Don’t charge your phone in public places for safety reason.

Researchers now argue that public charging ports may be hacked and can allow hackers to collect all the information they can get while your phone is plugged in.

“Just by plugging your phone into a [compromised] power strip or charger, your device is now infected, and that compromises all your data,” says Drew Paik of security firm Authentic8.

Public charging ports and WiFi hot spots are commonly found in places such as airports, conference centers and parks to help people have access to their phones and data at all times. However, using these unknown ports can be very risky.
