When Is the Best Time to Sell Your Samsung Galaxy Phone?
Timing matters when selling any phone, but it matters more for Samsung Galaxy phones than most people realise. Samsung runs a fairly predictable annual release cycle, which means the months before and after each Galaxy S launch are very different markets for sellers.
If you've got a Galaxy S24, S23, or older model sitting in a drawer or about to be replaced, picking the right month to sell can make a meaningful difference to what you get.
This guide covers the best time to sell your Samsung Galaxy phone in the UK, the seasonal patterns that affect resale value, and how to lock in a good price before depreciation kicks in. If you're already ready to move on, you can check your Samsung Galaxy value here in under a minute.
Why timing affects Galaxy phone resale value
Samsung launches new Galaxy S models each year at its first Galaxy Unpacked event, typically held in late January or February. The Galaxy S26 series launched in February 2026, the S25 in January 2025, and the S24 in January 2024. Samsung also runs a second Unpacked event in summer for foldables and Galaxy Watches, which affects the timing picture too.
Once Samsung announces a new Galaxy S series, trade-in valuations for older Galaxy phones adjust within days. Resellers update their pricing to reflect the new lineup, and older phones 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 just got replaced - so the Galaxy S25 will lose value fastest once the S26 launches, and the same pattern applies in each year.
The best time of year to sell your Galaxy phone
Sellers in the UK see fairly predictable patterns across the year. Here's how it tends to break down:
Autumn to early winter: the strongest window
This is when prices are at their best for older Galaxy S 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 after the next Galaxy S launches, selling before Samsung's first Unpacked of the year (usually in late January or February) is the smartest move.
After the Galaxy S launch: the drop
Once Samsung announces the new Galaxy S series, trade-in prices for older Galaxy phones 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-Unpacked window, selling sooner still tends to beat waiting, since prices often keep softening through spring as more people upgrade.
Late spring to early summer: a soft floor
By late spring, the market has absorbed the new Galaxy S lineup and prices stabilise. The drop is largely done, and trade-in values hold fairly steady. Not the best time to sell, but not actively the worst either.
Mid-summer: the second drop for foldables and A-series
Samsung's summer Unpacked event (usually in late July or early August) brings new foldables and sometimes refreshed A-series phones.
If you've got a Galaxy Z Fold or Z Flip, or a recent A-series model, this is your equivalent of the January drop. For Galaxy S owners, the impact is smaller - the summer event doesn't usually affect S-series values directly.
Autumn: small Christmas uptick approaching
From October onwards, demand for refurbished and second-hand Galaxy phones starts to rise as Christmas approaches. Trade-in values can recover slightly during this window, particularly for popular models in good condition.
December: festive demand peaks
Galaxy phones are popular Christmas gifts, and refurbished demand peaks in early-to-mid December. This is often a strong window for selling models that have been holding their value well.
Should you sell before or after a new Galaxy phone launches?
Almost always, before. The weeks leading up to Samsung's first Unpacked of the year are when your Galaxy holds the most value. Once the new lineup is announced, even Galaxy phones in pristine condition lose ground because the whole market resets around the new pricing.
The exception is for older Galaxy phones that have already absorbed most of their depreciation. A Galaxy S20 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 Samsung's calendar and more about whether the phone still works reliably and gets Android updates.
Other factors that affect when you should sell
Timing isn't just about Samsung's release schedule. A few personal factors matter too:
- Software support: Once Samsung drops your model from major Android updates, demand falls sharply. Selling while your phone still receives updates protects its value. Our guide on how long Samsung Galaxy phones last covers which models are still supported.
- Battery health: Galaxy phones with worn batteries fetch significantly lower trade-in offers. If your battery is showing real wear, selling sooner usually beats waiting.
- Condition: Scratches, cracked screens, and worn USB-C ports all reduce trade-in offers. A phone 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 phones.
Galaxy phone values can move quickly around the early-year Unpacked 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 autumn or early winter before Samsung's first Unpacked of the year. If you've already missed that window, sell as soon as you've decided you're done with the phone - waiting through spring rarely helps.
And if you're upgrading anyway, pairing a sale with a refurbished purchase keeps your overall cost down. You can browse refurbished Samsung Galaxy phones here to see what your trade-in could go toward. Our guide on the best refurbished Samsung Galaxy phone to buy in 2026 covers each tier in detail.
Galaxy phones don't hold value forever, but with the right timing you can get a fair return and put it straight toward your next upgrade.
