Specific Absorption Rate (SAR) The SAR rating shows the amount of electromagnetic radiation absorbed by the human body when using a mobile device, expressed in W/kg. Head SAR (EU) Cu certificare de protectie impotriva luminii albastre, ochii nu iti vor obosi chiar dupa mai multe ore petrecute pe telefonul mobil Xiaomi Redmi 9A. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoC

Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor. In India, the applicable limit for the head SAR is 1.6 W/kg per 1 g of tissue. Locally, the SAR levels are measured and certified by the Telecom Engineering Centre (TEC) or an internationally accredited lab. This means that the measured response time is worse than the average of all tested devices (21.8 ms). W-CDMA (Wideband Code Division Multiple Access) is an air interface used by 3G mobile networks. It is one of the three different UMTS interfaces together with the TD-SCDMA and the TD-CDMA. The standard provides faster data transfer speeds and allows more users to connect to the network simultaneously. Poti face selfie alaturi de prieteni, cu ajutorul palmei pe care o tii sus. Pur si simplu ridici palma in fata camerei si astepti sa fie imortalizat momentul.The battery type is determined by its structure and more specifically, by the chemicals used in it. There are different battery types and some of the most commonly used in mobile devices are the lithium-ion (Li-Ion) and the lithium-ion polymer battery (Li-Polymer). Pixels are usually measured in microns (μm). Larger ones are capable of recording more light, hence, will offer better low light shooting and wider dynamic range compared to the smaller pixels. On the other hand, smaller pixels allow for increasing the resolution while preserving the same sensor size. Audio file formats/codecs Mobile devices support various audio file formats and codecs, which respectively store and code/decode digital audio data. Audio file formats/codecs The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. Information about the set of instructions the processor can execute. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.

The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display. Audio Information about the type of speakers and the audio technologies supported by the device. Speaker Storage Every mobile device has a built-in storage (internal memory) with a fixed capacity. Storage Wi-Fi communication between devices is realized via the IEEE 802.11 standards. Some devices have the possibility to serve as Wi-Fi Hotspots by providing internet access for other nearby devices. Wi-Fi Direct (Wi-Fi P2P) is another useful standard that allows devices to communicate with each other without the need for wireless access point (WAP).USB The Universal Serial Bus (USB) is an industry standard that allows different electronic devices to exchange data.

Information about additional software and hardware features of the front camera which improve its overall performance. Camera frontala vine cu infrumusetare AI, astfel incat sa scoata in evidenta fiecare detaliu al frumusetii tale. The average temperature for the upper side under maximal load is 37.4 °C / 99 F, compared to the average of 32.7 °C / 91 F for the devices in the class Smartphone.Information about additional software and hardware features of the rear camera which improve its overall performance. Information about the sensor type of the camera. Some of the most widely used types of image sensors on mobile devices are CMOS, BSI, ISOCELL, etc. The SAR body rating shows the maximum level of exposure to electromagnetic radiation when the device is positioned against the body at the hip. The highest SAR value of mobile devices allowed in the US is set to 1.6 W/kg per 1 g of tissue. It is specified by the FCC and the CTIA follows whether the mobile devices comply with this standard.
