If you want an iPhone built for the AI era that will last for years both in terms of Apple Intelligence functionality and iOS updates, the entire lineup of the iPhone 17, iPhone 16, and the two Pro models of the iPhone 15, which are the iPhone 15 Pro and iPhone 15 Pro Max, are your best choices. Here’s the breakdown:
iPhone 15 Pro Max
The refurbished iPhone 15 Pro Max is the sweet spot for Apple Intelligence (on-device AI) preparedness, as well as the iOS update cycle. This model is expected to receive regular iOS updates until 2030 and continue to receive security patches for two more years, up to 2032.
With this iPhone, you get the software updates, the newest AI features, and the hardware that can handle and run these updates not slow down due to them.
iPhone 15 Pro
In terms of performance and longevity, the refurbished iPhone 15 Pro is the more affordable option with the same longevity, performance, and software update potential as the iPhone 15 Pro Max. You can call it the best AI-entry iPhone with the A17 Pro chip, the same as the Pro Max’s, and, with ProMotion, it uses its battery efficiently while keeping high refresh rates when necessary.
iPhone 16 Lineup (including baseline iPhone 16)
While we had to exclude the baseline iPhone 15 from our list for AI preparedness, as it doesn’t really have the RAM capacity for it, the baseline iPhone 16 comes with 8 GB of RAM, which is the minimum requirement for what we’re expecting future software updates to require, both iOS and third-party apps. One of the pluses of the iPhone 16 lineup is that all models have a dedicated camera control button for photography and content creation purposes.
iPhone 17 Lineup (including baseline iPhone 17)
In the second half of 2026, the iPhone 17 lineup is still the latest in Apple’s creation and innovation. While these models are available brand-new, the refurbished iPhone 17, 17 Pro, 17 Pro Max, 17e, or iPhone Air will all come at a much lower price and in good shape since they haven’t been used for long, and you’d still get the same iOS updates as the brand-new ones.
If, on the other hand, the phone is not going to be used for any AI purposes or the purchase is limited by a fixed budget, iPhone 14 Pro and Pro Max are good choices. These two models are good for everyday basic tasks and even some heavy gaming. These are the iPhone models that will give you reliable performance and have at least 2-3 years of iOS updates coming to them:
- iPhone 14
- iPhone 14 Plus
- iPhone 14 Pro
- iPhone 14 Pro Max
- iPhone 15
- iPhone 15 Plus
iPhone 13 Series: Worth Buying With Caveats
While the iPhone 13’s entire lineup is expected to remain supported with iOS updates until 2027 or even 2028, we didn’t include it in our list for technical reasons. While the iPhone 13, 13 mini, 13 Pro, and 13 Pro Max are going to get the newest iOS for another year, the slowdown that these iOS updates cause in these models immediately disqualifies them from running.
While the iPhone 13 lineup is still viable and still loved by many, we do advise proceeding with caution with this generation.
The iPhone 13 series can be a reasonable choice as a first iPhone or a budget secondary device, with the understanding that its AI capabilities are limited and its remaining support window is shorter than newer generations.
