Brightness

The maximum brightness in nits that the screen of the device produces.

The high-brightness displays remain legible under intense ambient light, which is important for quickly retrieving information from the dial outdoors on a clear sunny day. However, a large margin for this parameter affects the cost and power consumption of the display, which reduces the battery life of a wearable device.

CPU model

The model name of the processor (CPU) installed in the watch. Knowing this name, you can find detailed data on a particular CPU and evaluate its level and general capabilities. This is especially important due of the fact that these capabilities depend not only on the basic specs (number of cores, clock frequency), but also on specific design nuances.

Memory storage

The amount of own storage provided in the design of the watch/bracelet. This memory is used for permanent storage of various information: call log, received SMS and other messages, additional applications, data on physical activity for a certain time, etc. The larger its volume, the more data can be stored in the device without the need to clean it to free up space. On the other hand, in the operation of smartwatches, large volumes ( 64 GB, 32 GB, 16 GB, even 8 GB and 4 GB) are not always required, capacious drives are quite expensive, and replaceable cards installed in corresponding slot (see below).

Battery capacity

The capacity of the battery that is installed in the gadget.

Theoretically, the higher the capacity, the longer the battery can work on a single charge. However, in fact, the battery life of the gadget also depends on its power consumption, and it is determined by the specs of the display and the hardware. Therefore, only models of the same type with very similar specs can be compared in terms of battery capacity; and for an accurate assessment of battery life, it is better to focus on the directly claimed operating time in one mode or another (see below).

It is also worth mentioning that high-capacity batteries inevitably turn out to be quite heavy and bulky. So the capacity of batteries installed in wearable gadgets is also greatly limited by size and weight.
