If you have an iPhone 6S, 7, or 7S, you might be tempted to plug in your iPhone charger anywhere and everywhere when you're low on battery power. Resist that urge — there are two places you should never, ever charge your iPhone — doing so could result in your data and privacy being breached.
Someone Else's Computer
You're working at your local coffee shop and realize your iPhone battery is low. You forgot your own charger, but the nice person sitting next to you has his. What's the harm in asking for a favor and requesting that you be allowed to charge your phone on a stranger's computer?
Well, chances are that nice stranger will simply lend you a charge. But you're also leaving yourself wide open to having your personal information and photos stolen. When you plug in your device to an unrecognizable computer, a pop-up asks the user if this computer is trusted. Simply clicking "yes" gives the computer user access to your photos and other information.
Don't Use A Third-Party Charger
Charging your iPhone at the airport or any other place where there's a third-party charger is not a great idea. Any charger that isn't an Apple MFI certified lightning connector could drain and ultimately ruin your battery. In the rare case of an exploding iPhone battery, Apple will likely be able to tell that you didn't use an Apple-approved charger — which can affect your warrranty. Play it safe by investing in Apple chargers.
