Which One Has The Best Performance?

Performance-wise, Geekbench 5 scores the Galaxy A42 21% ahead in the multi-core ranking. The differences are slight but still noteworthy between these two chipsets.

Unfortunately, the Galaxy A52 isn't that smooth. It actually is below the average by comparing it with other smartphones from this price range. While they got a score of about 2242, it has 1577. That puts it 42% below them.

By the way, you can define the Galaxy A42 as an upper mid-range and the Galaxy A52 as mid-range.

The Galaxy A52 has a better display, and it wins by a significant margin.

One peculiarity that the Galaxy A42 has over most smartphones in its class: Its display has a low pixel density.

Considering the Galaxy A42, just know that 81% of its rivals have an AMOLED screen. But only 15% of them feature Gorilla Glass 6 or Victus.

For the Galaxy A52, I should say that 84% of its rivals can play HDR content, 94% have an AMOLED screen, and 81% have an Always-On display. Then again, only 23% of them feature Gorilla Glass 6 or Victus.

Which Phone Has The Best Cameras?

We can safely assume that the Samsung Galaxy A52 has a better shooter.

About the Galaxy A42: I'm expecting a review from DXOMARK anytime now, and I'm also expecting a score pretty close to 79*. By including its wide-angle lens, the final score goes up to 91** points.

PS: you should know that 85% of its rivals can record videos in 4K or more, and all have an ultra-wide-angle lens. On the other hand, only 19% of them come with a telephoto lens.

About the Galaxy A52: DXOMARK's gurus gave this shooter a score of 107. By considering its wide-angle lens, we'll get to the final score of 117 points. For an out-and-out review, check their article.

PS: This Dxo score is for the 5G version, but this version should be close enough.

Winding it up, just to let you know, all of its rivals can record videos in 4 or 8K and have an ultra-wide-angle lens. Regardless, only 23% of them feature a macro lens.

If you prefer, we can grade the Galaxy A42 as mid-range and the Galaxy A52 more as an upper mid-range.

Have you noticed yet? If you want a telephoto lens, just ignore these two and check the Galaxy S20 FE or the Oppo Find X2 Neo instead.

*DXOMARK knows how to test these shooters out. Too bad some cameras don't have a chance to be tested. So whenever I come across one such camera, I try to do my best by giving a similar score based on hardware specs only (OIS, Sensor size, Aperture, Lenses, HDR, and so on). Our lastest test on our formula showed a topmost discrepancy of 2 points.

**Please take this with a grain of salt, at least for phones with no zoom and up to 35 to 40MP. They just changed their protocol, and there aren't enough reviewed phones to extrapolate a backward-compatible score.

So, what about that global score? We'll get there. First, let me mention the average at their price range. They're at 5.7 (for the Galaxy A42) and 6.2 (for the Galaxy A52).

Verdict: What Makes the Samsung Galaxy A52 Stand Out?

If you want better performance and better battery life, then forget the Galaxy A52. Its cheaper sibling should be your option.

But the A52 can give you a higher peak brightness, higher refresh rates, better overall Always-on display, with much more DPIs.

Not only that, but its cameras also have Optical Image Stabilization, and it does charge faster: 25w vs. 15w.

The A52 is a bit slow, but if you're a power user and have access to a power outlet during the day, then this is a no-brainer.

"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
Sony Xperia 5: 101 1
Samsung Galaxy Note 8: 100 0
Samsung Galaxy Note 10 Plus: 126 2
Apple iPhone 8 Plus: 96 -3

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.
