In the world of smartphone photography, the battle for the best camera is an ongoing saga. With flagship models like the iPhone 17 Pro Max, Galaxy S25 Ultra, and Pixel 10 Pro XL boasting impressive megapixel counts, it begs the question: does more megapixels actually lead to better photos? To answer this, I conducted a series of tests to compare the full-resolution capabilities of these top devices.
Each of these smartphones offers the ability to shoot in full resolution, but users often default to lower settings due to storage concerns or perceived quality differences. In this article, we’ll explore the results of my full-resolution tests, examining how each phone captures detail and clarity in various conditions.
Apple iPhone 17 Pro Max: 24MP vs 48MP
The iPhone 17 Pro Max typically shoots at 24MP, but also provides options for lower (12MP) and higher (48MP) resolutions. In my first test, I captured images of buildings near Bryant Park on a cloudy day. The higher resolution shot was noticeably brighter, yet when inspecting details, both the 24MP and 48MP images displayed similar levels of clarity. Zooming in on labels of drinks showed virtually no difference between the two resolutions.
In another shot of a Call of Duty billboard, the 48MP did reveal slightly sharper text, especially on the ESRB rating. However, for most practical purposes, the distinctions were minimal.
Samsung Galaxy S25 Ultra: 12MP vs 100MP
The Galaxy S25 Ultra, equipped with a whopping 200MP main camera, offers a striking contrast to its default 12MP mode. On paper, one would expect a significant improvement in detail. However, I found that the 12MP photo held its own against the 200MP shot, showing no substantial differences in dynamic range or detail. The 200MP image did have slightly sharper text on labels, but the improvement was not dramatic.
Despite capturing over 15 times the number of pixels, the difference in real-world applications was barely noticeable, particularly when comparing shots of buildings and product labels.
Google Pixel 10 Pro XL: 12MP vs 50MP
The Pixel 10 Pro XL showed some improvement between its 12MP and 50MP shots, particularly in terms of detail in the brickwork and text clarity. The 50MP image did exhibit sharper edges on fine print, which was a step up from the lower resolution. This phone’s image processing capabilities might be responsible for the enhanced clarity, but again, the differences were subtle.
When examining close-ups, the 50MP shots outperformed the 12MP variants, particularly with intricate details like the ESRB rating on the Call of Duty billboard.
OnePlus 15: 12MP vs 50MP
In my final test with the OnePlus 15, a side-by-side comparison of the Call of Duty billboard revealed no difference at all between the 12MP and 50MP images. Both resolutions yielded identical results, which was disappointing given the file size discrepancy. The 50MP photo was significantly larger, yet it produced no added value.
Conclusion
After testing these flagship phones, it’s clear that shooting at the highest resolution doesn’t always translate to better photography. While the Galaxy S25 Ultra and Pixel 10 Pro XL showed some differences, they weren’t substantial enough to warrant abandoning lower resolutions entirely. Additionally, opting for lower resolutions can save valuable storage space on your device.
Ultimately, the choice of resolution may come down to personal preference and specific use cases, but for casual photographers, the default settings often provide more than adequate quality.
