The OnePlus 15R lists a larger screen, a higher maximum refresh rate, and a larger-capacity battery; the Samsung Galaxy S25+ lists a sharper display, a three-camera rear system with 3× optical zoom, and a smaller, lighter body. Those are manufacturer specification differences, not proof of which phone performs better in everyday use. A reliable current price difference cannot be stated without choosing a country, storage tier, seller, and date.
Samsung Galaxy S25+ vs OnePlus 15R: specs compared
The figures below come from OnePlus’s US specification page and Samsung’s Canada specification page. Regional configurations, accessories, and specifications may differ, so confirm the version sold in your market before buying.

Which display suits your priorities?
OnePlus 15R: larger panel and higher listed refresh ceiling
The 15R has the larger display and lists adaptive refresh rates up to 165 Hz. That upper mode is not universal: OnePlus limits 144 Hz and 165 Hz to listed apps. If you care about high refresh rates for gaming or other supported apps, check that your specific apps can use those modes rather than assuming the whole interface runs at 165 Hz.

Galaxy S25+: more pixels in a slightly smaller display
Samsung lists a 3120 × 1440 resolution on its 6.7-inch screen, compared with the 15R’s 2800 × 1272 on 6.83 inches. The S25+ therefore has the higher listed resolution, while the 15R offers more screen area and a higher maximum refresh rate. These figures alone do not establish overall display quality, which also depends on factors not compared here.

Camera hardware: optical zoom is the clearest distinction
Samsung lists three rear cameras and 3× optical zoom. OnePlus lists a 50 MP main camera and an 8 MP ultra-wide camera in the retrieved specifications. That makes the S25+ the one with a specifically listed optical-zoom capability in this comparison; it does not establish which phone takes better photos. Megapixel counts are not a substitute for image-quality testing.
The listed front-camera resolutions are 32 MP for the OnePlus 15R and 12 MP for the S25+. Treat that as a resolution comparison, not a verdict on selfie quality.
Rank #2
- 6.7‑inch Dynamic AMOLED 2X QHD+ display (3120 × 1440) with adaptive 1‑120 Hz refresh rate, HDR support, and up to ~2600 nits peak brightness — providing a large, sharp, and very bright screen.
Battery capacity and charging: what the numbers do—and don’t—show
OnePlus lists a 7,400 mAh typical capacity and a 7,250 mAh rated capacity for the 15R. Samsung lists 4,900 mAh typical capacity for the S25+ and up to 30 hours of video playback. Capacity favors the 15R on paper, but battery capacity by itself cannot establish which phone lasts longer in real-world use; usage, display settings, software, and other conditions matter.
For charging, OnePlus’s US specification page lists 55 W SUPERVOOC and separately mentions up to 80 W with a named OnePlus adapter. The retrieved Samsung Canada passage does not establish a charging speed. These figures do not establish charging time or what adapter is included in a particular regional package.
Rank #3
- 6.7‑inch Dynamic AMOLED 2X QHD+ display (3120 × 1440) with adaptive 1‑120 Hz refresh rate, HDR support, and up to ~2600 nits peak brightness — providing a large, sharp, and very bright screen.
Size and weight: the S25+ is the more compact option
By the manufacturers’ listed measurements, the Galaxy S25+ is shorter, narrower, thinner, and lighter. It is listed at 190 g, while the OnePlus 15R is listed at 214 g or 215 g depending on color. The 15R’s larger display comes with a larger, heavier handset; whether that trade-off matters depends on how you hold or carry your phone.
Price difference: why there is no dependable single figure
The available price information does not establish a current, like-for-like price pair for these two phones in one market. The secondary comparison mixes currencies and models, and the retrieved official OnePlus US pricing page is for the OnePlus 15, not the 15R. It would therefore be misleading to give a single current price gap from those figures.
Rank #4
- 6.7‑inch Dynamic AMOLED 2X QHD+ display (3120 × 1440) with adaptive 1‑120 Hz refresh rate, HDR support, and up to ~2600 nits peak brightness — providing a large, sharp, and very bright screen.
For a meaningful comparison, use prices from the same country and date, and match the storage tier, seller type, and unlocked or carrier status. If you also want to compare launch pricing with today’s deals, keep those separate: a launch MSRP and a current sale price answer different questions.

- Consider the OnePlus 15R if a larger screen, high listed refresh rates in supported apps, or higher stated battery capacity is central to your choice. These are specification-based considerations, not measured performance or endurance results.
- Consider the Galaxy S25+ if you prefer a higher-resolution listed display, a dedicated 3× optical-zoom capability, or the smaller and lighter dimensions in the manufacturer specifications.
- Compare regional listings before deciding if price, storage, charging accessories, or software details are decisive. The available specifications do not provide a complete same-region, same-storage comparison for every item.
Software support and regional details
Samsung’s retrieved Canada specification page lists a security-update period through 31 January 2032. The OnePlus US specifications cited here do not establish a comparable software-support period, so the available information is not enough to compare support duration. Check the support terms that apply to the exact regional model before treating this as a deciding factor.
