As the HomePod is here, Apple is dribbling out the details of what its first smart speaker will do including that it’s a power miser. The company posted environmental data showing that the HomePod uses no more than 9.25W of power when playing music at 50 percent volume. As MacRumors noted that’s less than the consumption of a typical LED light bulb (such as the 10W of a Philips Hue A19).
The speaker is not going to cringe at your electricity bill even if you play music at full volume and more importantly, the speaker consumed very little power when it is in idle mode. Apple said that the speaker draws a maximum of 1.76W in idle mode, or about 50 percent less than the latest Energy Star specs require. Apple says that it is the combination of “optimized power management features,” such as dropping into low-power mode after 8 minutes of inactivity, and a high-efficiency power supply.
How well does HomePod perform, than its competitors? Well, E Source observed that the original Google Home speaker used around 2W while idle and 3W while playing at high volume, while the initial Amazon Echo used 2.8W at idle and 7W at high volume.
That means, despite costly Apple speakers, you won’t be spending much on electricity for sweeter tunes.
