As soon as it is available for the One Mini 2 I will revisit the handset and update this review - so stay tuned!

Information about additional software and hardware features of the rear camera which improve its overall performance. The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening. That said, the One Mini 2 managed to run all the games and applications I threw at it, and apart from some tardy load times operation was smooth throughout. 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. Battery The batteries of mobile devices differ in capacity and technology. They provide the electrical charge needed for the functioning of the devices. Capacity

The HTC One mini has a lot going for it and there are precious few phones that can make a better first impression. One thing that raises a flag though is price. It would have been difficult to swallow even with the bells and whistles of the One (M8) - in comparison, a Snapdragon 800-powered, water-resistant Xperia Z1 Compact with a 20.7 MP camera will run you much less. 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. stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 3G mobile network.

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. Information about the electric current (amperes) and voltage (volts) the charger outputs. The higher power output allows faster charging.

Accelerometer, gyroscope, digital compass, proximity sensor, ambient light sensor, Voice dialing, Voice commands, Voice recording Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology

It's also worth noting that the HTC Desire 816, a handset which will slide in below the One Mini 2, sports a punchier 1.6GHz quad-core processor and a Geekbench 3 average of 1463.Information about the number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well.
