iPhone 17 Air vs Vivo X300 Ultra

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.

Vivo X300 Ultra

Snapdragon 8 Elite Gen 5 plus Vivo's custom imaging silicon delivers flagship benchmark numbers and strong gaming, but the camera-heavy hardware runs hot — sustained stress tests show roughly 60–65% stability and the camera app warms it up fast.

• At the heart is Qualcomm's current flagship Snapdragon 8 Elite Gen 5, supplemented by Vivo's custom VS1 and V3-Plus imaging chips.
• It boots in 16 seconds (vs 21s for the S26 Ultra and 19s for the iPhone 17 Pro Max) and posts an AnTuTu score over 3,800,000, stronger than Samsung.
• In a prolonged stress test it throttled CPU performance to about 60% of peak — in line with other high-powered flagships — and 3DMark stability landed around 63–66%.
• It gets a bit hot after 30–40 minutes of gaming, but with no throttling even past an hour and never uncomfortable to hold; boost mode at max graphics gives around 4 hours of Wuthering Waves on a full charge.
• Native 120fps gaming with smooth/very-high graphics in many titles, with temperature barely crossing 35°C and power draw around 4W in battle-royale modes.

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.'

Vivo X300 Ultra

Vivo grew the silicon-carbon cell 10% to 6,600mAh while keeping the body the same size. Real-world endurance is strong — ~16h active-use score, ~7h heavy screen-on, 13–14 hour days with charge to spare — and 100W wired refills it in under an hour, with 40W wireless.

• Vivo increased the battery by 10% to 6,600mAh despite the phone being practically the same size on paper.
• In our battery test it earned an active-use score of almost 16 hours; 100W charging took it 0–66% in 30 minutes and a full charge in 46 minutes, plus 40W wireless. A charger is in the box except in Europe.
• On the China version I'm finishing entire 13–14 hour days with 25–30% left; the global version keeps the 6,600mAh cell so battery life should comfortably last 12–13 hours of heavy use.
• Getting nearly 7 hours of screen-on time with very heavy usage from the 6,600mAh silicon-carbon unit, with 100W wired and 40W wireless charging support.
• After a 4-hour heavy-usage simulation the phone still had ~45% battery left, which is solid by today's standards, and 100W wired charging takes about 45 minutes to full.

iPhone 17 Air

At $999/£999 the iPhone Air is sandwiched in the middle of Apple's lineup in a way no reviewer can comfortably justify on paper — $200 more than the iPhone 17 (which has more cameras, more speakers, longer battery, faster wired transfers) and only $100 less than the iPhone 17 Pro (which adds 4x/8x telephoto, vapor-chamber cooling, ProRes recording, and Apple ProRAW). The value proposition rests entirely on whether you assign meaningful price to thin-and-light design alone. Most reviewers conclude the Air is for a specific shopper, not the typical buyer. Apple's own results back this up: MacRumors reported in February 2026 that sales were so soft Apple delayed the Air 2 model. Reddit threads cite price as the single most common reason buyers chose the iPhone 17 or Pro instead. Owners who do buy it tend to love it disproportionately — phrases like 'best iPhone since the X' and 'best phone I've ever owned' recur in Reddit and MacRumors comments — but the catalogue of compromises (camera, speaker, battery, USB 2, no mmWave) make this hard to recommend for most people.

• For most people the iPhone 17 will be a better choice — it has a better balance of power, battery life, and a more versatile camera system. The Air's asking price is too high.
• For anyone who puts a premium on style and sleekness, the iPhone Air is without a doubt Apple's coolest handset in years — even if it's not the most affordable iPhone or the one with the most cameras.
• For the right person, this iPhone Air is the most enjoyable phone experience I have had in the past decade — but most people are better off with the iPhone 17 ($799) or iPhone 17 Pro ($1,099).
• Sales have reportedly been so low that Apple is delaying the next-generation iPhone Air model — the biggest thing wrong with the iPhone Air is its $999 price tag.
• Considering the iPhone Air is priced at $999, the standard iPhone 17 starts at $799, and the Pro iPhones at $1,099, I find it very hard to recommend the Air. Get the Pro instead — it's tremendous this year.
• There's nothing about the iPhone Air that's objectively better than the cheaper iPhone 17, except the A19 Pro chip — and that's only marginally better here. You're paying for what many will find subjectively way cooler.
• If it were closer to the base iPhone 17 on price, or closer to the 17 Pro on features, I'd happily recommend the iPhone Air to anyone. As it is, it's not hugely surprising it is missing the mark for many people.
• If you want an iPhone that looks incredible and feels even better in the hand, the iPhone Air is for you. Just know that experience will come with tradeoffs.
• Why pay $1,000 for a bad phone when you can either pay an extra $100 or save $200 for a better phone? — the top-voted MacRumors comment captures the dominant value criticism.
• The Air's price is the dealbreaker — at $200 more than the base iPhone 17 with LESS to offer (1 camera, 1 speaker, subpar battery), the design and build quality become moot for most buyers. If priced lower than the 17, it'd be a success.
• I've had it for a month and I LOVE THIS PHONE — it feels and works way smaller than other iPhones, doesn't take up my entire pocket, doesn't take two hands to use, still has a large screen, and it feels better than any phone I've ever had.
• After three days of unbroken use the iPhone Air has sold me on the value of a 'heftless' phone — but it's not a slam-dunk and I wish it didn't cost $1,000.

Vivo X300 Ultra

This is a deliberately niche, camera-first flagship: roughly €1,175 in China for 512GB, around £1,399 globally for the phone, and close to €2,600 for the full kit. For the people it's aimed at it draws some of the strongest praise of any 2026 phone; for everyone else, a cheaper X300 Pro or the Oppo Find X9 Ultra may make more sense.

• Last year's X200 Ultra was, in my opinion, one of the best smartphones of 2025 — and this is the best smartphone I've ever used, with the best camera application I've ever used, provided with zero script from Vivo.
• The cameras are nothing short of amazing — this is the best Android camera phone, with image quality better than anything from Samsung.
• The versatility here is just ridiculous — more like a phone in a camera than the other way around, a camera system built from the sum of its many parts.
• If you accept the 35mm main, are willing to tolerate AI processing in some scenes, and don't mind the front-camera stabilisation limits, this Vivo is an excellent choice.
