Parents of under-18s are set to spend an average 88 hours on unintended phone scrolling over the summer holiday, a survey suggests. More than half of children aged eight to 16 (56%) say their parents' phone use causes them to miss important family moments, while 63% believe their parents do not realise how much time they spend on their phones, the survey for Virgin Media O2 found. An 18-month study involving 16,000 people by the media giant found parents of under-18s spend more than two hours a day using their smartphones unintentionally, and are significantly more likely than non-parents to fall into unintentional smartphone habits. More than three quarters of parents of under-18s (76%) said they often picked up their phone without thinking, compared with 57% of non-parents. Virgin Media O2 has launched a "digital intentionality score" to allow people to understand how they use their phones, and compare their behaviour against the national average of 63 out of 100 – with higher scores representing more intentional use.
