What is the difference between nokia lumia 820 and 900

Focal length - The lower shorter the focal length number, the wider the shot will be. Conversely, longer focal length cameras produce narrower frames, which can be used for telephoto zoomed-in purposes. Location - This field shows the positioning systems supported by the device.

Every wireless phone device that is sold in the U. Date approved - Shows the date when the particular phone is approved by the Federal Communications Commission.

These limits are given in terms of a unit referred to as the Specific Absorption Rate SAR , which is a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone.

Write a review. Design 1. 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. 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. The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability. The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.

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 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.

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. Damage-resistant glass such as Corning Gorilla Glass or Asahi Dragontrail Glass is thin, lightweight, and can withstand high levels of force. It was designed to overcome the main limitations of conventional twisted nematic TFT displays: limited viewing angles and low-quality color reproduction. They have higher contrast ratios and wider viewing angles compared to LCDs. You can operate the device easily, by pressing the screen with your fingers.

Performance 1. RAM 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. CPU speed 2 x 2GHz.

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores processing units. Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen.

Damage-resistant glass such as Corning Gorilla Glass or Asahi Dragontrail Glass is thin, lightweight, and can withstand high levels of force. They have higher contrast ratios and wider viewing angles compared to LCDs. You can operate the device easily, by pressing the screen with your fingers. The device can display 3D images without the need for wearing special glasses.

The display's special construction allows viewers to get a sense of an image's depth by tailoring its position to fit the user's perspective. Performance 1. RAM 0. 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.

CPU speed 1 x 1. 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.

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.

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 1. 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 maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.

A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos. 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.

Slow-motion is an artistic video effect that makes time seem to go slower. It is achieved by recording a video at a higher frame-rate than the standard playback rate of 24fps or 30fps.

Depending on camera capabilities, frame rates for slow-motion videos vary between 60fps and fps. It can automatically shoot pictures with a higher dynamic range HDR.
