Over the years, a combination of policies and technologies has successfully reduced the amount of power used by devices and appliances when in standby power mode, but these energy savings have been offset by an increase in the number of products drawing standby power and new power requirements for maintaining network connections.
By 2010, regulations were in place in most developed countries restricting standby power of devices sold to one watt (and half that from 2013). Standby power is electrical power used by appliances and equipment while switched off or not performing their primary function, often waiting to be activated by a remote controller.
Standby power may be used to power a display, operate a clock, etc., without switching the equipment to full power. Battery-powered equipment connected to mains electricity can be kept fully charged although switched on; for example, a mobile telephone can be ready to receive calls without depleting its battery charge.
The primary driving factor in the maximum battery capacity of a control unit is the capability of the charger to meet the 48 hour recharge requirement. Even if the charger is capable of meeting the 48 hour recharge requirement, the physical size of the larger amp-hour batteries may exceed the physical dimension for panel cabinet.
Standby power consumption can be estimated using tables of standby power used by typical devices, although standby power used by appliances of the same class vary extremely widely (for a CRT computer display standby power is listed at a minimum of 1.6 W, maximum 74.5 W).
