Price comparison

Design

1.weight

126g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
2.thickness

9mm

We consider a thinner chassis better because it makes the product more compact and portable. Thinness is a feature highlighted by many manufacturers of mobile devices, but it is essential for a wide range of products.
3.height

133mm

The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
4.width

65.4mm

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
5.volume

78.28cm³

Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.

Display

1.pixel density

218ppi

Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
2.resolution

480 x 854px

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
3.screen size

4.5"

The bigger the screen size is, the better the user experience.
4.LCD display with 3 subpixels per pixels
Coolpad Roar
The device has an LCD display with 3 subpixels per pixel, resulting in sharp and crisp images. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.
5.has an IPS screen
Coolpad Roar
IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of conventional twisted nematic TFT displays: limited viewing angles and low-quality color reproduction. PLS (Plane-to-Line Switching) is a type of IPS screen developed by Samsung, with increased brightness and lower production costs.
6.has a touch screen
Coolpad Roar
You can operate the device easily, by pressing the screen with your fingers.

Performance

1.CPU speed

4 x 1.3GHz (MediaTek MT6580)

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
2.RAM

1GB

Random-access memory (RAM) is a form of volatile memory used to store working data and machine code currently in use. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing.
3.has an external memory slot
Coolpad Roar
The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.
4.internal storage

8GB

The internal storage, also called read-only memory (ROM), refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device.
5.semiconductor size
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
6.GPU clock speed
The graphics processing unit (GPU) has a higher clock speed.

Cameras

1.megapixels (main camera)

5MP

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
2.megapixels (front camera)

2MP

The number of megapixels determines the resolution of the images captured with the front camera. A higher megapixel count means that the front camera is capable of capturing more details, an essential factor for taking high-resolution selfies.
3.has a flash
Coolpad Roar
A flash is good for low-light environments, and can sometimes be used as flashlight.
4.has a front camera
Coolpad Roar
A front camera, also called secondary camera, can be used for video chats/selfies.
5.optical zoom

0x

The zoom range is the ratio between the longest and shortest focal lengths. A higher zoom range means that the lens is more versatile.
6.number of flash LEDs

1

Multi-LED camera flashes use LED lights which have different color temperatures (warm light and cool light), improving the color balance based on the conditions in which the photos are taken.

Audio

1.has a socket for a 3.5 mm audio jack
Coolpad Roar
With a standard mini jack socket, you can use the device with most headphones.
2.Has a radio
Coolpad Roar
A built-in FM radio tuner allows you to listen to most of the live-broadcasted FM radio stations without using the internet.
3.number of microphones

1

More microphones result in better sound quality and enable the device to filter out background noise.

Battery

1.battery power

1800mAh

Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.
2.has a removable battery
Coolpad Roar
The battery is removable and can be replaced by the user if broken.
3.Has an ultra power-saving mode
Coolpad Roar (Android 5.1 Lollipop)
The ultra power-saving mode, also called low power mode, is an effective way to extend the battery life of the device. Usually, it involves limiting screen brightness and contrast, disabling location services, restricting connectivity, and turning off nonessential apps.
4.has a battery level indicator
Coolpad Roar
An indicator shows you when the device has low battery.
5.has a rechargeable battery
Coolpad Roar
The battery can be recharged and used over again.

Features

1.Bluetooth version

4

Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
2.supports two SIM cards
Coolpad Roar
A dual-SIM mobile phone can work with two SIM cards at the same time.
3.is a multi-user system
Coolpad Roar (Android 5.1 Lollipop)
A multi-user operating system allows multiple users to access the device. Each user has a dedicated profile with apps and data available only to them.
4.The browser has word wrap
Coolpad Roar (Android 5.1 Lollipop)
