OnePlus Nord vs Samsung Galaxy S21: Which to Pick?

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

The Galaxy S21 isn't that affordable, but it also is the better device of the two considering their specs.

It has better performance (+59%), better glass protection, a better display, and water-resistance. But with the Nord, you can get a glass back and better battery life.

What else do they have to offer?

The Galaxy S21 also gives you a higher refresh rate display, wireless charging, and reverse wireless charging. But the Nord also brings a larger (+0.2") display and Bluetooth 5.1.

How much more will the Galaxy S21 cost me?

If you ignore carrier offers, you'll have to spend approximately $388 more.

Is the Nord still worth getting in 2021?

Sure, you can look for other devices, but the Nord is an outstanding handset even in 2021. Sure there are other devices like the Apple iPhone 11 Pro Max, but we should praise it because it features good cameras, good battery life, tons of storage, and fast charging.

Be aware that the Nord's picture quality is, on average, 35 points above other cameras from its price range. But you won't find a winner here.

About the Nord: DXOMARK gave this shooter a score of 117. Then, if you consider its digital zoom abilities, you'll end up with a score of 126. For an in-depth review, click here.

PS: 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.

About the Galaxy S21: On DXOMARK's reviewing article, they gave this shooter 123 points. And if we consider its wide-angle lens, we get a score of 137 points. If you want to know more about every tidbit, check it here.

Last (but not least), if you must know, just like the other device, all of its rivals can record videos in 4 or 8K, have an ultra-wide-angle lens, and feature Optical Image Stabilization. Regardless, only 14% of them feature a macro lens.

We can classify the Nord as a lower high-end and the Galaxy S21 in the high-end ballpark.

Have you noticed yet? If you want a telephoto lens, none of these will help you. Just pick something like the Galaxy Note 10 or the Google Pixel 4 XL instead. Or just forget them because devices like the Oppo Find X2 Pro aren't too good to be true anymore.

Who has the best frame?

I'd go for the Galaxy S21 for its weight, the number of color options, and water resistance.

The Nord is 15 g. (0.53 oz) heavier than its rival, which sits at 169 g. (5.96 oz). But because screen size also matters, I've come up with an adapted "display size to phone weight ratio" score. The Nord got 5.4, which means it has an acceptable score for a 6.4 inches screen. In the meantime, the Galaxy S21 has 6.6, which is pretty nice.

You can drop the Galaxy S21 into the water, up to 1 to 3 meters deep. That shouldn't last over half an hour, and it's in standby mode only. So don't take photos underwater.

Which has the best battery?

The Nord does have a bigger battery, with 4115 mAh, while the Galaxy S21 only has 4000 mAh. And GSMArena did test them out, and the former does have better battery life.

If you fancy quick charges, you can count on the Nord. Devices with similar prices rarely exceed 26 watts.

Which is the most connectivity-friendly?

The Nord is your better option, as it features Bluetooth 5.1.

About the 3.5mm jack: Now may be the time to consider moving to wireless earbuds. Want a piece of advice? Forget about adapters and go for the wireless buds. You can have it anyway if you're not really leaning towards any of these. You can get that with the Oppo Find X3 Lite.

Both have a single network variant: (LTE and) 5G.

"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.

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

Samsung Galaxy Note 8: 100 0
Samsung Galaxy Note 10 Plus: 126 2

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

Samsung Galaxy S20 Plus: 127 -2
Samsung Galaxy S20 Ultra: 132 2
OnePlus 6: 100 0

Samsung Galaxy S9 Plus: 105 -1
Huawei Mate 20 Pro: 120 0
Xiaomi Mi 9: 115 0

Huawei P40 Pro: 140 -1
Apple iPhone SE 2: 101 0

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.
