Brits who charge mobile phones and tablets overnight waste £135m a year
The amount of electricity wasted would be enough to power a city the size of Canterbury for over a year
BRITS waste around £135million a year charging mobiles overnight, researchers claim.
Most smartphones and tablets take around two hours to charge up.
But tests show that a fully-charged device continues to draw power equal to two thirds of what it has already received.
It costs roughly one penny to leave a phone on charge overnight and slightly more for a tablet.
The soaring number of devices costs the average household £33 a year in electricity.
Department for Energy figures suggest the country spent £900 million charging devices in 2015 — enough to power both Birmingham and Bradford for a year.
With around 50 million smartphones and 15 million tablets in Britain, just half left charging overnight would waste about £135million of energy.
