A phone can look new and still be near the end of its software support. Before buying, check how much support remains for that exact model and how long you hope to keep it.
Look for security support as well as new features
Security updates fix known weaknesses. Operating system updates may add features or change how the phone works. A model can receive one kind of update without getting every new feature, so check both.
Count from the manufacturer’s start date
Buying a refurbished phone does not restart its support period. Google says Pixel 8 and later models receive seven years of operating system and security updates from their first availability in the US Google Store. Its Pixel update policy also lists the shorter periods for older models.
For Samsung, use the current security update list and the exact model’s product information. Update frequency and support vary by model. For iPhone, check Apple’s security releases for the devices covered by each update. A recent release is evidence of current support, not a promised future end date.
Use the years you plan to keep it
For example, a £180 phone kept for two years costs £90 a year before repairs and SIM costs. A £300 phone kept for four years costs £75 a year. These are simple examples, not predicted lifespans: battery condition, damage and support can change the result.
Do not pay for extra years you do not expect to use. Equally, a very low price may be less useful if important apps or security support are nearing their limits.
Check again when it arrives
Install available updates and check the phone’s software and security update details in Settings. If something does not match the listing, ask the seller promptly. Keep a backup of your data and review support again before passing the phone to someone else.
