How Much Time Have You Spent on Your Phone?

Short answer: at the UK adult average of 3¼ hours a day, 24 years of phone use adds up to about 3¼ years of round-the-clock time. Pop in your own daily minutes and starting age below.

How much time have you spent on your phone?

Phone time is unusually well measured and unusually poorly remembered. A screen can report three hours while a day still feels empty of them. This experiment takes the daily minutes you type, starts from the age you first used a phone like this, and multiplies. The default of 180 minutes is a round three hours, not a moral benchmark. ONS time-use figures treat computers and digital devices as their own slice of the day; they do not decide whether those minutes were messages, maps, novels or nothing much. Lower the start age if a childhood hand-me-down counts. Raise the minutes if the weekly average is higher than the figure you wish it was. You can switch to television too, or count both screens together.

What does that mean?

180 minutes a day from age 14 to 32 is 2 years and 91 days — 7% of the life lived so far. Some of that will have been useful, some not; the model cannot tell the difference and does not try.

A habit measured in minutes, stored in years

Three hours a day is 21 hours a week, which is already more than many part-time jobs. Stretch that from age 14 to 32 and the total crosses a year of clock time. The arithmetic is the same as for sleep or television; only the label on the hours changes. If your current week is a spike, use a calmer average rather than yesterday.

The average is not you

Surveys of UK adults produce one picture of device use; your lock-screen report produces another. This page prefers the second. National time-use numbers are here so the default is not invented, not so we can tell you that you are above or below a healthy line. There is no healthy line on this calculator. Minutes are minutes.

Screens compete with everything else

Phone hours overlap with commuting, television and lying in bed, so you should not add every experiment on this site into one grand total without noticing the double counting. If a commute is also scrolling, pick a home for those minutes. The extra-hour experiment is there for the version of this number you would like to be smaller.

Television adds up the same way

Switch the screen to television and the sum is identical; only the habit changes. ONS time-use surveys still find watching TV one of the largest leisure blocks in a UK adult’s day, at more than two hours. Two hours a day from age ten to 32 is close to two years of clock time. People remember favourite series and forget years of news, sport and something on in the background over dinner, so an average catches more than a list of shows. If phone video has replaced the TV for you, count those minutes once, under whichever screen you use most. To add the two together, choose phone and TV and enter the combined daily minutes.

Worked example: the UK average

Ofcom found that in May 2024 UK adults spent 4 hours 20 minutes a day online, 3 hours 15 minutes of it on a smartphone.

  1. 3 hours 15 minutes a day is about 1,187 hours a year.
  2. From age 16 to 40 (24 years) that is about 28,500 hours.
  3. 28,500 ÷ 24 ÷ 365.25 ≈ 3.25 years of round-the-clock time.
  4. Young adults use more: 18 to 24-year-olds averaged 6 hours 1 minute a day online across all devices.

At the UK adult average of 3¼ hours a day on a smartphone, 24 years of use adds up to about 3¼ years of continuous time.

What people get wrong

“My screen-time figure is all scrolling.”
It includes maps, calls, messages, music and reading. Ofcom found that almost half of UK adults’ online time is spent on services owned by Alphabet and Meta, which includes Google search, YouTube, WhatsApp and Facebook.
“Phone time and TV time are separate.”
Many people now watch video on their phone, so the two overlap. Count each minute once, under whichever screen you use.
“Yesterday’s figure is a good guide.”
Daily use swings a lot. A weekly average from your phone’s own report is a better number to use here.

Common questions

How many hours have I been on my phone today?

Your phone will tell you. On an Android phone, open Settings and then Digital Wellbeing & parental controls. On an iPhone, open Settings and then Screen Time. Both also show a weekly average, which is the better figure for this calculator.

How much time does the average person spend on their phone?

Ofcom’s 2024 research found UK adults spent 3 hours 15 minutes a day online on smartphones, out of 4 hours 20 minutes online across all devices.

How we calculated this

Hours = (current age − age you started) × 365.25 × (minutes a day ÷ 60). Days and years of clock time follow from 24-hour days. The share of life uses age × 365.25 × 24 as the denominator. Use while walking, at work or in bed is not split out.

Assumptions and limitations

This is a simplified estimate. Actual results depend on factors the model does not include.

  • Daily minutes are treated as constant from the start age to now.
  • Overlapping uses — maps on a train, videos in front of a television — are not separated.
  • A year is 365.25 days.
  • The default three hours is a round starting point, not an official UK average applied to you.
  • Time with the screen off, or a phone used only as a clock, is ignored.
  • If start age is at or above current age, the total is zero.
