Detailed Comparison
Design & Build
OnePlus 15T
OnePlus inherits the design language of the OnePlus 15 — metal frame, glass back, micro-arc oxidation finish on the rails — and shrinks it into a 6.32-inch, 194g body that's roughly iPhone 17-sized but with more than twice the battery capacity. IP66/IP68/IP69/IP69K rating, ultrasonic fingerprint sensor and ~1.1mm symmetric bezels are unambiguous flagship moves. Reviewers debate whether 6.32-inch genuinely counts as compact in 2026.
Same premium design as the OnePlus 15 — metal frame, glass back, IP69 water resistance — feels high-quality in the hand at just 194g.
Dimensions and weight are similar to an iPhone 17, but the 15T packs more than twice the battery capacity with a ~91% screen-to-body ratio.
Full-level water resistance and a fast ultrasonic fingerprint sensor make the 15T noticeably more confident outdoors than the OnePlus 13T was.
The metal frame uses a micro-arc oxidation process with a 50/50 weight distribution — it doesn't feel top-heavy and one-handed use is genuinely comfortable.

The new 3.5x periscope telephoto with OIS is a meaningful step up from the OnePlus 13T's limited 2x zoom and is well-suited to portraits at the classic 85 mm focal length.
Deal Breakers
China-only launch with no confirmed global release — ColorOS instead of OxygenOS, no eSIM support, no WearOS support, and missing European LTE band 20 and band 32 make it a compromise outside China.
Notebookcheck measured pronounced sustained-performance throttling of over 50% in 3DMark stress tests, with surface temperatures climbing past 46 °C; SuperSaf hit 50 °C on the back during Wildlife Extreme and saw scores drop from 6,990 to 3,743 inside a single loop.
No ultrawide camera at all — the 'triple camera' is just main + 16MP front + 3.5x periscope telephoto, which is a downgrade versus the OnePlus 15 for anyone who shoots landscapes, group photos or wide-angle video.
Charging port is still USB 2.0 in 2026, which SuperSaf calls 'a choice and not a good one' on a flagship-tier device at this price.
No built-in MagSafe-style magnets — wireless-charging accessories require a separate magnetic case to align properly.
Software-support window is uncertain: OnePlus has not committed to a specific update timeline for the Chinese-market 15T, and the global OnePlus 15 already commits to only 4 years of major Android upgrades — well behind Samsung and Google's 7-year promises.
Samsung Galaxy S25 Edge
What Reviewers Agree On
At 5.8mm and 163 grams the Edge genuinely feels transformatively lighter and thinner in hand than any other current flagship — picking it up is repeatedly described as a surprise even by reviewers skeptical of thin phones.
Build quality is premium and durable for the form factor — titanium frame, Gorilla Glass Ceramic 2 on the front (first phone to use it), Gorilla Glass Victus 2 on the back, IP68 rating intact.
The 6.7-inch 1440p LTPO AMOLED is one of the best smartphone displays in 2025 — 2,600-nit peak brightness, 120Hz, sharp and bright in any lighting.
Short-burst performance from the Snapdragon 8 Elite for Galaxy + 12GB RAM matches or beats the S25 Ultra in single-shot benchmarks, with no noticeable lag in everyday use.
The 200MP main sensor (inherited from the S25 Ultra) takes genuinely strong photos with crisp detail, and the new wider 12MP selfie camera is a small upgrade for group shots.
Samsung commits seven years of OS and security updates, matching the industry's best long-term support window.
Deal Breakers
The 3,900 mAh battery is the smallest in the entire Galaxy S25 lineup — smaller even than the base S25's cell — and real-world endurance trails the S25+, S25 Ultra and most rivals by a meaningful margin.
There is no telephoto camera at all — only the 200MP main and a 12MP ultrawide — making it the only S25 phone without optical zoom and a hard sell for anyone who shoots distant subjects.
Under sustained 3DMark stress tests Notebookcheck measured GPU performance dropping to roughly half its initial score (46.3% Wild Life stability), confirming the slim chassis can't dissipate enough heat for long gaming sessions.
Wired charging is capped at 25W and wireless at 15W — well behind the OnePlus 13 and Xiaomi rivals, with a full charge taking about 1 hour 20 minutes from the wall.
Samsung skipped the new silicon-carbon battery chemistry already shipping in the OnePlus 13, Xiaomi 15, Vivo X200 and other competitors — the single technology that could have made the thin form factor work, repeatedly flagged by MKBHD, Dave2D and Mrwhosetheboss.

The pure cocoa colorway is OnePlus's first-ever brown finish and stands out next to the standard 15's black/violet/sandstorm options.
Calling a 6.32-inch phone 'compact' just normalizes the new baseline — at this size the only thing keeping it small is OnePlus refusing to make the body any larger, not any genuine effort to shrink the footprint.
r/gadgets commenters reject the compact framing outright — '6.3" screen is NOT compact' is the top reply on the official-first-look thread, with multiple users asking for a true 5.x-inch option.
Samsung Galaxy S25 Edge
At 5.8mm and 163 grams the S25 Edge is the thinnest and lightest Galaxy flagship ever, and nearly every reviewer concedes that picking it up changes their opinion of thin phones — even those who came in skeptical. The frame is grade-5 titanium with Gorilla Glass Ceramic 2 (a smartphone first) on the front and Victus 2 on the back, IP68 rating preserved. The camera bump protrudes enough that the phone wobbles noticeably on a flat surface, and several reviewers point out a case immediately negates the thin-phone benefit.
After living with the Edge for two weeks, the lighter weight repeatedly tricked the reviewer into thinking she'd left her phone at home — the slimmer dimensions make a tangible difference in pockets and small bags the way no other modern big phone does.
At 5.8mm it is 2mm thinner than the iPhone 16 Plus and weighs 36 grams less despite the same 6.7-inch screen — picking it up genuinely feels strange and, surprisingly, not cheap.
Samsung kept the titanium frame and IP68 rating, and the Gorilla Glass Ceramic 2 panel is a smartphone first — the Edge is undeniably enchanting in sheer feel and aesthetics.
The titanium frame meets the glass at a minutely chamfered edge that banishes the sharp digging-into-the-palm sensation of the S25 Ultra — for an hour straight it never once felt fatiguing.
The Edge ruined the reviewer's previously positive experience with the S25 Ultra in 24 hours — the Ultra suddenly feels thick and noticeably heavy by comparison.
Even on video of his own hands holding it the difference looks subtle, but it is very noticeably thinner to hold — the kind of feel-it-to-believe-it engineering you don't get from a spec sheet.
Picking up the Edge was very reminiscent of his first time picking up a MacBook Air or a new iPad — 30% thinner and 25% lighter doesn't sound transformative on paper but absolutely feels it.
Just under 4mm thick, the camera bump on the back is quite prominent — including the lenses the Edge is almost as thick as the S25+, and on a table it wobbles back and forth considerably.
The phone rocks a lot on a table due to the camera bump and even with a case the Edge won't stop wobbling because case-makers want to preserve as much thinness as possible.
Display
OnePlus 15T
The 6.32-inch 165 Hz 1.5K AMOLED panel is the only true 165 Hz compact-flagship display on the market and pairs that refresh rate with a measured 1,800 nits brightness, 460 ppi pixel density, Crystal Shield Glass, and HDR10+/Dolby Vision support. Native 165 Hz support in popular FPS games is a real differentiator. Notebookcheck flags 120.7 Hz PWM dimming that can cause eyestrain for sensitive users.
The 6.32-inch 165 Hz AMOLED panel achieves a very good 460 ppi pixel density and the advertised maximum brightness of 1,800 nits in standard measurement.
Display sharpness is plenty competent — sharp, smooth, and easily one of the strongest spec sheets you can get on a compact phone.
Native 165 Hz support in COD, Delta Force and Peacekeeper Elite makes this the only small-screen flagship pushing a full 165 Hz gaming experience.
OnePlus claims up to 3,600 nits peak brightness — even on a playground in direct sunlight you can still see everything clearly, no squinting required.
Specifications confirm a 6.32-inch 1.5K (1216 × 2640) resolution with 165 Hz refresh — a configuration unique to the 15T in the compact class.
Display backlight flickers at just 120.7 Hz under PWM dimming — low enough that the flickering may cause eyestrain and headaches for sensitive users after extended use.
Samsung Galaxy S25 Edge
The 6.7-inch QHD+ LTPO AMOLED is essentially the same panel as the S25+ — 120Hz, sharp, very bright. Samsung says it skipped the S25 Ultra's anti-reflective Gorilla Armor 2 coating because the coating itself would have added thickness, so the Edge gets the glossier finish back. PWM dimming only reaches 480Hz which Notebookcheck flags as a potential issue for sensitive eyes.
The 6.7-inch panel is just as vibrant and wonderfully colourful as the S25+ — same OLED, same 120Hz refresh rate, no compromise on screen quality.
With auto-brightness enabled the panel exceeded 2,600 nits in HDR content and regularly cleared 1,000 nits, with even the manual SDR brightness boost hitting 700–800 nits in real testing.
Slimmer bezels on an absolutely gorgeous display make the Edge feel like holding a portal — and the 2,600 nit peak brightness is right in line with the S25 Ultra's spec.
The display is also fantastic, and the QHD+ AMOLED is one of the highlights of using the phone — battery aside, the screen alone makes the Edge a treat.
Samsung skipped the Ultra's anti-reflective coating because — and this is on the record — Samsung says the coating itself would have increased the phone's thickness.
Camera
OnePlus 15T
OnePlus has dropped the Hasselblad partnership (now Oppo-exclusive) and built the 15T camera around two 50MP sensors — a main with a 1/1.56-inch Sony IMX906 and OIS, plus a new 3.5x periscope telephoto with OIS at the classic 85mm portrait focal length. There is no ultrawide. Notebookcheck still rates the system 'a class above' the iPhone 17, but reviewers agree this is the area where the 15T's compact-and-cheap positioning is most visible — sensor sizes are small, sharpness and dynamic range trail genuine top-tier flagships, and the OnePlus 15 / Oppo Find X9 Pro siblings keep the better imaging.
The new 3.5x periscope telephoto delivers a classic 85 mm focal length perfect for portraits — a huge step forward from the OnePlus 13T's limited 2x zoom.
OnePlus has confirmed the headline upgrade is a LUMO periscope telephoto with both improved hardware and improved algorithms, focused on stronger zoom and better atmospheric portraits.
Despite the small 1/1.56-inch main sensor, the 15T's daylight and low-light photos are 'still a class above' the iPhone 17 in side-by-side comparison.
The 50MP main sensor lacks sharpness and dynamics — good photos are possible in both daylight and dark, but top quality looks different.
There is no ultra-wide-angle camera at all — the omission is partly excused by the new periscope, but it's a meaningful downgrade versus the OnePlus 15's triple-camera system.
The telephoto produces unstable results inconsistent with the main sensor — at night the camera struggles with depth perception and doesn't always switch to the periscope when it should.
The cooperation with Hasselblad is now Oppo-exclusive, and the OnePlus 15T's built-in image sensors are quite small and therefore not very bright.
The selfie camera drops from 32MP on the OnePlus 15 to 16MP on the 15T — a small but real downgrade for anyone who shoots a lot of front-facing video.
Samsung Galaxy S25 Edge
Two cameras only — the 200MP main from the S25 Ultra (slightly flattened to fit the chassis) and a 12MP ultrawide. There is no telephoto lens, optical zoom is gone, and the 2x and beyond are pure digital crops from the 200MP sensor. The Verge and Engadget defend the trade and say the high-res crop works at 2x; Wired, Digital Trends and GSMArena call missing zoom the camera's biggest disqualifier on a $1,099 phone.
The Edge inherits the same top-of-the-line 200MP main camera that previously only the Ultra phones got — a real win for image quality on a non-Ultra Galaxy.
Samsung included a top-shelf 200MP main camera to make up for the missing telephoto, and the 2x crop zoom works fine for a little extra reach — colors are punchy as always.
Despite the slim body the Edge still uses a large 1/1.3-inch sensor on the main camera and a 12MP ultrawide — pictures up to 2x crop are sharp and image quality is solid in good light.
There is no telephoto zoom camera at all — rare for a $1,000-plus phone today, and zoom quality deteriorates quickly past 2x digital, making this an uncomfortable choice for anyone who shoots distance.
Battery & Charging
OnePlus 15T
This is the section the OnePlus 15T was built to win. The 7,500 mAh silicon-carbon 'Glacier' cell is the largest ever fitted to a true compact phone — 50% bigger than the iPhone 17's pack in a similar footprint. Notebookcheck measured roughly 1.5 days of real-world endurance at 150 cd/m². Wired charging tops out at 100 W, wireless at 50 W. The only friction points are the missing built-in magnets for MagSafe-style alignment and the still-USB-2.0 port.
OnePlus relies on a silicon-carbon-based battery with a large capacity of 7,500 mAh for its mini flagship — in our practical battery test at 150 cd/m² brightness, the 15T achieved an excellent battery life of nearly 1.5 days.
9to5Google's preview confirms the 7,500 mAh cell carries the same 'Glacier' moniker as the OnePlus 15's battery, so the silicon-carbon structure is here too — 200 mAh more than the larger sibling.
Even though the phone keeps the same compact size, it now packs a massive 7,500 mAh battery — to put that into perspective, the iPhone 17 Pro Max only has around 5,000 mAh, and this is a 6.32-inch phone.
Battery life is wild for a phone this size and is actually a hair bigger than the one in the OnePlus 15, which has a noticeably larger footprint.
100W SuperVOOC wired charging and 50W wireless mean even the huge cell refills fast — getting through two full days on a single charge feels totally realistic.
There is no native magnetic Qi alignment — wireless charging works, but accessories require a separate magnetic case for MagSafe-style snap-on functionality.
r/Android's reaction to the battery is unambiguous — 'Incredible battery life makes the compact smartphone competition pale in comparison' is the actual review-thread headline.
Samsung Galaxy S25 Edge
The 3,900 mAh cell is the smallest in the entire S25 family — even smaller than the base S25's 4,000 mAh battery. Engadget's local video rundown clocked 25 hours 59 minutes (about 3.5 hours less than the Ultra and two hours less than the standard S25); Notebookcheck reached almost 18 hours of simulated web browsing. Real-world experience is split: The Verge survived a heavy Google I/O day with 20% left; Wired needed mid-day top-ups; Trusted Reviews hit 5% by midday after only two hours of screen-on time. Wired charging caps at 25W. The single most-flagged complaint is Samsung's decision not to use silicon-carbon battery tech that competitors already ship.
A full day covering Google I/O with three hours of screen time and an hour-ish of hotspot use ended with 20 percent left — not amazing, but fine for a heavy use day if you can plug in by evening.
Engadget's local video rundown lasted 25 hours 59 minutes — about three and a half hours less than the S25 Ultra and two hours less than the base S25.
Almost 18 hours of simulated web browsing and over 25 hours of HD video playback in lab testing — sufficient for a day of intensive use even if it doesn't quite beat similarly priced rivals.
Software & AI
OnePlus 15T
The OnePlus 15T ships with ColorOS 16 on Android 16 in China rather than the global OxygenOS, though the two skins are now nearly identical in feel. Update commitments are unclear — OnePlus doesn't publish a timeline for Chinese-market hardware, and even the global OnePlus 15 only commits to 4 years of major Android upgrades. Mind Space (AI-powered productivity vault) and Gemini integration are the headline software features.
ColorOS 16 comes pre-installed on the 15T instead of OxygenOS — but the differences are minor overall, with German language and Android Auto supported, though no WearOS watches or eSIMs.
There are question marks over the duration of the updates provided — the manufacturer does not usually provide any information on this for China, though typically a OnePlus 15-class phone should receive security updates for six years.
OxygenOS 16 (and ColorOS 16 by extension) integrates Gemini with Mind Space — you can ask Gemini about any saved memory and it accesses local content to perform tasks, making it the best on-phone AI integration we have seen.
Mind Space is the headline AI feature — a digital vault that takes a screenshot of important content and saves it as a card with URL, summary, title and hashtags for contextual search.
The system feels incredibly smooth — arguably one of the best experiences you can get on Android right now, with useful features for students like meeting summaries and lecture transcription.
Update commitment trails the competition — even on the global OnePlus 15 the company only promises 4 years of major Android upgrades, well behind Samsung and Google's 7-year commitments.
Samsung Galaxy S25 Edge
Same One UI 7 on Android 15 as the rest of the S25 lineup, same Galaxy AI feature suite (Now Brief, generative photo editing, Gemini integration), same seven-year OS and security update commitment. No platform differentiator over the cheaper S25 or S25+ — software is identical, so the Edge's pitch lives entirely on hardware design.
Same One UI 7 on Android 15 as the rest of the S25 lineup, with the full Galaxy AI feature set including Now Brief, generative editing and Gemini as the default assistant.
Seven years of major Android upgrades and monthly security patches until 2031 — matches the best long-term support in the industry.
Very pleasing and fluid One UI experience, DeX support, seven major OS updates — listed as a pro across the verdict even by reviewers cool on the hardware.
Shout-out to the realtime visual Gemini Live feature — you can be on a video call with the AI and point at an object and have it answer contextual questions, real-world impressive AI even if execution isn't perfect.
Selfie camera supports log video recording — a small but real software differentiator the rest of the S25 series doesn't currently have.
At $1,099 the Edge sits between the cheaper S25+ ($999) and the only-$100-more S25 Ultra ($1,299), and reviewers across The Verge, Wired, GSMArena and Ars Technica agree neither end of that bracket is a comfortable place to land given what you give up.
Wireless charging works through a 'Qi2 Ready' label rather than built-in magnets — you need a separate magnetic case for MagSafe-style accessories, the same issue Engadget called out on the S25 Ultra.
There is no S Pen support and no S Pen slot — the Ultra's signature feature is gone, removing the one reason you'd traditionally pay over $1,000 for a Samsung flagship without compromise.

The Ultra's anti-reflective glass is missing on the Edge — losing that anti-glare property is genuinely a downgrade if you've used the S25 Ultra outdoors.
The AMOLED flickers at a comparatively low 240Hz at minimum brightness rising to 480Hz at higher levels, and the amplitude isn't particularly flat — PWM-sensitive viewers may notice eye strain.
Missing telephoto is a serious downside even mid-range phones now include — the Edge is essentially banking on its thinness to drag buyers away from rivals that all have one.
The Edge lacks a telephoto camera and low-light photography is suboptimal — listed as a con in the final verdict despite the 200MP headline number.
Samsung flattened the main camera lens structure to keep the phone slim, which makes the output slightly softer than the S25 Ultra — the same shot taken multiple times consistently came out a touch less sharp.
Coming from the S25 Ultra he genuinely missed the periscope zoom while travelling at Computex — for trip photography the missing telephoto is a real loss.
After only four hours of screen-on time the phone hit 15% — only light-to-average use will get you a full day, and travelling I/O coverage required mid-afternoon charging anxiety.
Off a full charge at 3pm, the phone hit 30% by morning and 5% by midday with only two hours of total screen time — Trusted Reviews calls this 'the phone that reintroduces battery anxiety' for the modern era.
Wired charging tops out at 25W and a full charge takes 1 hour 20 minutes — pedestrian numbers for a smartphone in this price category.
The Edge sticks with regular lithium-ion battery tech, not the silicon-carbon anode chemistry rivals like the OnePlus 13, Xiaomi 15, Vivo X200 and several Honor phones already ship — a 15–20% battery boost left on the table.
Skipping silicon-carbon was 'a big miss' — if Samsung had used it, the same thin chassis could have held meaningfully more capacity and the battery debate would have evaporated.
If this were a more energy-dense silicon-carbon battery the conversation would be entirely different — but it isn't, and within a few years as the cell degrades buyers may regret prioritising thinness over capacity.
Wireless charging is 'Qi2 Ready' rather than fully Qi2 compatible — there are no magnets inside the phone, so MagSafe-style accessories require a separate magnetic case or adhesive ring.
