Why do old flagship phones get cheaper right after a launch?
Every September and October, a new run of flagships lands, iPhones, Pixels, Galaxies, and the phones sitting one generation back quietly get discounted within days. Retailers need shelf space and network stores need a reason to point you at older flagship phones instead of letting stock sit.
Networks do the same thing with contract pricing. Old flagship phones that were £45 a month in August can drop to £30 or less once the new model takes over the display table, even though the hardware has not changed at all.
How much cheaper do old flagship phones actually get?
It varies by model and by how hyped the replacement is, but a drop of £150 to £300 off the outright price within the first month of a new launch is common for last year’s equivalent tier. On contract deals, the monthly saving is usually smaller in cash terms but adds up over eighteen or twenty four months. Which?’s rolling deals roundup is a decent way to sanity check current prices before you commit.
The Galaxy S25+ is a decent recent example. Its average price fell once the S26 was announced, with retailers competing to shift remaining stock. That pattern repeats every year, on nearly every brand, right on schedule.
Apple, Samsung and Google all run roughly the same playbook, even if the exact discount differs. Apple tends to move the slowest on price but often keeps selling the previous model brand new at a permanently lower price point once the new range lands. Samsung and Google lean harder on short term retailer discounts that fade after a few weeks, so timing matters more with those two.
What do you actually give up buying an old flagship phone?
Mostly bragging rights. The processor is a generation behind, which matters for heavy gaming or intensive editing, but makes little practical difference for calls, messaging, browsing and most apps. A certified refurbished older flagship can push the saving even further if a fully new unit is not a priority for you.
Camera hardware barely moves year to year on the mid and lower tiers of a flagship range, so photo quality is close to identical in most conditions. Software support is the one area worth checking properly. Look up how many years of updates the manufacturer promises from the phone’s original launch date, not from when you buy it, since that clock is already ticking.
Key takeaways
- Old flagship phones typically drop in price within days of the newer model’s launch, not weeks.
- Outright discounts of roughly £150 to £300 are common for the previous generation’s equivalent tier.
- You usually keep the same screen, camera hardware and build quality, and lose only the newest chip and one or two softwar only features.
- Buying outright and pairing an old flagship phone with a SIM only deal is often the cheapest route overall.
When is the best time to buy an old flagship phone?
The first two to four weeks after a new flagship launch tends to be the sweet spot, once initial discounts land but before stock of the older model starts running low on the most popular colours and storage sizes. Waiting longer sometimes finds even deeper clearance prices, but the specific configuration you want may have sold out.
If you can, hold off on any upgrade until you see the new model’s UK launch date confirmed, then move quickly. It is about as close to a guaranteed win as this market gets: a predictable price drop, on a predictable schedule, on a phone you can already hold and test in store. Our own guide to deciding whether any launch is worth upgrading for covers the other side of this decision.
Should you pair old flagship phones with SIM only or a contract?
Buying an old flagship phone outright and adding a rolling SIM only plan almost always beats a fresh 24 month contract on the same handset, since you are not paying interest baked into the monthly price. It also means you can switch networks whenever a better SIM only deal appears, without waiting out a long lock in.
If the upfront cost is the sticking point, some networks still offer 0% finance specifically on older flagship phones once a new generation lands, since they would rather sell the stock than write it off. Ask directly, since it is not always advertised on the main deals page.
Does trading in your current phone change the maths?
It can tip the balance further in favour of an old flagship phone. Trade in values also dip once a new generation launches, since your current handset is now two generations behind rather than one, so there is an argument for trading in just before the new phones arrive rather than after. Check what actually affects trade in value before you accept the first quote.
Get a couple of trade in quotes before you commit to buying anything. The gap between the best and worst offer for the same phone, in the same condition, is often larger than people expect, and it can easily wipe out whatever you saved on the old flagship phone itself.
Roo’s rule of thumb: sort the trade in first, buy the old flagship phone second. Doing it the other way round tends to leave money on the table.
Frequently asked questions about buying old flagship phones
- Are old flagship phones as reliable as new ones?
- Yes, assuming they are sold as new or as manufacture certified refurbished stock. Reliability is about build quality and battery health, not the launch date.
- Do old flagship phones still get security updates?
- Usually, but check the manufacturer’s update policy from the phone’s original release date, since a phone bought a year late has less update runway left.
- Is it better to buy an old flagship phone SIM free or on contract?
- SIM free plus a separate SIM only plan is usually cheaper over time, though a contract can help if you cannot pay the full price upfront.
- Will an old flagship phone work on 5G?
- Any flagship from the last three to four years supports 5G on UK networks, so this is rarely a real limitation.
- How do I find the best price on an old flagship phone?
- Compare network stores, the manufacturer’s own refurbished store and independent retailers, since prices can vary by more than £100 for the same model and condition.
