Huawei P40 vs Samsung Galaxy S21: Is The P40 Good Enough?

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

The Galaxy S21 is a little bit more expensive, but it also has better specs.

It gives you better glass protection, a better display, and Google's services. But the P40 brings a glass back, better battery life, and external storage.

What else do they have to offer?

With the Galaxy S21, you'll also get a higher refresh rate display, better peak brightness, wireless charging, reverse wireless charging, and more RAM (8GB vs. 6GB). But with the P40, you can also get a telephoto lens (+51 mm) and Bluetooth 5.1.

How much more will the Galaxy S21 cost me?

If you're not considering going for a carrier subscription, it'll cost you around $132 more.

Is it still worth buying the P40 in 2021?

The Huawei P40 isn't the most cutting-edge device in 2021, but it's still a powerful phone. Sure, you can take a peek at other devices like the Apple iPhone 12, but we should acknowledge this device, as it has good performance, good cameras, good battery life, and optical zoom.

Just keep reading if you want to know everything about them, how they stack up against their rivals, and how the industry is scoring their specs.

We can label both of them as high-end.

Some users did install the Google Play Store on recent Huawei phones, but please be aware that officially you won't get Google apps, and some essential apps may be missing too on the P40.

Who has the best frame?

There isn't a clear winner, so don't worry too much.

The Galaxy S21 weighs 169 g. (5.96 oz), while the other is 6 g. (0.21 oz) heavier. If you want a big screen in a lightweight phone, I've developed a formula for a kind of "display size to phone weight" ratio. The P40 got a score of 5.4, which means it has an acceptable score for a 6.1 inches screen. Having said that, the Galaxy S21 has 6.6, which is pretty nice.

The P40 is rated IP68, which means it's water-resistant in up to 1 to 3 meters, on par with the Galaxy S21. Remember that it shouldn't be for over half an hour, and it's in standby mode only. So don't take photos underwater.

The P40 features a 3800 mAh battery, while the Galaxy S21 has 4000 mAh. But by GSMArena's standards, the former is the winner here.

Which is the most connectivity-friendly?

The P40 is your better option, as it features Bluetooth 5.1.

If you got used to counting on the good-old 3.5mm headphone jack, forget about it. Want a piece of advice? Forget about adapters and go for the wireless buds. Luckily, you can still get it on other phones if you don't mind searching for them. Perhaps you don't mind settling with the Sony Xperia 1 II.

These two are (LTE and) 5G compatible.

Are you also considering other options? The global score can help. For reference purposes, I'll tell you where most of its rivals average. It's 7.0 for any of them.

Verdict: What Makes the Samsung Galaxy S21 Stand Out?

Well, I do like the P40, don't get me wrong, but Huawei is just at a bad place right now, without Google's services on their devices. That should be a deal-breaker. If not, you also won't get decent glass protection and Huawei has no one else but itself to blame. Still, the P40 does have a nice telephoto lens, a great battery life, nice looks, and external storage.

But the Galaxy S21 has a better display with better peak brightness, higher refresh rates, and better glass protection. Not only that, but it also has wireless and reverse wireless charging, plus 2 extra GB of RAM.

"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.

These are the lowest prices found on Amazon, eBay, BestBuy, and Walmart.

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

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

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.
