Up to now, Cubot was exclusively represented with devices below the 150$ limit on the market, but could blossom out to one of the strongest Chinese manufacturers in this price range thanks to a reliable quality and good price/performance ratio. With Cubot Power, the Chinese mobile phone manufacturer now finally presents a more powerful smartphone.

The new Cubot Power houses an Helio P23 and is thus located in the mid-range in terms of performance. The phone also has a 6-inch display in 18:9 format, 6GB RAM and 128GB ROM. The gigantic 6000mAh battery, with which Cubot Power actually already belongs to the so-called Big-Battery phones, is also outstanding in the datasheet. The camera on the rear has a resolution of 20 megapixels. The following test report will tell you what the Cubot Power can do in practical use.

The design of Cubot Power is similar to the cheaper Cubot X18 Plus. Unfortunately, I have to mention the first weak spot of the smartphone here: The rear and the frame are made of plastic, just like the cheaper models. Theoretically, there is nothing wrong with plastic smartphones because, unlike glass or metal, they can save some weight and reception is usually better. The problem, however, is that Cubot has a plastic rear with a shiny surface. This enhances the appearance of the smartphone, but also makes it very susceptible to scratches. Now, you have two options: Either you use the smartphone only with the included protective cover, or you accept that there are inevitably small scratches on the rear. Very unsightly!

The 18:9 format makes the smartphone slightly longer than the old 16:9 mobile phones. The dimensions are 158 x 74 x 11mm. The thickness of 1.1cm is still pleasant in view of the large battery. The weight of 211g is on average for a smartphone with this battery size. In practice, Cubot Power does neither feel particularly well in the hand nor does the smartphone feel very high-quality. However, it still sits comfortably in the hand and is not noticeable in the trouser pocket. Also, a one-handed operation is still possible due to the 18:9 format despite the very large display.

The front is almost completely covered by the display, so that the bezels left and right (2mm) and above and below (1cm) are relatively small. The smartphone is operated with on-screen buttons, whose position, unfortunately, cannot be adjusted in the settings. Above the display, there is a notification LED next to earpiece, front camera and proximity sensor.

Cubot distinguishes itself as one of the few manufacturers that does not allow itself to be carried away by an exaggerated screen-to-body ratio. A fake dual camera with no added value has been dispensed with. Instead, only the fingerprint scanner and an LED flash are located below the camera. The fingerprint scanner does a very good job and unlocks the smartphone from standby in less than a second. Error detection is virtually non-existent.

On the bottom side, there is a modern USB Type-C connector. It also functions with an adapter as an OTG connector, but USB Type-C headphones are not recognized. However, this should not disturb most users, as Cubot Power still has a conventional 3.5mm headphone connection.

Two Nano SIM cards can be inserted laterally into a slot. Alternatively, one of the two SIM slots can be used for storage expansion. However, this will not be necessary for most users, as the internal storage has an impressive size of 128GB.

Overall, Cubot Power is a well-built smartphone. Of course, as a buyer, you should be aware that you don’t buy a handy smartphone here, because the mobile phone also weighs a lot due to its 6000mAh battery. However, this cannot be negatively charged to the smartphone. However, the phone has to take criticism for the shiny plastic rear. If you want to have an undamaged smartphone for a long time, you need the protective cover for Cubot Power.

Cubot Power offers a very large 6-inch display, which is ideal for gaming and watching videos. Thanks to the 18:9 format and the small bezels, the device is still relatively handy. The display has a Full HD+ resolution of 2160 x 1080 pixels. Thus, the image is completely sharp and individual pixels are no longer visible thanks to 402ppi. It is a classic IPS panel that satisfies in the test with good viewing angle stability, strong contrasts and vivid colours. Although the plastic casing isn’t really worthy of a 200$-phone, the display doesn’t have to hide from the competition. The brightness is sufficiently high and ensures good operation even in sunlight. The automatic brightness control also works well.

Cubot Power 10The touchscreen registers up to 10 touch points simultaneously and works reliably and quickly. Concerning the display glass, Cubot does not use the product of a well-known manufacturer, but in contrast to the rear, the front of the mobile phone is very scratch-resistant. A load test with a screwdriver and a bunch of keys left no traces on the phone.


Cubot Power houses an Helio P23 processor. In view of the slower CPUs Cubot used in its predecessor models, the P23 takes power to a new level for the manufacturer. The Octa Core is quite similar to the Helio P25, only the Cortex A53 cores clock differently: from 4 x 2.6 GHz to 4 x 2.3 GHz and the energy saving cluster from 4 x 1.6 GHz to 4 x 1.65 GHz. The Mali G71 with 700 MHz is now used as GPU instead of the Mali T880 with 900 MHz. On the data sheet, this means less power, even if only minimal, but the Helio P23 is more energy-efficient. In practice, the Helio P23 runs very smoothly on Cubot Power. Subjectively, I would even say that Cubot Power with its Helio P23 runs faster than all the P23 and P25 devices I have tested so far. There are virtually no loading times in the system and opening apps is also pleasantly fast. When browsing the Internet or the Facebook timeline, there are occasionally minimal delays that do not occur with more expensive devices. Apart from that, the performance is very smooth. Games can also still be played well on the device, which is also one of the predestined areas of application of Cubot Power with its strong battery. Simple games like Temple Run are of course no problem for the mobile phone anyway, but even demanding titles like PUBG or Asphalt 8 run smoothly.

Another advantage of Cubot Power are its large storage modules. The main storage contains 6GB of RAM and is therefore also suitable for excessive multitasking. With a speed of 6GB/s, the storage is sufficiently fast. Awesome 128GB are also available for saving apps, games and music. The reading/writing speed is very high at 180/195 megabytes per second. Most users won’t need that much storage, but it’s still a nice addition to be able to store the entire music collection on the phone without having to rely on a Micro-SD.

Cubot Power is a very high-performance smartphone. Although it can’t quite keep up with mid-range leader Xiaomi Redmi Note 5, the performance is completely sufficient for most users. Compared to other devices in the price range, Cubot Power is still above-average fast and even current games run smoothly.

Cubot Power runs with the latest Android 8.1. The surface has not been changed at all by the manufacturer and you get a clean and tidy system. Only the options menu has been extended in some places and DuraSpeed has been integrated for system optimization. The Android 8 features like the picture-in-picture function or the revised notification management are all available. The Google Play Store is, of course, pre-installed by default.


The camera on the rear has a no further specified Samsung sensor with 20 megapixels and an f/2.0 aperture. The front camera has 13 megapixels. The manufacturer advertises the camera with an improved zoom technology with few losses. Unfortunately, as is often the case, this function does not really make a difference to normal digital zoom. Another additional function is the night mode, in which the Cubot Power optimizes settings for low-light photography and exploits the advantages of its 6P lens. In fact, this doesn’t work so badly in practice and the night shots look much better when taken in this mode. Apart from that, the camera of Cubot Power is convincing in terms of standard photos. The images have good colour representation and sharpness. The white balance is also usually very good, at least with the rear camera. So the camera still copes well with the interplay of shadow and light. The 13-megapixel front camera can also take beautiful photos, but in strong sunlight, there are often problems with white balance and the images appear overexposed. Here too, however, one can still speak of good quality overall.

Videos can be recorded in Full-HD resolution and have a good quality with sufficient light. The sound is also neat. In addition, the videos are to be supported by electronic image stabilization if required. However, this function has no effect at all and accordingly videos in motion are rather shaky.


Cubot Power 9As always, Cubot Power is equipped with a Dual-SIM function. Two Nano-SIM cards can be operated simultaneously in the mobile phone. Alternatively, one of the two SIM slots can be used for storage expansion. However, due to the 128GB internal storage this should hardly be necessary. Cubot Power supports all main frequencies required. There are therefore no limits to mobile data use. Bluetooth 4.2 and Dual-Band WiFi are available. In addition to the standard sensors, there is also a gyroscope and an E-compass; GPS is also supported. The reception values of WiFi, GPS and network are all very strong – here the plastic rear has a positive effect.

Cubot Power System Benchmarks 21The call quality is on average and during telephone calls, the voices are transmitted well on both sides. The hands-free function can also be used well. The mono-speaker on the bottom of the phone produces a decent sound. But you don’t get a really good sound quality, because the sound is clearly lacking bass. Alternatively, headphones can be connected via the 3.5mm connector for listening to music.


In this respect, Cubot Power has a lot to offer. With 6000mAh, the Power offers almost twice the capacity of a normal 6-inch mobile phone. The Helio P23 also works quite energy-efficiently. In practice, I could use the mobile phone for three days with an average usage of 2-3 hours per day without recharging. The consumption values are consistently well. About 12% is needed for one hour of high-end gaming, about 8% is lost when watching a one-hour Full-HD video on YouTube (both activities were performed with half display brightness).

Battery lifetime Result Unit: hours

Possessing Cubot Power, you rarely have to worry about an empty battery. At the same time, it must be said that the smartphone with its 6000mAh achieves about the same battery life as Redmi Note 5 with 4000mAh and correspondingly lighter weight. In this respect, a good runtime is not necessarily the best efficiency.

Cubot Power is charged with a 5V/2A power supply. The entire charging process takes 3.5 hours.

Conclusion and alternative

Joscha Becking:

Cubot Power is an almost entirely consistent good smartphone. The biggest weak spot of the phone is the rear made of shiny plastic. It is simply no-go that, despite careful use, scratches appear on the rear cover after just a few days. If you don’t attach much importance to the appearance of your smartphone, or use the protective cover provided anyway, you won’t mind. Otherwise, you get a very fast working device with the latest Android 8.1, a good camera and a very good battery life. Also the reception values are all very good. Smaller criticisms such as the mediocre loudspeaker and the lack of EIS stabilization hardly cloud the otherwise positive overall impression.

As an alternative to Cubot Power, Xiaomi Redmi Note 5 can be mentioned. If you want even more battery power, you can also take a look at the new Big-Battery champion Ulefone Power 5.

Finally, a word about the price: Cubot Power is currently on sale for an impressive 250$. At the current price, we cannot speak of a good price/performance ratio. In our estimation, the price will fall to about 180$ very soon.
