If you're considering a new and unlocked smartphone, you're going to shell out an extra amount of about $116.

Who has the best frame?

The Pixel 5 does win some points here, mainly for its weight, aluminum back, and better looks.

By doing some math, I found out that the Pixel 5 is 12% smaller than most similarly priced devices.

The Pixel 5 weighs 151 g. (5.33 oz), while the other is 18 g. (0.71 oz) heavier. But because this is a bit relative, I've developed a formula for a kind of "display size to phone weight" ratio. The Pixel 5 got a score of 8.4, showing it's one of the lightest phones for its screen size. The Galaxy S21, in its turn, has 6.6, which is pretty nice.

You can drop the Pixel 5 into the water, up to 1 to 3 meters deep, just like the Galaxy S21. Remember that it shouldn't be for over half an hour, on standby, and freshwater only.

Which has the best battery?

In theory, they should have about the same battery life because they have the same capacity: about 4080 mAh. And as reported by GSMArena, both should theoretically get the same battery life.

Battery life on the Pixel 5 isn't anything to write home about, but Google put some effort into making an overall battery saver device. That's what a "battery to smartphone size" rate of 7.9 shows.

Which is the most connectivity-friendly?

These two do look alike sometimes.

About the 3.5mm jack: Now may be the time to consider moving to wireless earbuds. You can buy an adapter, but the wireless buds are your only option. You can also check other devices if you're not really leaning towards any of these. You'd have to pick a smartphone like the Galaxy S10 or the Oppo Find X3 Lite.

These two are (LTE and) 5G compatible.

Want to know about that global score? Let me point out the average of its competitors. It's 6.9 for the Pixel 5 and 7.0 for the Galaxy S21.

Verdict: What Makes the Samsung Galaxy S21 Stand Out?

You should've noticed by now that Google is no longer trying to compete with other flagship devices. The Pixel 5 is more like a premium mid-range with below-average performance. But at least you'll get a cleaner user interface.

But if you're willing to spend a bit more, the Galaxy S21 will get you so much better performance, higher refresh rates, and a better display.

Although if you want the best bang for your buck, you should consider the OnePlus 8 Pro or the Galaxy S20 FE 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
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.
