Some individuals improve to a brand new iPhone yearly, to get the most recent cameras or different options. However when you’re like most individuals, you retain your telephone for a number of years earlier than upgrading to a more recent mannequin. Maybe you primarily use your iPhone for the fundamentals, or really feel that so long as it isn’t damaged and the battery nonetheless holds a cost, there’s no actual purpose to improve. (The truth is, Apple will even substitute the battery for you at an inexpensive value, if yours has misplaced an excessive amount of of its capability.)

Nevertheless, you won’t bear in mind that there’s an actual hazard in utilizing an iPhone for too lengthy. Particularly, if an iPhone can now not run the most recent model of Apple’s iOS working system, it would miss out on a variety of essential safety updates. Vulnerabilities that stay unpatched can put you in danger.

On this article, we’ll clarify in better element why utilizing an outdated iPhone could be harmful, and which iPhone fashions are secure to purchase in 2023. (See additionally our article about when old Macs become unsafe to use.)

The chance of not getting safety updates: zero-day and zero-click exploits

Apple commonly points safety updates for all its platforms, and a few of these updates patch “zero-day vulnerabilities,” that are severe vulnerabilities which can be being actively exploited within the wild. Which means they aren’t merely theoretical vulnerabilities; any system that doesn’t get up to date is vulnerable to turning into compromised (hacked) by menace actors. Most customers don’t assume a lot about this, however there’s a actual hazard to not getting safety updates on your iPhone.

Zero-click vulnerabilities

Essentially the most severe of those are what are known as “zero-click” vulnerabilities. The sort of vulnerability exploits weaknesses within the working system to compromise gadgets—with out the person doing something in any respect. You don’t need to get tricked into launching an app or tapping on a hyperlink to a web site. Many of those exploits make the most of vulnerabilities that happen when, for instance, a preview of a webpage or photograph is displayed within the Messages or Mail apps.

Zero-click exploits may even infect your system when it’s fully locked, simply sitting there in your Lock Display. It’s well-known that the NSO Group’s Pegasus adware has used zero-click exploits in its arsenal of assaults, which have focused the iPhones of politicians, journalists, and activists. Most of those assaults try to compromise gadgets belonging to particular individuals with the intention to acquire intelligence. (See our story archives about Pegasus and zero-click exploits.)

Most common customers don’t essentially have to fret about Pegasus or related nation-state adware, per se. Nevertheless, ultimately the small print concerning the vulnerabilities utilized by Pegasus and different adware will come to gentle. (Notably, Apple offers some particulars about a lot of the vulnerabilities it patches. Furthermore, savvy specialists are in a position to reverse-engineer Apple’s patches to see precisely how a vulnerability was fastened—and the best way to exploit it on unpatched gadgets.) In different phrases, right now’s nation-state attacker’s vulnerability may develop into a part of tomorrow’s on a regular basis cybercriminal’s arsenal. And at that time, in case your iPhone or different Apple gadgets will not be up-to-date, then you might be in danger from extra widespread assaults.

WebKit vulnerabilities have an effect on all iOS browsers

Some vulnerabilities that Apple patches in its safety updates contain WebKit, the rendering engine utilized by the Safari Internet browser. The truth is, as of iOS 16, all third-party browsers on iOS and iPadOS use WebKit; Apple’s App Retailer insurance policies prohibit browsers like Firefox and Chrome from bringing their very own engines. (This may occasionally change starting with iOS 17, if Apple is forced to allow third-party app stores.)

Not having a completely up-to-date iOS model implies that your iPhone could possibly be compromised by merely looking to a hacked or malicious web site, and even if you view a malicious electronic mail with embedded wealthy Internet content material.

Apple’s patching coverage offers a false sense of safety

Apple commonly points safety updates for the present working programs of all its gadgets. They occasionally issue security updates for the previous versions of their operating systems, but it surely’s essential to bear in mind that these updates don’t at all times patch all vulnerabilities. (In some instances, some vulnerabilities patched in right now’s working system won’t have existed in final yr’s working system, however in different instances, Apple merely chooses to not back-port a patch.)

Persevering with to make use of the earlier working system model any Apple system on could be dangerous. Working an Apple system on an working system older than the earlier one is much more harmful, as a result of Apple has, in lots of instances, nearly fully (or fully) stopped issuing updates.

Sadly, Apple doesn’t make this clear to customers. If you happen to’re nonetheless utilizing an iPhone 7 right now, for instance, your system can’t run iOS 16—however you’re nonetheless getting safety updates pushed to your system for iOS 15. Until you learn The Mac Safety Weblog, you’re most likely blissfully conscious that iOS 15 isn’t absolutely patched, which implies it’s a lot much less secure to make use of than iOS 16. As only one latest instance, iOS 16 recently got Rapid Security Response updates for two actively exploited vulnerabilities, weeks earlier than iOS 15 obtained those self same vulnerabilities patched. After which when iOS 15 ultimately obtained these patches, iOS 15 got less than half as many security fixes as iOS 16’s corresponding update.

Put extra bluntly, Apple offers a false sense of safety by offering an incomplete set of patches to the “present minus one” OS, leaving customers weak however considering they’re protected. The identical isn’t just true for iOS 15, but additionally for iPadOS 15 and macOS Monterey as effectively. We’ve each purpose to count on that the identical will probably be true when future working programs come out that substitute iOS 16, iPadOS 16, and macOS Ventura; the “one model outdated” older working programs may nonetheless get patches, however will probably be considerably much less secure to make use of, and considerably extra weak to exploitation.

When do you have to improve your iPhone?

Many individuals assume that an iPhone, if it hasn’t been broken, ought to final for about three years. The age at which individuals have traded in iPhones has elevated in recent times, and now the average trade-in age is nearly three and a half years. However this masks the truth that many individuals don’t commerce in outdated telephones; they could maintain utilizing them for a few years, or cross them on to mates or members of the family. And do not forget that that’s simply the typical; whereas some individuals improve yearly, others wait 5, six, or seven years or longer earlier than shopping for a brand new iPhone.

With the intention to get the utmost worth out of an iPhone buy, it makes essentially the most sense to purchase new flagship fashions when they’re first launched, often within the fall of every yr. It will assist make sure that you get as a few years as doable out of your buy (as we are going to proceed to discover additional on this article). The principle factor to know is that if you purchase a brand-new mannequin, you possibly can relaxation assured that it’s going to get the utmost variety of years of main new iOS releases—and meaning the utmost variety of years of safety updates, too.

Which gadgets can run the most recent model of iOS?

For a few years, Apple ensured that outdated gadgets have been in a position to run the most recent model of iOS. You would have purchased a brand new iPhone in late 2015 that was nonetheless getting safety updates seven years later. Till iOS 16, which was launched in late 2023, you may nonetheless run the most recent model of iOS on an iPhone as outdated because the iPhone 6S. The truth is, the iPhone 6S had been the cutoff for gadgets supporting the most recent model of iOS since iOS 13 (see the chart under).

However Apple is might not at all times be so beneficiant; the corporate doesn’t have any revealed coverage concerning what number of years a given iPhone mannequin will proceed to get main new iOS variations. Additionally, understand that many iPhone customers don’t purchase instantly after a brand new mannequin comes out; some might wait till the early-fall gross sales in anticipation of the subsequent mannequin’s launch, simply to save lots of a bit of cash. This isn’t essentially a terrific thought from a safety perspective, if you wish to maximize the variety of years you possibly can safely get out of that system—however most individuals are fully unaware of this.

Based on Apple’s own statistics (as seen within the chart under), as of February 2023, 8% of all iPhones have been operating a model of iOS older than iOS 15—which implies their working system is greater than two years outdated. Many of those could also be gadgets older than the iPhone 6S, which was in a position to run iOS 15, however some may additionally be gadgets whose house owners have merely not upgraded iOS, for quite a lot of causes.

As an apart, even when we deal with simply the iPhone fashions launched previously 4 years—all of that are iOS 16 suitable—15% of them have been nonetheless operating iOS 15, and a further 4% have been operating one thing older than that. On the floor, that implies that practically 1 in 5 latest iPhones are operating a really outdated, outdated, and insecure working system. (In fact, if we have been in a position to dig deeper into which particular variations of iOS customers have been operating, we’d possible see that even amongst iOS 16 customers, comparatively few are putting in each iOS replace rapidly and staying absolutely patched at any given time.)

iPhones now not supported by iOS 17

A number of telephones that had been iOS-upgradable for years now not obtain full safety updates as of the discharge of iOS 16 in September 2022. Solely the iPhone 8 and X or later can run iOS 16. And with iOS 17 to be launched in only a few months, Apple will probably be drooping the iPhone 8, iPhone X, and iPhone XS from the compatibility record.

To be honest, Apple doesn’t minimize off gadgets as quickly as some Android producers do; many Android telephones solely get three years of safety updates from the primary sale date for a given mannequin.

Assume twice earlier than shopping for an outdated mannequin, regardless of how good a “deal” it could appear

If you happen to’re eager about shopping for an outdated mannequin of iPhone, or a refurbished unit, beware that its secure lifespan is proscribed. The identical is true when you hand an iPhone right down to a member of the family; it’s essential to make sure that the mannequin in query will nonetheless get main iOS updates for so long as you intend to make use of it.

Apple at all times sells one or two older mannequin iPhones, nonetheless new in field, alongside the most recent mannequin. From Apple’s perspective, it is a good method to attain a lower-income or extra price-conscious viewers, by providing iPhones which can be cheaper than the latest model. For now, Apple remains to be promoting the iPhone 12 and iPhone 13, alongside the latest mannequin, the iPhone 14. Apple can be promoting the iPhone SE (third era), which is the least costly new mannequin. It’s fairly secure to purchase an iPhone 13, as it’s more likely to get safety updates for just a few extra years. Nevertheless, launched in late 2020, the iPhone 12 is already three years outdated. It’s very doable that, when you purchase one now, you could not get even three years of safety updates for it. The newest iPhone SE, launched in March 2022, possible nonetheless has no less than just a few years of help forward of it, and will outlast the iPhone 12 on the subject of main iOS upgrades. It’s most likely not a terrific thought to purchase an iPhone 12 at this level.

(See our iPhone buyers guide to choose which model is best for you.)

What about refurbished iPhones?

Apple additionally sells some refurbished iPhone items. As of right now, the oldest iPhone that’s at present listed on Apple’s web site is the iPhone 11 within the U.S. and UK shops (although on the time of this writing, there are none in inventory). Nothing means that this mannequin received’t run iOS 17, but it surely’s fully doable that, come iOS 18 in fall 2024, Apple might now not help this mannequin. In concept, which means you may doubtlessly purchase an iPhone 11, instantly from Apple, which will solely be secure to make use of for a bit longer than a yr earlier than it now not receives safety updates.

This isn’t as unhealthy as Apple selling the Apple Watch Series 3 new after it had stopped getting security updates; it was unconscionable to promote a tool that had already been minimize off. Apple even continued to promote the Apple Watch Collection 3 refurbished for eight months after its remaining safety replace.

Do you have to purchase a used, refurbished, or “new in field” older mannequin of iPhone, from a 3rd social gathering?

You should purchase used, refurbished, and even “new” older iPhone fashions from many sources: Amazon sells them, eBay sellers at all times have loads of inventory, and cell carriers’ shops might promote them as effectively. If you happen to store round, you’ll possible see iPhone 8 fashions, and even older. Chances are you’ll assume you’re getting a superb deal purchase shopping for an outdated iPhone at a brilliant low cost, however doing so might put you in danger. It might both have already been minimize off from the most recent main iOS model, or it could quickly lose that profit just a few months from now, or in a bit over a yr—and meaning you may be minimize off from some essential safety updates.

What concerning the iPhone SE?

The present mannequin of iPhone SE (third Gen) was launched a bit over a yr in the past as of this text’s publication date. It’s a reasonably secure assumption that, based mostly on Apple’s previous practices, this mannequin is more likely to get no less than 5 extra years of main iOS upgrades.

A model new third-generation SE from Apple begins at $429. If you happen to store round, you possibly can most likely discover one for $300 or much less. (The truth is, it’s usually thrown in without cost when activating new service or when including a brand new line.) Averaging out the one-time $300–429 over the system’s optimal-security lifespan of roughly 5 extra years, the iPhone SE (third Gen) would value you round $5–7 monthly till you’d want to think about upgrading to a more recent mannequin. At that time, you’d most likely have to spend roughly the identical amount of cash to purchase the most recent iPhone SE or equal funds mannequin.

All instructed, it may value you as little as $5 monthly, on common, to at all times have a completely supported iPhone mannequin able to operating the most recent main iOS model.

Key takeaways

Not everybody can afford to purchase a model new iPhone mannequin each one to a few years. Shopping for an older mannequin to save cash can actually be tempting. Nevertheless, it’s essential to bear in mind that when you purchase one that’s greater than a few years outdated, it could find yourself turning into unsafe earlier than you already know it. Even when you purchase it from Apple.

So when is the very best time to purchase? If you wish to get the utmost lifespan out of your iPhone buy, purchase new, as quickly as the brand new flagship mannequin comes out, which is often within the fall. If you wish to maintain utilizing an iPhone for as a few years as doable, keep away from shopping for fashions which can be greater than a yr outdated; these fashions will get minimize off from main iOS upgrades ahead of newer gadgets, which can make them unsafe to make use of in a a lot shorter timeframe.

If you happen to’re on a decent funds, take into account getting the most recent mannequin of iPhone SE.
