Why we picked it #1

This listing stands out as the best value because you get a solid Galaxy S23+ (256GB, refurbished to good condition) from a top-rated, highly trusted seller. You're fully covered with a year-long seller warranty, a generous 30-day return window, and the comfort of a dependable seller with a nearly flawless track record. The phone is unlocked and comes with an original charger and a premium wall charger—extras you won't always see elsewhere. Compared with cheaper options like the #5 or #3 listings, you gain much stronger post-purchase support (a full year, not just 30 days) and the reliability that comes from a top seller. Versus pricier options in excellent condition, you might see minor signs of wear, but in return, you’re saving a notable amount—while still getting a phone that’s ready for daily use. The only tradeoff: it’s not in like-new condition cosmetically and you don’t get the original box, but for peace of mind and value, it’s one of the smartest picks in the lineup.

Why we picked it #2

You’re paying a bit more here, but what you get is peace of mind and high-end features. This certified refurbished S23+ has double the storage (512GB), is in excellent condition, and is about as close to new as you’ll find. The big win: a full year of manufacturer warranty still left, which is extremely rare on refurbished Galaxy devices—and it puts you years ahead of most listings if you want worry-free use. The seller is one of the top-rated and most trusted, and you get perks like included accessories, OEM charger, and same-day shipping if you’re in a hurry. If you’re eyeing true longevity and want your phone to feel close to brand new, this is hard to beat, especially for heavy photo takers or digital packrats. The main tradeoff is price—it costs more than the top-ranked listing or value picks below, but for what you get (warranty, condition, storage), that extra investment goes directly into a better long-term, hassle-free experience.

Why we picked it #3

If you’re after maximum savings but still want a solid and worry-free experience, this is one of the cheapest S23+ options available. You get 256GB of storage, an unlocked device, and a "Good" refurbished condition—all at a standout price. The seller is highly rated, trustworthy, and includes return shipping, so you’re not taking unnecessary risk. There’s testing verification and a charging cable included, which adds a little extra reassurance. The compromise here: you only have 30 days of seller warranty (far less protection than the top pick or #4), and condition isn’t quite at the “very good” end of the spectrum. If top-tier cosmetics or longer warranty coverage matter to you, you might want to look higher up the list. But, for pure bang-for-buck and reliable seller backing, this option is hard to overlook, especially if you don’t mind a phone that’s seen some use.

Why we picked it #4

You’ll save some money here and get a full year of seller warranty, which is rare on a used phone. This listing is "B Grade" used, meaning you should expect more cosmetic wear than with refurbished options higher in the list (like the top pick), but it’s unlocked and comes from a very reputable seller with sky-high feedback. If long-term peace of mind is a priority, this much warranty is impressive—only the #1 listing offers something similar. However, you get only a generic charging cable (no OEM or fast charger), and since it’s not refurbished, it might feel a bit more… well, used. If cosmetic condition is less important to you than saving money or having lots of backup for a year, this is compelling. It’s a small step down from #1 in terms of overall polish and included extras, but the long warranty balances that out well.

#5

Good - Refurbished

View on eBay

Why we picked it #5

This is the lowest-priced option in the whole lineup, so if your main goal is stretching your dollar, this listing delivers. You'll get a fully unlocked, refurbished Galaxy S23+ with 256GB of storage in "Good" condition, from a top-rated and experienced seller. There’s a 30-day return window and return shipping is covered, so you’re not exposed if something’s off. The tradeoff for this price is in the details: the phone may show more cosmetic wear than the top-ranked listings, and the included charger isn’t original—it’s third party. Also, unlike the #1 or #2 picks, there's no year-long warranty, so you’ll want to check that the phone is in good shape when you get it. Still, for baseline reliability at the lowest cost, this is the “wallet win”—just expect a phone that’s secure and functional, but maybe not quite as “fresh” out of the box.

#6

Samsung Galaxy S23 Plus SM-S916U 256GB Unlocked Very Good Condition

Very Good - Refurbished

View on eBay

Why we picked it #6

Here, you’re getting a “Very Good” refurbished S23+—meaning less noticeable wear and a generally nicer in-hand feel than the standard “Good” refurb options. There’s also a charging cable and SIM ejector included, and the refurbishing process is reliability-certified (ISO9001), which usually means better consistency in battery and appearance. This can be worth the small step up in price over cheaper "Good" condition options like #3 and #5, especially if you want something that feels more premium day-to-day. The seller is very established and highly rated, and there’s a 30-day return period. What you’re trading off is that you don’t get the 1-year warranty found in the #1 pick, and there’s no word on OEM charger or original box. Think of this as the sweet spot between price and appearance: you’re paying a bit more, but you’ll likely get a phone that looks and feels much closer to new, minus the longest-term coverage.

#7

Samsung Galaxy S23+ PLUS 256GB 5G SM-916U1 Factory Unlocked - EXCELLENT

Excellent - Refurbished

View on eBay

Why we picked it #7

This listing brings together a truly excellent refurbished S23+ with a 12-month manufacturer warranty—much longer protection than most. The phone itself is in top condition, comes with a genuine Samsung charger, is professionally tested, and is verified for broad carrier compatibility. You’ll also get fast shipping and direct support if you need it. If you want a phone that both looks and feels nearly new, but don’t need the extra storage of the pricier #2 pick, this is a very safe middle ground. The main reason it ranks a bit lower is price—it's higher than the well-protected #1 pick, but you are getting better cosmetics and warranty coverage than almost all options below it. In short: you’re paying a premium for security and appearance, which pays off if you’d rather avoid any ownership headaches for at least the next year.

Why we picked it #8

This is a solid low-priced choice if you don’t mind that your S23+ was previously used (not just refurbished). You’re covered by a 30-day return policy from a top-rated, extremely well-reviewed seller, and your cost is a step below most others that promise similar trust and return policies. The seller’s attention to detail—cleaned and tested charging port—suggests care, but keep in mind: unlike the higher-ranking refurbished options, there’s likely more cosmetic wear, and you don’t get a charger included. There’s also no long-term warranty here, so this is best if you’re confident you’ll spot any issues in the first month. Basically, you get a dependable deal on a functional, fully unlocked S23+ on a tight budget—but if you want a phone that feels nearly new (with a warranty to back it up), look higher on the list.

Why we picked it #9

This listing is for a refurbished S23+ in excellent condition, so you'll get something that looks and feels very close to new. The seller is top-rated with a lot of experience, and you have a 30-day return window with return shipping paid if anything isn’t right. While you get that premium cosmetic condition, the price is on the higher side compared to the most affordable "Good" refurb or used options—so you’re really paying for that like-new appearance. Also, be aware the included charger isn’t an original Samsung charger, unlike a few listings above. There’s no long seller or manufacturer warranty, which is something you do get with picks like #1 or #2—meaning your post-purchase coverage is mostly just the return window. This is a solid pick if you want a device that feels pristine, but plan to check it over thoroughly in the first month just in case.

Why we picked it #10

If you’re all about the lowest possible price, this is the clear winner—it’s by far the cheapest S23+ in the lineup, fully unlocked and still refurbished to "Good" standard by a very trustworthy, experienced seller. You benefit from a 30-day return window and seller-paid return shipping, so you’re not out of luck if something’s off at first glance. You also do get an original Samsung charger, which is a rare plus at this price. The honest downside: for this much less, you should expect noticeable wear—plus, there’s only a minimal (30-day) seller warranty, so long-term support isn’t included. Basically, this option is about getting into a late-model flagship for as little as possible from a safe seller; if you’re handy with setup and spot issues early, the value here is huge. If you care more about buyer protection or pristine looks, you might want to spend a bit more for one of the listings further up the list.

Samsung Galaxy S23+

Samsung Galaxy S23+: Why Buy Used?

The Galaxy S23+ is Samsung's 2023 flagship -- a capable smartphone with the Snapdragon 8 Gen 2 processor, a 6.6" FHD+ Dynamic AMOLED 2X 120Hz display, and a 50MP+12MP+10MP camera system. Now two generations old, it represents outstanding value on the used market with substantial savings over newer models.

What Makes the Galaxy S23+ a Great Choice

Every Galaxy S23+ has the same core hardware -- the only thing that varies between units is storage capacity. That makes buying used straightforward: you're getting the same phone regardless of who owned it before.

  • Snapdragon 8 Gen 2 processor -- Samsung's 2023 flagship chipset delivers top-tier performance for gaming, photography, multitasking, and everyday use.
  • 50MP+12MP+10MP camera system -- 50MP main, 12MP ultra-wide, 10MP 3x telephoto. Capable of detailed photos and 4K video recording in virtually any condition.
  • 6.6" FHD+ Dynamic AMOLED 2X 120Hz display -- Dynamic AMOLED 2X panel with vivid colors, deep blacks, and smooth 120Hz scrolling. Excellent for media, gaming, and outdoor visibility.
  • 8GB RAM -- Plenty of memory for smooth multitasking and app switching.
  • 256GB or 512GB storage -- Choose the capacity that fits your needs. Larger options command a premium on the used market.
  • 4700mAh battery -- Large battery with fast wired charging and Qi wireless charging.
  • Android 13 + One UI 5.1 -- 4 years of OS updates + 5 years security. Samsung's long update commitment means this phone will receive software support for years to come.
  • IP68 water resistance -- Dust and water resistant (up to 1.5 meters for 30 minutes).
  • Samsung DeX -- Connect to a monitor for a desktop-like experience.

Who Is This Phone For?

  • Big-screen enthusiasts -- The Galaxy S23+'s large display is ideal for media consumption, gaming, and multitasking.
  • All-day battery users -- With a 4700mAh battery, the Plus model comfortably lasts a full day even under heavy use.
  • Budget-conscious buyers who want a large flagship -- Used prices make the Plus model significantly more affordable than buying new. As a two-generation-old model, used prices are especially attractive.
  • Upgraders from older Samsung phones -- If you're coming from an S21 or older, the improvements in display, camera, and performance are substantial.

Smart Tips for Buying Used

  • Check Google FRP lock -- A phone with Factory Reset Protection still tied to someone else's Google account is unusable. Make sure the seller confirms FRP is cleared.
  • Verify Samsung Knox status -- Knox 0x1 means the phone was rooted or modified at some point. This permanently voids Samsung warranty and disables Samsung Pay, Samsung Health, and some enterprise features. Knox 0x0 is what you want.
  • Check IMEI status -- Should be clean (not blacklisted or reported lost/stolen). You can check this for free at imeipro.info or similar services.
  • Screen burn-in -- AMOLED displays can develop burn-in over time, especially around the navigation bar and status bar areas. Ask the seller about any ghosting or permanent marks on the display.
  • Battery health -- Samsung doesn't show battery health percentage as easily as iPhones. Check Samsung Members app data if the seller can provide it, or look at battery cycle count. On a two-generation-old device, some battery degradation is normal.
  • Network lock -- Unlocked phones work on any carrier and command a premium. Carrier-locked phones are cheaper but restricted to one network.
  • Look for returns and warranty -- 30-day returns at minimum. Some professional sellers offer 90-day or 1-year warranties. All units are past Samsung's original warranty -- seller warranty matters more.
  • Trust the AI rankings -- Our system analyzes price, condition, seller trust, and return policies to surface the best deals. The top picks represent genuine value.

Frequently Asked Questions

Is the Samsung Galaxy S23+ worth buying used?

Yes. Every unit has the same Snapdragon 8 Gen 2 processor, the same camera system, and the same 6.6" FHD+ Dynamic AMOLED 2X 120Hz display -- there's no performance lottery. The only variable is storage size (256GB or 512GB). Buying used saves significantly off the original retail price. As a two-generation-old model, used prices are especially attractive -- you get a Samsung flagship with 50MP camera and 120Hz display for a fraction of the current retail price.

How does used compare to refurbished?

  • Used: Sold by the previous owner. Condition varies -- check the listing carefully for cosmetic wear, screen burn-in, and battery health.
  • Refurbished: Professionally inspected, tested, and cleaned by a seller or authorized refurbisher. Often comes with a warranty and graded condition (Excellent, Very Good, Good).

Both can be great value. Our AI evaluates condition, seller trust, and return policies regardless of the label.

What should I check before buying a used Galaxy S23+?

  • Google FRP lock -- Make sure Factory Reset Protection is cleared. A phone still tied to someone else's Google account is unusable.
  • Samsung Knox status -- Knox 0x0 is good. Knox 0x1 means the phone was rooted/modified, which disables Samsung Pay and voids warranty.
  • IMEI status -- Should be clean (not blacklisted).
  • Screen burn-in -- Look for ghosting or permanent marks on the AMOLED display, especially around the navigation bar.
  • Battery health -- Check the Samsung Members app data if available. Some degradation is normal for a two-generation-old device.
  • Network lock -- Unlocked phones work on any carrier. Carrier-locked phones are cheaper but limited.
  • Return policy -- At least 30 days. Many top sellers offer longer.

What's the difference between the Galaxy S23+ and the Galaxy S23 / S23 Ultra?

The Galaxy S23+ sits between the standard S23 and the S23 Ultra. Compared to the base S23, the Plus has a larger 6.6" display (vs 6.2"), a bigger 4700mAh battery, and QHD+ resolution. Compared to the Ultra, the Plus lacks the S Pen, the 200MP/108MP main camera, and the titanium frame -- but it's lighter and more affordable. For most people who want a big screen without the Ultra price premium, the Plus is the sweet spot.

What's the difference between 256GB vs 512GB?

Storage is the only hardware difference between units:

  • 256GB -- The base and most common option. Fine for most users.
  • 512GB -- Good for heavy photo/video shooters or large app libraries.

Our AI factors storage into the value ranking, so higher-storage deals that represent good value will rank accordingly.

Why are prices so different for the same phone?

Pricing varies by storage tier (256GB vs 512GB), network lock status (unlocked costs more), cosmetic condition, screen burn-in presence, battery health, and seller reputation. Our AI analyzes all of these daily to surface the best-value deals.
