I have a friend who have issue with cellphone. His use makes him less efficient in his work. How can he manage the usage of his cellphone.

He can make cellphone use less disruptive by separating himself from the phone during focused work and setting deliberate times to check it.

• Turn off the phone and internet: Use a focused work block with the phone off and internet access blocked or Wi‑Fi turned off, so messages and browsing do not interrupt concentration. 1 2
• Put the phone out of reach: Leave it in another room or put it away; if that is not enough, give it to someone until a set time. 3 4
• Limit access during work hours: Set a specific period in the day when the phone stays elsewhere, then check it during planned breaks rather than whenever the urge arises. 5 6
• Take a real break after intensive work: After a focused work bout, step away and take a break rather than immediately adding more information or phone checking. 7
