However, when it comes to iPhones, you can wait three to five years (maybe longer) with proper care. You now have a good idea of how long your iPhone should last. You can expect five to seven years of major iOS updates, plus potential security patches beyond that. Battery performance will decline over time, but as long as you have enough storage space and avoid physical damage to your device, it should last quite a while.
Thinking about the signs that it's time to upgrade your iPhone can help you estimate how long your next iPhone will last.
