The loss of his smartphone was a big blow for Xia Nan. The 31-year-old high-tech company worker from Beijing said he left his iPhone device in a taxi, turning his world upside down.

To be specific, mobile applications, rather than the handset itself, are the things that Xia really relied upon. Before he purchased his smartphone two years ago, he had an old Nokia feature phone that did not have any applications.

Smartphones, together with their internally installed mobile applications, have significantly changed the lifestyle of many Chinese people, according to a recent survey conducted by Beijing-based Horizon Research Group.Provided to China Daily

The day after he lost his modern device he forgot to attend a meeting, because he had got used to relying on it as a private secretary to remind him of such things. When he took the subway, he became bored because he could not watch TV dramas or read electronic books as he used to do during the one-hour trip.

Xia's girlfriend called him on his land line to join her for dinner at a restaurant after work. After the call, he was frustrated because instead of turning to his mobile phone, he had to use his computer to check the route on a map.

"I suddenly realized the importance (of those mobile applications) when I had to live without them," Xia said.

Smartphones, together with their internally installed mobile applications, have significantly changed the lifestyle of many Chinese people, according to a recent survey conducted by Beijing-based Horizon Research Group. Horizon research carried out its survey of 1,973 urban Chinese citizens aged from 18 to 32 in April.

Three out every 10 respondents said they have more than 20 applications on their mobile phones, while 22 percent of them said they have between 11 and 20.
