Design
1.is dustproof and water-resistant
Samsung Galaxy S21 Ultra
Samsung Galaxy S21 Ultra (128GB / 12GB RAM)
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.
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.
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.
4.has branded damage-resistant glass
Samsung Galaxy S21 Ultra
Samsung Galaxy S21 Ultra (128GB / 12GB RAM)
Damage-resistant glass (such as Corning Gorilla Glass or Asahi Dragontrail Glass) is thin, lightweight, and can withstand high levels of force.
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.
Performance
1.CPU speed
1 x 2.9GHz & 3 x 2.8GHz & 4 x 2.2GHz (Samsung Exynos 2100)
1 x 2.9GHz & 3 x 2.8GHz & 4 x 2.2GHz (Samsung Exynos 2100)
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.
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 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
Samsung Galaxy S21 Ultra (Samsung Exynos 2100)
Samsung Galaxy S21 Ultra (128GB / 12GB RAM) (Samsung Exynos 2100)
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.
3.has built-in optical image stabilization
Samsung Galaxy S21 Ultra
Samsung Galaxy S21 Ultra (128GB / 12GB RAM)
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.
Audio
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.has a socket for a 3.5 mm audio jack
Samsung Galaxy S21 Ultra
Samsung Galaxy S21 Ultra (128GB / 12GB RAM)
With a standard mini jack socket, you can use the device with most headphones.
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.
Phones with physical keyboards have dedicated media keys, such as: play, stop, next, previous, volume up/down, etc.
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.
5.Has an ultra power-saving mode
Samsung Galaxy S21 Ultra (Android 11)
Samsung Galaxy S21 Ultra (128GB / 12GB RAM) (Android 11)
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.
An indicator shows you when the device has low battery.
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.
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.
NFC (near-field communication) allows a device to perform simple wireless transactions.
The device has a fingerprint scanner which identifies the user.
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.
Miscellaneous
DDR (Double Data Rate) memory is the most common type of RAM. Newer versions of DDR memory support higher maximum speeds and are more energy-efficient.
