An iPhone lasts six to eight years on average. Software is rarely the issue: the 2019 iPhone 11 still gets iOS 27 in 2026. What usually runs out first is the battery, and that can be replaced. Here is how long Apple provides updates, how long a battery lasts and when a different iPhone makes sense.
The short answer
- Software: Apple usually gives iPhones six to eight years of new iOS versions, followed by security updates for a while.
- Battery: after about 500 charge cycles (iPhone 15 and later: about 1,000) battery health drops towards 80%.
- Buying refurbished? Choose a model that gets iOS 27, so you have years of updates ahead.
How long does an iPhone get updates?
| Model | Released | iOS versions | Support |
|---|---|---|---|
| iPhone 8 and X | 2017 | iOS 11 to iOS 16 | 6 years of new iOS versions, then security updates until May 2026 |
| iPhone XS and XR | 2018 | iOS 12 to iOS 18 | 7 years |
| iPhone 11 | 2019 | iOS 13 to iOS 27 | 8 years and still supported |
| iPhone 12 and later | 2020+ | iOS 14 to iOS 27 | Still supported |
Since June 2025, manufacturers in the EU must also provide software updates for at least five years after a phone is taken off the market. To find out which iPhone you have, see Which iPhone do I have?
How long does the battery last?
The battery wears fastest. According to Apple, an iPhone battery keeps about 80% capacity after roughly 500 full charge cycles; iPhone 15 and later after about 1,000. With daily charging, older models reach about 80% after one and a half to two years. That doesn't mean your iPhone is finished: with a new battery it lasts for years. See iPhone battery health.
Make your iPhone last longer
- Install iOS updates; they contain security fixes.
- Use a case and screen protector.
- Turn on Optimised Battery Charging and avoid heat.
- Keep at least a few GB of storage free.
When does a different iPhone make sense?
- Your iPhone no longer gets security updates (like the iPhone 8 and X since May 2026).
- Apps you need no longer work on your iOS version.
- You want Apple Intelligence, which needs an iPhone 15 Pro, 16 or 17.
A refurbished iPhone from iUsed gets iOS 27, has a battery of at least 80% and a 3-year warranty.
