A dated answer, backed by sources
StillWorthIt turns scattered support and repair information into a clear verdict for an exact product model.
The current catalog
Every verdict has a review date and links to the manufacturer evidence behind it.
The iPhone 11 remains compatible with iOS 27. Keep a working unit if its battery and storage still meet your needs. A used purchase only makes sense after checking battery health, repair history, activation lock, and local price.
The iPhone 12 remains on Apple's iOS 27 compatibility list. Keep it when performance and battery life are adequate. For a used unit, verify battery health, display and camera operation, repair history, activation lock, and the total cost after any battery service.
The iPhone 13 remains compatible with iOS 27 and is the strongest all-round used-buy candidate in this initial set. Unit condition still controls the decision: inspect battery health, repair history, activation lock, cameras, display, ports, and local total cost.
The original Galaxy S21 is absent from Samsung's current monthly and quarterly security-update lists, while the later S21 FE remains listed. Treat regular security support for the original S21 as ended unless Samsung or your carrier shows otherwise for the exact variant. Repair may still be economical for short-term or secondary use.
Google states that Pixel 6 receives five years of OS and security updates from first availability. With the model first sold in October 2021, that window is near its end in late 2026. Keep it briefly if updated and reliable, but do not choose it now for long-term security support.
The iPhone 14 remains compatible with iOS 27 and has a stronger support runway than the older models in this set. Keep a sound unit. A used purchase still requires checks for battery health, activation lock, repair history, cameras, display, and total local cost.
Apple still lists the second-generation iPhone SE for iOS 27, but its age and small battery make unit condition decisive. Keep it for light use when the battery is sound. A used purchase only works at a low price after a full battery and repair-history check.
Samsung currently lists the Galaxy S21 FE 5G for quarterly security updates. That supports continued use, but the reduced update cadence and model age make it a short-horizon used purchase. Confirm the exact regional variant and latest installed patch.
Samsung currently lists the Galaxy S22 series for quarterly security updates. Keep an updated, reliable unit, but treat the lower update cadence as a reason to plan ahead. Used value depends on patch level, battery, condition, exact variant, and price.
Google gives Pixel 7 five years of OS and security updates from first US availability. It remains in that window, but a 2026 used buyer has a limited support horizon. Keep a reliable unit; buy only when the price reflects the remaining runway.
Use the verdict well
Start with software support and safety notices. Then compare the actual unit's battery, repair history, condition, and local repair cost. The same model can be worth keeping and still be a poor used purchase.
