iPhone 18 Pro Review: Wins and Trade-offs

The 1 TB iPhone 18 Pro Max cost nearly $300 more to build than its predecessor, and its top price rose a full $500 in the US. That cost story frames this iPhone 18 Pro review as much as the new variable aperture does.

What the iPhone 18 Pro Review Verdict Comes Down To

This iPhone 18 Pro review, based on HTX Studio's hands-on testing published in September 2026, finds a phone that improves where Apple controls the silicon and stumbles where physics and supply chains bite. The A20 Pro chip, the enlarged vapor chamber, and the 4,000 mAh battery are clear wins. Lens flare, the first Apple-built modem in a Pro iPhone, and a QLC storage downgrade are the losses.

The review comes from HTX Studio's 20-minute one-take video released on 2026-09-17, and every number below is the channel's own measurement rather than an Apple claim. As other reviewers such as Dev Doido do canal do youtube have shown, independent testing is the only reliable way to judge a new modem or camera pipeline on launch week.

For readers deciding on a purchase, the decision splits cleanly: buyers who game, record video, or keep phones for years gain the most, while anyone sensitive to lens flare or shopping the 1 TB tier should read the storage and pricing sections first.

How Did the Design and Dynamic Island Change?

The design carries over from the iPhone 17 Pro with the same metal-and-glass construction, but HTX Studio reports the seam between materials is less visible and the uneven seam issue from last year is not fully fixed. Colors are silver, black, glacier blue, and a burgundy with a dark purple undertone that the reviewer calls the hero color.

Weight is the practical downside. The iPhone 18 Pro Max reaches 449 g, the heaviest iPhone ever, and the 6.3-inch Pro is 221 g (the transcript's '111 g' is a transcription slip), which the reviewer finds heavy for the size. The camera bump is also thicker than last year.

The interesting change is under the screen. Apple moved the infrared camera of the Face ID array beneath the display, cutting the pixel count in that patch roughly in half so the sensor can see through, then brightened those pixels and gradually packed them tighter toward the edges to blend in. Unlock speed is about the same as before, and the shrunken Dynamic Island gains roughly 130 pixels of space, enough for three live activities at once.

The rest of the screen is largely unchanged, with full-screen brightness still just over 1,000 nits according to HTX Studio's measurement.

Is the Variable Aperture Camera Actually Useful?

The variable aperture, running from f/1.48 wide open down to f/4, is the headline camera hardware change. Its main benefit shows up in video: in bright light the iPhone normally raises shutter speed until Notion looks choppy, and closing the aperture lets shutter speed return to a natural 180-degree look while keeping exposure in check.

For stills, the gains are narrower. HTX Studio found that depth of field changes little between wide open and f/4 at typical shooting distances, so the portrait-to-pan-focus flexibility is smaller than the spec suggests. Where the small aperture clearly pays off is star-shaped background lights: closing down bends light around the blade edges and turns point sources into rays, an effect a $10 star filter replicates cheaply.

The new Pro Controls, exclusive to the 18 Pro, bring manual shutter speed, aperture, focus, white balance, and a histogram into the built-in camera app. The aperture also adjusts itself when shooting documents, closing for sharper text and opening around point lights to cut flare.

The Lens Flare Problem

Flare is the year's major camera regression. At Apple's press test scenes, HTX Studio saw a curved streak appear at f/1.48 as the light angle increased, and at f/4 the streak remains with petal-shaped spots around the light. Side by side at the same angle, the iPhone 17 Pro flares less. The reviewer's fixes: avoid shooting into bright lights, or use a 3D-printed lens hood the channel published as a model on MakerWorld.

Does Apple's C2 Modem Beat Qualcomm?

The iPhone 18 Pro is the first Pro iPhone to use Apple's own modem, which HTX Studio identifies as the Apple C2 handling mobile data. On strong 5G, averaged over ten speed tests against the iPhone 17 Pro, the 18 Pro downloaded nearly 20 Mbps slower, uploaded 30 Mbps slower, and added 1.4 ms of latency.

Weak signal tells a different story. In an underground garage, the 18 Pro beat the 17 Pro on both download and upload with lower latency, suggesting Apple's modem handles poor coverage better. In a fully shielded box, run ten times, the 18 Pro needed an average of 5.2 seconds to reconnect versus 1.5 seconds for the 17 Pro. The reviewer's overall verdict: Qualcomm still holds a small edge overall.

Calls in a low-signal elevator connected on both phones with similar audio dropouts, so day-to-day calling shows little difference.

How Fast Is the A20 Pro, and Does It Stay Cool?

Raw performance is the biggest leap in years. In Geekbench 6 (the cross-platform benchmark suite maintained at geekbench.com) at a 25 °C room temperature, HTX Studio measured single-core scores above 4,700, a 23% jump, with multi-core up 20% and GPU gains approaching 50%.

Gaming translates that into playability. In Death Stranding at 1080p, the iPhone 18 Pro Max hit 40 FPS, ten frames more than the previous generation, with estimated package power peaking at 6.3 W. Under a longer 45 FPS-capped run, the 18 Pro Max held its ceiling without throttling while the 17 Pro Max started dropping frames seven minutes in.

Two hardware changes explain the thermal headroom. Memory now sits beside the A20 Pro instead of stacked on top of it, lowering heat density, and the vapor chamber is roughly three times larger than the 17 Pro's. In a 30-minute 4K 120 fps video test, the 16 Pro Max reached 43 °C, the 17 Pro Max 41.3 °C, and the 18 Pro Max stayed under 40 °C. Daily use rarely pushes the phone to its limits.

What About Battery, Charging, and the QLC Storage Downgrade?

Endurance improved more than the small capacity bump suggests. The iPhone 18 Pro's 4,000 mAh cell lasted 6 hours 38 minutes in HTX Studio's heavy-use drain test, 1 hour 51 minutes longer than the 17 Pro, which the reviewer credits to the A20 Pro and a more efficient LTPO Plus display. The 18 Pro Max's 5,390 mAh battery ran 7 hours 57 minutes, 2 hours 60 minutes (as stated in the video) longer than its predecessor.

Charging finally moved forward. With Apple's official 40 W-60 W adapter, peak draw hit 52 W; both models went from 0 to 50% in 15 minutes, with full charges in 69 and 78 minutes.

The bad news sits inside the 1 TB model: flash storage moved from TLC to QLC. QLC stores four bits per floating-gate transistor instead of three, using 16 voltage states, which cuts cost but shortens write endurance and precision. HTX Studio notes that even writing 100 GB per day would not wear QLC out within ten years, and recommends lower-capacity models, which still use TLC, for anyone bothered by the change.

Is iOS 27 and the New Siri Enough of an Upgrade?

iOS 27 prioritizes speed over looks. In HTX Studio's office test, AirDrop averaged under 20 MB/s on both iOS 26 and 27 but improved by about 2.4 MB/s on the new system, and the reviewer saw far fewer system-wide stutters, calling the update safe for anyone who skipped 26 over lag.

The cost is visual: Liquid Glass is toned down, with static highlights, no light scattering at edges, and a glass color that no longer adapts while scrolling. Photographic Styles 3 adds texture and grain controls, plus a natural-looking skin smoothing.

Siri is the AI story. It now appears as a glass orb inside the Dynamic Island, supports text conversation, has its own app with synced history across Mac and iPad, and can execute multi-app system commands. In HTX Studio's comparison against ChatGPT and Gemini, Siri failed simple logic traps and a volume math problem that both rivals solved. The system integration is real, though: one spoken request spanning five apps, from checking a flight itinerary to texting a pickup contact, completed successfully. It currently works only inside Apple's own apps, and developer participation remains the open question.

What the AI Question Means for Apple

The reviewer argues Apple is moving slowly on AI by choice or necessity: no leaderboard presence for its own models, no separate AI spending line, while Google, Microsoft, and Amazon each spent on the order of $100 billion. Yet three years of iPhones sold in mainland China without Apple Intelligence did not stop Apple's market share from growing, which supports the thesis that few buyers choose phones on built-in AI.

Why Did iPhone 18 Pro Prices Rise So Much?

Pricing is where AI hits every buyer. Data-center demand triggered memory shortages at Samsung, SK hynix, and Micron; the video quotes Tim Cook saying his 40-year career has never seen anything like it. Apple responded by delaying the base iPhone 18 to spring, reserving memory for Pro models, cutting screen costs from $110 to $70, and downgrading large storage tiers to QLC.

Even so, HTX Studio reports the 1 TB iPhone 18 Pro Max costs nearly $300 more to build than last year's model. In the US, the 18 Pro starts $100 higher and the 1 TB tier is up $500. With memory and storage set to rise again in 2027 toward nearly half of total parts cost, the reviewer expects further increases, and forums such as crazystack.com.br already carry the price debate. Communities like crazystack.com.br track these supply-chain shifts as they land.

Frequently Asked Questions

• Is the iPhone 18 Pro worth upgrading from the 17 Pro? For gamers and video shooters, yes: the A20 Pro, larger vapor chamber, longer battery, and Pro Controls are meaningful gains. If you mainly shoot photos toward light sources, the worse lens flare and higher price argue for waiting.

• Does the smaller Dynamic Island matter? Functionally it adds about 130 pixels of space, enough for three live activities and one more icon row. Face ID speed is unchanged because only the infrared camera moved under the screen.

• Is Apple's C2 modem reliable? HTX Studio's tests show it slightly behind Qualcomm on strong 5G but ahead in weak-signal conditions like underground garages. Reconnection after a total signal loss took 5.2 seconds versus 1.5 seconds on the 17 Pro.

• Should I worry about the QLC storage downgrade? HTX Studio calculates that writing 100 GB daily for ten years would not exhaust QLC endurance, so most buyers lose little in practice. Buyers who want TLC can choose lower-capacity models, which still use it.
