Buying a Refurbished Android Phone: Samsung, Pixel or Xiaomi, What Matters Per Brand

With Apple the question is fairly relaxed, because an iPhone generation gets supported pretty evenly across the board. What that means on the Apple side of a used purchase is covered in our refurbished iPhone buying guide. Android doesn't work that way. That's exactly the point where a refurbished Android phone turns into a bet that a refurbished iPhone never is. Every manufacturer sets its own window, then tiers it by device class, and occasionally changes it mid-lifecycle.

That's the real difference. Not the camera, not the chip, not screen brightness, but a deadline no brochure ever mentions.

And almost nobody spells it out. Most guides write "check the update policy" and leave you there. The maths isn't hard, though. Take the quoted window, subtract the time since launch, and whatever's left is how long your second-hand device keeps getting patches. That's the sum we're running here for three specific models.

According to Samsung, Galaxy devices have received up to seven years of security updates since January 2024, monthly on flagships like the Galaxy S line and quarterly on the mid-range A series (accessed 13.08.2026). Samsung adds a caveat on that same page: availability and timing can vary by market, carrier and model.

The words doing the heavy lifting are "up to". All three Galaxy S24 models get seven years of Android, One UI and security updates per Android Authority. The A series is a different story: only the newest models, the A16 5G, A26 5G, A36 5G and A56 5G, reach six years, an older model like the A54 5G tops out at four, and some A models get only three (accessed 13.08.2026). So if you spot a cheap refurbished A model and you're carrying the seven-year headline in your head, you could be budgeting several years that aren't there, not just one.

Doing the maths on the Galaxy S24

The Galaxy S24 hit German retail on 31 January 2024 (source: gamestar.de). By 13.08.2026 that's roughly two years and six and a half months gone, out of 84 months total. Which leaves something like four years and five months, so support until around January 2031.

For a used device that's a genuinely comfortable buffer. Longer than what plenty of brand-new mid-rangers ship with.

At asgoodasnew, the Samsung Galaxy S24 with 128GB in onyx black, condition grade Sehr gut, is listed at 389 euros as of 13.08.2026.

One extra thing worth checking on Samsung: whether the listing comes from the regular refurbished trade or from Samsung's own programme. We pulled those apart in Samsung Certified Re-Newed in Germany, and the specific things to verify before you click are in our Samsung buying checks.

Google states that Pixel 8 and every later model, including the Pixel 8a, get updates for seven years, counted from the day the device first became available in the Google Store (accessed 13.08.2026). The same page lists a second, shorter group: Pixel 6, 6 Pro, 6a, 7, 7 Pro, 7a and Pixel Fold get five years.

That split is worth real money when you're buying used. A refurbished Pixel 7 looks almost identical to a Pixel 8 in a listing, costs less, and still carries a noticeably shorter runway. Shop on price alone and you quietly buy yourself a shorter device life.

What I find genuinely useful here is how specific Google is about the start date. "From when the device first became available on the Google Store in the US" is something you can check. Samsung names no equally precise anchor, and as far as this research could tell, neither does Xiaomi.

Doing the maths on the Pixel 8a

The Pixel 8a was announced on 14 May 2024 and was available essentially straight away (Google Blog Germany). By 13.08.2026 that's about two years and three months gone, again out of 84 months. Roughly four years and nine months left, so support until around May 2031.

That gives the Pixel 8a the longest remaining window of the three models in this piece. It's also the cheapest of them.

One point that rarely shows up in Pixel buying advice: Google's iFixit partnership for Pixel parts is still running into 2026, while Samsung walked away from that route in 2024. More on that in a moment.

Honestly, this is where it gets murky, and the murkiness is itself a buying criterion.

Reporting from tech-ish and Gizmochina, both citing Xiaomi's Security Center, places the Xiaomi 14 in the manufacturer's top support tier: four major Android or HyperOS version updates plus five years of security patches (accessed 13.08.2026). That figure is secondary-sourced. Xiaomi's own device table in its Security Center wasn't retrievable in a form that allowed a direct quote check during this research. We'd rather write that plainly than claim a manufacturer source we never actually saw.

Five years of patches is two fewer than Samsung or Google. On a brand-new phone you'd barely notice. On a two-year-old used one it roughly halves what's left.

Doing the maths on the Xiaomi 14, twice

Here's the part nobody handles cleanly. The Xiaomi 14 was unveiled in China on 26 October 2023. The German launch didn't follow until late February 2024, with retail availability from around early March (notebookcheck). Which of those two dates Xiaomi's internal counter uses is something the company hasn't published anywhere we could find. So, both scenarios:

• Anchored to China, 26.10.2023. Probably the likelier one, since manufacturers usually count from first global release. That's about two years and nine and a half months gone out of 60. Remaining: roughly two years and three months, so patches until around October 2028.

• Anchored to Germany, around March 2024. The buyer-friendly reading. About two years and five months gone. Remaining: roughly two years and seven months, until around March 2029.

Pick either date and the conclusion holds: the remaining window is under half of what a Galaxy S24 or a Pixel 8a from the same launch year still has. That's the sharpest number in this whole comparison.

Second trap with Xiaomi, the sub-brands. Redmi and Poco sit under the same corporate roof but not under the same support tier. If the series logic is new to you, Talk-Point has a usable rundown. For a refurbished purchase it boils down to one habit: read the model, not the brand name.

At asgoodasnew, the Xiaomi 14 with 256GB in jade green, condition grade Wie neu, is listed at 539 euros as of 13.08.2026.

The table is arithmetic built on publicly quoted windows, not a promise. Manufacturers can change schedules, and Samsung itself says availability varies by market and model.

Samsung and Google lead on software support. On the repair side the picture isn't a mirror image, it's just messier.

Samsung runs its own self-repair programme in Germany with parts supply (Samsung Newsroom Germany). At the same time, iFixit ended its role as Samsung's official parts distributor in May 2024, citing high part pricing and strict quantity limits for repair shops (accessed 13.08.2026). So the programme exists, and a repair advocacy organisation went public with criticism of its terms.

Google's iFixit partnership for Pixel parts is still active into 2026.

Xiaomi? This research found no official German spare-parts self-repair programme comparable to Samsung's. That is a stated gap in what we could verify, not a claim that no such thing exists. In practice it means that if you're planning around repairability on a Xiaomi device in Germany, you're mostly looking at independent workshops.

Underneath all three sits a legal floor that took effect on 20 June 2025. The EU Ecodesign regulation requires manufacturers to supply critical spare parts for at least seven years after a model leaves the market, and to guarantee at least five years of operating system updates, regardless of brand (accessed 13.08.2026). It applies to devices placed on the market from June 2025 onward, so not retroactively to your 2024 second-hand phone. Still the best news in this article, because over time it narrows the gap between brands.

The brand decides your update window. The seller decides almost everything else.

Read the battery figure, don't trust it. refurbed states a minimum of 85% battery capacity for smartphones in its Excellent, Very good and Good categories, and 90% for Premium. Back Market also guarantees at least 85%, while asgoodasnew states a flat minimum of 80% regardless of cosmetic grade (all accessed 13.08.2026, seller-stated figures). Those are listing thresholds the seller commits to, not measurements of the unit that lands on your doorstep. There's more on that in our piece on refurbished battery quality.

Condition grades don't transfer between sellers. "Very good" at one shop isn't automatically "Very good" at the next, because every retailer defines its own scale. How the common tiers line up is unpacked in refurbished condition grades explained.

Check the statutory warranty properly. Since the German sales-law reform of 1 January 2022, according to IT-Recht Kanzlei, a mention buried in the terms and conditions is no longer enough to cut statutory warranty on used goods to one year. Buyers have to actively agree via a dedicated checkbox (accessed 13.08.2026). What separates a manufacturer guarantee from statutory warranty is covered in our guide to warranty and guarantee on refurbished phones.

VAT missing from the invoice isn't an error. Under the German margin scheme for used goods (§25a UStG), a dealer taxes only the resale margin and therefore doesn't itemise VAT separately (orgamax). Private buyers are unaffected, but business buyers can't claim input tax from such an invoice.

And the seller itself? In a test by Stiftung Warentest, six of nine refurbished shops tested earned a rating of "gut" (test dated January 2025). That test judged shops and service, though, not how long individual brands last. So no conclusion about Samsung, Google or Xiaomi can be pulled out of it, and we're not pulling one.

There's no winner's rosette at the end of this, because we tested nothing, and a price comparison site doesn't test anything. What we can hand you is the decision logic.

If the longest remaining window at the lowest price is what you care about, current listings make the Pixel 8a hard to argue with. 259 euros for a device with close to five years of updates still on the clock is the most striking number in this article.

If you need accessories, repair routes and a very wide model choice, Samsung is the more practical pick, with the one caveat that you check the model tier before you rely on seven years.

And Xiaomi? For people who want the most hardware per euro and tend to replace a phone after two or three years anyway. As a long-hauler, a two-year-old Xiaomi 14 is the weakest of the three right now, at least going by the figures that are publicly available.

One habit worth building before you buy a refurbished Android phone? Take the exact model name. Look up its launch date. Subtract the window, and do it before the price talks you out of checking. That sum takes two minutes and tells you more than any star rating. Current offers from every connected seller are in the Refurbito price comparison.
