As part on this tutorials, A good technician must also learn how to identify spare parts and how each particular parts works on cellphone handsets. Familiarizing each
Now various brands and models of every mobile phone products although have the same parts but differs on each sizes and technical specs. Others also are compatible with each other..
The Following are the most common types of spare parts you can find inside mobile phones handsets.
* Battery

BATTERY-
A battery is used to provide power supply to the PCB circuits and components. There Are various types of Batteries in each particular mobile phone products, and varies to each sizes and specifications. Manufacturers coded each particular packaged according to sizes and where specified product to use. The standard battery Voltage Range is 3.7V and is made of rechargeable Lithium Ion.
Battery Connectors
This the interface where the battery connects and supply the voltage to the cellphones main circuitry or PC Board. Old models used 4 pin which lead to four battery output sources such as +(positive) - (negative) BSI (battery status indicator) and Btemp (Battery Temperature)
The latest designs consists of only three pins, The + (positive) - (negative) and BSI (battery status indicator) the Btemp is diminished and still in cellphone circuitry included.
Antenna's
Antennas are used to intercepts and boost network signals, without it the phone will hardly connects to service providers and results network signal lost.
Antennas also consists of many types and sizes and varieties. It varies according to how each manufacturers designs. It is made of thin brass or stainless metal mounted on a plastic packaging.
LCD
Liquid Crystal Display(LCD) is the component that visualize the operation of a mobile phone handset. It is made of glass with tiny crystal fixel that imitate the light source that has programmed to display certain information such as text and images.
LCD also comes from wide range of specifications older LCD are called monocrome which only display one certain color. The later designs where multicolored and displays rich text and images. The higher the fixel amount on a certain LCD the higher the picture resolution of images can displays.
Camera Module
Camera Modules is the component used to capture and store images, also comes in different specifications and packaging. Examples of these modules are shown below.
Plug-in Connectors
Plug in connectors are interfaces used in charging or by charger plugging, USB and data cables. Various mobile products also have different plug-in connectors designs.
Flex Cable Wires
These are wires that is made into a flat thin wires used as an interface to connect from one circuit or components to another. It is called "Flex" means Flexible others also called it a "ribbon wire"
Joystick and Trackball
this a component parts which is used to navigate certain features on a mobile phones. It is commonly navigate "UP","DOWN","LEFT","RIGHT","MENU","ENTER" keys.
Touch Screen Panels
Touch screen panels are made of flat thin glass which is designed with high capacitive or capacitance value. It navigates everywhere on LCD screen by just using a finger to or a stylus pen to switch trough certain feature on a mobile phone handsets.
Microphone
A microphone also known as "mouthpiece"is the component used to intercepts and imitates human voice and sounds to sends to particular receiver or caller. Cellphone microphone are small and have different forms of packaging.
Speaker
Speakers are the components that are used to hear someone talking when a call is made,without it you can not hear the other persons voice calling at you. It is called an "earpiece by most common Technicians.
Buzzers and Ringers
These are also speakers that can generate high audible sound louder than Earpiece speakers. It amplifies the ringtones or voice or music more audibly.
Keypads Membrane
This are made of tiny round metals that acts as a switch in a row of letters and numbers characters on keypads mattress.
SIM Card Connectors
This is an Interface that acts as a holder and connects the Sim card to the PC board circuits.
ON and OFF Switch
It is made of tiny metal that conducts connectivity when press. It is being used as a power on and off, Volume control switch and camera shutter switch on various mobile phones.
Vibrator
it is made of a tiny motor that conduct vibration when in active mode. It has been attach an unbalance tiny metal on its tip, that is why it creates vibration when the motor rotates.
Other Parts
More Parts like LCD Frames, ON and OFF rubber buttons, Metal frames, Screws, Back housing, Face plates are also plays vital role on mobile phones packaging.
Some Parts may I have not included here, for some are just so rare in some mobile phone products.
Now various brands and models of every mobile phone products although have the same parts but differs on each sizes and technical specs. Others also are compatible with each other..
