Samsung Galaxy S25 Ultra Long-Term Review: What Holds Up Over Time?

② In Depth: What Holds Up Over Time

Analysis based on Samsung’s published specifications, published fees and coverage terms, plus dated third-party coverage — each figure labelled by origin.

The warranty line has already crossed: launch buyers are out, new buyers are in

Every Galaxy S25 Ultra carries Samsung’s standard 1-year limited warranty, but the warranty runs one year from each buyer’s own purchase date — so the line has already crossed for the launch cohort. A phone bought when US sales began on 7 February 2025 left its warranty year around February 2026, roughly eight months before this review. A new unit bought now carries its own 1-year warranty from its purchase date. That split is the single most important long-term fact about this model, and it is also the easiest to get wrong: never claim the model as a whole is still inside its warranty year, and never claim it as a whole is out of warranty either. For owners, the practical consequence is that a defect claim now runs through the purchase date on the receipt, not through the launch date. For used buyers, the practical consequence is that remaining warranty is a question to verify with Samsung, not an assumption to make from the model name. Samsung’s warranty covers defects, not accidental or liquid damage — accidental damage is precisely what Care+ exists to cover — and the IP68 rating travels with its caveats (lab conditions, 1.5 m fresh water / 30 minutes, not permanent, liquid damage not warranty-covered). A repaired or cracked phone does not keep the lab rating in practice, and twenty months of daily use is exactly when that caveat starts to matter.

No list-price change in twenty months — and what that means for used prices

The US list prices have not moved since launch: $1,299.99 for 256GB, $1,419.99 for 512GB and $1,659.99 for 1TB, re-checked 5 November 2026. The October 2026 list-price rise that lifted the S26 Ultra does not apply here, and no rise story should be attached to this model. That stability cuts two ways for long-term value. On the new side, the phone is the previous-generation Ultra at its original list, which makes the newer Ultra’s higher list the comparison that matters — a buyer choosing between them is choosing between a titanium previous generation at $1,299.99 and an Armor Aluminum newer generation at a higher list. On the used side, the stable new price is the anchor against which any used price should be judged: check current listings for the exact tier and condition before paying, verify the tier on the device, and remember that a used unit carries the expired-launch-warranty framing while a new unit does not. No used or refurbished price is printed in this review, because no dated used-market check was recorded for this article.

Care+: the window launch buyers are now outside, and the diagnostic that matters later

Samsung Care+ enrolment is time-boxed: eligible pricing at purchase or within 60 days, with purchase possible within 1 year at different pricing after day 60. For a launch buyer, that one-year window closed around February 2026 — the same month the standard warranty expired — so enrolment at eligible pricing is no longer open to the launch cohort. A later buyer is on their own clock, measured from their own purchase date. For owners who are enrolled, the terms that matter over time are the claim fees ($29 screen / $29 back glass on standard Care+; $0 / $0 with Theft and Loss; lost/stolen deductible is the $99–$199 range only) and the battery rule: battery repairs are included subject to a diagnostics test confirming 79% or less battery capacity. That diagnostic is the long-term battery number that actually exists for this model — Samsung publishes no per-model Care+ monthly price, and no per-model lost/stolen deductible point inside the $99–$199 range, so neither is printed here as a Samsung-published fact.

Materials and design: what twenty months can and cannot tell you

The materials story is unchanged, because it is a specification story, not a wear story: a titanium frame (Samsung’s own wording, footnoted to the frame excluding the volume and side keys), a Corning Gorilla Armor 2 front, and a Corning Gorilla Glass Victus 2 back (attributed to spec databases and launch spec tables). The rear cameras are individual lenses on the back panel — there is no raised “camera island” housing story on this model. What twenty months cannot tell this review is how any individual phone has worn, because FixUpPhone did not carry one: no drop result, no scratch result and no “still looks new” claim appears here. What can be said is structural: the S Pen is a passive stylus with no Bluetooth, no charging and no Air Actions, so there is no pen battery to degrade and no wireless pen feature to lose — the removal that happened on this model is, in long-term terms, one fewer thing to fail — while Air Command, which needs no Bluetooth, remains. The display is a 6.9-inch Dynamic AMOLED 2X panel at QHD+ with 1–120Hz adaptive refresh, a 2,600-nit peak (manufacturer specification) and ProScaler; there is no Privacy Display on this model, so a screen replacement is never a Privacy Display replacement.

Battery and repairability: the two long-term numbers that are actually published

The battery is the same 5,000 mAh typical / 4,855 mAh rated cell as at launch, and Samsung’s only published usage figure is still video playback up to 31 hours — no audio-playback, typical-use or talk-time figure exists, and no new usage figure has been published since launch. The EU energy label’s figures are regulatory context only: 2,000-cycle / 80% capacity retention, 44:54h standardised endurance, Class B energy / Class A free-fall / Class C repairability — never Samsung usage claims, and never the S26 line’s 1,200-cycle figure. Charging is unchanged too: 45W wired with Super Fast Charging 2.0 and “up to 65% in around 30 minutes” as the only charge-time claim, 15W wireless, 4.5W reverse, Qi2 Ready with no built-in magnets claimed. As attributed third-party evidence, GSMArena’s February 2025 review measured modest but not insignificant improvements over the previous generation in its gaming test and in video playback, with web browsing and voice call time remaining essentially the same — a launch-window measurement, not a twenty-month measurement, and labelled as such. On repairability, iFixit’s teardown coverage gives this model a provisional 5 out of 10 repairability score and calls it the most repairable Galaxy phone in years — a third-party assessment, not a Samsung figure — praising the battery’s four pull tabs, which release without heat or solvents, and the modular camera array, while criticising the adhesive that secures the display and back glass. For a phone now out of warranty for its launch buyers, that repairability story is the long-term fact that matters most: the battery is the part most likely to need replacing first, and it is the part Samsung made easier to remove.

Questions to ask before you buy used, or keep what you have

Ask the seller for the storage tier and verify it on the device, and confirm the checkout price against the unchanged list. Ask when the unit was bought, and verify the remaining warranty and any active Care+ plan with Samsung — launch buyers are out of warranty, so a used unit’s cover is a question, not an assumption. Ask whether the battery has ever been replaced, and whether the unit shows any swelling or heat: a swollen or hot battery is a safety matter, not a cosmetic one, and a hot or swollen phone should never be mailed. Ask what charger is included, because Samsung’s 65%-in-around-30-minutes claim is a 45W wired claim. And if you already own the phone, the keeping question is a battery question first and a camera question second: price a battery diagnosis before any upgrade, because Samsung publishes no static battery price and the quote — or the Care+ ≤79% diagnostic route — is the number that matters.
