaged or dislodged. Additionally, the phone’s exterior casing and screen can crack or shatter due to the force of the impact, allowing dust, moisture, and other environmental factors to enter the phone and cause further damage.
The likelihood and severity of damage to a phone when it is dropped depend on various factors, including the height of the drop, the surface onto which the phone falls, and the phone’s design and construction. For example, a phone that is dropped onto a hard surface, such as concrete or tile, is more likely to suffer damage than one that is dropped onto a soft surface, such as carpet or grass. Similarly, a phone with a sturdy casing and a shock-absorbing material, such as silicone or rubber, may be more resistant to damage than one with a thinner or more brittle casing. By understanding the physical properties of phones and the forces that act upon them during a fall, manufacturers can design phones that are more durable and resistant to damage.
How does the screen material affect the likelihood of a phone breaking when dropped?
The screen material used in a phone plays a significant role in determining its susceptibility to damage when dropped. Most modern smartphones use either glass or plastic screens, each with its own strengths and weaknesses. Glass screens, such as those made from Gorilla Glass or tempered glass, are more resistant to scratches and cracks than plastic screens, but they can still shatter or crack when subjected to sufficient force. Plastic screens, on the other hand, are more flexible and less prone to cracking, but they can be more easily scratched or damaged by minor impacts.
The type of glass used in a phone’s screen can also affect its durability. For example, some phones use a type of glass that is designed to be more resistant to drops and impacts, such as Gorilla Glass 6, which is designed to survive drops of up to 1.6 meters. Other phones may use a type of glass that is more prone to shattering, such as soda-lime glass, which can be more easily damaged by minor impacts.
