O Xiaomi Redmi Note 8 Pro (128GB) é um bom celular Android com processador de 2.05GHz Octa-core que possibilita executar jogos e aplicativos pesados.
Information about the maximum number of frames per second (fps) supported by the rear camera while recording video at the maximum resolution. Some of the main standard frame rates for recording and playing video are 24 fps, 25 fps, 30 fps, 60 fps.
This SAR rating shows the maximum level of exposure to electromagnetic radiation taken when the device is placed next to the ear. The applicable limit for the US is 1.6 W/kg per 1 g of tissue. In the US the FCC tests and sets the SAR limits for all mobile devices, which are controlled by the CTIA.
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.
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.
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.
Xiaomi's Redmi Note 8 series is now official, and there's a lot to like. Both phones have quad cameras at the back, fresh new designs, and offer great value for what they cost. The Redmi Note 8 Pro in particular stands out due to its 64MP camera — a first for the manufacturer — and the Helio G90T platform. The Redmi Note 8, meanwhile, is powered by the Snapdragon 665 and has a 48MP shooter at the back.
This SAR rating shows the highest level of exposure to electromagnetic radiation measured when the device is placed at the hip level. The top SAR value for mobile devices used in Europe is limited to 2 W/kg per 10 g of tissue. This standard follows the ICNIRP Guidelines 1998 as well as the IEC standards and is determined by the CENELEC.
Bluetooth uses various profiles and protocols related to faster exchange of data, energy saving, better device discoverability, etc. Some of those supported by the device are listed here.
GSM (Global System for Mobile Communications) was developed to replace the analog cellular network (1G), therefore it is referred to as a 2G mobile network. It has been improved with the addition of General Packet Radio Services (GPRS) and later via the Enhanced Data rates for GSM Evolution (EDGE) technology.
GPU is a graphical processing unit, which handles computation for 2D/3D graphics applications. In mobile devices GPU is usually utilized by games, UI, video playback, etc. GPU can also perform computation in applications traditionally handled by the CPU.
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.
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.
A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel.
CDMA (Code-Division Multiple Access) is a channel access method for communications within mobile networks. Compared to other 2G and 2.5G standards like GSM and TDMA, it provides increased data transfer speeds and allows more subscribers to connect simultaneously to the network.
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.
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.
Then again, you can say the same for the telephoto. The 64MP sensor could very well be enough for more than decent 2x stills, so why would anyone need a dedicated lens when you have so many pixels to work with? Let's delve deep into the phone itself and try to answer the questions at hand.
There are several network technologies that enhance the performance of mobile networks mainly by increased data bandwidth. Information about the communication technologies supported by the device and their respective uplink and downlink bandwidth.
One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions.
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).
Packing the brand new Helio G90T chipset along with a huge 4,500 mAh battery with fast charging and a quad-camera setup on the back, the Redmi Note 8 Pro has all that it takes to be a competitive handset. At first glance, performance is comparable to flagships from last year while the camera setup aims to provide a versatile experience on the cheap.
Ótima conectividade deste aparelho que inclui Bluetooth 5.0 + A2DP/LE, WiFi 802.11 a/b/g/n/ac [wifi5] (2.4GHz, 5GHz) + MIMO e NFC para pagamentos por aproximação ou conexão com outros dispositivos.
