Motorola Razr 40 Ultra Review | The foldable phone with a useful external screen

The Motorola Razr 40 Ultra is Motorola’s new foldable cell phone option, and it arrives in the Brazilian market to compete directly with the Galaxy Z Flip 4. The compact folding model brings top-of-the-line configurations in its housing in a revamped design.

In addition, there are important improvements in the size of the external screen, as well as the functions built into it to ensure high usability. In this way, this display allows the smartphone to be quite usable even closed.

In conjunction with this, the cameras promise an image quality superior to that of competitors. But is all this really applied in practice? Check out my opinion in the full review.

Flip design with a touch of nostalgia

Physically, the Razr 40 Ultra is very light, its structure demonstrates that it follows what the premium segment demands in a cell phone. Its body is all in Gorilla Glass Victus, its sides in aluminum, and the hinges in stainless steel.

Even with all these physical differentials, Motorola was wrong in not implementing IPX8 certification in its foldable. The presence of IP52 only protects it from dust and splashes of water, something that limits the experience and leaves it below the Flip 3 and 4 in this regard.

The malleability of the folding reminds me a lot of the Flip 3, as it has resistance, but without as much rigidity as the Flip 4. However, I felt that the cell phone is a little more “soft” horizontally when it is closed. For example, I can move it around and hear the noise of its case, something that doesn’t happen with Samsung’s foldables.

In my opinion, there are at least two explanations for this. The first is the “bridge syndrome”, in which the structure is more malleable to better adapt to users and avoid breaking the hinges. The second, and which worries me, is a construction flaw that could lead to physical problems in the short term. Unfortunately, these are just hypotheses, and none of them can be proved at the moment.

It is worth mentioning that the Razr 40 Ultra has the mode flex view, which allows the adaptation of some applications to work in a way that is adjusted to the use of the cell phone at a 90-degree angle. However, it is still necessary for Motorola to strengthen its partnership with app developers, as Samsung did, so that users can enjoy more of this responsiveness.

Finally a big and useful external screen

The biggest highlight of the Motorola Razr 40 Ultra is, without a doubt, its external screen. The 3.6-inch display with a 144Hz refresh rate delivers more fluidity than many large displays. By filling much of the frontal area when it is folded, Motorola took the opportunity to give useful functions to the AMOLED panel.

In this way, it is possible to use several applications, such as Google Chrome, Google Maps, photograph and even play without opening the smartphone. In the foldable cell phone’s interface, it is possible to manage which contents will be displayed on the external screen, as well as change the background and the clock face that appears when the display is locked.

The internal screen is a 6.9-inch AMOLED with a frequency of 165 Hz. For my taste, the brightness is high and the saturation level pleasant, making the displayed information not need more than 50% of the total illumination to be visible in different light conditions.

Motorola’s top-of-the-line foldable

The Razr 40 Ultra features the Snapdragon 8+ Gen 1 chipset, a Qualcomm platform widely used in 2022 gamer phones. In addition, the chipset is present in the Galaxy Z Flip 4, which is the only competitor of the new smartphone here in Brazil for now.

Motorola offers here in the country the unit with 8 GB of RAM and 256 GB of internal space. By bringing these settings, it is possible to run any application or game smoothly on the device, without any kind of hiccups or crashes that could influence the experience.

In addition, the presence of My UX based on Android 13 guarantees exclusive features to enhance the usability of the foldable. For this reason, there is a separate menu in the settings area for the external display only.

Result in AnTuTu

In our performance tests run on the AnTuTu app, the Razr 40 Ultra scored 1,079,979 points. This result left it slightly below the 1,097,064 achieved by the Poco F5, which has the Snapdragon 7+ Gen1.

Based on this result, we see that Qualcomm’s platforms are performing very closely in benchmarks. However, in practical use, the foldable is superior in everything it proposes.


One of the biggest defects of foldable cell phones is the camera far below normal flagships, but Motorola goes against that with the Razr 40 Ultra. The 12 MP main sensor provides pleasant capture results, and the same goes for the 13 MP hybrid ultrawide.

The level of color accuracy surprised me on this phone, because the level of sharpness and texture in colors is great. With it, you can have the instagrammable experience that many foldable users want on a daily basis.

The 32 MP front camera manages to deliver an excellent level of sharpness in different light conditions. Something very interesting is that it manages to adjust the white balance to provide photos with the level of coloring equivalent to what is expected.

For video recording, both the front and rear camera can be used with the maximum resolution of 4K at 60 fps, and that is a big plus point. Videos are stable and fluid. Also, the horizontal stabilization feature is present for the rear camera, but I don’t like to use it because the sharpness drops along with the resolution, and its function makes no difference to the general public.

Sound system

The Razr 40 Ultra’s sound is stereo, and of good quality. The volume is within the expected average, I don’t feel distortions when it’s at maximum volume, and the reverb manages to be fluid, despite the little internal space for the speakers.

As a negative point, I can say that the lack of subbass is something that bothers me, but I won’t miss it on a daily basis by using headphones. With this accessory, the presence of Dolby Atmos helps elevate the experience and ensures full-bodied sound.

battery and charging

Regarding the battery, the Razr 40 Ultra has a capacity of 3,800 mAh. As a result, the device consumed 38% in the Canaltech usage test, which consists of 6 hours of browsing alternating between social networks, games and video applications.

Based on that number, Motorola’s foldable can be used for up to 15 hours before shutting down. This makes it slightly above the Galaxy S23 in autonomy, demonstrating that the result is surprising for a smartphone with a flexible screen.

Regarding the charging process, in the device’s packaging, the brand already provides a 30 W charger. In this way, it is possible to exploit all the charging power present in the device, which takes, on average, 1 hour and 20 minutes to leave from 0% to 100%.

direct competitor

As I have mentioned a few times throughout the text, the Galaxy Z Flip 4 is the direct competitor of the Razr 40 Ultra here in Brazil. As it is the only foldable to compete with the American model in the country, Samsung brings elements that provide equivalence and others that are below.

In terms of screen, the South Korean’s external display is smaller and has fewer built-in functions that could allow independent use. Its physical structure, however, is more rigid than Motorola’s foldable.

In addition, the Flip 4 is IPX8 certified, allowing you to submerge it in fresh water for a few minutes. On the other hand, the internal screen is Dynamic AMOLED 2X at 120 Hz, below the Motorola model.

The cameras are also a little lower in well-lit environments, but Samsung still comes out ahead in dark mode. Regarding the price, the Flip 4 has been on the market for almost a year, but it arrived in Brazil for R$6,999, a thousand reais less than the R$7,999 charged by Motorola for the Razr 40 Ultra.

Is the Razr 40 Ultra worth buying?

The Motorola Razr 40 Ultra is a great cell phone. Although its hardware is considered “outdated” for bringing a 2022 chipset, the device remains excellent. Performance does not disappoint in continuous use.

The battery has a great energy balance. As a result, it is possible to obtain good hours of use for the consumption of different content formats, approaching top-of-the-line bar-shaped models.

Another highlight of this cell phone is its construction, which conveys the confidence that previous generations lacked. In addition, the external screen working almost independently demonstrates that the optimizations in the system were well executed.

However, the price may still be a limiting factor for the public at this first moment. After all, the Razr 40 Ultra arrives in Brazil for BRL 7,999, while the Galaxy Flip 4 was announced for BRL 6,999 almost a year ago, and its price has not dropped much on Samsung’s official website since then.

Therefore, everything will depend on how much Motorola will reduce the value in the coming months to ensure that the public is interested in the smartphone, even after the announcement of the Flip 5 here.
