Which Phone Has The Best Cameras?

We can safely assume that the Samsung Galaxy S21 Plus has a better shooter.

About the Galaxy S21 Plus: This camera came out of DXOMARK's labs with a score of 123. If you add its wide-angle lens, you'll end up with a score of 137. For a thorough review, click here.

I hope this helps: you should 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. On the other hand, only 15% of them feature a macro lens.

About the Galaxy A72: Sooner than later, we'll be getting a review from DXOMARK's team. Given its specs, it'll be close to 101*. And if we consider the telephoto and wide-angle lenses, we end up with a score of 115** points.

Last (but not least), just so you know, all of its rivals can record videos in 4 or 8K and have an ultra-wide-angle lens.

If you prefer, we can grade the Galaxy S21 Plus as a high-end while the Galaxy A72 leans towards the upper mid-range.

*The guys over at DXOMARK know how to benchmark these shooters. Too bad some cameras don't have a chance to be tested. So when I get my hands on one of them, I do my best to get a comparable score by evaluating hardware specs only (sensor size, Aperture, HDR, OIS, Lenses, and so on). The last time I've checked this formula, some cameras had a deviation of up to 2 points.

**This score still needs improvement, especially for cameras with no zoom and with less than 40MP. They just changed their protocol, and they don't have enough reviews, so I can refine the pre-update camera scores.

Who has the best frame?

The Galaxy S21 Plus does win some points here, mainly for its glass build, water resistance, and better looks.

In addition to that, the Galaxy A72 is around 12% bigger than other devices at this price level.

Both also have about the same weight: 200 g. (7.05 oz). If you want a big screen in a lightweight phone, I've come up with an adapted "display size to phone weight ratio" score. The Galaxy S21 Plus got 4.6, showing it has an acceptable score for its screen size. Having said that, the Galaxy A72 has 4.3, so nothing to state here.

You can drop the Galaxy S21 Plus into the water, up to 1 to 3 meters deep, but the Galaxy A72 should hold up to 1 meter. That should be for up to 30 minutes, and it's freshwater in standby mode only.

"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

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

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.
