Answer:
41%
Step-by-step explanation:
I couldn't find very recent surveys but a Gallup poll carried out 5 years ago (2015) found out that 41% of men and 51% of women answered that they couldn't live without their smartphone. On an earlier poll carried out on 2006 only 32% of the men said that they couldn't live without their cellphone which means a 9% increase in 9 years. That shows us that the tendency for smartphone dependency is increasing and probably now more than 50% of men would agree with the question.
