Remember counting down until your two-year smartphone plan was up so you'd be eligible for an upgrade? These days, you probably wait as long as possible before getting a new one.

Mobile phone service providers want you to trade up every other year, but a new survey from carrier Ting Mobile indicates that the two-year phone upgrade cycle is, for many of us, a thing of the past. Most people are now holding onto their phones for at least three years, the survey revealed.

Of the 3,640 people Ting surveyed last month, 47 percent said they had their last phone for three to five years before upgrading, and another eight percent waited more than five years. Thirty percent upgraded at the two-year mark, and 15 percent traded up after just one year or less.

"After so many years of people being pressured into upgrading to a new phone when their old phone was perfectly functional, it's encouraging to see that so many of our survey respondents are hanging on to their devices for longer," Ting Mobile Content Director Andrew Moore-Crispin said in a statement. "People are more conscious about things like price and basic phone functionality. They don't care so much about having the latest, coolest tech—something that might not be great news for the big manufacturers this year."

Just 10 percent of survey respondents said they last upgraded their phone because they had to have a hot new model. On the contrary, 32 percent said they upgraded because their previous phone wasn't running as well as it had before, and 23 percent did so because their phone was broken, damaged, or lost.
