The Apple Watch Series 4 is the first predominant redesign of the Apple Watch, featuring larger displays with thinner bezels and rounded corners and a slightly rounder, thinner chassis with a redesigned ceramic back.
Internally there is a new S4 64-bit dual-core processor, capable of up to double the S3’s performance, upgraded 16 GB storage, and a new electrical heart sensor. The microphone was moved to the opposite side between the side button and the digital crown to improve call quality. Other changes include the digital crown incorporating haptic feedback with the Apple Haptic Engine and the new Apple-designed W3 wireless chip.
The ECG system has received clearance from the United States Food and Drug Administration, a first-ever for consumer device, and is supported by the American Heart Association. The Series 4 can detect falls and automatically contact emergency services unless the user cancels the outgoing call.

Design
| Type Design Type called form factor refers to a mobile phone's size, shape, and style as well as the layout and position of major components of phone. There are three major form factors seen in mobile phones => bar phones, folding phones and sliding phones. | Bar |
| Weight | 30 g (1.06 oz) |
| Protection |
Glass front, ceramic/sapphire crystal back, aluminum frame 50m water resistant ECG certified (region-dependent SW application; HW available on all models) |
| Colors | Silver, Gold, Space Gray |
Display
| Display Type Display Technology => A number of display technologies and types used in mobile phones => TFT (Thin Film Transistor), IPS (In-Place Switching), OLED (Organic Light Emitting Diode), AMOLED (Active-Matrix Organic Light-Emitting Diode), Super AMOLED (an even advanced version of AMOLED), Resistive Touchscreen (Resistive touchscreens contain two layer of conductive material with a very small gap between them which acts as a resistance), Capacitive Touchsceen (Capacitive touchscreen technology consists of a layer of glass coated with a transparent conductor) | LTPO OLED Retina display with Force Touch |
| Size | 1.57 inch |
| Resolution | 394 x 324 pixels |
| Pixel Density Pixel Density (PPI) is refers to the concentration of pixels on a particular display, measured in pixels per inch (ppi). Pixel density is calculated by dividing the diagonal pixel resolution of a display by its diagonal size, higher pixel density better display quality. | 326 PPI density |
| Display Protection Display Protection => Gorilla Glass is a special alkali-aluminosilicate glass shield with exceptional damage resistance that helps protect mobile displays from scratches, drops, and bumps of everyday use, It is always better to go for a smartphone with Gorilla Glass for that added protection and peace of mind. | Ion-X strengthened glass |
| Features |
3D Touch display 1000 nits brightness |
Network
| SIM SIM (Subscriber Identity Module) is a small card that contains mobile network subscriber's account information. This allows the phone using the card to attach to a mobile network. The SIM card is most commonly associated with GSM and UMTS mobile networks. Moving a SIM card from one phone to another allows a subscriber to switch mobile phones without having to contact their mobile network carrier. SIM cards can also be used by a phone to store limited amounts of data, such as phone numbers and text messages. | eSIM |
Media
| Loudspeaker | Yes |
| 3.5mm Audio jack | No |
Software
| Operating System OS => Every computer system run on a base software called Operating System (OS). Operating System controls all basic operations of the computer (such as smartphone, PDAs, tablet computers and other handheld devices). The Operating System allows the user to install and run third party applications (apps), apps are used to add new functionality to the device. | watchOS 5.0, upgradable to 8.6 |
| User Interface UI or user interface of a device is the look and feel of the on-screen menu system. How it works, its color scheme, how it responds to button presses, all of these things are part of the user interface. | watchOS |
Hardware
| Chipset Chipset is a group of integrated circuits designed to perform one or a more dedicated functions, often with real time computing constraints, Popular smartphones are equipped with more advanced embedded chipsets that can do many different tasks depending on their programming. | T8006 "Apple S4" |
| CPU CPU (Central Processing Unit) mostly known as processors, CPU processes instructions in order to carry out certain functions that make your device operate properly. Processors are often described as the brain of computers, smartphones and tablets, Smartphones and tablets rely on processors to carry out their every task, Processors are an incredibly important factor in selecting any type of computing device, including your smartphone. | Dual-core |
| GPU GPU (Graphics Processing Unit) is a single-chip processor designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display, This includes things such as lighting effects, object transformations, and 3D motion. | PowerVR |
| RAM (Memory) RAM (Random Access Memory) is a type of computer memory that can be accessed randomly, any byte of memory can be accessed without touching the preceding bytes that allows information to be stored and accessed quickly from random locations. RAM is the most common type of memory found in computer systems, smartphones, tablets and other electronic devices. | 1 GB |
| RAM Type | LPDDR2 |
| Internal Storage Internal Storage is a data storage space (flash memory) mostly used in smartphones, tablets and other electronic devices where operating system, apps, music, photos, videos, files and other user data Is stored. | 16GB |
| Card Slot Memory Card Slot is a special slot for inserting a memory card. Memory cards allow you to expand the phone's built-in memory, A memory card (sometimes called a flash memory card or a storage card) is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable or remote computing devices such as mobile phones, mp3 players, digital cameras. | No |
| Sensors Sensors are electronic components that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure and location, The output is generally a signal that is converted to use in computing systems, a location sensor, such as a GPS receiver is able to detect current location of your electronic device. |
