Still Image Performance

Now that we’ve discussed the basics of the iPhone 7 and 7 Plus camera we can start to get into how it actually performs relative to the iPhone 6s and 6s Plus as well the current competition on the market. While we normally run an ISO test to check spatial resolution this has been deferred to a future portion of the review. Unfortunately we don't really have the ability to do time-invariant testing here in a serious manner to the same extent that an OEM might, so we're effectively limited to tripod comparisons of real-world subjects.

Daytime Photography

In this kind of scenario the iPhone 7 and 7 Plus are directly comparable in the 1x mode. Because the primary camera has OIS and the secondary camera doesn't, it looks like it's fairly difficult for Apple to do an exact pixel to pixel correlation to the extent that the two outputs can be merged into a single image. As a result it's fairly obvious that the 1x mode has less detail than the 2x mode here. I can really see how this would be useful in general, as the longer focal length means more detail relative to anything else on the market but also allows for more interesting framing. The 1x camera is identical to the iPhone 7, and here it's definitely noticeable that the iPhone 7 can't quite keep up with the Galaxy S7 or HTC 10 in sheer detail in these kinds of shots.

In the interest of trying to not just take a single landscape photo and declare it to be a representative sample for all photos ever taken of all time with a smartphone in daytime conditions, I went ahead and took another sample shot of a mostly static subject. Here the iPhone 7 Plus in 1x mode is pretty much comparable to the iPhone 6s and Galaxy S7 as far as detail goes. I would argue that the HTC 10 captures slightly more detail at the center, but this probably isn't a surprise when the sensor is significantly larger. It's also worth noting that the iPhone 7 Plus manages to show better dynamic range here as the highlights off to the right retain more color detail than most devices tested and the shadows contain more detail that what is found on the Galaxy S7 or the iPhone 6s Plus. Once again, at 2x the iPhone 7 Plus is really just ridiculously good at capturing the sheer amount of detail that the tree has which isn't really captured by the 1x mode as most of the detail has to be blurred away to avoid aliasing. It's truly impressive how the iPhone 7 and 7 Plus are actually capable of keeping up with the Galaxy S7 despite a smaller sensor, and we're really seeing the product of Apple's ISP lead here.

Low Light Photography 1

It probably is worth mentioning here that in low light the iPhone 7 Plus doesn't actually use the secondary camera at all due to its smaller aperture and lack of image stabilization, which means that the iPhone 7 and 7 Plus are identical in low light performance. Interestingly enough detail is fairly comparable between the iPhone 6s Plus and iPhones 7, with some minor adjustment to favor more noise reduction. I'm inclined to say that the Galaxy S7 and iPhone 7 are basically comparable here but the oversharpening on the Galaxy S7 remains fairly obvious and I would expect it to outperform in detail here but it's just comparable to the iPhone 7 due to the rather smeary noise reduction. The HTC 10 is the clear winner here as far as detail goes but both the Galaxy S7 and HTC 10 really oversaturate the green shrubs while the iPhone 7 is much closer to what it should actually be. The oversaturated, smeary look that seems to dominate the Galaxy S7 output continues to be seriously off-putting for me.

Low Light Photography 2

It's interesting to see how Apple's noise and noise reduction seems to have changed from the 6 to 6s to 7 here. Detail is functionality identical but the iPhone 7 and 7 Plus clearly handle shadows better here as there's more detail and noise is controlled noticeably better with better detail and less visible noise. It's really impressive what Apple's processing is able to pull off here when sensor size and sensor technology hasn't really advanced that much from the iPhone 6s to iPhone 7. This is especially obvious when compared to the Galaxy S7, which has comparable overall detail but the noise reduction used is much more splotchy and has obvious oversharpening if you look too closely. Again, relative to the HTC 10 the sensor size deficit is very obvious here if you try to read the text on the trash cans, but the HTC 10's gamma and noise reduction algorithms are just not competitive in the shadows and it's obvious that there are uncorrected optical distortions in the light flares. The HTC 10 also tends to feel like it has a filter over the entire photo that makes it look a little soft compared to the iPhone 7 even if it does have better detail in some parts of the frame.

Low Light Photography 3

For whatever reason this scene always seems to at least mildly challenging. Here we can really start to see the softness that I'm talking about with the HTC 10, as the white pillar "bleeds" a bit into the brick wall exterior of Knudsen Hall. Detail on the iPhone 7 and 7 Plus remains comparable to the iPhone 6s Plus, but with noticeably less noise. The Galaxy S7 manages to deliver similar levels of detail to the iPhone 7, but it definitely oversaturates the red brick colors which might be appealing but really isn't accurate when you look at the RAW reference. The noise reduction on the Galaxy S7 is noticeably splotchier here and gets much worse if you look at the top right quarter of the photo. I would actually say the iPhone 7 outperforms just about everything here but the LG G5, which has better detail but a really strange color rendition.

Overall, the iPhone 7 camera is impressive and I would argue is holistically a better camera for still photos than the Galaxy S7 on the basis of more accurate color rendition, cleaner noise reduction, and lack of aggressive sharpening. It may not be as lightning fast as the Galaxy S7 or have as many party tricks, but what it does have is extremely well executed. The HTC 10 is definitely better than the iPhone 7 at delivering sheer detail when only comparing the 28mm focal length camera, but the post-processing has a tendency to bleed colors in low light which sometimes causes the images to look a bit soft. In daytime the iPhone 7 Plus' 56mm equivalent camera helps to keep it well ahead of the curve when it comes to sheer detail and really is a revelatory experience after years of using smartphone cameras that have focal lengths as short as 22mm and can't really capture what the eye sees. However, in low light the sensor size deficit really starts to become obvious. I suspect the Pixel and Pixel XL will make this especially clear. If there's really no room to go up the ladder in sensor size, Apple really needs to consider some radical approaches to improving sensor sensitivity such as RWB pixel layouts or using the dual camera for an oversampling scheme.

    Yeah, that statement made no sense. He said it was fairly thick relative to the iPhone 6S which was thicker at 7.1mm so...??? Reply

    The whole thing about thickness and "freezing motion" made no sense. He probably didn't have anything else to prove his "point" that iPhones faced little competition in 2014/15.

    The context of AT reviews has been broken for a while. Just like someone else here suggested; they should only focus on reviewing parts of tech in which they have more knowledge about and accurate tools to measure. Hopefully using better "tools" than browser benchmarks (!).

    For better or worse, you will be seeing browser benchmarks for years to come. As few developers care to tackle cross-platform system benchmarks, we aren't left with very many tools to use. Never mind the fact that browser performance is still a major part of the overall smartphone experience. Reply

    Your perception and truth and credibility is up to you. But if it is worth anything, I'd suggest you change the title/section to "Mobile Safari Performance (vs Mobile Chrome)", or scratch it off entirely.

    What you're currently doing is provide false information (and lies) to your readers, unless the purpose of this site has changed to "providing fanboys and fools with fuel for their petty flamewars". You're making yourself look like an Apple shill, or worse, you're providing a cover up for Google's failings in optimizing their browser and platform for the latest Cortex and custom cores.

    If you have no tools for accurate measurement, like you just stated, then you should skip this section all together or narrow it down to Apple SoC comparisons ONLY, with a big fat disclaimer explaining why that data CANNOT be applied/compared with other SoCs and platforms.

    Yes, they should have included GeekBench as a cross platform SoC test. THAT would have shown that... oops... The A10 still blows away everything else in single core by a huge margin.

    From what I've seen, using other browsers on Android doesn't help much. But if you'd like to point to some benchmarks we're all eyes.

    The smartphone SoCs have reached a point where their performance differences are pretty much superfluous. Yeah, we all know that the Apple SoC is significantly better than Snapdragon 820. But that's just like saying that if you bring to a race track Lamborghini, Ferrari, and McLaren and race them, then you will find out that one car is fast than the rest, which is somewhat irrelevant outside of such racetrack. The truth is that smartphone SoCs have gotten to be fast enough that a three year old Nexus 5 is still fast and more than adequate for day to day duties. On the other hand, apple's deletion of the headphone 3.5mm jack and its refusal to allow the users to upload the multimedia into the device bypassing the iTunes GARBAGE is a big loss. For these reasons, in my book, a 200USD Moto G is still a lot better than an iPhone 7, even if the iPhone 7 was also sold for 200USD. Reply

    I can get the multimedia to my Apple phone without the iTunes GARBAGE. Maybe you have a different model from me or something. ;) Reply

    Which is why both XDA and Anandtech have found that the Note 7 was incredibly slow to load apps in Discomark, which definitely impacts daily usage. Reply

    Forget GeekBench. Stick with Antutu. More representative. Reply
