I don’t see why energy labels move the needle for phones and tablets, considering battery life is already a highly maximized and sought after feature.
An appliance plugged into a wall is different as most people have no easy way to discern energy usage. But they are reminded everyday of their mobile’s energy efficiency.
And no one is going to use a black and white mobile to save 100kWh per year.
Estimates for the numbers are right there (which I really appreciated).
I think the main expected gains here are less from the estimated 0.2% electricity savings and more about longer average product lifetimes (thanks to better repairability).
If a manufacturer gets his phone to last for a day of heavy use, there is little motivation to improve efficiency past that benchmark I think (and this labeling provides that).
