Apple has always put customer satisfaction and quality first in the design of their products, and the creation of the iPhone is no exception. The iPhone truly represents a new era of gadgets for communication and entertainment. Here are the hardware components of the iPhone that has contributed to its functionality.
The touch screen is made of a 3.5 inch LCD (liquid crystal display) with a resolution of 320 by 480 pixels at 160 pixels per inch. The HVGA touch screen has a scratch-resistant and optical-quality glass, which is designed to be used with a single finger or multiple fingers. (0Multi-touch sensing requires multiple fingers, of course.) The screen can be used without a stylus. Actually, it does not allow the use of a stylus, even if the user did have one. However, the user has to be bare-skinned at the finger. Gloves should be removed, unless they are electrically conductive gloves.
The interface also has some other visual effects, like the system menus that can slide vertically, sub-selections that can slide horizontally, and widgets and menus that rotate to enable the user to configure settings on their back side.
Audio and Video
As the user plays music, album art is displayed on the screen, along with the play controls below. The headphones resemble those of the latest iPod versions, with the addition of a microphone. Answering and ending calls can be done through When music is played on the iPhone, album art is shown on most of the screen, with play controls beneath. The iPhone’s headphones are similar to those of current iPods, but also incorporate a microphone. Calls can be answered and ended through squeezing the bud and toggling the microphone. The headphones can be connected on the top left corner using a 3.5-millimeter TRS connector. Wireless earpieces, which are sold separately, can also be used for the Bluetooth functions.
It also has a loudspeaker that can be used for media playback and hands-free operations. However, it does not allow voice recording.
The iPhone has an integrated battery, which is rechargeable. However, like iPods, the battery cannot be replaced. If the battery dies out prematurely, the phone may be brought to Apple to be replaced at no cost, if it is still under warranty. The period for the warranty is one year from the date of purchase and may be extended with Applecare for up to two years. If the phone is no longer covered with warranty, the battery may still be replaced by Apple, which would cost US$79.
The battery has been specified to have the capacity of lasting through six hours of Internet browsing, seven hours of playing videos or up to eight hours in talk time. It allows 24 hours of music playing and up to 250 hours in standby time. Apple’s website states that the life of the battery “is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles.” This is the same case in iPod batteries. Once the battery achieves at least 80% power, it would be able to provide more or less 4.8 hours of browsing the Internet, 5.6 hours of playing videos, 19.2 hours of playing music or 6.4 hours of talking on the phone, but this would all still depend on the configurations.
iPhone Sim Card
The SIM card can be inserted in a slot located on the upper portion of the device. There is no slot for memory card.
