When Is the Best Time to Sell Your iPhone?

Timing matters when selling any phone, but iPhones in particular follow a very predictable annual cycle. Apple's autumn release pattern is one of the most consistent in tech, which means the months before and after each new iPhone launch are very different markets for sellers.

If you've got an iPhone you're thinking of upgrading from, picking the right month to sell can make a noticeable difference to what you get for it.

This guide covers the best time to sell your iPhone in the UK, the seasonal patterns that affect resale value, and how to time things to maximise your trade-in. If you're ready to move on now, you can check your iPhone trade-in value here in a couple of minutes.

Why timing affects iPhone resale value

Apple has launched a new iPhone lineup every autumn since 2007 (with one exception for the iPhone 12 in 2020). The keynote is typically held in early-to-mid September, with the new phones on shelves a week or two later. The pattern is so consistent that you can plan around it without needing to guess.

Once Apple announces the new lineup, trade-in valuations for older iPhones adjust within days. Resellers update their pricing to reflect the new models, and older iPhones start to look less attractive to buyers who could put that money toward something newer.

The drop is usually most severe for the model that's just been replaced - so the iPhone 17 series will lose value fastest once the iPhone 18 launches in September 2026.

Apple has also added a mid-cycle "e" release each spring in recent years (the iPhone 16e in early 2025, the iPhone 17e in early 2026). This affects entry-level iPhone pricing more than the flagship Pro models, but it's worth being aware of if you're selling an older standard iPhone.

The best time of year to sell your iPhone

UK sellers see fairly predictable patterns across the year. Here's how it tends to break down:

Spring to mid-summer: the strongest window

This is when prices are at their best for older iPhone models. Demand is steady, supply hasn't been disrupted by a new launch, and trade-in valuations haven't yet adjusted for the next generation.

If you're planning to upgrade in autumn, selling before Apple's September keynote is the smartest move.

Late spring (April to June) is often a particularly strong window, partly because new iPhone rumours haven't fully ramped up yet and buyers still see current-generation iPhones as the latest available.

Autumn after the iPhone launch: the drop

Once Apple announces the new iPhone lineup, trade-in prices for older iPhones typically fall within days. The size of the drop varies by model, but it's usually most noticeable on the immediately-previous generation.

If you've missed the pre-launch window, selling sooner still tends to beat waiting, since prices often keep softening through autumn as more people upgrade.

November to early December: a small Christmas uptick

iPhones are popular Christmas gifts, and refurbished demand rises with it. Trade-in values can recover slightly during this window, particularly for popular models in good condition. It's not a major bounce, but it's enough to mean late November or early December is usually better than mid-October if you've already missed the pre-launch window.

January to early spring: steady decline

After Christmas, prices drift downwards gradually as the current generation continues to age. There's no dramatic drop, but each month brings you closer to the next September event and the next round of depreciation. The arrival of a spring "e" model can also nudge prices on older standard iPhones down slightly.

Should you sell before or after a new iPhone launches?

Almost always, before. The weeks leading up to Apple's September keynote are when your iPhone holds the most value. Once the new lineup is announced, even iPhones in pristine condition lose ground because the whole market resets around the new pricing.

The exception is for older iPhones that have already absorbed most of their depreciation. An iPhone X or earlier has already lost most of what it's going to lose, so the impact of a new launch is smaller. In that case, the urgency is less about Apple's calendar and more about whether the phone still works reliably and gets iOS updates.

Other factors that affect when you should sell

Timing isn't just about Apple's release schedule. A few personal factors matter too:

• Battery health: iPhones with worn batteries fetch significantly lower trade-in offers. If your battery is showing real wear, selling sooner usually beats waiting.
• iOS support: Once Apple drops your model from major iOS updates, demand falls sharply. Selling while your iPhone still receives updates protects its value. Our guide on how long iPhones last covers which models are still supported.
• Condition: Scratches, cracked screens, and worn ports all reduce trade-in offers. An iPhone in good shape now won't necessarily still be in good shape in six months.
• Original box and accessories: Complete devices tend to be graded more favourably, so selling while you still have the original kit can lift your offer.

Trade in vs sell privately: which is better?

Private selling sometimes pulls a higher headline price, but it comes with hassle: photos, listings, messages, no-shows, and the risk of returns or disputes. Specialist trade-in services price devices based on current market demand and pay quickly, which is usually the better trade-off for iPhones.

iPhone values can move quickly around the September launch window, so a fast, predictable sale often beats waiting weeks for a private buyer - particularly if you're trying to sell in the run-up to a new launch.

The simple rule for selling at the right time

If you're planning to upgrade, sell in spring or summer before Apple's September keynote. If you've already missed that window, sell as soon as you've decided you're done with the phone - waiting through autumn rarely helps.

If you're upgrading anyway, pairing a sale with a refurbished purchase keeps your overall cost down. You can browse refurbished iPhones here to see what your trade-in could go toward.

iPhones hold value better than most phones, but they don't hold it forever. With the right timing you can get a fair return and put it straight toward your next upgrade.
