iPhone 6 Plus ipad

Tempting new phones arrive every month. Phone makers upgrade their main models once a year. You could almost set your watch by Apple’s annual iPhone launch event. Samsung and other popular brands run to a similar schedule.

Phone makers expect you to hang on to a device for two years even if they refresh their model lines every year.

Carriers agree. Their phone plans are usually two-year contracts. Remember carriers make money when you to buy new phones and roll over two-year contracts.

New Zealand’s Inland Revenue Department depreciates phones at 67 percent a year. That implies a life expectancy of under two years.

No-one forces us to operate on a fixed timetable.

Hardware lives for years

Phone hardware can last for ten years or more. There are no moving parts to seize up.

If you don’t drop your phone too often and it doesn’t pick up too much moisture, the battery is the first part to wear out. Constant use and charging cycles mean they degrade over time. After about three to four years use they’ve had it.

You can replace most phone batteries, even those in sealed phones. The difference there is more work or the cost of paying someone to do the job.

Screens tend to die somewhere between three to ten years depending. Often it’s the backlighting that goes first.

Research from Benedict Evans says Android users keep phones for under two years. Apple iPhones stay in use for more than two years. There are interesting theories about this in the comments on Evans’ post. This may also explain why second-hand iPhones hold their value better than Android phones.

There are times when a new model is compelling. I have an eye condition which means at times I squint at a tiny screen. For me the jump from the iPhone 5 to the 6 Plus wasn’t an indulgence, it was necessary.

There are other examples of when the move from one year’s model to the next brings a must-have feature. Even so, you should expect to get at least two years from a device. They should last for three or more.

7 thoughts on “How long should you keep a phone?

  1. I think you’re underestimating how hard people treat their phones. For phones in cases I am sure most can last 3+ years but most phones I see people use have lots of dings and quite often broken screens.

    Even though there is no moving parts things can still get dislodged with movement and moisture entering the device (especially sweat which has salt that does a lot of damage to circuits).

    Another thing that seems to break often is the plugs for headphones and USB cables.

    • Yes, there’s a difference between how long a phone lasts before it fails and how long you should keep a phone. If it’s on its last legs then it needs replacing.

    • I’ve seen people do nasty stuff to phones via the microUSB plug – picking it up, swinging it around… There’s not a huge amount of solder between the plug and the circuit board it’s on and rework in that area is often hard. There’s an efficiency loss with inductive charging, but it’s connectorless.

  2. I’ve had my Samsung S3 for about 3 years I think. When I got it I thought, hm, plasticky, with crappy finish around the bezel and side buttons…IDEAL. Because a phone is a tool, not ‘bling’, so I didn’t want to have to ‘look out’ for it.
    Still goes just fine, looks like a pile of junk, and has an extended life battery fattening its profile because the first one crapped out.
    Only thing now that makes me want to replace it is the flash has stopped working, affecting my ability to take pics of the kids. Your Huawei P8 review has me interested, Bill, so I blame you.

  3. I have had my iPhone 4S since 2011 & it still works fine & runs the latest operating system. Which is why I bought Apple in the first place. When you shell out $1000 for something that is small enough to fit in your hand (I used to tell people it was my 3rd kidney) you want it to last a good while.

    After looking at some of the newer models I’m starting to think it should have an unfortunate ‘accident’… 😉

    • Any device you buy will carry on doing what it did at the time of purchase until it drops dead. Thanks to regular software updates it can actually get better until an update comes along that asks too much of the hardware.

      If you’ve had four years use then it has cost about $5 a week, not a bad deal. Is there anyone you can pass the old phone on to? That might be a better justification for an upgrade than dropping it.
