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.

    Apple claims ~25 hours total using the charging case (the Air Pods themselves have 5 hour life). That should be enough to get through the day Reply

    I think the big leap was 5->6. Since then not a lot has *noticeably* changed (I.e. outside the spec sheet). Reply

    How courageous.

    I recently had to go back to a 5s. It's rather good.

    Which SoCs are faster than the A10 and in what respect? Which phone has faster NAND storage than the iPhone 7? Cameras in Android systems have largely caught up, but are not universally accepted to be better. Yes, sensor size matters and that does help with detail, but so does color accuracy and overall ISP ability. I'd suggest they're more on par than you suggest. Reply

    "faster in lots of aspects"
    Hmm, maybe next year the SD830 or E8895 can finally start beating the iPhone 6 in single threaded performance.
    "UFS 2.0 is comparable with Apple"
    Sequential reads and writes in the 6s/7 are approximately twice as fast as the fastest UFS storage in androids. In randoms, everyone is about equal.
    "have been better for a while"
    Perhaps, to certain people, because over saturation is highly pleasing to the eye. But Apple has always remained relatively true to life, and being able to outperform many Android phones with much larger sensors is a testimony to their ISP.
    "6S has better battery life"
    The 6S has battery life barely comparable to the 6, while the 7 has battery life comparable to the SE, which lasts nearly 3 full hours longer than the 6S.

    "Sequential reads and writes in the 6s/7 are approximately twice as fast as the fastest UFS storage in androids. In randoms, everyone is about equal"

    except that GSMArena tested the 32Go version as well, and it appears that the memopry is SIGNIFICANTLY slower. And that is an euphemism as the write spead appears 8 times slower and it showed a 4 times longer time to trim the same 4K video.
    So only the 128Go version seems to be in line or slightly above the competition but the 32Go seems dog slow.
    It would not be surprising of Apple, being cheap as usual.

    Posted without a trace of irony considering Android manufacturers still can't beat the 2 years old iPhone 6 in CPU performance. Reply

    Yeah, no.
    Do you have evidence that there exists any android soc that is "faster" than these apple socs?
