RAM

The amount of random access memory (RAM) installed in the gadget.

This parameter is one of the key ones for the overall performance of the system: the more RAM, the faster the device works, the easier it is to handle tasks with high hardware requirements and the wider the set of applications that the gadget is able to run. Note that a large amount of RAM can compensate for even a relatively weak CPU. At the same time, you need to remember that different operating systems (see above) have different requirements for RAM and features of its use; therefore, only models on the same software platform can be compared by this indicator.

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.
