Myth: I shouldn’t keep my phone plugged in overnight
Truth: Smart technology stops your phone from charging after it’s full. If the battery drops back down to a certain point when it’s still plugged in, the phone knows to start charging again, says Sergio Flores, electronics engineer for Samsung. “This way, even if you are charging your phone overnight, the phone is only being charged when it is necessary,” he says.
Myth: Might as well always leave my phone on efficiency mode
Truth: Keeping your phone on low-power mode after it’s charged won’t harm the software, but it might lead to poorer user experience. “Phones are designed to be really flashy and give you an over-the-top experience,” says Brad Nichols, technician with technology repair service company Staymobile. “When you turn them into that efficiency mode, it gets rid of all the redundant things.” Low brightness might make the screen hard to see, and you might notice the sound isn’t as loud as you like. Plus, apps might only check for notifications every ten minutes or so, so you won’t get the instant feedback you’re used to, says Nichols.
Myth: My phone is totally safe in a public charging port
Truth: Using a public port could put your information at risk. Unlike the typical socket you’d plug your charger into, those cords you see at restaurants and airports create an easy path to transfer data. “People don’t realize they’re not just a power source,” says Eva Velasquez, CEO and president of Identity Theft Resource Center. “It’s not like plugging your lamp into the wall.” Hackers could potentially access anything in your phone—emails, texts, photos, and more. If you need to charge your phone in public a lot, a portable charger is a much safer option, says Velasquez.
