Sensor
The model of the sensor installed in the mouse. This information is indicated mainly for models equipped with high-end sensors, which are significantly superior in their capabilities to simpler solutions. Such characteristics are important primarily for gaming mice, so most of the devices for which the sensor model is specified belong to this category.
Knowing the name, you can find detailed data on the sensor and evaluate its capabilities. Note that one of the most popular brands nowadays, under which advanced sensors are produced, is
PixArt ; on the market are often found, in particular, sensors
PixArt 3212,
PixArt 3325,
PixArt 3327,
PixArt 3335,
PixArt 3360,
PixArt 3389,
PixArt 3395. The second common brand is
Avago (recently owned by the same PixArt); the most popular model of this brand is
Avago 3050, the simplest and most affordable representative of gaming sensors.
Sensor resolution
Resolution of the sensor responsible for tracking mouse movements on the work surface. Specified in DPI — dots per inch.
The physical meaning of DPI as a whole is as follows. The sensor of a modern mouse works on the same principle as the camera matrix, and consists of pixels. And DPI is the number of pixels that fall on 1 inch of the underlying surface (length or width), "visible" by the sensor.
It is believed that more DPI means a more advanced sensor and mouse in general; nowadays, models for
3500 – 5000 DPI,
12000 DPI,
16000 DPI even
more are not uncommon. In a way, it is — high resolution contributes to accuracy. However, the only thing that is directly determined by this indicator is the speed at which the cursor moves across the screen: the higher the resolution of the sensor, the greater the number of pixels that the cursor will move when the mouse itself moves a certain distance. At the same time, it is worth recalling that too high a speed is even more undesirable than too low. So the real need for high DPI (
1000 and above) arises mainly when working on large screens (4K resolution and more); for more modest displays (HD and Full HD), smaller values are often enough.
Max. acceleration
The greatest acceleration during movement, at which the mouse maintains normal performance; if this indicator is exceeded, the cursor may “break down” (moving to an unexpected place due to incorrect processing of data from the sensor).
The faster the mouse moves, the greater the acceleration acting on it. Accordingly, this parameter determines the sensitivity to sudden movements, the extent to which this model is able to normally perceive and process such movements. High values of maximum acceleration (
40 G,
50 G) are important first of all in dynamic games, especially for professional e-sportsmen and advanced enthusiasts. If the mouse is bought for relatively simple tasks (working with documents, surfing the web, etc.), you can ignore this indicator.
Max. polling rate
The polling rate shows how often the mouse sensor communicates with the computer about cursor movement. The parameter is measured in hertz (Hz), and one second is taken as a unit of time when evaluating it. The smoothness and speed of cursor movement directly depends on the sensor polling frequency. Directly related to this is the mouse response time - this is the time period during which the signal about the movement of the manipulator will reach the display of a change in the cursor position on the screen. Response time is measured in milliseconds (ms). The more hertz the mouse has, the shorter the response time it demonstrates.
Battery capacity
The battery capacity in a mouse affects how long it can operate without recharging and determines how often the device will need to be charged. Although manufacturers usually specify the operating time, the capacity helps assess the battery's resource under intensive use or when additional features, such as backlighting, are activated.
Battery life
Battery life of the mouse (see “Power”) on a single charge.
The battery life in this case is rather approximate: it is given for an average usage scenario, and the actual autonomy may turn out to be less or more than stated, depending on the usage patterns. Nevertheless, it is a fairly reliable indicator, allowing different battery models to be evaluated and compared with each other: the difference in the stated battery life usually correlates well with the actual autonomy difference.
Weight
The total weight of the mouse. For models with a wired connection, usually, it is indicated without cable, and for devices with weight adjustment (see above) — without weights.
This parameter is important primarily for professional gaming applications, although it is often relevant for ordinary users. Theoretically, less weight promotes speed and reduces fatigue. At the same time, in fact, much depends on the personal habits and preferences of the user: a mouse that is too light may “not be felt in the hands” and not give familiar feedback. Therefore, although most mice have a lower weight limit of
60 – 80 g, however, even among professional gaming models there are much more massive devices —
120 – 140 g or
more. The lightest variety of "rodents" is laptop (see "In the direction"), among them devices come across and
less than 60 g.
Also note that the weight to some extent depends on the size and “tricked out” of the device, but there is no unambiguous dependence here: models similar in size and functionality can differ markedly in weight.
