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.
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 display supports HDR10, which is an HDR (high dynamic range) video technology. Compared to standard dynamic range (SDR) video, HDR10 video has greater contrast and color depth, resulting in more realistic images.
The display supports HDR10+, which is an improved version of HDR10 video technology. HDR10+ uses dynamic metadata so that each frame can have its own settings for contrast, brightness, and colors, which results in lifelike images.
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.
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.
AnTuTu is one of the most important benchmarks for Android devices. The score reflects the overall performance of a device by summing up results of individual tests that various parameters, such as RAM speed, CPU performance, 2D & 3D graphics performance.
Wild Life is a cross-platform benchmark developed by 3DMark that tests the graphical performance of a device (using the Vulkan API on Android/Windows and the Metal API on iOS). The Unlimited version runs off-screen so that factors such as display resolution don’t affect the score. Source: 3DMark.
Wild Life is a cross-platform benchmark developed by 3DMark that tests the graphical performance of a device (using the Vulkan API on Android/Windows and the Metal API on iOS). The Extreme version is much more graphically-demanding than the standard Wild Life benchmark. Source: 3DMark.
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.
With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.
On-device machine learning is used to recognize people, places, and more in the Photos app. The algorithms run on the device, where this sensitive data is then kept. Competing services upload the photos and perform this on their servers, which requires the sharing of personal data.
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.
Charging speeds are expressed in watts (W), a measure of electrical power. A higher wattage results in a faster charging speed. In order to achieve the advertised charging speed, it is important to use a compatible charger.
Charging speeds are expressed in watts (W), a measure of electrical power. A higher wattage results in a faster charging speed. In order to achieve the advertised charging speed, a compatible wireless charger must be used.
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.
LDAC is a codec developed by Sony for Bluetooth audio. It is capable of a very high bitrate of 990kbps, which provides high resolution audio. It can also automatically adjust to a lower bitrate of 330kbps or 660kbps to increase stability.
aptx Adaptive is an audio codec for Bluetooth devices that is developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps), which means it can adjust the bit rate for different scenarios, such as listening to HD audio or reducing interference from other devices.
