When Should You Upgrade Your Apple Devices?
The simple answer to “When should you upgrade?” is when your device no longer does what you need, or when you want something new. But that’s not helpful if you’re trying to make an informed decision—is there a sweet spot when it makes more sense to upgrade rather than squeeze another year out of your current device?
The answer is yes, and the specifics depend on the type of device, whether it’s used for work or personal tasks, and how central it is to your daily life. Here’s our advice, including recommended timeframes and the warning signs that suggest it’s time to upgrade.
Mac Upgrade Cycles
Macs boast impressive longevity, particularly those with Apple silicon. With proper care, a Mac can easily remain productive for 5–7 years, though business environments typically benefit from shorter replacement cycles. Apple provides security updates for the current macOS version and the two previous versions, giving you roughly 2 years of security updates after a Mac loses support for the newest macOS.
For business use, we recommend a 3–5 year replacement cycle. Research shows that hardware problems increase after this point, performance lags compared to current machines, and resale value drops. The loss of productivity from slow performance and downtime outweighs the cost of a new Mac. If you don’t already have one, make an inventory of all your Macs, including purchase dates, and use it to create a replacement schedule. Also consider shuffling Macs around—an employee doing video work might get annual upgrades to the most powerful Mac available, with their old machines handed down to others.
Consider upgrading a Mac when:
- It no longer receives security updates: Once security updates stop, the Mac becomes increasingly vulnerable to attack. Intel-based Macs are coming due here—macOS 26 Tahoe is the last version to support them, so security updates will end in 2028.
- Its battery no longer holds a reasonable charge: For MacBooks, battery degradation often drives upgrade decisions. Although Apple will replace the battery for $149–$249, it’s usually more effective to upgrade the entire MacBook.
- Performance hampers productivity: If apps launch slowly, you see the spinning beach ball regularly, or you find yourself waiting on the computer throughout the day, a newer Mac will increase your productivity.
- Storage is perpetually low: Running low on storage can reduce performance, block software updates, and force distracting cleanups. If you can’t offload files to external or cloud storage, consider upgrading to a Mac with more capacity.
For personal Macs, you can extend the replacement cycle to 5–7 years or even more as long as the Mac meets your needs and continues to receive security updates.
iPhone Upgrade Cycles
Despite the rough treatment they often receive, iPhones are remarkably durable, with many users keeping them for 4–5 years without significant issues. Apple typically supports iPhones with software updates for 5–6 years after release, making them the longest-supported smartphones on the market.
For business use, we recommend a 3-year replacement cycle. That ensures employees always have devices that support the latest security features and iOS capabilities, including Apple Intelligence, which requires an iPhone 15 Pro or later. A 3-year cycle also means better resale or trade-in value—iPhones depreciate more gracefully than most technology, but that advantage diminishes after the third year.
For personal use, replace your iPhone when:
- Battery health drops below 80%: Check in Settings > Battery > Battery Health. Below 80%, you’ll notice significant performance throttling and shortened battery life. Replacing the battery for $69–$119 through Apple—it’s best to avoid third-party replacements—can extend a phone’s life by another 2–3 years if everything else works well.
- It no longer receives iOS updates: Once security updates stop, it’s worth considering replacing it. Typically, Apple releases updates only for the current version of iOS, but this year, it has been providing iOS 18 security fixes for the iPhone XR and XS models, and even released a few critical security updates as far back as iOS 15 and iOS 16.
- Storage is consistently full: If you’ve enabled Optimize iPhone Storage (Settings > Apps > Photos), turned on Offload Unused Apps (Settings > Apps > App Store), and are still frequently managing storage to make room for new photos, videos, and iOS updates, it’s time to upgrade.
- The camera no longer meets your needs: Camera improvements have been substantial year over year. If photography matters to you and your iPhone is more than 3–4 years old, a new model will deliver noticeably better results.
iPad Upgrade Cycles
iPads have a longer practical lifespan than Macs or iPhones. It’s not unusual for an iPad to remain useful for 6–7 years, particularly for basic tasks like Web browsing, email, video streaming, and reading.
The upgrade trigger for iPads is usually one of three things:
- Battery life has declined noticeably: iPads from 2024 and later (starting with the M4 iPad Pro, M2 iPad Air, A17 Pro iPad mini, and A16 iPad) display battery health in Settings > Battery > Battery Health. For older iPads, you can check battery health using Mac apps like coconutBattery or iMazing. If capacity has dropped below 80% or the iPad no longer holds a charge through a typical session, it’s time to upgrade. Apple offers iPad battery replacement for $99–$199, but upgrading may make more financial sense.
- Performance becomes frustrating: iPads used for demanding tasks like video editing, illustration, or running multiple apps will show their age faster than those used for content consumption.
- Software support ends: Apple supports iPads for roughly 5–6 years. Once updates stop, security risks increase.
For business use with demanding workflows, a 3–5 year cycle makes sense. For general business use (email, documents, presentations), an older iPad will probably work well enough for 5–6 years. Personal iPads used primarily for media consumption can last until software support ends.
Apple Watch Upgrade Cycles
Apple Watch upgrade cycles depend heavily on how you use the device. Battery degradation is the primary limiting factor—most users report noticeable battery decline after 3–4 years of daily use.
Consider upgrading your Apple Watch when:
- The battery no longer lasts a full day: Check your battery’s condition on the watch in Settings > Battery > Battery Health. If maximum capacity has dropped below 80% or you’re charging midday to make it to bedtime, the battery has degraded significantly. Battery replacements cost $79–$99 from Apple, but given the watch’s age at that point, upgrading usually makes more sense.
- Performance feels sluggish: Newer watchOS versions can bog down older hardware. If apps take a long time to launch, Siri responds slowly, or the interface stutters, a newer watch will feel dramatically faster.
- New health features matter to you: Apple regularly adds meaningful health capabilities. Recent additions like sleep apnea detection may be worth upgrading for.
For most users, a 4–5 year upgrade cycle is reasonable. If you rely on your Apple Watch for health monitoring or use it heavily for workouts, you might prefer a 3–4 year cycle to ensure accurate sensors and reliable battery life.
Other Apple Devices
What about the other items in Apple’s product lineup?
- Apple TV: Most people can keep an Apple TV for 5–7 years without issue. The only real reason to replace an Apple TV HD or 4K is if performance has become sluggish or you want specific new features like Thread support for smart home devices.
- AirPods: Battery degradation is unavoidable in devices this small. Most users find that AirPods need replacement after 2–3 years as battery life diminishes. Battery replacement costs $49–$79 from Apple, but the economics and new features usually favor replacement.
- HomePod: HomePods have long useful lives with little reason to upgrade. Replace a HomePod only if it stops working or if you want features exclusive to newer models, like sound recognition for smoke alarms.
- AirTags: You can replace the CR2032 batteries in AirTags, so the main reason to replace an AirTag is if it’s lost or physically damaged. Apple released a second-generation AirTag with improved range, but if your current AirTags are working fine, there’s no compelling reason to upgrade.
- Vision Pro: There’s now an M5-based Vision Pro, but it’s a modest update—if you have the original M2-based model, there’s no reason to upgrade. If you have a Vision Pro, enjoy it—you’re still pretty much on the bleeding edge.

How AI Vulnerability Detection Changes Software Security
The latest generation of AI models has fundamentally changed how quickly security vulnerabilities can be found in software, for both defenders and attackers. Understanding what’s happening helps explain why we keep emphasizing the importance of keeping your devices updated.
In April 2026, AI company Anthropic announced Mythos Preview, an AI model with unprecedented capabilities for finding security flaws in software. Unlike previous AI-assisted security tools that often produced false positives and created more work for human evaluators, Mythos proved that it can discover true vulnerabilities that have evaded detection for decades—including a 27-year-old bug in OpenBSD, an operating system famous for its security.
Alongside Mythos, Anthropic launched Project Glasswing, a collaborative effort with approximately 50 partners—including Apple, Microsoft, Google, Amazon, and numerous financial institutions—to identify and fix vulnerabilities in critical software before similar AI-powered capabilities fall into the hands of malicious actors. As Firefox engineers said when reporting on their use of Mythos, “The current moment is a perilous one, but also full of opportunity. Let’s work together to secure the internet.”
Why This Matters
The security implications are significant. Within a month of Project Glasswing’s launch, Anthropic reported that partners collectively found more than 10,000 high- or critical-severity vulnerabilities in their software. Several partners reported that their bug-finding rate increased by more than tenfold.
Firefox developer Mozilla published compelling evidence of Mythos’s capabilities, noting that it identified and fixed 271 vulnerabilities in Firefox 150—over 10 times as many as they found in Firefox 148 with the previous-generation Claude Opus 4.6. Of those 271 bugs, 180 were rated high-severity, meaning they could be exploited through normal user behavior, such as browsing a Web page.
Mozilla’s results are remarkable for both their volume and their quality. Firefox engineers reported finding bugs that had remained undiscovered through many years of traditional security testing.
How Apple Fits In
Apple is a founding partner in Project Glasswing, yet another signal that the company takes security seriously. Apple’s vertical integration—controlling everything from chip design to the operating system to the App Store—gives it a structural advantage in secure design. For instance, Apple’s newest M5 Mac chips and A19 iPhone and iPad chips include Memory Integrity Enforcement (MIE), a hardware-level protection designed specifically to stop memory corruption exploits.
However, even these cutting-edge protections aren’t invulnerable. Security researchers at Calif.io demonstrated the first public macOS kernel memory corruption exploit on M5 silicon in May 2026. Working with Mythos Preview, they built a working privilege escalation exploit in just five days—targeting hardware protections that Apple spent five years developing.
An Arms Race Against Time
The uncomfortable reality is that while Anthropic currently controls access to Mythos, equivalent capabilities will inevitably become more widely available. OpenAI and Google probably already have similarly capable models in development, as do other AI model developers, some of whom may be accessible to or even beholden to hostile entities.
The security dynamics differ depending on whether we’re talking about existing software or new code that hasn’t shipped yet. For new code, defenders have a clear advantage—they can scan for vulnerabilities before release and catch bugs that would never have been found manually.
For existing software already running on billions of devices, the picture is darker. Attackers only need to find one exploitable bug to get in; defenders need to find and fix all of them. Worse, attackers don’t have to test their code to avoid breaking features, schedule a release, or get approval from other departments—they can exploit a vulnerability the moment they find it. As the Zero Day Clock site shows, the window between a vulnerability being discovered and being exploited has dropped precipitously—what once took months now happens in days and is expected to happen in minutes in a year or two.
This transition period—while AI rapidly discovers vulnerabilities in existing code that takes time to patch—is where we’re most at risk. The Zero Day Clock site features a call to action offering 10 suggestions for how the industry—and society—should rethink cybersecurity to stave off this threat.
Keep Installing Updates
For most users, the best defense against AI-powered exploits is nothing new—keep your devices updated—but it’s more important than ever. The fixes in Apple’s updates increasingly include patches for AI-discovered vulnerabilities. Practically speaking, you should:
- Enable automatic updates: Don’t allow yourself to forget to install updates. On iPhones and iPads, go to Settings > General > Software Update > Automatic Updates. On Macs, go to System Settings > General > Software Update, click the ⓘ button, and turn on all the switches. (If you’re working in an organization with an update policy, check with IT first.)
- Consider security in hardware upgrades: Although the main reason to upgrade hardware should be functional, keep in mind that a newer device will likely be more secure thanks to improved hardware protections.
- Replace unsupported devices: Hardware that no longer receives security updates is increasingly risky. This applies not just to your Apple devices but to every piece of gear that can be updated, including network hardware, printers, and smart home devices like cameras and doorbells.
In the long run, the emergence of AI-powered security tools favors defenders—developers will be able to catch many more bugs before shipping. For the near future, however, it’s essential that we keep our devices running the latest and most secure software.
