Mid-Range Smartphone Photogrammetry: Poco X8 Pro Max vs iPhone 16 Pro Max

During my Sony A7 V review I argued that professional cameras are "solved" now. There is little left to revolutionize, and not much that still gets in the way of a competent shooter. I think we have reached the same point with mid-range smartphones. Flagships have been taking excellent photos for the past five years, and even mid-range Android phones now have respectable main camera specs on paper. In this article I compare a mid-range Android to a last gen iPhone flagship across three things: image quality, shooting experience, and actual photogrammetry results.

The Hardware: Poco X8 Pro Max and iPhone 16 Pro Max

My mid-range representative is the Xiaomi Poco X8 Pro Max, which GSMArena (my go-to portal for all things smartphones) currently lists as the best mid-range phone on the market. The flagship reference is the Apple iPhone 16 Pro Max, which is the iPhone, and you should expect an excellent camera from it by default.

Xiaomi clearly copied parts of Apple's design language for this generation. The Poco is a flat slab with rounded edges and a strikingly similar naming convention, but it is more plasticky and lighter in the hand. Sizes are similar, the screen is similarly excellent. The current iPhone costs about three times what the Poco does, which is very hard to justify on hardware alone. The iPhone is still a better phone overall, just not three times better. Diminishing returns and brand tax.

The use case here is narrow. I am testing the main 1x camera on each phone, the shooting experience around it, the resulting image quality, and the question that matters for this blog: how good can mid-range smartphone photogrammetry actually be?

Camera Shooting Experience

Here is the most shocking or most unimpressive part of the comparison, depending on what you expected. The cheaper Xiaomi provides the better overall experience for this specific use case. The reason is simple: the Poco native camera app has a full pro mode with manual settings exposed. The native iPhone app does not. And if you go third party, you might not find a complete solution either. I was not able to quickly find an iPhone app that lets me use the full 48-megapixel resolution in RAW while also exposing full manual controls. So much for the Apple experience in this use case.

Everything else is fine on both phones. Both are quick and smooth to operate, autofocus is fast, shutter reaction is immediate, haptics are good. Nothing to complain about even when taking dozens of photos for a photogrammetric scan. Both imaging pipelines produce solid results in JPEG and in RAW. You can find subjective differences you might prefer, but nothing that shows up in a technical evaluation.

Image Quality Side by Side

On paper, the two main cameras compare like this:

Technical image quality is the best kind of image quality. I compared RAW files from each main camera, identical scene, identical processing in Adobe Lightroom Classic.

At the pixel level the photos do show small differences. The iPhone has a touch more detail, or perhaps a touch more in-camera sharpening, less chromatic aberration, and better consistency across the frame at the full 48 / 50 megapixel resolutions. Once both files go through Lightroom, the gap closes very quickly. In practice, both main cameras are good. The ultrawides on both phones are clearly inferior, the Poco's more so, and the iPhone's 5x telephoto adds nothing useful for photogrammetry. None of this is surprising. For more on what sensor design actually does in the background, see Camera Sensor Technology Explained.

Smartphone Photogrammetry in Practice

Photogrammetry stands on three fundamentals: image quality, overlap, and coverage. Image quality is there on a modern mid-range smartphone. The other two come down to technique. There are no special requirements baked into photogrammetry software that exclude phone cameras.

I made a few handheld outdoor scans with the Poco X8 Pro Max, including a pile of logs and a few smaller subjects. They reconstructed cleanly in Pixpro photogrammetry software using default settings. One footnote worth flagging: the Poco did not write GPS data into the EXIF of my RAW photos during these tests. Not a dealbreaker, just a behavior that deserves a dedicated follow-up test, possibly an article on smartphone photogrammetry referencing in whole.

One small but welcome surprise: the Poco native camera app has a toggle for in-camera lens distortion compensation. Disabling it produces raw geometry in the output and allows the photogrammetry software to deal with it, which is always the better choice. The iPhone performs just as well or marginally better on the photogrammetry side, but the two phones are clearly in the same class for this use case.

12 Megapixel or 48 Megapixel for Smartphone Photogrammetry?

Both phones offer their full sensor output at 48 or 50 megapixels alongside a binned 12 megapixel mode. The right choice depends on the scan. For larger projects with hundreds of photos, 12 megapixel RAW is the smarter default. The files are lighter, processing is faster, and the optical imperfections at the edges of a 50 megapixel frame are quietly hidden at the lower resolution. For a quick single orbit of a small subject where you actually want every available pixel, the high-resolution mode is the better call.

Worth remembering that these are quad-Bayer sensors. The 48 or 50 megapixel number is not four times the real detail of the 12 megapixel output. There is more detail in the higher mode, but the marketing math is inflated by the sensor design. Use the higher resolution when you actually need it, not by default.

Tips for Photogrammetry with a Smartphone

A few things worth knowing before you point any phone at a subject and start scanning.

Use only the main 1x camera. Ultrawides distort, telephotos lack the sensor area, and switching between focal lengths mid-scan confuses the alignment. Stick to one lens.

Shoot RAW if your camera app supports it. RAW preserves the dynamic range that the pipeline relies on for clean feature matching, and it gives you headroom to correct exposure across the dataset before processing.

Maintain at least 80 percent overlap between photos and walk a steady arc or grid around the subject. The phone is light enough that you can shoot at a fast shutter speed and stay sharp.

Conclusion

Mid-range smartphone cameras are good enough for photogrammetry today, full stop. The main 1x cameras on phones like the Poco X8 Pro Max sit close enough to the iPhone 16 Pro Max that the difference is mostly invisible once the photos go through a normal RAW processing pipeline and into reconstruction. If you have a recent mid-range Android in your pocket, you already have a workable photogrammetry tool for casual scanning, documentation, and learning. For serious survey or commercial work, a drone or a proper camera is still the right call. For everything else, the phone is enough.
