Xiaomi Mi 10 vs Samsung Galaxy S21 Plus: Which to Pick?

author Luis Silva (February 2021 Updated: March 2022 - 6 min. reading time)

The Galaxy S21 Plus will cost you more, but it also is the better device of the two considering their specs.

It features better glass protection, a better display, water-resistance, and more OS updates (3 additional years).

Are there other things worth mentioning?

The Galaxy S21 Plus also comes with a higher refresh rate display. But the Mi 10 will give you faster wireless charging (30w vs. 15w) and Bluetooth 5.1.

How much more are you willing to spend on the Galaxy S21 Plus?

If you're going off-contract, you'll have to invest an additional amount close to $470.

Is it worth buying the Mi 10 in 2022?

Sure, you can look for other devices, but the Mi 10 is an outstanding handset even in 2022. Sure there are other devices like the OnePlus 9, but this one does have good performance, good battery life, fast wireless charging, and 8K recordings.

Is it worth buying the Galaxy S21 Plus in 2022?

Don't let its age scare you. The Galaxy S21 Plus still is a fantastic device as we go thru 2022. Its overall score hasn't dropped much yet, mainly because of its good performance, good battery life, excellent glass protection, and 8K recordings. But don't just ignore the Apple iPhone 11 Pro Max.

Which Phone Has The Best Cameras?

The Xiaomi Mi 10 should have an overall better camera.

About the Mi 10: I'm counting on DXOMARK to review this camera, and by its specs, I bet it'll get close to 131* points. If you also consider its wide-angle lens, you'll end up with a score of 144**.

PS: you should know that all of its rivals can record videos in 4K or more and have an ultra-wide-angle lens, and 88% feature Optical Image Stabilization. However, only 16% of them feature a macro lens.

About the Galaxy S21 Plus: DXOMARK has rated this camera with a score of 123. Plus, combining with its wide-angle lens, we get a score of 137 points. For an out-and-out review, check their article.

Furthermore, all of its rivals can record videos in 4 or 8K and have an ultra-wide-angle lens, and 92% feature Optical Image Stabilization. Regardless, only 20% of them feature a macro lens.

If you prefer, we can grade these two as high-end.

Have you noticed yet? If you want a telephoto lens, you better wrap it up and start looking for other devices like the OnePlus 9 Pro. But that won't fully satisfy you either because cellphones like the Galaxy S20 Ultra aren't too good to be true anymore.

*DXOMARK is a well-known market reference when it comes to camera benchmarking. Too bad they don't get a chance to test most of the cameras out there. So what do I do? I do my best to get a comparable score by evaluating hardware specs only (sensor size, Aperture, HDR, OIS, Lenses, and so on). This score should have a 2 points (more or less) error threshold.

**Please take this with a grain of salt, particularly on mid-end cameras with less than 40MP and no zoom lens. These guys recently updated their test protocol, and I need more reviewed devices to fine-tune older scores.

Who has the best frame?

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

The Mi 10 is 8 g. (0.28 oz) heavier than the other, weighing about 200 g. (7.05 oz). But because screen size also matters, the "weight to display size" score of the Mi 10 is 3.5, which means it's kind of weighty for a 6.6 inches screen. The Galaxy S21 Plus, in its turn, has 4.6, so nothing to state here.

The Galaxy S21 Plus is rated IP68, which means it's water-resistant in up to 1 to 3 meters. 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?

In theory, they should have about the same battery life because they have the same capacity: about 4780 mAh. And as reported by GSMArena, you shouldn't expect notable differences here.

For the record, both of them also don't have many rivals at any given price range. Do check our best-of listing.

Mi 10's Quick wireless charging is likewise snappy. That's uncommon in its class.

Which is the most connectivity-friendly?

You can only get Bluetooth 5.1 with the Mi 10.

Do you still favor wired headphones? None of them will help you with that. Want a piece of advice? Forget about adapters and go for the wireless buds. There also are other options out there if you're not really leaning towards any of these. Perhaps you don't mind settling with the Galaxy Note 10 Lite.

They both run on (LTE and) 5G networks.

"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.

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 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.
