An unplugged thing cannot use electricity. Even if an appliance is turned off, it can still draw power and have you spend more on the electricity. It’s the same with chargers—they consume power even if they’re not charging a device. When not in use, the phone and laptop charger will draw power. It may not seem like a lot, but the minor aspect can cost you 8% of your home’s annual electricity. Unplugging anything that you don’t use is one sure way to reduce your electricity bill.
