quiet click
This feature means that the mouse keys, when pressed, sound much quieter than most "rodents". This is not necessarily completely silent operation — the sound may be present; but there are also absolutely silent models. Anyway,
"quiet click" can be a real lifesaver in situations where normal button clicks are undesirable — for example, if the mouse has to be used intensively at a late time, or if the user or others are very annoyed by clicks. However, note that the presence of a quiet click is indicated based on the manufacturer’s statements, and different brands may invest different meanings in the concept of “quiet”. So if the minimum noise level is critical for you, you should clarify the features of the selected model from additional sources, for example, video reviews or reviews.
Battery life
Battery life of the mouse operating on replaceable power elements (see "Power") with one set of batteries.
The mentioned operating time is quite approximate: it is specified for an average usage mode. Actual battery life may be either less or more than stated, depending on the usage characteristics; moreover, the quality of the battery brand also greatly affects the operating time. Nevertheless, it is a fairly reliable indicator, which can be used to evaluate and compare different models: the difference in the stated operating time generally corresponds to the difference in actual battery life when using batteries of similar quality.
It is worth mentioning that modern battery-operated mice have fairly substantial battery life, measured in months; in the longest-lasting models, the stated operating time is about 36 months (or 3 years).
