iPhone 18 Pro and Pro Max: In-Depth Analysis

This design drew mixed reactions at first, but reviewers say it grows on you over time.

The rear Ceramic Shield 2 glass panel is color-matched to the body, giving a more unified look. However, the material tends to show fingerprints easily, a drawback that has been noted.

The iPhone 18 Pro Max weighs 249g, about 18g more than the previous iPhone 17 Pro Max (231g). This is attributed to the larger vapor chamber built inside to maximize performance.

Alongside the added weight, the price has risen 200,000 won from last year. For users who are sensitive to portability and cost, this may influence the purchase decision.

On this generation's iPhone 18 Pro, the Dynamic Island is 25% smaller. This is because the Face ID infrared sensors have moved below the display.

The smaller Dynamic Island improves Live Activities' ability to display side by side. Users can place two apps (for example, maps, music, or a timer) on either side of the Dynamic Island to take advantage of expanded multitasking.

RAM stays at 12GB, the same as before, but memory bandwidth is up 50%, greatly improving overall data processing.

The GPU goes from 6 cores to 7, and the Neural Engine is also strengthened. These hardware improvements deliver a better experience in apps with heavy computation and graphics demands.

Sentences finish generating much faster than on older models.

Inference speed for the local LLM (Google's Gemma model) has also improved significantly. Even with network connectivity limited, such as in airplane mode, the new model's real-world performance is noticeably better.

This prevents performance drops during long, demanding tasks.

In the 3DMark benchmark, the new model averaged 27.3 fps, a clear step up from the previous model's 18.3 fps. That is close to 30 fps by console-game standards, and peak frame rates rose from 20 to 43 fps, markedly improving the gaming experience.

The iPhone 18 Pro Max adopts a thermal design that spreads heat across the whole device. This marks a shift in heat management strategy, which is key to sustaining high performance.

The internal layout has also changed, with the processor and memory placed side by side. The A20 Pro processor connects directly to the vapor chamber, improving heat management efficiency.

Local AI features still work in airplane mode, but complex AI tasks are processed through Apple's private cloud, so they are limited offline.

On-device AI, which relies on device performance, and cloud AI, which uses advanced models in the cloud, differ in usability.

In Auto mode the aperture adjusts to the lighting conditions, and in everyday shooting it operates around f/1.8, similar to before.

Eight functions can be arranged, including focus, shutter speed, and white balance.

The live aperture value is displayed according to the camera in use (telephoto or main), and separate control interfaces for photo and video modes allow customized shooting.

ISO sensitivity was left out of the manual controls, which is a letdown. Precise numerical white balance input is also not available.

The manual shutter-speed range is limited, so long-exposure shooting depends on Night mode, a drawback also noted.

In shooting tests using the variable aperture, the changes in f-stop produced clearly different photo quality. At f/1.48 the background blur (bokeh) is maximized, making the subject stand out.

At f/4, overall sharpness and depth of field are secured, and detail comes through across the frame. Food photos of kimchi and perilla leaves in particular looked crisp.

Improvements to the image pipeline enhance texture and detail rendering, and in low light the phone keeps ISO lower to avoid losing detail, improving overall photo quality.

Overall night photography is much improved, with better noise control than earlier iPhones. The physical aperture is seen as opening new creative possibilities for night shooting.

The iPhone 18 Pro camera creates six light streaks in night shots through its variable aperture. The native Camera app supports slow shutter, enabling a range of night-photography effects.

The new 'Photographic Styles 3' feature allows editing not only color but also texture (soft skin, glow, film). Edits can be made after shooting too, via iCloud sync to a MacBook, expanding post-processing flexibility.

A 'Reference Image' feature has been added to camera settings, recording data that helps verify the authenticity of captured photos. The original data can still be checked even after editing such as Clean Up.

Focus Tracking performs intelligent tracking when you double-tap a subject, keeping focus stable. It is especially useful for telephoto and macro shots, where focus can drift.

Video recording on the iPhone 18 Pro is much stronger. Even after shooting regular video, you can switch to Cinematic mode, which supports 4K 60fps. Timelapse can also be shot in 4K.

The newly added Audio Mix feature lets vlog creators separate and adjust background noise and voice, improving sound quality.

This shows that Pro Controls are still limited at this stage. Compatibility with third-party apps (such as Blackmagic Camera) should improve so that more features become available.

Power consumption is down 15% from the C1X, improving battery efficiency.

Video playback is rated at 43 hours of battery life, and 60W wired charging is supported, making charging faster. However, to get the most from 60W charging you need a recent charger that supports variable voltage.
