Zendure SuperBase V/5 solar battery : review / opinion

---

Published on: 05-04-2025 / Modified: 05-04-2025
The POCO range was originally quite simple, with just one or two models. The range was gradually extended to cover all market segments, with the F range corresponding to the top end of the market. From a technical point of view, the F range could easily compete with top-of-the-range models from other brands. In terms of finish, however, this was not the case until the arrival of the POCO F6 Pro last year. With the POCO F7 Pro, the brand has literally hit the nail on the head. From a technical point of view, it takes performance to a new level, not to mention the finish, which also takes it to a new level. This new POCO doesn't resemble the previous generation or any other POCO, but that's okay, the result is pretty good

Will this new POCO F7 Pro become the new king of the price/performance ratio? Let's find out in this test!

Structure of my tests

I test the phones according to a pre-established structure (see below) to provide you with as much information as possible. Unfortunately, this takes a long time. Some tests like network performance tests take several days and for photo tests I sometimes have to wait until the weather is suitable to take pictures in good conditions. I am therefore obliged to publish the tests step by step, so I invite you to come back if the test is not complete at the time of your visit.

Price POCO F7 Pro

The list below shows the prices for the POCO F7 Pro from more than 50 sites around the world. If you are not satisfied with any price, you can subscribe to a price alert to be the first to be notified when the price drops.

Timeline

March 2025: POCO F7 Pro received prior to launch. Launch date scheduled for the end of March.

Unpacking

The latest Xiaomi phones I've tested were the first to come without a charger. POCO has not yet made this choice, at least not for the F range. The box contains a protective shell, a charging cable and a 90-watt charger.

Finish

The POCO F6 Pro I tested last year had already taken a big step towards a more polished finish. POCO had always neglected this aspect. With the F7 Pro, they've gone one step further, with a fairly classic design that's elegant and sober



This time, the photo block on the rear is circular. POCO changes its design almost every generation. The level of finish is much better here, and the various sensors are less conspicuous. They're all protected by the metal ring, which wasn't the case with the previous model.

The flash is separate and nicely integrated into the back of the phone.



The back is made of different materials mixing aluminum, polycarbonate and probably glass. I didn't get the info when I tested this phone, so I could be wrong. In any case, the overall look is very attractive. It's a far cry from POCO's previous generations



The perimeter is probably made of aluminum. This metallic textured effect gives it a more premium look, and it's cooler to the touch than the usual plastic

The ignition and volume buttons are in the usual places, with minimal relief



On the upper part, there's absolutely nothing: no infrared emitter, no speaker, no microphone or headphone connector.



On the lower part, there's one audio output, so I'm guessing the second one is located at the speaker. There's also the usb c port and the sim drawer. This phone can accommodate 2 sim cards in duplex mode. It is not possible to use a memory card.

This version of the phone has 12 Gb of ram and 512 of storage. I assume that other versions will be available, but at the time of writing I don't have the info



The 6.67-inch screen occupies around 90% of the phone's front surface. The edges are very thin and the screen is protected by a plastic film. The selfie sensor is quite discreet, barely visible at the top of the screen



The POCO F6 Pro had made good progress in terms of finish. La 7ème génération fait encore mieux et pas uniquement sur la gamme F. Le POCO X7 a également fait de beaux progrès mais c’est clairement le POCO F7 Pro qui fait le plus grand bond en avant comme vous pouvez le voir si je compare les 3 téléphones les uns à côté des autres

Specifications

The information below comes from the Device Info HW application. The application provides detailed technical information about the tested phone. I tested the 5G version with 12 Gb of RAM and 512 Gb of storage.

This phone runs on Qualcomm architecture, which means that all components like CPU, GPU, FPU, GPS, Bluetooth or 5G modem are linked to Qualcomm architecture

This configuration is not new, the POCO F6 already used the same CPU but the POCO F7 Pro is equipped with a better GPU

The memory is UFS 4, so it's ultra-high-performance and will let you switch from one application to another without having to wait.

CPU / GPU Performance

The POCO F7 Pro uses a Snapdragon 8 Gen 3 CPU, so it's clearly a high-end device offering excellent performance. The same goes for the GPU, which is an Adreno 750 GPU

No application or game will be able to withstand such power, it makes you wonder why manufacturers keep pushing phones to such performance levels

Benchmark Antutu/3DMark

I obtained a score of 1,409,028 points with Antutu v9; I was unable to run Antutu v8 on this phone. It doesn't matter, because this was also the case with the previous generation, so I can compare the F6 Pro to the F7 Pro under the same conditions

I'm measuring a 16% increase in performance. That may not sound like much, but we're talking about a level of performance that's already very high. This is the most powerful phone I've tested so far. Of course, there's always better on the market, but in this price bracket, it's undoubtedly the phone with the best performance/price ratio

The temperature rose by 6 degrees at the end of the test. That's a little above average, but with the load test to follow, I'll give you a more realistic idea of temperature management

Gross performance

To measure raw performance and power consumption, I successively push all components to maximum for several minutes. On this graph you can see the evolution of the test with the CPU first, followed by the GPU and then the FPU. I then push everything hard for several minutes to measure power consumption and temperature.

In terms of CPU consumption, I got an average consumption of around 9 watts, for the GPU I got 5.75 watts and 1.79 for the FPU.

I wasn't yet using this test protocol when I tested the POCO F6 Pro, so I can't compare it with this new model.

This level of consumption is the highest among the phones tested with this test, but at the same time, I hadn't yet tested phones of this type, so the result may be normal.

If I push all the components at the same time, I get an average consumption of 8.59 watts.

The battery temperature rose from 33 to 43 degrees and was still rising at the end of the test.

CPU temperature will take a gigantic leap from 30 to 93 degrees over the duration of the test. When all components are pushed to their maximum, the CPU temperature peaks at around 93°. I don't know how long the CPU can last with such a temperature, but over the 8-minute test, it didn't flinch. I didn't get any error messages. The phone was obviously hotter, but not to the point of not being able to hold it

With this test, I can also estimate the autonomy in an extreme scenario where the phone is pushed to the maximum all the time. Here I get 2h35. This may seem rather low, but this phone is very powerful and needs more power to operate. The battery would have had to be almost doubled to achieve a range equivalent to that of a normal phone

These are obviously not normal conditions, but it gives you an idea of what the phone's got up its sleeve




Gaming

To test the performance in game, I download the mobile PUBG game and evaluate the in-game experience, graphics level and depth of vision. This game is quite demanding and should help you evaluating the performance of a phone. I used PUBG Mobile to illustrate the in-game performance of this phone.

With the power of this phone, I can easily choose HD textures with a high frequency.

Power is DNA, and it's with games that it can fully express itself. The gaming experience is perfectly fluid, textures are highly detailed and appear quickly. The phone's temperature will inevitably rise, but I didn't feel any discomfort while gaming, as the cooling works well. If you push it to maximum all the time, it could become more problematic. I didn't encounter any problems during my test, even when I pushed it all the way

I'll let you see for yourself with this video

Mobile network sensitivity

To test the sensitivity to the mobile network, I use a probe which measures the quality of the mobile signal 24 hours a day (eg: cell id, rssi, rsrq, snr, frequency,...) for more than 3 years. I then measure the phone signal under the same conditions to compare them to the probe's reference signal.

Phones tested:





I took 6579 mobile signal measurements to obtain an average of -102.57 dBm with the phone and -105.55 dBm with the probe. This is a very good result for the POCO, and I wonder if it isn't one of the best POCOs I've tested.

I think antenna placement plays a role here because I noticed more notches than usual in the phone's chassis. So POCO has made up for lost time in terms of mobile network sensitivity. Samsung used to be better, now it's the other way round. I've had rather disappointing results with the latest Samsungs I've tested

Wifi performance

To test a phone's ability to receive the network properly, I take measurements near my router and then remotely (and always at the same place). This gives me an average in dBm where a value of -90 dBm indicates poorer performance than a value at -30 dBm.


Wifi signal



To assess sensitivity to the wifi signal, I took 154 measurements to obtain an average signal of -16.89 dBm. This is an excellent wifi signal level, and it's fairly stable throughout the measurements.

I measured a download speed of 866 mbps in 5 Ghz 300 in 2.4 Ghz.

This is an above-average level of speed achieved by combining several wifi antennas. I was surprised by the 300 mbps in 2.4 Ghz, I've never obtained such a level but I suspect it combines wifi with the mobile network

In any case the wifi is clearly a strength of this phone



Download/Upload speed

To test the speed in Wifi, I connect to my router in 2.4Ghz and 5Ghz (if available) and use the Ookla application to measure the speed.

GPS performance

To test the accuracy of the GPS signal, I use two positioning applications to evaluate the difference between the actual position and the position indicated by the phone. This test is done outdoors with nothing to obstruct the signal. An accuracy level of up to 3 meters can easily be corrected by an application (e.g. Google Maps).

To test the accuracy of the GPS signal, I use two measurements.

First, there's the accuracy calculated by the phone, which corresponds to the blue line on the graph.



Then there's the precision I've calculated between latitude/longitude and the phone's actual position. This is represented by the red line.

I took 3471 measurements to analyze signal accuracy. The signal accuracy needs about 30 seconds to stabilize and reach a stable accuracy level. The accuracy calculated by the phone is a little below 4 meters, with occasional bursts around 10 meters when the phone hasn't moved. The accuracy I calculated varies between 1 and 3 meters, with an average of 1.73 meters. This is an excellent level of accuracy, and one of the best I've tested so far.
The signal calculated by the phone is not stable, but I imagine that an application like Google Maps has a better calculation algorithm than the phone. So you shouldn't see such a big jump in accuracy.

My calculations show that the calculation of the real position is good and this is most probably linked to the combination of several frequencies. This phone is compatible with L1, L5, B1, B2, E1 and E5a frequencies. It uses GPS, Glonass, Beidu, Galiglé and QZSS.

The phone's GPS signal is therefore excellent, which is one of its strengths.

Battery range

To test battery life I developed an application that measures the battery level minute by minute until the battery is empty. This application consumes about ten percent of the phone's resources and I do a test with 100 brightness. This test aims to reproduce a contemplative use of a phone (e.g. surfing the internet, reading articles, spending time on social networks). These results are not valid for intensive gaming/streaming use.

I measured the charging speed with my UGREEN 100 watt charger and it took me 98 minutes to go from 1% to 100% battery. That's pretty slow compared to the phone's charging speed.

With the charger supplied in the box, charging time should be less than 30 minutes. That's the theory, because I tested the charger and it took me 125 minutes to charge the battery. I think there's a problem with the cable because, in principle, the charging time should be less.

This just goes to show how useful it is to have a charger and a cable adapted to the phone, because charging protocols are not always the same.

With this graph you can see that the charging speed is constant, which is very rare. I usually have a big slowdown around 80%. This is not at all the case here, so the charging speed of this battery is really excellent



I obtained an autonomy of 1347 minutes with brightness at 100% and 1877 minutes with brightness at 50%. These results are absolutely out of the ordinary. The only times I've achieved this kind of autonomy were with rugged phones equipped with huge batteries. The explanation for these results is quite simple:

The POCO F7 Pro has a higher capacity battery of 6000 mAh, giving it much greater autonomy than a phone with a 5000 mAh battery. However, this is only true if you use the phone at a low percentage of its capacity. If you only use the phone for surfing or doing other things that don't require energy, you'll get good battery life. If, on the other hand, you push the phone to the limit all the time, you won't last all day.

Photo camera test

To test the quality of photos produced by a phone, I do a technical test (resolution, sharpness, chromatic aberration,...) in studio (identical conditions) to evaluate the technical part objectively. From the second half of 2020, I built my own laboratory to take completely objective technical measurements. I then take pictures in real conditions to see how the camera performs. I then evaluate these photos according to my criteria but I publish the photos so that you can evaluate the result according to your criteria.

Hardware

The POCO X7 Pro has 4 photo sensors. The one for selfies is also present in other phones, an Omnivision OV20b40

The main sensor at the rear is a 50-megapixel Omnivision OVX8000. This is the same sensor used in the F6 Pro. This is a top-of-the-range Omnivision sensor, which I'll be able to compare with the recent Sony and Samsung models I've tested this year

The ultra-wide-angle sensor is also an Omnivision sensor, an 8 million-pixel OV08d10

Photo quality

Photo quality (indoor/studio)

The studio test is carried out under the same conditions so that the results can be compared on an equal basis. I calibrate my lighting for each test to obtain the same brightness and colour temperature. This test is a preliminary analysis of the technical qualities of a camera. Most phones fail this test, so you should also read the results of the other tests in the following paragraphs.

Omnivision OVX8000 main sensor



For this first studio test, I'm going to take a look at sharpness and color rendition. I can see here that POCO has chosen to emphasize the rubixcube, and the sharpness in this area is very good. You can even see the texture of the plastic where the lighting is stronger. In terms of color, I noticed a slightly yellow tint and a fairly significant blue enhancement. This is due to the intervention of HDR and AI, which can be deactivated if you're not too keen on this type of rendering.



With this second photo, I can focus a little more on sharpness, and what I noticed with the first photo is confirmed here too. The sharpness is excellent. The small letters of the Canadian banknote are very legible and the sharpness doesn't deteriorate much at the periphery. You'll see later in this test that the sharpness will also be very noticeable for outdoor shots. I don't see the white line around the letters indicating over-aggressive optimization, so this sharpness is not artificial.

Omnivision OV08d10 secondary sensor



The secondary sensor produces a correctly exposed image with less pronounced color saturation than the main sensor. Colors therefore appear more natural. I focused on the Statue of Liberty and the sharpness is decent, but below the level of sharpness of the main sensor. This is often the case with this type of sensor



In this photo, the lack of sharpness is more striking. The characters on the Canadian banknote are illegible, and the edges are completely blurred. The periphery is even worse. This kind of sensor isn't designed to go looking for details, so this sharpness problem will be less noticeable on landscape photos

Outdoor photo quality

Omnivision OVX8000 main sensor



I had sunny weather on the day I took these photos and the result is good overall.

The Omnivision sensor has a good rendering of details, the sharpness of the foliage is good even in depth. On the other hand, colors are a little too saturated. It certainly makes the photos more Instagrammable, but it's not very realistic. If you don't like it, you can always change the basic settings. These photos correspond to a result without changing the settings.

The dynamic range is good, I don't see any burnt areas in the sky, nor do I see any completely dark areas.



Omnivision OV08d10 secondary sensor



This type of sensor is ideal for landscape shots, provided you don't zoom in too far. The main weakness of ultra-wide-angle lenses is sharpness. This sensor is no exception to the rule. If you zoom in a little, you'll quickly notice a significant loss of detail

The hue of the photos is very similar to what I've seen with the main sensor. Colors are highly saturated and a little too cold. This reinforces the idea that this is a conscious choice by POCO in terms of color processing

Dynamic range is a little less good than the main sensor, but I think the result is good for this type of sensor.

Angle distortion is not very noticeable on photos of this type either.



Test photo / night

Omnivision OVX8000 main sensor



Night scenes are fairly well rendered in terms of exposure, I'd even say they're a little too bright. I'll come back to this point with the secondary sensor.

The night processing doesn't manage to totally erase the light halos and I find the smoothing a little too important. It's all very well if you're looking at the photos on a phone. If, on the other hand, you look at the photos on a large screen, you'll see a loss of detail on more complex elements like vegetation

I'm a little disappointed because this phone is very powerful, so it could use its power to bring more advanced processing for night photos



Omnivision OV08d10 secondary sensor



Sensors of this type are generally not very comfortable for night photos. However, I was positively surprised by the result. I thought the photos from the main sensor were too bright, whereas those from the secondary sensor are more realistic. The photo is darker overall and reflects reality better

Halo processing doesn't work very well either, but colors are more natural

Detail is even less good, but that's already the case for day photos, so it's the same for night photos

Video quality

Stabilisation

I've tested stabilization in 4k and 8k, so I'll start with stabilization in 4k.

Stabilization in 4k works pretty well, the shocks of walking are almost totally absorbed, you just see a little shake if you watch the video on a bigger screen.

In 8k, stabilization works fairly well too, although vibrations are more perceptible, but it's still very good. The 24 frames per second will also add instability if you watch this video on a 60 Hz screen.

You need power to stabilize this type of video, and it's clear that this phone has what it takes

Video 4k:



Video 8k:



Video normale conditions
4k video



This POCO F7 Pro is capable of filming in 4k and 60 fps, but also in 8k and 24 fps. I'll start with the 4k video:

The 60 frames per second smoothes out movements, so there's no jerkiness here. Colors are less saturated than with the camera, the color temperature is more accurate, and the image is also a little darker. Focusing is very fast and dynamic range is good. Sharpness is also good

Unfortunately, the zoom isn't much use, as you quickly fall into a muddle of pixels, but that's to be expected with a digital zoom

8k video is going to be much jerkier if you watch it on a 60 hz phone screen. This is purely mathematical. If the video sends 24 frames per second but the screen displays 60, there's a loss of information that causes jerkiness. The video retains more detail than in 4k, but it's still a phone. The quality is not comparable to a real 8k camera

This 8k format is not super useful on a phone because movements will be jerky and you won't see the difference between 4k and 8k on a 6.67-inch screen

8k video:

External audio quality

This test is intended to give you an overview of the volume and sound quality during calls and when listening to music through the external speakers.

I tested the audio quality on several levels and I'll start with the external speakers.

I created a 3-minute soundtrack with royalty-free tracks, taking care to vary the music styles.

The sound produced by this POCO is fairly balanced, I didn't notice any significant difference between the speakers. Sound quality is good across almost all frequencies, but the maximum volume is lower than average. This avoids sound distortion, but this isn't the phone you're going to burst your eardrums with

Well, I'll let you listen to it for yourself.



The sound quality on calls is good, the sound is softened and I don't hear as much treble as on some phones. The volume on the normal speaker is fairly moderate, even a little below average

If I switch the sound to the external speaker, the volume is obviously higher, but also remains below average. The sound quality, on the other hand, is quite good

Audio quality (headphones)

To test the quality of the phone's audio output, I connect the device's audio output to a measuring tool, then play sounds on all frequencies and measure the differences between the original sound and the sound produced by the phone. In this way I measure the phone's ability to correctly reproduce all sounds.


I measure audio quality with headphones, playing reference sounds that sweep all frequencies. I measure the difference between the reference sound and that of the phone with specialized software

My measurements show that the sound power of this phone is clearly below average. So this isn't the phone you're going to blow your ears out with. That's not a problem in itself, it's an observation.

I notice a deviation from the norm in the low and high frequencies. The curve gives the impression that the difference with a Samsung Galaxy S10+ is significant, but you have to look at the scale. The maximum deviation is just over 2 decibels.

I didn't notice any problems with subjective listening, I think only a very attentive ear would notice discrepancies in the fidelity of certain frequencies.

Screen quality

To test the screen, I use a colorimetric probe that measures the color accuracy of a screen, as well as other parameters to see if a screen is able to correctly reproduce an image. I also test the brightness level to determine if the screen will be able to display an image in full sunlight.

Colorimetry

The screen is AMOLED and has a resolution of 3200 by 1440 for a diagonal of 6.67 inches. This is an intermediate resolution between 2k and 4k on a fairly small surface. Pixel density is therefore very high, with 526 pixels per inch

The screen is compatible with HDR10, HLG, HDR10+ and Dolby Vision. It therefore covers just about every major standard on the market. It's also capable of operating at 60, 90 and 120 Hz in maximum resolution



The screen's basic configuration isn't too bad for colors. I obtained a delta E of 2.89 with good fidelity of red, green and blue, but the other colors deviate too much. White is too cold



For greys, the result is a little less good, I obtained a delta E of 6.38 with many greys in red

I suppose that a majority of users won't notice these differences unless they compare the phone with another well-calibrated phone

The good news is that this colorimetric discrepancy is easy to correct, especially if you have small fingers. You first need to keep the phone in "vivid" mode and then adjust the color temperature

You need to change the color temperature as below. With my big fingers, it took me a while to find the right position, but now that I have, I'm not going to touch anything else



With this little adjustment, I get a delta E of 1.45 for colors, with white going from 7.9 to 1.8. For grays, it's the same: from 6.38 to 1.45



With these settings, you get perfect colorimetry and a color space equivalent to DCI P3. This will enable you to watch films and series in HDR with the highest level of quality



I also noticed a few new features in the settings. You can change the resolution for a sharper image, but with the consequence that your phone will consume more power. It's the same for frequencies, a higher frequency can consume up to 30% more energy

I see they've also added an AI menu to enhance the image. I don't know what kind of improvement AI could bring. Colorimetry is already perfect.

On the other hand, I see a MEMC setting for the first time. This should enable you to avoid jerkiness in horizontal movements for all films displayed at less than 60 frames per second



Brightness / Contrast

The screen is able to exceed 500 cd/m² in a natural way, which is not bad, with the automatic mode I obtained a brightness of over 975 cd/m².

I've had better results on other phones, but it all depends on how the light sensor works. I never know at what angle to flood it with light, so the results can sometimes be different.

With 975 cd/m² you can use this screen under the sun without any loss of brightness. Don't forget that if you use this phone in bright light, it will also consume more energy and this will affect your battery life.

Contrast

I also measured the contrast and got over 18000 to 1. Usually I get infinite contrast but I think it's related to the minimum brightness. I used my most sensitive probe and it detects the deepest blacks more easily.

At 18000 to 1, you've got a screen with absolutely impeccable contrast

Accessories POCO F7 Pro

Compare POCO F7 Pro with the others

Test / Review conclusion

The POCO F7 Pro is a real monster of power, and frankly, I can't see what could put it off. I measured a 16% increase over the previous model, and at that level, it's clearly a phone that has no trouble taking on all the tasks of everyday life

Raw power isn't everything. What also surprised me was its heat management. I pushed it hard for eight minutes, and it went up to 93 degrees, without slowing down, without crashing, nothing. Yes, it heats up, that's normal, but not to the point of being scorching hot or unpleasant in the hand

Another strong point: connectivity. Network reception, Wi-Fi and GPS are well above average. POCO sometimes lagged behind in this area, but this time they've put things right

The screen is as good as ever. Basic colorimetry is good, and with a few adjustments, you can achieve something almost perfect. Contrast is good, resolution is ultra-dense, and above all, it goes up to 120 Hz with compatibility with most HDR-type formats

As for the battery, it charges ultra-fast. In normal use, autonomy is decent, but as soon as you push the phone a little too hard, you quickly realize that it's greedy. If you're a heavy user, don't expect exceptional endurance

The sound is also a pleasant surprise. Quality is excellent, whether for calls or music. Sound power isn't incredible, but the advantage is that distortion is almost non-existent. The sound is clear and well-balanced

On the photo side, POCO has used the same sensor as on the previous generation. Photos are good, videos up to 8K, but software processing is too aggressive for my taste. Sharpness is there, but colors are sometimes too accentuated. For the same price, a Samsung will produce better photos but will not have the same power

In terms of design, POCO has made further progress in terms of finish. The assembly is clean, and visually, I think it's a pretty good phone

So yes, this phone doesn't have any major flaws, but there are a few things to be aware of

First of all, as always with Xiaomi, there are lots of pre-installed apps. This weighs down the home screen a little, and frankly, it's a bit much

Secondly, the night mode is okay, but not exceptional. For a phone in this range, you'd expect better. Even in daylight, the photo processing is a little too forced. For a more natural rendering, it's best to disable AI and HDR

Autonomy could be disappointing. The battery is 20% bigger than average, but since the phone consumes a lot of power, you're not going to gain 20% in autonomy. This isn't a bug, it's just a logical consequence of such a powerful processor

And finally, one last point that remains an unknown: durability. For the moment, it can handle high temperatures well, but will this have an impact in the long term? It's hard to say

That's all for the POCO F7 Pro, I hope this test has met your expectations. If you have any questions, don't hesitate to ask in the comments
