81.0% of people in Germany check their smartphones or other digital devices at least once or twice an hour – even when they haven’t received a specific notification. 47.1% of people check their devices as often as 3 times an hour or more, while 12.4% always keep their device within reach.
There is a clear split across age groups: the younger the respondent, the more often they check their smartphones and other devices. 90.6% of 16- to 30-year-olds check their digital devices at least 1 to 2 times per hour; 68.1% check them at least 3 times per hour.
Question: On average, how often do you check your digital devices (e.g. smartphone, tablet, laptop, smartwatch), even when you haven’t received a specific notification?
What’s behind the continual screen-time? One possible reason: sheer habit. 71.3% of people in Germany check their digital notifications and apps for no particular reason. Experts refer to this behaviour as a habit loop (see quote below).
Here too, the figures from the representative IU study show that: the younger the respondents, the more common this digital habit is. For people between the ages of 16 and 30, the figure stands at 79.6%.
Question: To what extent do you agree with the following statement? “I check my digital notifications or apps out of habit, for no particular reason.”

Focus
Digital devices are a constant companion for people in Germany throughout the day. For many people, they are part of their morning and evening routine – and for the majority, having their mobile phone within reach is a given when doing other activities, such as eating. This is particularly true of young people.
Whether they’re eating, chatting or watching TV, 62.8% of respondents use their smartphone whilst doing other things. For young people aged 16 to 30, the figure is 73.1%; among those aged 31 to 45, it is 69.5%.
Question: To what extent do you agree with the following statement? “I use my smartphone while doing other things (e.g. while eating, chatting, watching TV).”
Excerpt from the statements included in the survey; only respondents who have a smartphone
75.1% of respondents say they use digital devices within 30 minutes of waking up. More than a third reach for their smartphone, tablet, laptop or smartwatch immediately after waking up.
Among 16- to 30-year-olds, the figures are significantly higher than the average for the German population. 86.9% of them reach for a digital device within 30 minutes of waking up, and 50.4% do so immediately after waking up.
Question: How long after waking up do you first use a digital device (e.g. smartphone, tablet, laptop, smartwatch)?
73.8% use their digital devices less than 30 minutes before going to bed; 2 in 5 do so right before going to bed. Only 1 in 10 people follow the general recommendations on sleep hygiene¹ and put their mobile phones and other devices away at least an hour before going to bed.
The figures for people aged up to 30 are particularly striking: 86.3% use their digital devices less than 30 minutes before going to bed; 55.9% do so right before falling asleep.
Question: When do you last use a digital device (e.g. smartphone, tablet, laptop, smartwatch) before going to bed?
