Information about the communication technologies supported by the device and their respective uplink and downlink bandwidth. The sound shouldn't be good enough even for less demanding natures, it is very high frequency-heavy and not very defined. Tracking/Positioning Information about the positioning and navigation technologies supported by the device. There are also non-satellite technologies for locating mobile devices such as the Enhanced Observed Time Difference, Enhanced 911, GSM Cell ID.
Larger ones are capable of recording more light, hence, will offer better low light shooting and wider dynamic range compared to the smaller pixels. The frequency of 1562Hz is quite high, so most users sensitive to PWM should not notice any flickering. Sensors Different sensors measure different physical quantities and convert them into signals recognizable by the mobile device. It is also pleasing that quite a few LTE networks are supported, so you can use the Blackview A80 Plus to access the mobile Internet even when traveling further abroad.Nevertheless, the Blackview A80 Pro achieves decent runtimes: 15:43 hours in our Wi-Fi test speak for several days away from the power outlet. The Blackview A80 Pro wants to convince us with a huge battery, numerous LTE bands and a quad-cam on the back. 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. The CPU bits are determined by the bit-size of the processor registers, address buses and data buses. The loudspeaker, on the other hand, is of poor quality, and the extreme blue cast in the display is also disturbing.
It could get uncomfortable in very high ambient temperatures, but we do not see any problematic heating otherwise. The higher the pixel density, the more detailed and clearer is the information displayed on the screen.Videos can be recorded in Full HD with 30 fps at most, but brightness transitions and autofocus are very slow.
The standard provides faster data transfer speeds and allows more users to connect to the network simultaneously.Overall, the Blackview A80 Pro offers a bit more power, but you will hardly notice that in everyday use. Since 2018 I have been Managing Editor for mobile device reviews, working alongside my colleague Daniel Schmidt. Thus, there is no separate black and white lens as in some Huawei cell phones and also no hybrid optical zoom. Paired with 64GB of storage, it allows you to work more, play more, share more and at the same time plug in less.
In the lab with very good exposure, the autofocus has clear problems, the contrasts also vary depending on the image area, but overall they are not that bad. With its glossy surface and gradient color on the back, the smartphone looks quite chic, but it is also quite susceptible to fingerprints. The battery lasts 15:52 hours, which is a decent value, but given the high capacity of 4,680 mAh, more would have been possible. There are different battery types and some of the most commonly used in mobile devices are the lithium-ion (Li-Ion) and the lithium-ion polymer battery (Li-Polymer). Sometimes one and the same model may is offered in variants with different internal storage capacity.If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether. The Blackview A80 is available in black, blue or red, with all but the black model offering a gradient color on the back. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). The touch screen gives no reason for criticism: The smartphone can be operated without any problems. Charging is only possible with a maximum of 10 watts, so it can take up to 2 hours until the battery is full again.
