Conclusion & End Remarks

We’re coming to an end of what’s a very long review for what probably the most awaited and important Android devices of 2020. Samsung has made several promises as to what the S20 series brings, with the majority of the hype being surrounded around the new cameras, with the other key point being the 120Hz display of the phone.

Starting off with the general design updates of the S20 series, I’m actually extremely happy as to what Samsung was able to achieve with the smaller S20 and S20+ phones, and in part with the S20 Ultra. Samsung’s flattening of the display along with the larger curvatures of the back glass means that, ergonomically, the new phones are a very big improvement over the last few Galaxy flagship generations, allowing the phones to feel smaller than they are – even the humongous Ultra.

The S20 Ultra is in a class of its own when it comes to its size. It’s bigger, thicker, and just feels heftier than anything else Samsung has brought to market in the flagship category. I’m sure there’s plenty people will very much welcome these devices as they’re willing to use bigger and bigger phones, though I’m more prone to stick with the S10+, as I feel the Ultra is just a tad too large.

The other drawback of the Ultra is the camera bump. It’s not that I have anything against camera bumps, it’s just that I feel Samsung could have implemented it with better design elements – particularly the “gasket” – and the gaps around the camera protrusion feels cheap and is very prone to collecting dust. I didn’t have the same reservations about the S20+’s camera design, as that one's perfectly fine and reasonable in my opinion.

The screens of the S20s are all excellent in terms of their quality. The highlight feature of the phones here is simply the 120Hz ultra-high refresh rate. It’s an amazing feature that by itself is able to differentiate the experience of the S20 series, bringing you a much smoother device experience than ever before.

The performance of the S20 series is also excellent. Both the Snapdragon 865 and the Exynos 990 are able to deliver top-notch system performance on the new phones, although the Snapdragon does have a slight edge. Together with the 120Hz refresh rate, these are the snappiest, most responsive devices on the market right now – no contest.

However, the 120Hz refresh does come with quite the battery life cost. Expect a 20-25% reduction in battery life when you use the feature. Here even though the new phones come with extra big batteries, going up to 5000mAh on the S20 Ultra, it’s not sufficient to counteract the high refresh rate power draw. And if you’re coming from a previous generation flagship phone, the net result will be a battery life downgrade. It’s possible that Samsung could improve things with firmware updates and actually introduce a switching refresh rate mechanism to improve the current inefficient system – but we don’t know if and when they’re going to do that.

The power efficiency differences between the Snapdragon and Exynos are acceptable in everyday usage, however if you’re a power user, particularly in gaming, the Exynos 990 won’t fare very well. The M5 CPU is a disappointment and isn’t competitive with the Cortex-A77 cores of the Snapdragon. But at least it’s the last generation of Exynos SoC having to live with such a disadvantage. The GPU performance of the SoC is also very disappointing, as the long-term performance will only be around half of the Snapdragon models.

Then there’s the cameras. Samsung put such an emphasis on the camera capabilities of these phones that frankly we expected the most amazing results ever. In my mind in particular I had expected for Samsung to compete with Huawei in terms of picture quality, both in daylight and in low-light.

In daylight, the one strength of the phones that does materialize is the S20 Ultra’s telephoto module. The sheer hardware prowess of this camera is leaps ahead of other devices in the market right now. Sure, Samsung went a bit too far with proclaiming it’s able to achieve up to 100x zoom – those pictures are just a blurry mess. But it does fare very well at 10-20x magnification, and provides some shots that you normally wouldn’t think possible out of a phone.

The main camera sensors on the other hand I feel fall short of the high expectations. Yes, they are better than what we see on the S10 series, however Samsung here is still falling short of proving the same quality that Apple achieves on the iPhone 11 – and it’s also optically inferior to Huawei’s newest devices. I just don’t quite see why the 108MP sensor on the S20 Ultra had to be an 108MP sensor, as I don’t feel that number of pixels translates in anything meaningful in any of the camera usages of the S20 Ultra. In fact, more often than not, the S20+’s 64MP camera unit is able to take more detailed pictures.

The S20+’s 12+64MP combination is I think more versatile than that of the S20 Ultra, and the area where this shows the most is in the 1.2-3.5x zoom range, where the Ultra just falls apart, but the S20+ still is able to take perfectly detailed pictures. The ultra-wide-angle’s reduced resolution from 16MP to 12MP is a straight downgrade for daylight pictures, it does however make this up with better low-light pictures.

Then there’s low-light, which is just a massive mixed bag of results. Here it’s clearly a matter of the software not being optimized, as sometimes all the S20 perform worse than the S10 phones. Yes, in the perfect conditions the phones are able to shine – particularly the Exynos models, which currently have much better low-light camera calibrations and processing – but even in that best-case scenario Samsung is far behind the results that Huawei is able to achieve.

Megalomania Devices - But Still Good Phones

I've taken to calling the S20 series megalomania devices because, $1400 price tags and all, they’re overpromising and underdelivering – however that doesn’t mean they’re bad phones. Other than the display size and the excellent zoom module, I don’t really see the value in the S20 Ultra over the S20+. The 108MP camera in particular feels underutilized. Given the steep price premium over the S20+, I’m having a hard time rationalizing this phone over its smaller siblings.

The S20+ I feel is a proper successor to the S10+, and I’m even willing to switch over to it as a daily device. The 120Hz screen remains incredible no matter the battery life impact, and the cameras are still plenty good, even if not class-leading. The users in Snapdragon markets in particular end up with a device that makes very few compromises and is seemingly worthy of being a top class 2020 flagship. I just hope that Samsung will be able to resolve the camera discrepancies between the different models, as well as generally improve the camera picture quality over the coming months. If they achieve this, then I feel that the new phones would warrant their release price tags.

    No need for me to praise this review any longer. Still, I must nitpick. The 3dmark GPU test always has caveats in your reviews. Drop it if you feel it is detected by OEMs or it's a false GPU test like the physics one.

    On web tests. I read on wiki that JetStream is an Apple made test, literally. Wouldn't you say that's a big caveat when testing against ios? Similarly Speedometer is developed by the webkit team at Apple. With Android webview based on Blink, not webkit, wouldn't Android smartphones be at a disadvantage against iphones? I don't see Kraken(Firefox) or Octane(Google) being used.

    Kraken would actually be neutral to both. Other 3rd party tests might be Testdrive(Microsoft) or Basemark.

    I don't think that the fact that the WebKit team made those tests is a valid argument against using them. You can go and read the source JS yourself if you wish, and they're industry accepted benchmarks. Both Kraken and Octane are ancient and outdated and we dropped them just like we dropped SunSpider of the early days.

    Thank you for the prompt answer.

    Thank you Andrei, again the most comprehensive and reliable set of samples anywhere!
    There seems to be considerable sample variation again (last time with Samsung was the main module since S9 with the variable aperture) in the UWA, S20+E and S20UE should have absolutely identical UWA performance but the S20UE seems to have far worse sagittal resolution than the S20+E, and Samsung's processing isn't that good in the first place, considering the 12MP 1.4μm could produce incredibly sharp pictures as that been the specs of the Pixels' main module for generations.
    I don't regret their switch to f/1.8 because the old module that went up to f/1.5 wasn't sharp wide open, especially in the corners, but a further two stops' variation to f/3.3 could be useful for more DoF in closeups provided inserting that physical aperture into the tiny module doesn't compromise the optical design otherwise.
    This time around the E seems to generally outperform the S, except in color as E doesn't seem to have proper color fidelity...almost as if chroma NR is set too high even in broad daylight, and the "hybridization" of the digital zoom, in which the E clearly uses a smaller portion from the periscope's readout than the S in the resulting merge. Speaking of the zoom, S20+ still performs slightly worse at 2x(16MP readout) than S10's native 12MP, though the difference is small and could be down to lens variation. Considering S10U's Z height, they could've easily fixed the S20U like Xiaomi, going 1/2.3" f/2 12MP with the 2x. Xiaomi used it despite a 4-1 bin, all the more reason to use it with a 9-1 bin. S20U's corner performance at 3x would also be much improved.
    Regarding the comparison with the Fuji though, I suspect your unit has trouble focusing to infinity correctly, because the train and forest samples show clear superiority of the Fuji's zoom. I especially recognize that kind of slight haziness as being very responsive to dehaze and low radius sharpening in LR and would result in far more detail with extraction in post. Also, with an ILC, there's always stopping down a little for more sharpness and more DoF.
    Regarding the full res modes, it's not worth storing 108MP of data with the CFA asking for a 9-1 bin, of course the 64MP would be better, without the RAW it's hard to say for sure, but the 64MP seems to be quad bayer.

    I don't agree with your remark about the night comparison with Mate30P though, the UWA is not "UW" so it has better image quality, that's true, and the night mode of the Mate30P is far superior, that's also true, but not auto mode, nor any aspect of the telephoto as it's clearly using a crop of the main for 3x. Samsung does attempt to use the 4x for telephoto and although there's a significant issue of chroma noise, it's far sharper than Mate30P's crop, with at least twice 3 times the effective resolution in night mode. With S20U you could also crop out a single shot 3-4x of similar brightness to the Mate30P crop, but it's just a crop.
    As for the potential of P40P surpassing S20U, that model operates on a 9.4MP crop by default, interpolated to 12.5MP which clearly has consequences. In daylight it's often a regression compared to P30P (much less match Mate30P), and in night shots using the current firmware it has severe color issues of rendering large portions of the scene as a crimson red, so it's hard to say at this point too.
  • s.yu - Friday, April 3, 2020 - link

    Oh, there's exception of the Mate30P auto mode in the last sample, but the night mode isn't constantly superior either.

    I've been looking forward to getting one of these, not sure which yet. The fly in the ointment now is that I won't see my Mom (who gets my old S9+) until the Fall due to the whole COVID problem, not to mention less income. That will weigh heavily on sales of what is otherwise an amazing looking phone for me.
  • 29a - Friday, April 3, 2020 - link

    How large are the picture file sizes created by this thing?
  • BedfordTim - Sunday, April 5, 2020 - link

    The same size as any other 12MP camera. They will depend on content, hdr, motion and compression options but I would expect about 36MB for a raw image and 8MB for a high quality jpeg.
