Four years is a long time in smartphone marketing and a surprisingly short time in actual smartphone use. The iPhone 14 Pro Max arrived in 2022 with a 6.7-inch OLED display, Apple’s then-new Dynamic Island and a 48MP main camera. In 2026, it is no longer new, but that does not automatically make it obsolete.
For owners watching another Apple launch cycle approach, the useful question is not whether a newer iPhone will be faster. It will. The question is whether the difference is large enough to justify replacing a phone that may still be worth several hundred pounds.
The four-year flagship test
A good way to judge an older flagship is to ignore its age for a moment and test the things that matter every day: battery endurance, camera reliability, app performance, storage, display condition and software support. If the phone still gets through the day, takes the photos you want and never feels slow, its practical value to you may be higher than its trade-in value.
That is especially true because recent flagship upgrades have become more incremental. The jump from a mid-range device to a modern Pro phone can be enormous; the jump from one recent Pro generation to the next is often much smaller in normal use.
But the iPhone 14 Pro Max still has real cash value
The other side of the calculation is depreciation. SellMyPhone’s comparison page showed a leading offer of about £336 for a working iPhone 14 Pro Max when checked for this article. Its price-tracking data projects a possible fall of around £65 over the next three months if typical patterns continue. Those are market estimates rather than guaranteed future prices, but they illustrate the cost of waiting.
If another Apple launch has already convinced you to upgrade, checking what you could get if you sell your iPhone 14 Pro Max now gives you a much more useful number than simply looking at the retail price of the next phone.
When keeping it makes more sense
- The battery still comfortably lasts your normal day.
- You are happy with the camera and do not regularly use the newest computational-photography features.
- The phone has enough storage and remains physically sound.
- You would be upgrading mainly because a new model exists rather than because the current one is failing you.
When selling starts to make sense
The case for selling becomes stronger when two things are true at the same time: you already want the replacement and the old phone still has a meaningful resale value. Waiting until a phone becomes frustrating can maximise the years of use, but it also means accepting that more of its remaining cash value will disappear.
There is no universally correct replacement age. A four-year-old flagship that still works beautifully can be a better financial choice than a brand-new phone. Equally, someone who knows they will upgrade this autumn may prefer to recover £300-plus now rather than keep the device through another depreciation cycle.
The sensible pre-launch habit
Before deciding, compare the live market rather than relying on one manufacturer’s trade-in figure. SellMyPhone.co.uk compares offers from multiple UK recyclers, so the old phone’s value can be treated as part of the upgrade budget.
The iPhone 14 Pro Max passes the 2026 usefulness test surprisingly well. Whether it passes your personal value test depends on what the next phone fixes, how much you will actually notice those changes, and how much cash you are prepared to let the current phone lose while you wait.
