The holidays might be over, but the festive season brings a wave of new toys, from smartphones to game consoles, digital cameras to HDTVs. It’s the electronic antidote to the post-holiday blues.

But just how long will all of these new gadgets last?

For certain household items, shoppers will wait until the device stops working, which is typical for appliances like washing machines, dryers, and dishwashers — a period that can exceed ten years. However, for other products, customers often choose to buy a new model long before the old one fails.

To get a sense of consumer mindsets across product lines, the Consumer Electronics Association surveyed 1,013 adults on electronics life expectancy. At SpecOut, we charted the results, then did a bit of our own data-driven speculation. The chart below shows consumers’ average expectations for seven popular products.

The TV: New Features, Skeptical Consumers

With technology getting cheaper every year, television makers have tried to invent new reasons to buy. Five years ago, they focused on three dimensions. Today, they’re pushing 4K resolution — TVs with double the horizontal pixels of an HDTV.

None of it seems to be working. Consumers still think a new TV will last over seven years, the longest lifespan of any product on this list. They’re right to be skeptical: 3D TVs never really clicked with couch potatoes. Today, most 4K sets remain over-the-top, particularly when the majority of TV programming can’t even render the content at such a high resolution. It also doesn’t help that the newest TV technology tends to carry a $500 to $1,000 premium.

Digital Cameras: Pricier Models, Fewer Purchases

As smartphone cameras have improved, digital camera makers have been forced to make a decision: beat the smartphone on price, or retreat to the high end, offering more features and better image quality at a premium price point?

The data says they’ve chosen quality, with the average camera cost rising steadily for half a decade, among both point-and-shoots and DSLRs.

Unfortunately for Canon and Nikon, that also makes consumers reluctant to buy frequently. As it stands, customers believe digital cameras will last 6.5 years. And by 2022, the smartphone will likely swallow up even more of the market.

Blu-ray Players: Rest in Peace

It’s been 10 years since the Blu-ray player launched, just short of two product life cycles. Some early adopters might have bagged two players by now, but the product looks likely to wind up a one-and-done for most American households. Sure, families will replace the device after about six years, but they’ll do so with Netflix, HBO Go and Apple TV, not more discs and Blu-ray features. And even if they don’t, they can always just use their PS4s or Xbox Ones.

Game Consoles: Just How Manufacturers Like It

Like the digital camera market, game consoles have had to weather the smartphone onslaught, as 99¢ mobile games have threatened to replace $60 console titles. And yet, the game console industry remains strong, with Microsoft and Sony consistently selling between 10 and 15 million consoles per year since 2008.

Unlike TV makers, console manufacturers seem to have figured out the economics of the industry. When a console is brand new, they sell the machine at a loss. Then, they recoup the money through pricey software sales and increasingly cheaper technology over the course of six years. The longer the product life cycle, the better for the console maker.

It’s the sort of lifespan that can make a PC gamer’s head spin (they can’t believe people would spend hundreds for six-year-old technology), but it sure makes for good business. Console makers appear to be winning the messaging war with consumers, who peg a console’s life cycle at 5.7 years.

Laptops: Better Performance, But Less Demand

For laptops, lifespan heavily depends upon daily use. If you use the same machine all day at work and sometimes into the night, you’ll be lucky to get three good years out of the product. Conversely, if you save your laptop for occasional trips or light evening use, you could potentially squeeze out a full decade.

On average, consumer opinion splits the difference, pegging a laptop’s lifespan at 5.5 years. On the one hand, smartphones and tablets have likely lengthened the product cycle, as consumers spend more time on handheld devices — and less time wearing down their laptops. On the other hand, laptop specs have significantly improved over the last five years, which makes a 2011 laptop far inferior to a recent release. In the end, it’s a wash.

Tablets: Style, But Little Substance

With a life expectancy of just 5.1 years, tablets earn the second-shortest lifespan on this list.

Still, 5.1 years is a long life for a mobile device, especially in a world of two-year smartphone contracts and major yearly product releases. Indeed, many tablet makers complain that consumers don’t buy tablets often enough.

Part of the issue might be the slow pace of annual performance upgrades. While tech manufacturers tend to cram their flagship smartphones with the most advanced technology available, tablet improvements have been more modest. Consider that tablet battery life, RAM and screen size have held remarkably consistent for five years. If manufacturers aren’t making notable improvements, how can they expect customers to upgrade?

Smartphones: The King of Consumer Electronics

At last we arrive at smartphones, which consumers believe will last 4.6 years, on average — the shortest lifespan of any product in the survey. Given that Americans spend nearly five hours per day using their phones, it’s a miracle the devices even survive that long.

Still, a 4.6-year life cycle is perfect for smartphone makers and third-party dealers. They like to buy back smartphones after two years, then resell the refurbished unit to a second customer. It’s just about the only industry in the world where customers are willing to pay more than $500 every two years.

You can bet TV, tablet and digital camera executives would love to play by the same rules. For now, however, the smartphone is king.
