Apple iPhone 6s
The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.
2.weight

137g

143g

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.
3.thickness

9.3mm

7.1mm

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.
4.height

115.2mm

138.3mm

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

58.6mm

67.1mm

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

62.78cm³

65.89cm³

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

326ppi

326ppi

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

640 x 960px

750 x 1334px

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.
The bigger the screen size is, the better the user experience.
4.has an IPS screen
Apple iPhone 4
Apple iPhone 6s
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.
5.has a touch screen
Apple iPhone 4
Apple iPhone 6s
You can operate the device easily, by pressing the screen with your fingers.
6.Has Force Touch/3D Touch
Apple iPhone 4
Apple iPhone 6s
Devices using Force Touch or 3D Touch technology respond to the user's taps and presses with haptic feedback, and allow users to perform various actions depending on the force of the input.

Performance

1.CPU speed

1 x 0.8GHz

2 x 1.84GHz

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

0.5GB

2GB

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
Apple iPhone 4
Apple iPhone 6s
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.
The internal storage 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.Has integrated LTE
Apple iPhone 4
Apple iPhone 6s (Apple A9)
The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.
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.

Cameras

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.
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.
With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.
4.Has a dual-tone LED flash
Apple iPhone 4
Apple iPhone 6s
A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos.
5.has a BSI sensor
Apple iPhone 4
Apple iPhone 6s
A BSI (backside illuminated) sensor is a camera image sensor which captures better quality images in poor lighting conditions, and offers better overall sharpness and image quality.
When recording movies they stay focussed and sharp.

Audio

1.has a socket for a 3.5 mm audio jack
Apple iPhone 4
Apple iPhone 6s
With a standard mini jack socket, you can use the device with most headphones.
2.Has a radio
Apple iPhone 4
Apple iPhone 6s
