In mobile handsets, if we keep our Bluetooth connection on for a long period of time then its battery runs out of charge within few hours. The obvious reason for this battery going out of charge is that the Bluetooth connection needs continuous power supply and it can also be experienced with our mobile handsets as well. Hence, if the battery is running out of charge then user needs to replace the battery of those wireless keyboards so as to get the connection going and use the input device in an efficient manner.

The basic necessity of a Bluetooth technology is that it requires continuous power so as to keep the connectivity working between the keyboard and CPU of any computer. Logitech has several wireless keyboards and they have batteries inside them which help to operate the Bluetooth mechanism by which the input activity takes place.
