If you frequently use activity or health apps on your iPhone to record the number of steps you walk each day, then your performance may be better than you think. A study by the University of British Columbia found that iPhone underestimated the number of people's steps - about 21.5% less.

The study measures the iphone with the gold standard for measuring the number of steps: a waist-waist pedometer as a target for comparison. The team also conducted lab tests where the number of walking steps on the treadmill was manually calculated to provide absolutely accurate data results.

Their discovery is very interesting. In the lab environment, iPhone's test accuracy dropped by less than 5% when testers used faster walking speed - this floating level is considered acceptable even in a dedicated pedometer of.

However, when testers began to adopt slower walking speeds, iPhone calculated 9.4% fewer steps. In real life, the iPhone missed 21.5% of the steps - an average of less than 1340 steps per day.

The research team said that the reason why less than so many steps count, in addition to walk the iPhone without statistical steps, people at home or work will not have been carrying the phone has a certain impact, for example, we often go to the toilet And pouring water next to the dispenser, one day will be repeated many times, but not necessarily bring the phone with him.

The good news, however, is that the study found that the number of inaccurate steps drawn is often less than the actual number of steps, rather than exaggerating the number of steps.

Mark Duncan, lead author of the study, said: "For those who are already tracking their steps, they can be assured that they might get more help if their handsets reach the recommended 10,000 paces a day , And this is also helpful to their efforts to improve their health and from a public health perspective it is far better than exaggerating the number of steps. "

The study was published in Sports Science magazine.
