Have bought your new smartphone and want to know what you can actually do with your phone? Or your tech-savvy friend telling you about his shinny phone’s amazing features and you looking at him more amazingly? Here this post is for you, let’s make some sense about the specs of your phone.
Day by day phones is going to be more and more advanced. But the main components are the same. So we at first divide them and then explain them one by one. Generally, the main components of a smartphone are the screen, battery, processor, OS version, graphical unit, camera, sensors etc. We now explain the components, features and related terms.
So let’s start now:
At first the BIGGER Screen:
Sizes of screens and features like display resolution, ruggedness are increasing and improving from time to time.
It needn’t any explanation, you can see how large your screen is, the larger the screen the easier the uses and you must have a more large pocket to carry your jumbo phone.
Resistive And Capacitive Touch Screen:
There are two types of touchscreens used in smartphones. Resistive touch screens are the older model than capacitive. In resistive touchscreen two separate plates are separated by an air gap or other resistive materials and when you touch the screen the resistance between the touched area changed and the current flows thereby the screen works. In capacitive touch screen, the glass (insulator) is coated with some transparent conductor. As our body is a conductor also when we touch the screen the electrostatic field below this area changed and the screen works.
The difference between these two is the capacitive touchscreen is more responsive than resistive ones but it need direct contact with your skin, if you touch your phone wearing a glove then the resistive will work fine but the capacitive will not work as the materials of the glove is an insulator.
TFT and IPS LCD Screen (Display):
TFT display and IPS display are variants of LCD screens, TFT stands for Thin Film Transistor Display and IPS stands for In-Plane Switching display. IPS is more advanced technology and supports larger viewing angle than TFT display. Modern phones and monitors use IPS or more advanced IPS display technology.
Screen Resolution SD, HD and FHD, AMOLED, Full Optic AMOLED and Super AMOLED and PPI or DPI:
Screen Resolution is often written in terms of pixels, (pixels are the tiny dots constructing your screen; look at your screen neatly you can see those tiny dots) like 1280×720; 1900×1080 or 2280 x 1080. Resolution also written as HD or FHD; HD stands for High Definition and FHD stands for Full High Definition. AMOLED (active-matrix organic light-emitting diode) Display is an advanced type of LED display with a much thinner construction. Super AMOLED Screens are same as AMOLED but with higher performance and refresh rate and thereby higher operating speed also, but based on the same technology.
PPI stands for pixels per inch and DPI stands for density per inch, its the measure of pixel density. It denotes how many tiny dots (pixels) are populating the unit area of your screen.
Corning Gorilla and Dragontrail Glass types :
Its everything on the screen so the screen is the most important part, and everyone wants a relly really tough and unbreakable screen. But there is NONE unbreakable (except in the ads) but some special types of glasses are really hard enough that it not get lost if your phone drops sometimes from your hand. Corning Gorilla Glass and Dragontrail Glass both are alkali-aluminosilicate glasses and both are tough and hard enough to break, though nothing is unbreakable, both of these two can protect your phone up to some extent. Grilla is more famous than Dragontrail, many device manufacturers use Gorilla glass not only for mobile devices but for other devices like TVs, Cars and Monitors too.
No one (probably) happy with their Phone’s battery performance. Battery powers are measured in mAh units. The full form is mili Ampere hour. Power of Large batteries like Lead- Acid battery for household purposes are measured in Ah unit I.e., Ampere hour. Phone batteries are small units so it measured in mili unit.
You may have seen Li-ion or Li-Po battery written on your phone’s battery. Here Li means Lithium – a metal and Po stands for polymer. Li-ion batteries are older versions and use liquid chemical mixture as electrolytes, so there was a risk of sudden exposure or leakage of inner chemicals which may cause accident, later Li-Po batteries are invented which use a gel type (or even solid) chemical mixture as electrolytes which is less risky. Though Li-ion batteries are more efficient than Li-Po batteries.
You may have seen MP written in camera specification. MP stands for megapixel. Pixels are constructing dots of photos and videos, and so this is the number of pixels actually constructing the image. So higher the camera capability the more pixels are used to construct the image and so the quality of the picture will better too.
PDAF stands for phase detection auto-focus i.e., the camera intelligently focusses on the object image you going to capture. It will focus faster and help you to capture the best image possible.
OIS stands for Optical Image Stabilization, the camera lenses automatically make the image more stable when capturing and hence it reduces the blurring effects in the image, if you have shaky hands this feature can help you capture better photos.
FPS meaning Frames Per Second, a video is constructed with some moving or changing still images (frames); human eye cannot detect differences between the images if the time gap is less than .1 second. Here fps is the measure of how many frames are passing per second when the camera used for capturing a video.
Aperture value of a camera actually means the measure of the opening through which light travels inside the camera through the camera lens. It measured by f-stops unit, such as f-2.0 or f-8.0 etc. The lower the f-number the larger the aperture, so the camera being more sensitive to light.
The full form of RAM is Random Access Memory. The role of RAM is to store the works temporarily before transferring it to ROM or hard drive. The more the RAM the more efficient the device. For smoother gaming devices with much RAM are more efficient because gaming needs more instantaneous storage and if your phone have lesser RAM then lags are frequent so gaming experience will not better.
ROM refers to Read Only Memory, actually ROM does not mean the storage memory it is the storage space for system software and firmwares, but sometimes ROM also referred to as the total memory space provided with the device for storage purpose.
The memory space provided by the device manufacturers for storage purposes (like your videos, songs, documents etc.).
Like a PC, phones have also a central processing unit i.e., CPU commonly called as processor (hope you have heard about intel – the king manufacturer of PC CPU). There are also some big players im mobile industry too, namely Qualcomm, TSMC (Taiwan Semiconductor Manufacturing Company) and MediaTek. Modern phones use multi-core processors (cores are independent processing units inside the whole processor) like dual core, quad core or octa core etc. Almost all important smartphone features are dependent on processor capability.
Apart from the CPU phones also need a GPU (Graphical Processing Unit) to render the display and graphics visually to the user, GPUs are embedded with the CPU within a single SoC (System on a Chip), different CPU makers use different GPUs, like Qualcomm uses Adreno GPU, MediaTek uses Mali GPU (based on ARM) etc. Your visual experience depends on GPU performance.
Modern Smartphones supports many connectivity options, like GSM, WCDMA, VOLTE etc.
GSM (Global System for Mobile communications) is the standard mobile communication system for transmitting data and voice, this technology is standard and used by all SIM card supported mobiles. Normal frequency bands used for GSM service are 850/900/1800/1900 MHz, some countries or areas have exceptions also (380 – 2100 MHz).
3G, W-CDMA, UMTS, HSPA, FDD, UTRA-FDD:
All the names are 3G connectivity options, with some more or less advancement and features.
4G and VOLTE:
4G is more advanced than 3G, and the VOLTE (stands for Voice over Long-Term Evolution) is a technology which support HD voice call and high speed data service.
Ambient light sensor:
Its a technology developed with light sensing diodes which adjusts screen brightness according to the external brightness e.g., sunlight, so it reduces eye-strain when using the phone and helps serve brilliant display quality, it also saves battery dimming the brightness at night or low light condition.
Proximity sensors sense nearby object to the device without touching the device, it used in air gesture feature (Changing gallery photo with out touching the screen) or turning the light off automatically when the device is held near ear during an ongoing phone call.
Hall effect sensors or Hall sensors are based on Hall effect a physical phenomena which used to detect either flip cover is closed or not, if the cover is detected as closed it automatically turn the lights off.
IR Sensors detects IR lights, Color temperature sensor is used in a camera to detect color temperature which helps capture the correct photo in different external light conditions (Something like the white balance feature).
You know its an incomplete list, everyday smartphones are going to be more advanced with more and more features, this is a common list of features which I think help you to interestingly discover your smartphone features and enjoy it.
