Best Used Phones Under $600: Updated Buying Guide

Last updated: August 2026. Prices below are ranges observed across US listings and move month to month — treat them as a starting point, not a quote.

Somebody paid $580 for a used Galaxy S25 last spring when a Pixel 8 Pro in equal condition was sitting at $430 two listings down. The S25 is the newer phone. It is not, for most people, the better $580.

That gap is what this tier is really about. Between $400 and $600 you’re shopping two-to-three-year-old flagships, and the models cluster so tightly on performance that the spec sheet stops being a useful tiebreaker. Something else has to decide it.

Why $400 to $600 is the best value in used phones

Above $600 you’re paying a premium for recency, and the phone you get is marginally faster than one costing two hundred less. Below $400 you start hitting phones with short update runways, older camera hardware, and batteries that have done real work.

In between sits the sweet spot: flagships that launched at $800 to $1,200, now discounted by depreciation rather than by compromise. The camera systems are excellent. The processors are still comfortable for another four or five years. The build quality is the good stuff — titanium or aluminium frames, proper water resistance ratings, high refresh displays.

What you’re buying at this price is a phone that was expensive when it was new, and the only thing that’s changed is the calendar.

The number that should decide your pick

Here’s the thing nobody puts on a listing: how many years of security patches this phone has left.

It’s the most consequential spec in the used market and the one buyers ignore most. A phone that stops receiving updates doesn’t die. It just quietly becomes a worse place to keep a banking app, and eventually apps start requiring an OS version it can’t run.

The support policies vary more than you’d expect between manufacturers, and even between generations of the same manufacturer:

Phone	Launched	Update support ends around	Years left from now
Pixel 9	Aug 2024	2031	~5
Galaxy S24	Jan 2024	2031	~5
Pixel 8 / 8 Pro	Oct 2023	2030	~4
iPhone 15 / 15 Pro	Sep 2023	~2029 (est.)	~3
iPhone 14 Pro	Sep 2022	~2028 (est.)	~2
Galaxy S23 / S23 Ultra	Feb 2023	2028 (security)	~2

Google publishes its Pixel update commitment directly, and Samsung maintains a security update policy page listing which models are on which cadence. Apple has never published a formal window, which is why the iPhone rows above are estimates — historically iPhones have received major iOS releases for roughly five to six years, and the XR and XS generation landing at iOS 18 fits that pattern.

Divide price by years remaining and the rankings shuffle considerably. That $430 Pixel 8 Pro works out to roughly a hundred dollars a year of supported life. A $560 Galaxy S23 Ultra, with security updates winding down in 2028, works out to nearly three times that.

Specs aren’t nothing. But at this price, everything is fast. Runway is the differentiator.

The picks

Pixel 8 Pro — the best value in the tier, by some distance

Commonly $400 to $480 depending on storage and condition.

Four years of guaranteed updates left, a 6.7-inch LTPO display that scales properly, and a camera system that still holds up against phones costing twice as much used. The Tensor G3 isn’t the fastest chip in this list — it isn’t close — but “not the fastest” at this tier means it opens apps instantly instead of instantly.

The honest drawbacks: Tensor runs warm under sustained load, and battery life is good rather than great. If you game seriously, this isn’t your phone. For everyone else, the combination of price and remaining support is the strongest argument in the category, and it isn’t particularly close.

The Pixel 8 (non-Pro) sits around $320 to $380 with the same support window and a smaller, slightly less capable camera setup. If your budget is really $400 rather than $600, take that and put the difference toward a case and a battery service later.

Galaxy S24 — the long-haul Android choice

Typically $420 to $520.

Seven years of OS and security updates from a January 2024 launch means this phone is supported into 2031, which is longer than most people keep a phone by a wide margin. US units carry the Snapdragon 8 Gen 3, which is genuinely quick and stays quick under load.

The 6.2-inch size is either the appeal or the dealbreaker — it’s one of the few remaining flagships you can operate one-handed. Samsung’s software is heavier than Google’s, and there’s more of it than some people want, though most of it can be disabled.

If you want the same support runway in a larger body, the S24+ runs about $80 to $120 more.

iPhone 15 Pro — the iPhone to buy in this tier

Usually $500 to $600, occasionally lower with cosmetic wear.

The 120Hz display, the titanium frame, the Action Button, USB-C, and the A17 Pro. This was a $999 phone two and a half years ago and it does not feel like a compromise now. Roughly three more years of iOS releases is the realistic expectation.

Worth knowing before you buy: US models of the iPhone 14 generation and later have no physical SIM tray at all. They’re eSIM-only. Most US carriers handle eSIM fine, but it removes the SIM-tray liquid contact indicator from your inspection routine, so you lose one of the standard water-damage checks.

Pixel 9 — if you want the newest thing in the tier

Around $450 to $550.

Support into 2031, a meaningfully better thermal design than the Pixel 8 line, and the same camera philosophy that makes Pixels easy to shoot with. It’s the newest phone on this list that reliably lands under $600.

Straight comparison against the Pixel 8 Pro: you get one extra year of support and a nicer chassis, you give up the Pro camera’s telephoto reach, and you pay roughly a hundred dollars more. I’d take the 8 Pro. Reasonable people take the 9.

iPhone 15 — the value iPhone, with one real caveat

Roughly $400 to $470.

USB-C, the Dynamic Island, the A16, and the 48MP main sensor. Solid phone, fair price.

The caveat is the display: 60Hz. Apple held 120Hz back for the Pro line through this generation, and after using anything smoother, a 60Hz panel is the sort of thing you notice every day and can’t stop noticing. If you’re coming from an older iPhone you may never register it. If you’re coming from any recent Android flagship, budget for irritation.

Galaxy S23 Ultra — brilliant hardware, expiring clock

Often $480 to $580, which is the problem.

The 200MP sensor, the 10x periscope, and the built-in S Pen are still standout features, and nothing else in this tier does what the S Pen does. As a piece of hardware it’s arguably the most capable phone on this page.

But the S23 generation was covered by Samsung’s older policy — four OS upgrades and five years of security from a February 2023 launch. That puts the end of security support around 2028. Paying near the top of the tier for the shortest runway on the list is a poor trade unless you specifically need the pen or the zoom, in which case buy it knowingly and plan to replace it sooner.

iPhone 14 Pro — the floor of the tier

Around $380 to $440.

120Hz, the Dynamic Island, and a camera system that’s aged well. It’s Lightning rather than USB-C, and it has the shortest iOS runway of the Apple options here.

Buy it if the price drops toward $380 and you’re comfortable replacing the phone in two or three years. Above $440 the iPhone 15 makes more sense.

US-specific traps that cost people real money

This tier is where imported and carrier-tied stock starts showing up in volume, and both cause problems that aren’t visible in photos.

International variants of Samsung phones. Someone imports an SM-S921B instead of the US SM-S921U to save eighty dollars. The phone works. Then they discover that VoLTE isn’t certified on their carrier, and since the US 3G networks shut down in 2022, no VoLTE means no voice calls on some networks. Data works fine, which makes it confusing for a day or two before it becomes obvious. Check the model suffix against the US variant before you buy anything that seems suspiciously cheap for its model.

mmWave, or the lack of it. Some carrier-specific variants include mmWave hardware and others don’t. It matters less than the marketing suggested it would, but if you’re on a network that leans on it in your city, check the exact model number rather than the phone’s name.

Carrier locks. On iPhone, Settings > General > About > Carrier Lock should report no SIM restrictions. On Android it’s inconsistent enough that the reliable test is putting your own SIM in at the meetup and watching it register. A locked phone at an unlocked price is one of the most common overpays in this bracket.

Financed phones. A device still on someone’s carrier instalment plan can be blacklisted months after you buy it, when the payments stop. The IMEI checks clean today because it is clean today. Ask whether the phone was bought outright, and treat evasiveness as an answer. We cover this and the rest of the paperwork risks in our guide to buying a used iPhone safely.

Before you pay for anything in this tier

At $400 to $600 the inspection matters more than it does at $150, because the downside is bigger.

The short version: verify the IMEI in three places, check parts and service history on iPhone, check battery health against a believable story, run the three-colour screen test for burn-in, enroll your own biometrics rather than watching the seller’s work, and complete setup on your own account with your own SIM before money moves.

The long version is our fifteen-point inspection checklist, which is worth screenshotting before a viewing.

If you’d rather pay a premium and skip the inspection entirely, certified refurbished units in this tier come with a new battery and a warranty — our comparison of used, refurbished, and open-box covers when that premium is worth paying.

What I’d skip in this tier

Taking a position, because “it depends” isn’t useful here.

Last year’s flagship at the top of the budget. A used Galaxy S25 or iPhone 16 Pro at $580 to $600 is a fine phone bought at the worst point on its depreciation curve. Wait two months past the next model announcement and the same phone drops noticeably.

Anything with under two years of support left. No matter how good the hardware is. You’ll be shopping again before the phone feels old, which means you paid flagship money for a mid-cycle rental.

Imported variants to save under $100. The savings evaporate the first time a network feature doesn’t work and you’re troubleshooting a phone that was never certified for your carrier.

Ultra and Pro Max models purely for the size. They’re heavier, they cost more used, and in this tier the money is better spent on a newer generation of the standard model.

Common mistakes to avoid

Shopping by model name instead of by support runway. The table near the top of this page reorders most people’s shortlist.
Assuming a newer phone is the better buy. In this bracket it’s frequently the worse dollar-per-year.
Paying an unlocked price for a carrier-locked device. Test with your own SIM, at the meetup.
Overlooking the eSIM question on recent iPhones. US models from the iPhone 14 generation on have no tray, which changes both your carrier setup and your inspection routine.
Ignoring battery health because the phone feels fast. Speed and battery age are unrelated. A battery service is a real cost that belongs in your offer.
Buying at the top of the tier the week before a launch event. Prices move within days of an announcement.

FAQ

Is a two-year-old flagship better than a new mid-range phone at the same price?

Usually yes, on camera quality, display, build, and processor. The exception is software support — a new mid-range phone from Google or Samsung may carry a longer update runway than a used flagship, so check both before deciding.

Which phone on this list has the longest software support?

The Pixel 9 and Galaxy S24, both supported into roughly 2031. The Galaxy S24 is generally the cheaper of the two used.

Should I buy an iPhone or an Android in this tier?

If you already own AirPods, an Apple Watch, or a Mac, the iPhone 15 Pro is the straightforward answer. If you don’t, the Pixel 8 Pro delivers more phone per dollar and more years of support, and it’s the pick I’d make with my own money.

How much should a used phone’s battery health be at this price?

Above 85% at $400 to $600. Below that, subtract the local cost of a battery replacement from your offer rather than walking away — on most of these models it’s a modest service, and a fresh battery on a well-kept phone is a good outcome.

When is the best time to buy in this tier?

Two to eight weeks after a new flagship generation is announced, when the previous generation’s owners upgrade and supply jumps. Prices in this bracket move on supply far more than on condition.

Does ExploreFrag verify the phones listed on it?

ExploreFrag connects buyers and sellers directly, so listings come from the individuals selling them. Run the checks yourself regardless of how good the description reads.

Take the two models you’re torn between, look up when each stops getting security updates, and divide the asking price by the years remaining. That number settles more arguments than any camera comparison, and it takes about ninety seconds.

When you’ve got a shortlist, see what’s currently listed in this price range on ExploreFrag and message a couple of sellers with specific questions about model number and battery health.
