How long should you keep a phone?

Nokia 7.1 phone

New phone models arrive all the time. The phone product lines get an annual refresh.

Apple holds its annual iPhone launches all at once. In recent years this has always happened three or four months before Christmas.

Top Android phone makers like Samsung, Huawei and Nokia have more than one product lines. Each line gets its own annual update. The phone makers tend to stagger their launches throughout the year.

Add in the smaller brands and yes, we see a dozen notable phone launches each year.

Goodbye two year phone refresh cycle

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

Carriers agree. Their phone plans are two-year contracts. Remember carriers make money when you to buy new phones and roll over two-year contracts. While two-year contracts remain popular, they’re less common today than five years ago.

New Zealand’s Inland Revenue Department depreciates phones at 67 percent a year. That implies a life expectancy of under two years. Depreciation rates are similar in other countries.

We’re holding on to phones for longer

Most of us now hold onto phones for longer than two years. No-one forces us to operate on a fixed timetable.

There’s a noticeable difference between Apple and Android phones. Android phone users tend to keep their phones for a shorter time than iPhone users.

Apple’s sales figures reflect this. iPhone revenues peaked in 2015. Apple now focuses more on selling services to its customers to make up the revenue shortfall.

In 2016 Benedict Evans reported Android users keep phones for under two years. Back then, Apple iPhones stayed in use for more than two years. There are interesting theories about this in the comments on Evans’ post. This also explains why second-hand iPhones hold their value better than Android phones.

One reason people hold on to phones for longer is that upgrades are more incremental than in the past. A few years ago there would be dramatic changes from one year to the next. Now phone makers emphasise cameras and cosmetics.

It’s no accident that phone makers hold launch events that look like fashion shows. They want to create the impression that you need this year’s design. You almost never do.

Phone hardware can live for years

Phones can take a beating. Owners handle them many times each day. They get dropped, knocked, scratched and soaked.

Yet, there are few moving parts to seize up. (Avoid any phone that does include moving parts such as a pop-up camera.)

If you look after your phone 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 hold as little as half the charge they managed when they were new.

You can replace phone batteries, even those in sealed phones. It can be difficult, there are official repairers and a cottage industry exists.

Although it may look expensive, paying someone NZ$100 to replace a battery is cheaper than a new phone.

Screen life

Screens last three to ten years depending on the technology, build quality and your use. Often the screen backlighting goes first. Again, repairers can fix these problems.

There are times when a new phone model is compelling.

Sometimes moving from one year’s model to the next brings a must-have feature. Even so, you can expect to get at least two years from a device. They should last for three or more. Five years is no longer exceptional.

There are users who give their phones a pounding. If that’s you, or a family member, you have two choices. You could buy a more robust phone model. Or you could opt for a cheaper model that won’t break the bank when replacement time rolls around.

How long should you hold on to a phone?

There’s no simple answer to ‘how long should you hang on to a phone’. What works for one person doesn’t work for another. You should hold on for at least two years. Yet that’s unambitious.

For some people the best time to replace is when the battery life is not enough to get you through the working day. For others it’s when the operating system is no longer supported and there is a security risk. That’s roughly six years for Apple iPhone users.

Apple released iOS 13 in September 2019. It will support the iPhone SE but not the iPhone 5s, 6 or 6 Plus. Apple released the iPhone 5s in 2013, it is now out of support. If you think that is bad, spare a thought for Android users. Six years is more than double the official supported life of Android versions.

Update: If you love Android and worry about phone longevity, chose a Nokia phone. The company has a policy of keeping phone software up to date. It guarantees two years of updates. That’s far less than Apple, but that’s better than rival Android brands.

  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.

    1. 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.

    2. 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’… 😉

    1. 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.

  4. My answer would be: as long as possible 😀

    I kept my iPhone SE and 7 for 3 years now and want to get both of them going for two more years.

  5. And that allows me to skip one to two models. I have the P20 Pro and as long as I don’t need to sell a kidney I’ll probably get the P40 Pro sometime after release next year… I think that will be about 2 – 2.5 years

  6. I think that’s going to be widespread, although there will be a need to replace broken or clapped out kit. My guess is the replacements won’t be top of the line devices.

  7. These days by far the most important feature is software. This is why I refuse to buy Huawei or Oppo, despite their tantalising hardware. Samsung is doing really well with their OneUI skins however with only two major updates, it means you basically have to commit to buying the phone right at its release time if you want to get the most out of it, and with preorder deals I actually think it’s often worth it. Google’s Pixel line would be the best Android experience if it wasn’t for their lackluster hardware, and with 3-4 years of updates it’s very impressive.

    Your update at the end of the article is terrible advice. Two years of updates are very common. Buy a Samsung or a Google.
