Manufacturers are very good at convincing customers that two-year-old hardware is obsolete. The marketing cycle, the carrier financing structure, and the constant drip of incremental feature releases conspire to make holding a device for four or five years feel almost embarrassing. The actual hardware tells a different story: most consumer technology built since roughly 2018 is more capable than its average user requires, and the upgrade cadence the industry sells is dramatically faster than the cadence that serves the buyer.
Phones plateaued years ago for normal users
The iPhone X came out in 2017. Its successor’s processors, cameras, and screens have improved every year, but the rate of improvement has decelerated sharply. Apple’s own software support extends back six to seven years now — iOS 18 ran on the iPhone XS, a 2018 device. Android flagships from 2020 onward generally remain capable for five-plus years for the typical use pattern of email, messaging, navigation, photos, and streaming. The features driving each year’s marketing — incremental camera improvements, slightly faster chips, periodic redesigns — are real but rarely transformative. A user upgrading every two years on a financed plan typically pays $1,000 to $1,500 more over a decade than a user replacing every four to five years, and gets an experience that’s only marginally different at any given moment.
Laptop upgrade pressure is mostly software-induced
Laptops from the past five to seven years remain entirely usable for the workloads that describe most knowledge work. The pressure to upgrade comes from three sources: battery degradation (genuinely real, often fixable for $80 to $200), software bloat (operating system and app updates that demand more resources than the original release), and gradual user adaptation to the slower experience. Apple’s M-series silicon transition in 2020 was a genuine generational leap that made some upgrades worthwhile; outside that specific moment, most users replacing a 2019 ThinkPad or MacBook in 2024 didn’t need to. SSD upgrades and battery replacements extend the useful life of older machines by years and cost a small fraction of a new device.
TVs, appliances, and the upgrade theater
Televisions improve in spec sheet ways every year — refresh rates, peak brightness, panel technology — that typical viewers cannot perceive in normal viewing conditions. The 4K to 8K transition has stalled because there is essentially no 8K content for consumers, and even most “4K” streaming is heavily compressed. Refrigerators, washers, and dryers have actually become less reliable on average since 2010, with median lifespan dropping in Consumer Reports data; “upgrading” a working appliance is often a downgrade in durability. The pattern across product categories is consistent: the device you have is usually fine, and the urge to replace it is manufactured.
The takeaway
Default to keeping hardware until something genuinely breaks the workflow — battery life that won’t make it through a workday, software no longer supported, a feature you actually need that’s only in newer models. Define those criteria before you walk into the store. The financial difference between upgrading on the marketing cycle and upgrading on the necessity cycle is, over a lifetime, large enough to matter.
