Apple iPhone XS Max vs Samsung Galaxy S20 Ultra: Is the iPhone Good Enough?

author Luis Silva (May 2020 Updated: August 2021 - 6 min. reading time)

The Galaxy S20 Ultra is more expensive than the iPhone XS Max, but it's the smartphone you should pick.

It has a better display, better battery life, more internal storage (128GB vs. 64GB), and external storage.

Are there other things worth mentioning?

The Galaxy S20 Ultra also features a higher refresh rate, Always-On, larger (+0.4") display, better peak brightness, a telephoto lens (+51 mm), faster-charging speeds (45w vs. 15w), faster wireless charging (15w vs. 5w), reverse wireless charging, and more RAM (12GB vs. 4GB). But with the iPhone XS Max, you can get a cleaner user interface.

How much will the additional specs cost me?

If you're considering a new and unlocked smartphone, it'll cost you around $305 more.

Is the iPhone XS Max still worth getting in 2021?

The iPhone XS Max is still a great phone, even in 2021, and while it isn't the best device out there, at least it's more affordable now. Having said that, the OnePlus 8 Pro has better performance, better cameras, more storage, a better optical zoom, faster charging, more RAM, better display, and reverse charging.

Is the Galaxy S20 Ultra still worth buying in 2021?

Of course, I still recommend the Galaxy S20 Ultra in 2021. You'll love it for its good cameras, good battery life, excellent glass protection, optical zoom, and fast charging. But don't just ignore the Oppo Find X2 Pro.

Are you consider an upgrade and switching from apples to robots? Not really?

That's ok. Either way, you're in the right place.

In March of 2020, Samsung launched its Galaxy S20 Ultra. The iPhone XS Max, however, saw the light of day in September 2018.

Here you can look at the iPhone XS Max and the Galaxy S20 Ultra, compare each other's features, and decide which one is best for you. Let us delve into the finer details.

Which One Has The Best Performance?

Performance-wise, Geekbench 5 (IOS)(Android) scores the Galaxy S20 Ultra 2% ahead in the multi-core ranking. Overall, you wouldn't feel that much of a difference between them. The iPhone is a bit more responsive to tasks like rotating the phone to landscape mode because it is a more optimized OS.

We can classify the Galaxy S20 Ultra as a lower high-end.

PS: The Qualcomm Snapdragon 865 (with the Adreno 650 GPU) and the Exynos 990 (with the Mali-G77) are market-dependent. Click here for more info.

There's a performance increase of about 15% on the 865 for the Galaxy S20 Ultra.

Which Phone Has The Best Display?

The Galaxy S20 Ultra is the winner here, and the difference is considerable.

If you prefer a smartphone with a big display, the Galaxy S20 Ultra is your holy grail. At least it's enormous when compared to the average phone for its price range.

If you fancy edge-to-edge displays, there's one more reason to consider the Galaxy S20 Ultra.

Very few rivals share this maximum brightness. Usually, they rarely stay far from 743 nits, but the iPhone XS Max can only do 29% below that.

If a device can't go over 500 nits, it isn't your best option for HDR content and outdoor readability. Relating to HDR:

Bearing in mind the iPhone XS Max, 89% of its rivals can play HDR content. Plus, all have an AMOLED screen, and 93% have an Always-On display.

Regarding the Galaxy S20 Ultra, I should say that 96% of its rivals can play HDR content. Plus, all have an AMOLED screen, 88% have an Always-On display, and 76% have Gorilla Glass 6 or better.

You should note that the iPhone XS Max is in the neighborhood of 40% above other smartphones from its price range. Although the Galaxy S20 Ultra is the clear winner.

About the iPhone XS Max: DXOMARK gave this shooter a score of 118. If you add its telephoto lens, that will go up to 126**. You can check their review if you click here.

I hope this helps: you'd probably like to know that all of its rivals can record videos in 4K or more and have an ultra-wide-angle lens, and 93% feature Optical Image Stabilization. Although only 15% of them feature a macro lens.

Despite only having an optical zoom of 4x, thanks to its AI, the Galaxy S20 Ultra is also known for its impressive 100x hybrid Space Zoom. While better than a digital zoom, that's still far from a pure optical zoom.

About the Galaxy S20 Ultra: DXOMARK evaluated this camera, and here's the score: 128. And if we consider the telephoto and wide-angle lenses, that score goes up to 144. You can click here to check it out.

Furthermore, just to let you know, all of its rivals can record videos in 4 or 8K, have an ultra-wide-angle lens, and feature Optical Image Stabilization, and 76% feature a telephoto lens. Additionally, only 4% of them feature a macro lens.

We can classify the Galaxy S20 Ultra as a high-end.

**Consider this as an estimative, at least for phones with no zoom and up to 35 to 40MP. These guys recently updated their test protocol, and I need more reviewed devices to fine-tune older scores.

Who has the best frame?

They ended up with the same score, so don't worry too much.

The iPhone XS Max weighs 208 g. (7.34 oz), while its rival is 14 g. (0.55 oz) heavier. If you're curious, the "weight to display size" score of the iPhone XS Max is 3.2, which suggests it's kind of weighty for a 6.5 inches display. The Galaxy S20 Ultra, in its turn, has 3.1, which suggests it's considerably hefty too.

The iPhone XS Max truly is water-resistant. It can be submerged 1 to 3 meters deep, on par with the Galaxy S20 Ultra. That should be for up to 30 minutes, and it's in standby mode only. So don't take photos underwater.

Which has the best battery?

The iPhone XS Max does have a smaller battery, with 3174 mAh, while the Galaxy S20 Ultra has 5000 mAh. And by GSMArena's standards, the latter does have better battery life.

You may actually be considering it for this reason, but Samsung could've done much better, as other devices of this size have way better battery life. That's the conclusion that we take from its "battery to phone size" rate of 2.3. But the iPhone XS Max only achieved 2.1.

Fast charging is indeed fast with the Galaxy S20 Ultra. Its competitors usually sit at nearly 33w.

The Snapdragon 865 also has better battery efficiency (about 10% more screen-on-time) when you compare it to the Exynos 990.

Which has more storage?

The Galaxy S20 Ultra has about two times more storage.

Apple put 4GB of RAM and 64GB of built-in storage on the iPhone XS Max. Furthermore, other devices from this budget usually deliver more RAM and more storage. They average at 8GB of RAM and 135Gb of storage.

Neither storage nor RAM should be an issue on both phones. However, if you love to have or record tons of videos, 64 GB alone won't get you there.

Micro SD No microSDXC (shared SIM slot)

*Internal Storage + 256GB Memory Card (Max: 512GB).

Which is the most connectivity-friendly?

I'd go for the Galaxy S20 Ultra if you really value 5G.

If you love good-old wired headphones, you're out of luck because none of them included a 3.5mm headphone jack. You can buy an adapter, but the wireless buds are your only option. You can have it anyway if you're not really leaning towards any of these. You'd have to pick a smartphone like the Sony Xperia 1 II.

The Galaxy S20 Ultra has two network variants: LTE or (LTE and) 5G.

Want to know about that global score? But first, let's see where its rivals are. It's 7.0 for the iPhone XS Max and 7.2 for the Galaxy S20 Ultra.

Verdict: What Makes the Samsung Galaxy S20 Ultra Stand Out?

If you're in for an upgrade, don't expect a performance bump. Instead, you'll be getting way more quality and flexibility when taking your photos.

You'll also be getting a considerable improvement in display and battery life, but to some, maybe the main reason is in the storage department. 128GB plus a MicroSD card slot seems too good to be true, and I'm not even mentioning the extra 8GB of RAM (or am I?).

"Display size to phone weight" ratio explained

This indeed is a "display size to phone weight" ratio, but because every phone ended up somewhere between 0.0272 and 0.0421, I've amplified (adapted) those values so they would fit in a 0-10 scale. As of now, the best smartphone is the Samsung Galaxy A40, with 140g. (4.94 oz) for a 5.9 inch display. It got a score of 9.92. While the worse device is the iPhone 8 Plus, which weighs 202 g. (7.13 oz) and has a 5.5-inch display. It ended up with a score of 0.75.

Please, be aware that this score is subject to change if and when a new smartphone comes along that ends up being outside of this scale.


"Battery to device size" ratio explained

This score should give you an idea about the energy footprint of the devices you're considering. It reflects not only the hardware and the energy that it requires but also the amount of energy that the battery can deliver.

The major spenders on any device should be the display and the SoC. But everything from a notification led to its modems need to be optimized, or else, the OEM should simply include a bigger battery as a compensation. Unfortunately, it isn't always possible due to size limitations. But in the end, if a particular OEM can do a good job and give you excellent battery life on a small device, so should everyone else. That's why I've added a "battery to device size" ratio. But since the real scale went from 119 (for the Galaxy S10e, Snapdragon variant) and up to 164 (for the iPhone 7 Plus), I've decided to convert them so they would fit in a 0-10 scale, being 0 the worst device, (the iPhone 7 Plus) and 10 the one every OEM should look up to.

As an example, Apple did an excellent job on the iPhone 7. It has a score of 8. Despite having a small capacity, the hardware is well optimized, and it still gives you decent battery life considering its size. The iPhone 7 Plus, on the other hand, with those bezels shrinking its display size, clearly could've been the #1 in our top 10 list of best battery devices if Apple simply filled all that empty space with a bigger battery.

As a side note: I haven't included the dept of the devices in this formula because even if a device ended up being 1mm/0.03 inches thicker, it wouldn't matter that much to those who really value battery life.

Please, be aware that this score is subject to change if and when a new smartphone comes along that ends up being outside of this scale.



As of now, these are the rivals that were considered for each of them. They may change every time its prices are updated.

These are the lowest prices found on Amazon, eBay, BestBuy, and Walmart.

Formula deviation

Since the guys at DxoMark don't review every camera out there, I've come up with a formula based on the ones that they do rate, so I could get an equivalent score for the ones they don't review. After testing it against these cameras, I got the deviation between that and their DxO score.

Device: DxOScore Deviation
Samsung Galaxy A50: 88 -1
Apple iPhone XR: 104 1
Xiaomi Mi 9T Pro: 108 -7
Xiaomi Redmi Note 8 Pro: 87 1
Sony Xperia 1: 99 -1
Sony Xperia 5: 101 1
Samsung Galaxy Note 8: 100 0
Samsung Galaxy Note 10 Plus: 126 2
Apple iPhone 8 Plus: 96 -3
Xiaomi Pocophone F1: 92 -1
Apple iPhone 7 Plus: 90 -1
Apple iPhone X: 101 3
Apple iPhone 11: 112 -1
Samsung Galaxy Note 8: 100 0
Samsung Galaxy Note 9: 107 1
Apple iPhone XS Max: 110 -2
Apple iPhone 11 Pro Max: 124 1
Samsung Galaxy S10: 124 2
Apple iPhone XS: 110 -1
Samsung Galaxy S10 Plus: 120 -2
OnePlus 7 Pro: 122 0
OnePlus 7T Pro: 122 0
Huawei P30 Pro: 125 -1
Google Pixel 4: 117 0
Google Pixel 3: 103 0
Google Pixel 2: 100 0
Samsung Galaxy S20 Plus: 127 -2
Samsung Galaxy S20 Ultra: 132 2
OnePlus 6: 100 0
OnePlus 6T: 101 1
Samsung Galaxy S9 Plus: 105 -1
Huawei Mate 20 Pro: 120 0
Xiaomi Mi 9: 115 0
Huawei Mate 30 Pro: 132 0
Huawei P40 Pro: 140 -1
Apple iPhone SE 2: 101 0
OnePlus 8 Pro: 126 0
Xiaomi Mi 8: 105 1
Samsung Galaxy A71: 89 1
Xiaomi Mi 10 Pro: 134 0

As you can see, most cameras sit between 1 and -1, while a few of them go up to 2 or -2. That means it's reasonable to assume other similar cameras that they don't review to, in the worst-case scenario, be anywhere from -2 to 2 points from the score that the formula gets.

For example: Given that the Pixel 4 got 117 points and that the Pixel 4 XL share the same year and camera specs, it's reasonable to expect a score of 117 too. But in reality, if they do review that camera, it may end up anywhere between 115 and 119.

Be aware that at DxO, they give a score based on their opinion, not based on any formula. That's why I think there's an odd difference of 6 points between the iPhone 8 Plus and the iPhone X. In theory, they should have the same camera.

I'm guessing that the Mi 9T Pro got a deviation of 7 points because they tested its Chinese variant (the K20 Pro).

Update: They just changed their protocol to include preview image evaluation and trustability. I'm keeping the old table (for now) for reference purposes, and I'll be adding a new one as soon as they review at least a couple of new mclass-range cameras.

You can expect the same (or a bit bigger) deviation for high-end cameras, but anything with a score below 100-110 should be taken with a grain of salt.

This is valid for all cameras tested with the previous protocol. For those that they dclassn't test, the deviation may be up to twice as much.
