At 5.64mm thick and 165g the iPhone Air's hand-feel is the most genuinely new thing about any 2025 iPhone — almost every reviewer says you have to hold it to understand why people pay the premium.
The titanium grade-5 frame plus Ceramic Shield 2 makes it the most durable iPhone yet, surviving 130-pound Apple bend tests and JerryRig-style torture without bending or cracking.
The 6.5-inch ProMotion OLED with 3,000-nit peak brightness, anti-reflective coating and always-on display is identical in quality to the 17 Pro panel and gets praised across the board.
The A19 Pro chip with 12GB of RAM delivers Pro-tier performance in normal use — Geekbench multi-core lands around 9,600-9,800 and apps stay in memory noticeably longer than 8GB phones.
The new 18MP square Center Stage front camera is the year's standout iPhone feature — you can shoot landscape selfies while holding the phone vertically without rotating, and group shots auto-frame.

Detailed Comparison
Design & Build
iPhone 17 Air
The iPhone Air is the most physically distinctive new iPhone in years — 5.64mm thick (down from 7.95mm on the iPhone 17), 165g (12g lighter than the iPhone 17, 41g lighter than the 17 Pro), grade-5 titanium frame with polished mirror-finish sides, and a horizontal 'plateau' across the top that houses the A19 Pro, single camera and speakers because the rest of the body is occupied by the battery. Apple says it's the most durable iPhone ever (Ceramic Shield 2 front, Ceramic Shield back, 130-pound bend test) and so far real-world durability tests agree — no bendgate 2.0. The polish does come with one consistent caveat: it's slippery and feels precarious without a case, and the optional case partly defeats the thinness.
It's 5.64mm thick versus 7.95mm for the iPhone 17 — challenge anyone to pick it up without being surprised at how much lighter it feels.
Initially the lighter weight makes the Air seem 'cheap', but that notion quickly disappears — the phone feels strong, durable, and rigid thanks to the titanium frame.
Apple is setting new highs for mobile design with the iPhone Air — it's a 'sci-fi space pebble' that's a marvel of engineering you really have to hold to appreciate.

Battery life is better than the rumours suggested before launch — most reviewers can scrape through a normal day on the 3,149 mAh cell, though heavy travel days will need a top-up.
Deal Breakers
Single 48MP rear camera with no ultrawide, no telephoto and no macro is the most-cited compromise — even reviewers who like the phone admit they consistently miss the second lens, and Reddit owners flag it as the one regret six months in.
Mono speaker in the earpiece (no bottom speaker) sounds thin and bass-light for movies, music and podcasts — multiple reviewers and Reddit users call it the deal-breaker that ruled the phone out for them.
Battery life trails every other phone in the iPhone 17 lineup — 27h Apple video rating, 6h 43m in The Tech Chap's real-world battery test (12 minutes behind the iPhone 17, 76 minutes behind the 17 Pro Max), and heavy users hit 20% before dinner.
$999 price is widely flagged as the single biggest problem — for $200 less you get a more-versatile iPhone 17 (two cameras, stereo speakers, longer battery), and for only $100 more an iPhone 17 Pro with vapor chamber, three cameras and 4x/8x optical zoom.
USB-C port is limited to USB 2 (480 Mbps) data transfer speeds and there's no mmWave 5G support — odd corner-cuts on a $999 phone in 2025.
Aggressive thermal throttling under sustained GPU load — the lack of a vapor chamber means Genshin Impact and similar games measurably slow down within an hour, and the camera-bar plateau heats up noticeably.
OnePlus 15T
What Reviewers Agree On
The 7,500 mAh silicon-carbon 'Glacier' battery is unprecedented in a 6.32-inch body and delivers roughly 1.5 days of real-world endurance — easily the longest battery life in the compact-flagship class.
Build quality is genuine flagship-grade: metal frame, IP66/IP68/IP69/IP69K dust + water resistance, ultrasonic in-display fingerprint sensor, and a 91% screen-to-body ratio with ~1.1 mm symmetric bezels.
The 6.32-inch 165 Hz 1.5K AMOLED reaches the advertised 1,800 nits in standard measurement and is marketed up to 3,600 nits peak — making it the only true 165 Hz compact-flagship display on the market.
Snapdragon 8 Elite Gen 5 + 16GB LPDDR5X Ultra Pro RAM hits Geekbench multi-core ~10,976 and 3DMark Wild Life Unlimited ~29,901 — top-tier flagship synthetic performance in a sub-200g chassis.
100W wired SuperVOOC and 50W wireless charging mean even the giant battery refills fast.
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.

The iPhone Air is the radical redesign of the iPhone I have been wanting for years — perfectly balanced at 165g and the most fun I've had with an iPhone since the iPhone X.
Apple performed a bend test with 130 pounds of force and the iPhone Air showed no damage at all — Ceramic Shield 2 on the front and Ceramic Shield on the back make this the most durable iPhone yet.
The thinness is genuinely impressive, but the polished titanium edges are slippery — without a case I felt the phone could fly out of my hands, and it did once during testing.
The thin profile makes it harder to feel like you have a good grip on the phone, and holding it can feel precarious — adding a case helps but partly defeats the thin-and-light effect.
At 165g it's the lightest full-screen iPhone Apple has made, but it's still heavier than the iPhone 12 mini (135g) and 13 mini (141g) — so 'lightest ever' has caveats.
The frosted glass back resists fingerprints, isn't slippery once you adjust, and looks even better without a case — though it's still all-glass so AppleCare+ is recommended.
It's been five months and I still love the design — comfortable to pick up, hold, and use for long periods. Up there with the iPhone 7 and iPhone 12 mini as one of my favourite iPhones ever.
I'm disabled with a progressive illness and as my hands weaken, the Air has been a game changer — so light and easy for me to hold one-handed now.
The 'sexiest phone ever made' — I smile every time I pick mine up. It's the sexiest phone ever made.
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 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.
Display
iPhone 17 Air
The 6.5-inch LTPO Super Retina XDR OLED is identical in spec to the iPhone 17 Pro Max panel — same 1-120Hz ProMotion, same 3,000-nit peak brightness, same anti-reflective coating, same Dolby Vision HDR support, same always-on display. It sits exactly between the 6.3-inch iPhone 17 and the 6.9-inch iPhone 17 Pro Max in size, which most reviewers consider the sweet spot for a one-handable big-screen phone. The Dynamic Island sits slightly lower on the Air to accommodate the camera plateau, and a few apps haven't adapted, but the visual quality itself is universally praised. No reviewer found a real complaint with the display.
The 6.5-inch OLED screen feels improbable in this thin and light design — bright enough to read in direct sunlight, with a 120Hz refresh rate that finally brings the regular iPhone family up to Android-standard smoothness.
Peak brightness is 3,000 nits with ProMotion 1-120Hz, and putting a display this good in a body this thin sometimes really does look like a magazine page floating in your hand.
The iPhone Air screen is glorious — there's not much separating it from the Pro models in screen terms. Both hit 3,000 nits peak and 1 nit minimum, fantastic in bright and dark conditions.
I have no complaints about the Super Retina XDR display — great viewing angles, the new anti-glare coating actually reduces reflections, and it's as good as a phone screen gets.
A 6.5-inch screen is the perfect Goldilocks size — big enough to watch Netflix comfortably on the train, but small enough to use in one hand, something I couldn't do with the 6.9-inch Pro Max.
After a year on the 6.3-inch iPhone 16 Pro, holding the Air's 6.5-inch panel in a 5.6mm chassis feels like holding the future.
The screen is wider and taller than the 6.3-inch phones, but a little of that size is wasted on the no-man's-land above the Dynamic Island, which iOS apps can't really use.
In GSMArena's lab the panel hit 998 nits in auto mode and 780 nits in manual mode, with exceptional sunlight legibility in real-world use.
The Dynamic Island sits slightly lower on the iPhone Air to accommodate the camera plateau, and some notifications expanding from it haven't been updated to accommodate that change.
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.
Performance
iPhone 17 Air
Apple put the A19 Pro chip in the iPhone Air rather than the regular A19 — but it's a slightly cut-down variant with five GPU cores instead of the six in the 17 Pro, no ProRes video support, and crucially no vapor chamber cooling. The result is benchmark scores roughly on par with the iPhone 17 (sometimes lower, because of thermal throttling), but with the 12GB of RAM the iPhone Air keeps apps in memory longer than 8GB phones. Day-to-day everything feels snappy. Under sustained gaming or 4K editing the camera-bar area heats up noticeably and frame rates drop — Ars Technica measured aggressive throttling that put the Air's GPU performance closer to last year's A18 than the 17 Pro. The C1X modem (no mmWave) is up to 30% more efficient than the iPhone 16 Pro's Qualcomm chip and tested faster in weak-signal areas.
The A19 Pro has 12GB of RAM and benchmarks 15% faster in CPU and GPU than the A18 Pro — though we'd expect the Air's performance over time to be worse than the Pro's because of thermal throttling.
Geekbench multi-core hits 9,630 and 3D Mark Wild Life 3,626 — great in short bursts, but it falls off compared to the iPhone 17 Pro in longer tests because of the missing cooling chamber.
Without a vapor chamber, performing intensive tasks heats the area around the camera module noticeably — I measured 115°F on the Air after an hour of Assassin's Creed Mirage versus 110°F on the iPhone 17, and the extra heat throttled performance.
Flipping between apps is essentially instantaneous and demanding titles like Destiny: Rising kept stable frame rates — but watch out, the Air can get a bit warm on the camera bump during prolonged high-performance tasks.
Apps stay in memory longer on the iPhone Air than my iPhone 16 Pro thanks to the 12GB of RAM — Reminders stayed alive across three different grocery store trips with Apple Maps in between.
Apple's new C1X modem benchmarks around 15-20% faster than the iPhone 16 Pro's Qualcomm chip in weak-signal areas, using 30% less energy — but it doesn't support mmWave 5G.
Gaming on the iPhone Air is slightly worse than 17 Pro Max — testing Genshin Impact maxed out, the Air experiences a lot more lags despite the phone being in normal temps.
The A19 Pro is FAST — trades blows with the iMac Pro, RX 570, and even the M4 chip. Apps launch faster than the iPhone 14 Pro and browsing feels app-like rather than web-like.
Ars Technica's graphics tests showed aggressive thermal throttling on the iPhone Air — the GPU sometimes performs more like the A18 from last year's iPhone 16.
OnePlus 15T
Snapdragon 8 Elite Gen 5 paired with 12-16GB LPDDR5X Ultra Pro RAM delivers flagship synthetic scores — Notebookcheck recorded Geekbench multi-core 10,976 and 3DMark Wild Life Unlimited 29,901, on par with the larger Xiaomi 17 and Honor Magic8 Pro Air. The problem is sustained: in the 3DMark Wild Life stress test the GPU drops over 50% and the back of the phone hits 50 °C, which both Notebookcheck and SuperSaf flag as a deal-breaker for long gaming sessions.
Geekbench 6 multi-core hits 10,976 — flagship-tier and within 1% of the average 8 Elite Gen 5 result, so there is no compromise on the chipset versus larger phones.
3DMark Wild Life Unlimited hits 29,901 — 5% above the 8 Elite Gen 5 average and ahead of the Xiaomi 17 with the same chip.
In the 3DMark stress tests the OnePlus 15T shows a sharp drop in performance of over 50%, which significantly lowers our rating.
Wildlife Extreme stress test scores swung from 6,990 best loop to 3,743 worst loop in a single run — the chart is 'quite a bit of a bumpy ride' and performance mode did nothing to stabilize it.
Surface temperatures hit 48.3 °C on the back during stress testing and continued climbing to 50 °C near the camera bump — about 45 °C internal — which seems to be the phone's thermal limit.
Camera
iPhone 17 Air
This is the iPhone Air's single most polarizing area. There is exactly one rear camera — a 48MP f/1.6 Fusion Main with sensor-shift OIS, the same sensor as the iPhone 17's main camera. There's no ultrawide, no telephoto, no macro, no ProRAW, no ProRes, and no spatial photos. The phone offers 'optical-quality' digital crops at 28mm, 35mm and 52mm (2x), then digital zoom up to 10x. Photo quality from the main camera is excellent — vibrant, sharp, strong low-light performance — and the new 18MP square-sensor Center Stage selfie camera is broadly considered the best new iPhone camera feature in years. But the missing lenses come up in nearly every review as something owners notice. Reviewers split sharply on whether the absence is a deal-breaker or a manageable trade-off, with the telephoto loss flagged more often than the ultrawide.
The single 48MP rear camera feels like a real concession on a $1,000 phone — even Samsung managed to fit an ultrawide on the similarly thin Galaxy S25 Edge. Some shots just call for the drama of a 13mm view.
The single 48-MP camera felt extremely limiting — even Samsung managed to fit an ultrawide on the similarly thin Galaxy S25 Edge, and in some low-light shots the iPhone 17's main camera delivered sharper images than the Air.
Despite only having a single rear camera, the Air still takes portrait photos that look practically as good as iPhones with two — Apple reengineered the portrait pipeline to work without stereo cameras.
After six months the one thing I genuinely miss is the telephoto camera — at a function trying to capture a candid moment or shooting landscape photos, the lack of a dedicated telephoto lens is a real limitation.
The iPhone Air feels like jumping back a decade in iPhone camera versatility — having a £999/$999 phone with one camera on the back will be an instant turn-off for many looking for the best camera phone.
The 2x advantage fades quickly once you go beyond it — even the 3x telephoto on the iPhone 15 Pro is clearer and more detailed than the iPhone Air's 2x shot digitally zoomed to 3x, and the gap grows ridiculously wide at 8x.
The new 18MP square-sensor Center Stage selfie camera might be the next big photo revolution other companies will copy — it switches between portrait and landscape orientations without rotating the phone, and auto-frames groups.
Center Stage is the best new iPhone camera feature in years — selfies look so much better because your eyes align closer to the centre of the screen instead of off to the side.
After 10 days in Crete photographing a family vacation on a single rear camera, I realised I'd only twice missed the 0.5x ultrawide — the iPhone Air's main camera at times outperformed my iPhone 15 Pro Max.
Video quality on the iPhone Air remains excellent — comparison clips against the Pixel 10 Pro XL and Galaxy S25 Edge consistently came out on top with better stabilization and brighter, sharper footage.
iPhone Air owners flag the missing telephoto as the regret they keep coming back to — 'rumours suggest the next iPhone Air will include a secondary camera. I genuinely hope it's a telephoto and not an ultrawide.'
Apple says the iPhone Air has the equivalent of four lenses — clever marketing speak for 1x Main, 1.1x Custom Main, 1.4x Custom Main, and 2x Telephoto. Prepare to have serious Telephoto FOMO.
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.
Battery & Charging
iPhone 17 Air
Apple's biggest engineering challenge: fitting useful battery life into a 5.64mm chassis. The Air ships with a 3,149 mAh cell (the smallest in the iPhone 17 lineup), rated 27 hours of video playback versus 30/33/39 hours for the 17/17 Pro/17 Pro Max. The Tech Chap's real-world battery test pegged it at 6h 43m — about 12 minutes behind the iPhone 17 and 76 minutes behind the 17 Pro Max. Reviewers split between 'better than I expected, fine for a normal day' and 'this is the lineup's weakest battery and you'll need to top up before dinner on travel days.' Charging tops out at 20W wired (USB-PD 2.0) and 20W MagSafe/Qi2 — slower than the 40W wired and 25W MagSafe on the iPhone 17. Apple sells a $99 dedicated MagSafe battery pack that adds ~65% charge and is sized specifically for the Air; whether you 'need' it depends entirely on usage and routine.
Battery life is just okay — heavy use brought the battery into the 20s before dinnertime with around five hours of screen-on time, and Apple's recent track record on battery longevity isn't stellar either.
Battery life is better than I expected — five hours of screen-on time with 18% left by 10:30pm. I didn't feel as battery-anxious as I did with the Galaxy S25 Edge.
Streaming video rundown lasted 23h 39m — barely an hour less than a base iPhone 17 — and on a day with over seven hours of screen-on time I still had 25% left in the tank.
After a week I can confidently say I can't make it through a full day on a single charge — on a good day I make it just past dinner, on a bad day I'm on the charger by late afternoon.
The Tech Chap's real-world battery test had the iPhone Air last 6 hours 43 minutes — 12 minutes behind the iPhone 17 (6h 55m) and 76 minutes behind the 17 Pro Max (7h 59m).
Six months in, battery life has not been a problem — the iPhone Air consistently delivers around four hours of screen-on time, comfortably covering my daily needs. For mostly-communication usage it lasts a full day without issue.
Five months on the verdict has stood the test of time — I almost always get through the full day with a 90% charge limit set, typically finishing with over 30% remaining, sometimes 40%.
The iPhone Air is not an endurance champ. It's also not an endurance also-ran — I'm fairly sure it slept through its alarm and forgot there was a race. I never had a full day off the charger.
The Air contains a very small 3,149 mAh battery, but the phone can just about squeak by an 11-hour day for me on a single charge — enough for a normal work day, not a full-on all-day-outside type of day.
Apple's $99 MagSafe Battery is more than erases the size and weight advantage of the Air, spoiling its light weight and thin profile — paying for Apple's particular solution feels sort of silly and only medium-elegant.
Charging is slower than the iPhone 17 line — 50% in 30 minutes instead of 20 minutes — and the USB-C port is limited to USB 2 speeds (480 Mbps) versus 10 Gbps on the iPhone 17 Pro.
Real-world battery from an early adopter: 7:10am to 3:42pm before dropping to 4% — 'not an all-day battery but passable if you don't mind the range anxiety.'
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.
Software & AI
iPhone 17 Air
The iPhone Air ships with iOS 26 and Apple's controversial new Liquid Glass UI — a layered, glass-like design that distorts content behind interface elements. Reviewers like the visual refresh but flag readability issues in places and a higher learning curve. Apple Intelligence is the same as on every other iPhone with 8GB+ of RAM and continues to underwhelm versus Google Gemini. The Air specifically uses Apple's new C1X cellular modem (no mmWave) and N1 networking chip (Wi-Fi 7, Bluetooth 6, Thread). Reddit threads on r/iphone and r/OnePlus call out iOS 26 as a step backward — some longtime iPhone owners have used iOS 26 + the Air's design as a reason to test-drive OnePlus 15 or other Android flagships.
The iPhone Air uses the new Liquid Glass interface in iOS 26 — I like the design overall, but for every helpful update I find five more I hate.
Apple Intelligence – the brand's first AI – isn't even a year old and already feels like an afterthought. It falls so far behind Google's Gemini that it shouldn't have any bearing on whether you buy this phone.
Liquid Glass has potential to be problematic with readability, but I never ran into a situation where I had trouble reading the screen — the Music app's slide-behind-buttons effect adds nice immersion.
Liquid Glass has more to do with marketing than usability — shiny visuals help keynote demos pop, but 'a feature called Liquid Glass sounds sexier than refinements to Safari's tab bar.'
Liquid Glass feels designed specifically for the iPhone Air — you literally just tap on a thin piece of glass with no borders, and the effect lands perfectly on this hardware.
iOS 26 destroyed the experience — the closed ecosystem gets boring after a while. After using iOS 26 on a 17 Pro Max I'm switching to the OnePlus 15.
Apple updated iOS 26 with new AI tricks like pointing your camera at an invitation to add it to your calendar, which works — but Siri still stumbles on requests like 'navigate by bike to Wrigley Field' that Gemini gets right from the jump.
Apple Intelligence still mostly stinks, but that may not be the case starting next year — performance headroom from the A19 Pro could come in clutch when Apple gets its AI plans back on track.
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.
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.

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.
Genshin Impact averaged 60.3 fps over 30 minutes at just 3.2 W power draw, with the phone staying cool to the touch — and Peacekeeper Elite pushed 164.5 fps thanks to native 165 Hz support.
r/Android's reviewer thread flags the same thermal issue directly: 'Gets kinda hot, over 50 degrees in the corner. This is with its very heavy throttling.'
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.
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.
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.
