Editing Optical mouse (section)

== Power ==
Manufacturers often engineer their optical mice—especially battery-powered wireless models—to save power when possible. To do this, the mouse dims or blinks the laser or LED when in standby mode (each mouse has a different standby time). A typical implementation (by [[Logitech]]) has four power states, where the sensor is pulsed at different rates per second:{{Citation needed|reason=From a quick google search, the only place these numbers show up is in this article.|date=April 2018}}

* 11500: full on, for accurate response while moving, illumination appears bright.
* 1100: fallback active condition while not moving, illumination appears dull.
* 110: standby
* 12: sleep state

Movement can be detected in any of these states; some mice turn the sensor fully off in the sleep state, requiring a button click to wake.

Optical mice utilizing infrared elements (LEDs or lasers) offer substantial increases in battery life over visible spectrum illumination. Some mice, such as the Logitech V450 848&nbsp;nm laser mouse, are capable of functioning on two AA batteries for a full year, due to the low power requirements of the infrared laser.{{Clarify|date=September 2011|reason=moving all year? full on but not moving? standby?}}

Mice designed for use where low latency and high responsiveness are important, such as in playing [[video game]]s, may omit power-saving features and require a wired connection to improve performance. Examples of mice which sacrifice power-saving in favor of performance are the [[Logitech G5]] and the [[Razer USA Ltd|Razer]] Copperhead.
