So, how can you tell the difference between healthy phone use and addiction?
The line isn't entirely clear. While using a mobile phone can make life much easier, unchecked usage can lead to phonoholism, or phone addiction.
Nomophobia/phonoholism (phone addiction) is a type of behavioral and emotional addiction involving compulsive use of a mobile phone. A person addicted to their smartphone feels a strong need to keep the device with them; otherwise, they become nervous and overexcited/restless.
