Design

The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.

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

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.

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.

OLED (Organic Light-Emitting Diode) displays are formed of organic materials that emit light. They have higher contrast ratios and wider viewing angles compared to LCDs. AMOLED and POLED are types of OLED displays.

You can operate the device easily, by pressing the screen with your fingers.

Sapphire crystal glass is an extremely durable material, which is surpassed only by diamond in terms of hardness. A sapphire crystal display is stronger and more scratch resistant than toughened glass such as Corning Gorilla Glass.

An e-paper display provides a high contrast allowing users to read in direct sunlight without requiring much power.

Performance

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.

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

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.

Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the 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 960fps.

Audio

Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.

A built-in FM radio tuner allows you to listen to most of the live-broadcasted FM radio stations without using the internet.

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

Battery

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.

The manufacturer offers a branded wireless charging kit. To charge the device, you simply put it down on its charging base.

Fast charging technologies, like Qualcomm’s Quick Charge or MediaTek’s Pump Express, are used to reduce the time it takes to charge a device. For example, with Quick Charge 3.0, the battery can be charged to 50% in just 30 minutes.

The battery is removable and can be replaced by the user if broken.

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.

Features

The download speed is a measurement of the internet connection bandwidth, representing the maximum data transfer rate at which a device can access online content.

2.has NFC

✖Samsung Galaxy A11

✔Samsung Galaxy A21

NFC (near-field communication) allows a device to perform simple wireless transactions, such as mobile payments. Note: this feature may not be available in all markets.

802.11ac wireless works on the 5GHz frequency range. It offers higher transfer rates, improved reliability, and improved power consumption. It provides advantages for gaming and HD video streaming.

All DLNA-certified products are compatible with one another. When different devices are connected to the same network, data can be transferred easily between them.

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.

The upload speed is a measurement of the internet connection bandwidth, representing the maximum data transfer rate at which a device can send information to a server or another device.

A21 samsung vs a11

galaxy-a51

Samsung introduced six new phones to its popular Galaxy A series on Wednesday. There are two 5G phones and four 4G phones. Two of the four 4G phones will be available starting Thursday. The base Galaxy A01 phone will be available in the US for $110 (about £90 or AU$180) along with the A51 LTE phone, which costs $400 (£329, AU$599). International pricing details aren't yet available for all models, but the 4G LTE versions of the A51 and A71 are already on sale in the UK and Australia. The 5G models will cost £429 for the A51 and £519 for the A71, which converts to about AU$850 and AU$1,030 respectively.

The Galaxy A01 is the smallest and cheapest of the new phones. It features a 5.7-inch HD display, offers 16GB storage and 2GB RAM. It has a dual-camera setup led by a 13-megapixel rear camera and a 3,000-mAh battery. Meanwhile, the LTE version of the Galaxy A51 has a 6.5-inch HD display, 128GB of storage and 4GB RAM. It's also got a four-camera setup led by a 48-megapixel sensor, and a 4,000-mAh battery. It has a more modern design and a less noticeable notch than the A01. At $400 (£329, AU$599), it's the most expensive 4G phone in this year's Galaxy A Series.

Based on the specs sheet, the two phones don't have much in common. But both have the option to expand your storage by 512GB and the presence of headphone jacks, which is something that appears in all six of the 2020 Galaxy A phones.
