According to a study by Women at NBCU, women and men say they couldn't live without the internet or sleep for a month, but when asked for a third item they couldn't live with out, men chose ‘sex', while women chose ‘showers'.

In fact, about 54 percent of women own smartphones compared with 46 percent of men. Women also tend to have more friends on social networking sites and follow more brands, and check their profiles about four or five times a day.

Meanwhile, females are also becoming more interested in gaming. Although men have traditionally dominated the gaming world, a whopping 75 percent of women with smartphones own a gaming app compared with 67 percent of men.
