Xiaomi 12X vs POCO F3: which phone to buy? See comparatives


Xiaomi 12X and POCO F3 are two excellent phones that we have already tried here. And in the last video I made about the 12X, a question appeared in the comments: which one to buy? And that’s why I decided to record this video.

Both are premium mid-range cell phones, they draw a lot of attention at the time of purchase.

Both bring the processor Snapdragon 870which delivers great value for money, even compared to the best cell phones on the market.

Because, speaking of price, proportionally, the better the cell phone, the more you have to pay for the feature placed, since fewer people will buy the product and the more difficult it is for the company to offer that specification. We pay a lot more to get access to the best resources in the world.

So this premium mid-range segment is really worth it, it’s the balance of features offered and price.

This post takes into account cell phones being imported, such as on Chinese marketplace sites like AliExpress, which you buy directly from China and are sent here to Brazil to your home.

But then, which is the best? Which one to buy?

Here I list some details of each one and help you make your choice comparing point by point.

Xiaomi 12X and POCO F3

First, it is important to understand Xiaomi’s brand division and the proposal of each device.

The Xiaomi 12X is a 12 family cell phone, it is the simplest of the line. From worst to best we have: Xiaomi 12X, 12 and 12Pro. So I highlight here that it is part of the main Xiaomi smartphone family. The main line that receives special care by the Chinese manufacturer is where it puts its best.

The POCO F3, on the other hand, is from Xiaomi’s POCO sub-brand, which focuses on bringing cost-effectiveness. In them there are features that border on a top of the line but don’t bring all the care of the main line. So the POCO F3, even with a lot of performance, is still slightly inferior to the Xiaomi 12X in some details.

The Xiaomi 12X was released close recently at the time of writing this post. So it has a much higher price at this time of release. Cell phones tend to drop in price a lot over time. So my considerations took into account the decrease in prices of the Xiaomi 12X.

First, the design

The Xiaomi 12X is smaller, the POCO F3’s screen is 6.67”, while the Xiaomi 12X is 6.28”. This gives a very different look to each one. Do you prefer larger cell phones? So the 12X might seem pretty small to you. Otherwise, the 12X can be very interesting, conveying an idea of ​​a minimalist.

To watch content, you may end up choosing a larger screen, which can also be interesting to play.

Anyway, the construction of both devices is interesting. The Xiaomi 12X features Gorilla Glass Victus protection, the best protection on the market against scratches and drops. POCO brings Gorilla Glass 5, which is a great protection and just not the best on the market.

So here this issue of difference between the main and secondary lines starts to become evident. For the main brand, which carries the company’s name, it takes more care and affection in its choices, while the secondary brand can experiment, risk price margins, get cuts in some specifications and so on.

The POCO F3 brings the fingerprint reader on the sides along with the on/off button, while the 12X brings the reader on the screen. This changes the body of the phone and brings a more premium look to the flagship smartphone.


The Xiaomi 12X’s screen is smaller, but not by much. And also better, but not by much. You can compare and see the difference between the screen specs below. Note that the differences are really few and not so significant.

– 6.28″ AMOLED DotDisplay
– Refresh rate: 120Hz
– 1100 nits
– Color gamut: DCI-P3
– HDR10+

– DisplayMate A+
– Touch sampling rate: up to 480Hz

– Refresh rate: 120Hz

The question that starts to become evident here is whether you are willing to pay more to have the few extra features of the Xiaomi 12X.

Here, too, it is evident that there are not so many differences in extra features between the devices. The highlight is even the Xiaomi 12X’s 67W charging and the absence of the standard headphone jack on the flagship model. There is also a difference in the location of the fingerprint reader, on the screen on the more expensive device.

Here it depends on your preference, although the on-screen fingerprint reader is a more difficult feature to implement. Also the headphone issue is quite particular, but I know it’s a game changer.

The battery present in cell phones has minimal difference, more precisely 20mAh. So the performance of the two in autonomy is similar, about a day and a half of moderate use. It hardly lasts two days away from the outlet, especially if you play a little game or enjoy watching videos.

Xiaomi 12X: 4500mAh
POCO F3: 4520mAh


You can check out photos taken with each one in the POCO F3 review here on the website and also in the post about the Xiaomi 12X. Both deliver excellent photos, especially the macro. It was even with the POCO F3 that I realized the value of a good macro, when comparing its camera with that of other cell phones.

It’s a very interesting set of cameras and you won’t be disappointed. Here, the Xiaomi phone does a little better, including the selfie, which is 32MP.

The performance is technically the same, the difference should not even be considered, as by repeating the test the positions change. There’s plenty of performance for browsing activities as well as gaming. It is possible to run all PlayStore games without problem and with excellent quality. The difference to a top of the line is that you can trust that you can put all the graphics to the maximum.

Conclusion and a small detail

Despite being an excellent phone, the POCO F3 has a small batch issue where its proximity sensor fails. This is noticeable when playing an audio on some social network or using the speakerphone. Unfortunately there is nothing you can do, either you get a POCO F3 with this problem or you are lucky not to suffer from it.

It’s something that doesn’t bother everyone, but it’s an existing issue that should be taken into consideration before purchasing. Do you mind taking that risk?

Other than that, it’s worth taking a good look at the prices and analyzing the differences mentioned in this post. So, which one do you prefer?
