CCHow To / Strong
A slow machine is often a battery, a full disk, or a missing patch, not a reason to buy a new one. The hard line CISA draws is end of security support. Repair is the right next step when the vendor still patches and the broken part is actually the bottleneck.
The argumentCISA's instruction for software that no longer receives security updates is to retire it, which is the one replacement trigger that is not a feeling. Everything else (runtime, heat, 'it feels slow') should be checked as a battery, a full drive, or a repairable part first. The FTC's repair work documents why that check is harder than it should be: parts, manuals, and pairing restrictions push people toward a new device before the old one is actually finished.
Is this laptop or phone actually done, or can I keep it going with a battery, storage cleanup, or repair?
If the vendor has stopped shipping security updates, CISA's guidance is to upgrade the OS or replace the product. Windows 10's free support ended October 14, 2025. A Pixel 5a or earlier is already off Google's update list. That is the hard line, not a new model year.
Apple designs iPhone 14 and earlier batteries to hold 80 percent of original capacity at 500 full charge cycles, and iPhone 15 and later at 1,000 cycles. Maximum capacity in Settings is the number to look at before you blame the whole phone. A battery replacement is a repair, not a new device.
A nearly full SSD makes a computer swap and stutter. Clearing space, or replacing a drive or battery the chassis still supports, is cheaper than a new machine when the OS is still patched.
The FTC's 2021 Nixing the Fix report found that limited parts, manuals, and diagnostic tools, plus designs that complicate repair, push people to replace products that still have useful life. Check parts availability (Apple's vintage and obsolete clocks are one example) before you assume repair is impossible.
A phone that dies by dinner, or a laptop that spins for ten seconds before a folder opens, feels finished. Often it is not. Lithium-ion batteries lose capacity as they chemically age. Apple publishes the design point in writing: iPhone 14 and earlier batteries are designed to retain 80 percent of original capacity at 500 complete charge cycles under ideal conditions, and iPhone 15 batteries at 1,000 cycles. When capacity falls far enough, the same document describes unexpected shutdowns and software that throttles the processor to keep the phone from crashing. Replacing the battery, Apple says, can restore performance. That is a repair. It is not a new phone. A Windows laptop with a swollen or tired cell is the same story with a different settings panel.
The replacement trigger that is not a feeling is security support. CISA's patching guidance says continued use of end-of-life software poses consequential risk, and it recommends retiring EOL products. The training module is more specific: if the developer no longer issues security updates, upgrade the OS or replace the product. Microsoft ended Windows 10 support on October 14, 2025. Google lists Pixel 5a and earlier as no longer receiving Android or security updates. Those machines still power on. They are, in CISA's terms, already in the replace column unless you have a short, named exception (Microsoft's paid Extended Security Updates through October 12, 2027 is one). A new laptop ad is not a named exception.
You are considering replacing a phone or laptop. Work the questions in order. The first 'replace' you hit is the one that matters. Do not start at the store.
Check Settings for a current patch date. For Windows 10, support ended October 14, 2025. For Pixel, Google publishes the window. For iPhone, an update offered in Settings is the signal; months without a patch is the other signal. CISA: retire EOL software.
On iPhone: Settings, Battery, Battery Health, Maximum Capacity. Apple describes performance management that kicks in after unexpected shutdowns on an aged battery. On laptops: cycle count or a vendor battery report, plus whether the machine only misbehaves unplugged.
A few gigabytes free on an SSD will make photo libraries, browsers, and OS updates crawl. On a laptop, too little RAM for the workload shows up as constant disk activity. Neither of those is 'the processor is old' until you have checked.
Screen, keyboard, port, hinge, battery. Apple vintage: last sold 5 to 7 years ago, parts maybe. Obsolete: last sold more than 7 years ago, Apple stops hardware service. The FTC's Nixing the Fix report is about the cases where parts and manuals were withheld even when the product was younger.
Battery health is the check people skip because the phone still reaches 100 percent on the charger. Maximum capacity is not that number. Apple defines it as the battery's capacity relative to when it was new. As the cell chemically ages, runtime shrinks, and the battery's ability to deliver peak power drops. In cold weather or at a low state of charge, that drop is worse. iOS will then manage performance to avoid an unexpected shutdown. The phone feels old. The cell is old. Apple's Battery Health screen will say when health is significantly degraded and point you at an authorized repair. Out of warranty, that repair costs money. It still costs less than a flagship, and it leaves you on a phone that may have years of software support left. A laptop with a 40-minute unplugged life is the same diagnosis with a screwdriver or a shop quote.
Storage and RAM are the other false 'replace' signals. Operating systems and browsers use free disk as working space. When a 256 GB drive is at 240 GB, updates stall, photos fail to import, and the machine swaps constantly. Deleting the installers you already ran, offloading the photo library to a disk or a cloud you actually pay for, and uninstalling three Electron apps will not make a 2018 laptop new. It will often make it usable again. RAM is similar, with a harder stop: many current thin laptops solder the memory. If the model can take a second stick or a larger SSD, that upgrade is a repair in slow motion. If it cannot, and you regularly hit memory pressure, you have a capability gap, which is a legitimate replace, not a moral failing of the old machine.
Windows 11 eligibility is the other hard hardware line, and it is documented. Microsoft's end-of-support page tells Windows 10 owners to check Settings, Windows Update, or the PC Health Check app, and to read the Windows 11 system requirements. A PC that fails that check cannot take the free OS upgrade. Microsoft's remaining paths are a new Windows 11 PC, or consumer Extended Security Updates through October 12, 2027. ESU is a dated bridge for a machine that still does the job. It is not a reason to skip the battery and storage checks on a PC that can move to Windows 11. If the PC qualifies, the 'replace' you were about to make may be an OS upgrade and a battery.
Data migration is the step that makes replacement survivable and repair less scary. Microsoft points at Windows Backup for files, photos, settings, apps, and credentials. Apple's Quick Start moves a phone; a Mac can use Migration Assistant or a Time Machine disk you have already tested. Do the copy, open three real files (a tax PDF, a photo from last year, a password manager vault), then wipe. A repair that involves a logic board should get the same copy first. The old device, once wiped, should leave the network. CISA's EOL advice is not only 'buy a new one.' It is 'stop running the unpatched one as if it were still in the household's trust boundary.'

Repair versus replace is a price comparison only after the first three questions are answered. If the OS is unsupported, repair does not restore patches. If the OS is supported and a $129 battery or a $200 screen puts five more years of updates in your pocket, repair wins. Compare the quote to remaining support years, not to the sticker on a new flagship. A $180 battery in a phone that still has three years of patches is a different purchase from a $180 battery in a phone Apple will stop patching next fall. The FTC's 2021 report to Congress, Nixing the Fix, is the document that explains why that comparison is often rigged. Manufacturers limit spare parts, withhold service manuals, and restrict diagnostic software. The report notes that control of spare parts makes it hard to replace consumable parts that are likely to need replacement during a product's useful life, such as mobile phone batteries, and that it may result in consumers replacing appliances and other products simply because they cannot obtain a spare part. The Commission's follow-on policy statement says those restrictions can raise repair costs, increase electronic waste, and lengthen wait times. If a shop tells you they cannot get the part, that may be a supply fact, and it may be the restriction the FTC described. A second shop, an independent who can still order, or the manufacturer's own battery program is worth one more call before you order a new laptop.
Apple's own service clocks are at least published. Owners may obtain service and parts for a minimum of five years from when Apple last distributed the product for sale, and up to seven years subject to parts availability. Vintage means last sold more than five and less than seven years ago. Obsolete means more than seven, after which Apple discontinues hardware service and providers cannot order parts. Mac laptops may still qualify for battery-only repair for up to ten years. Software support is a different clock. An obsolete iPhone can still boot. It will not get a genuine Apple battery through official channels. Plan the repair while the model is still on the vintage side of that line, not after.
When you do replace, the old device is a data problem before it is a recycling problem. Microsoft's Windows 10 end-of-support page points at Windows Backup for files, photos, settings, and credentials. Apple's Quick Start and a Mac-to-Mac transfer exist for the same reason. Do the copy, open three files on the new machine, then wipe the old one. An unpatched laptop left on the household Wi-Fi as a 'spare' is the EOL case CISA wants off the network. For phones, a trade-in that wipes on the counter is fine if you have already signed out of the Apple or Google account. For routers and other edge devices, CISA's 2026 directive to agencies is the adult version of the same idea: when the vendor stops patching a box that faces the internet, you remove it.
Heat and dust impersonate a dead computer. A laptop that throttles after twenty minutes, or a desktop whose fans scream, is often a blocked vent or dried thermal paste, not a CPU that has forgotten how to work. That is a cleaning or a shop hour, and it is worth doing before you price a replacement, especially if security updates are still arriving. It is not in CISA's EOL list because it is not a software-support problem. It is in this article because it is one of the ways a still-supported machine gets thrown out. Open the vents. If you are not comfortable inside the chassis, a repair shop can clean it for less than a new laptop. Then rerun the battery and storage checks. Only then is 'it still feels slow' a capability gap.
The honest replace, after all of that, is still common. A Windows 10 PC that cannot run Windows 11, a Pixel that has aged off Google's list, a laptop whose soldered 8 GB cannot run the software you are paid to use, a phone whose parts are obsolete and whose battery is at 72 percent: those are done. Buy the next one for the support window (Pixel's seven years is a real number you can plan around) and for a battery you can still have serviced. Do not buy it because a folder took three seconds to open on a disk that was full. Price the replacement against remaining support years, not against the holiday ads. A cheaper phone with two years of patches left is a worse buy than a used Pixel still inside Google's published window.
If they are not, you are in CISA's replace column. If they are, keep going.

Tens of gigabytes, not a handful of screenshots.
Apple vintage/obsolete, or the PC maker's spare-parts policy. The FTC's report is why a 'we can't get that' answer deserves a second shop.
Do not leave the old, unpatched machine on the network as a spare.
Not for that number. Apple's design language around 80 percent is about expected capacity after hundreds of cycles, and the Battery Health screen has a separate message when health is significantly degraded. If runtime is still acceptable and patches are still arriving, keep the phone. If runtime is not acceptable, ask for a battery, not a replacement device.
Because Microsoft has stopped shipping security updates for it as of October 14, 2025, unless you pay for ESU. CISA's EOL advice is about attackers using known holes, not about whether Word still opens. If the PC can move to Windows 11, that is the upgrade. If it cannot, ESU is a dated bridge, then a new PC.
It may be, if the model is obsolete and parts are gone. It may also be the parts-pairing and parts-control problem the FTC documented in Nixing the Fix. Try the manufacturer's own battery or screen program, and an independent shop, before you treat 'no' as a physics result.
Retire devices the vendor has stopped patching. For the rest, read battery health, free storage, and price a repair against a still-supported replacement. A new model year is not a diagnosis.

CISA's advice is to turn automatic updates on and to stop using software that no longer gets patches. The part that becomes a weekend project is everything that does not auto-update: routers, printers, and the one laptop still on an OS the vendor has already retired.
