Last time I got a CUBOT H3 with 6000 mAh battery from CUBOT, I really like this kind of mobile phone that does not need to be recharged frequently. Yeah, Nothing beats a lot of battery power – the new Oukitel K3 offers exactly that: a 6000mAH battery at an unbeatable price. With its specifications, it fits exactly into the current lower mid-range: 4GB RAM, 64GB memory, 5.5″ Full HD display and the popular MediaTek MT6750T. With the hardware you get usable performance for everyday use at a price of nearly 120€. But we’ve seen the specifications before. The Oukitel K6000 Plus was released six months ago and was convincing in its test report. With its aluminium back it costs 20€ more than the Oukitel K3.
The newer and cheaper K3, with double dual cam and clean launcher or the well-tried K6000 Plus. Does the individual sensor of the Oukitel K6000 Plus provide better images? In the test report for the K3 we find out!
The Oukitel K3 is externally very opposed. Of its dimensions, which also come from the large battery, it is a real boulder: 155.7 x 77.7 x 9.9 mm at 240g. But on the other hand, it is then so elegantly in black and gold. With small decorative elements, such as the camera mount in gold, the screws and notches, it looks filigree and the symmetry is pleasing. The Oukitel K3 is also available in blue.
I think the design was a great choice. This does not apply to the haptics and materials. On the one hand, it is neatly processed; no creaking or gap dimensions. Unfortunately the back is made of plastic. The Oukitel K3 has a beautifully curved edge and therefore lies securely in the hand. But you can’t get rid of the plastic feeling. The corners are also annoying: they have become too sharp-edged and pointed. So the lower right corner presses after some time in the hand. Above and below the Oukitel K3 is just as radical. No curves and the metal frame is discontinued. Instead, one finds plastic with a pattern that is supposed to resemble carbon. That’s not fancy, the connections look even worse and the haptics don’t improve.
The camera is also striking. The golden bezel protrudes one millimetre, but is neatly integrated into the case. The power button and volume rocker can be found on the right-hand side. They wobble back and forth in their version, as well as the SIM card slot. At the top you will find the Kinken connection – bottom micro USB, two cut-outs for speakers and a hole for the microphone. Why the hole, if it’s just a mono speaker anyway. The micro USB is also a problem: it’s too far inside the case! This means: either use the supplied cable or get an adapter.
Below the display are the three typical keys: Back and App overview as non-illuminated sensor keys and the depressable home button at the same time as a fingerprint sensor. I was already aware at the beginning that you have to stick back when looking at the Oukitel K3, so my expectation of the smartphone was the same. I like the design: clean, reasonably elegant and it looks good. However, I don’t like the haptic – the thickness and weight are fine – the angular corners should remain a unique experiment and a higher quality back is desirable.
Scope of delivery of the Oukitel K3
In addition to the smartphone, the scope of delivery includes the typical quick start guide, charger (9V2A MediTek PumpExpress), micro-USB cable with long plug and a thin plastic back cover. This is matt black and very handy, but the smartphone is easy to remove; we didn’t use it in the test phase. A second display foil and an OTG adapter are also included. The latter allows the Oukitel K3 to be used as a power bank and to load other devices on the road.
No experiments on the display; this is a normal IPS panel with a screen diagonal of 5.5 inches. With the Full HD resolution you get a PPI of 401, so that no single pixels are visible anymore. The panel is not AMOLED level, but provides rich colors and a natural display. It is also very stable in terms of viewing angle and can be bright enough. To counteract scratches and supports, it is made of Asahi glass and a glass foil is available ex works.
At the edges it is rounded 2.5D, but we had to take a close look at it. The display does not occupy the complete front, because around the display is a 3mm wide plastic frame. The Oukitel K3 has a very nice curve, but only one part of it is made of matt gold metal and 2.5D glass, the rest of it is made of plastic.
The K3 registers 5 touch points at the same time and also implements them very precisely. Even fast writers can cope with the battery monster. Mira Vision is on board to adapt to your personal preferences. Here, the display can be given the subjectively best possible polish – or it can even be made worse. In the factory state we like the display of the K3 very much and there is nothing to criticize.
The Oukitel K3 is equipped with the currently popular MediaTek Octa-Core MT6750T. The lower mid-range SoC has been on the market for a long time, but it does its job satisfactorily. Inside, four ARM-A53 cores operate at 1.5 GHz and four at 1.0 GHz. With the CPU, mach in AnTuTu Score reaches a good 43,000 points – but the energy management could be better, compared to processors like the Helio P20 from Mediatek.
The MT6750T is supported by the Mali-T860 GPU and 4 GB of RAM. In everyday life you don’t get any problems with the hardware. The system runs smoothly and I ran every application without complaining. Every now and then, when the K3 is asked to do a lot, a second of remembrance passes or you have to take more time when starting up the system. The distance to the flagships is noticeable. Nevertheless, Android is fun with the Octa-Core.
With graphics bombs, you have to put back a little bit; e. g. Asphalt 8 runs at the highest settings, but not jerk-free. If you control the settings back to “Medium”, the game doesn’t bring our Oukitel K3 to its knees at any time.
The memory is also pleasingly large at 64GB. Of this, 53GB are still available. But the memory is not one of the fastest. This reaches values of 98 MB/s read and 130 MB/s write speed. The main memory is 3.6 GB/second, but fast enough. We noticed that the main memory is usually well filled, which speaks for a well optimized system.
The Oukitel K3 comes with pure Android 7.0! You will only find fitting with a trained eye: the Quick-Settings have a grey background, with our black K3 this is black – top! The whole OS looks super clean and brings the classic Android experience. You won’t find many extras in the settings: Smart Wake is on board as well as the 3-finger screenshot. In addition, there is a super saver mode on the Oukitel smartphone. If you turn it on, you are limited to the basic functions such as SMS and telephone and can use the 6000 mAh battery even longer.
The Oukitel receives twice as many camera sensors. And it is wrongly expressed. Not only on the back you will find a dual-cam with flash, but also on the front. The dual madness is unfortunately moronic: at our flagships, the two sensors produce images with a depth effect, like a SLR camera. In the cheap smartphones, however, the effect is only generated digitally and shows up in a sharp area inside the phone and the rest remains blurry or blurred.
In the Oukitel K3 this is now also reproduced on the front side to achieve very nice selfies. Overkill or sensible?
On the one hand, we are very positively surprised by the camera of the Oukitel K3. The offered quality is normally available in the upper middle class, not with a 120€ smartphone. The sensor of the K3 releases with 13MP and has an aperture of f2.2 and is interpolated to 16MP on the back. Additionally, a sensor with 0.3MP is installed, which is interpolated to 2MP. The same hardware is found on the front, but with a smaller flash.
The rear camera is convincing throughout. The pictures taken are realistically reproduced. We notice that the colours are not too pale or exaggerated. You can zoom in on the image without getting a pixel mash on the screen. But the Oukitel K3 still can’t match the brilliance of the expensive smartphone sensors.
The autofocus does not always work accurately enough, so you need to refocus quickly. Backlighting can cause images to be overexposed quickly. And different modes are sometimes lacking in the app – but that’s already been criticized, the Oukitel K3 is convincing when it comes to camera.
In the app you will find settings, 4 modes: Video, Photo, Face Enhancements, Panorama and SLR. Under photo you can switch on the HDR option, which convinces and delivers the typical HDR effect.
For the front camera, there are the same modes except Panorama. Especially the facial embellishments are discreetly Asian (“big eyes”). Unfortunately, the camera for Selfies can’t tie in with the performance of the rear camera! Selfies to send them you get, but you shouldn’t use them for the next slideshow. The front camera’s shots lack sharpness and contrast, and they quickly get overexposed. Selfies can also use the two sensors and provoke a depth-of-field effect – which is the proverb. The SLR effect is digitally superimposed on the image in the middle or the manually focused spot – the result speaks for itself, that’s all it takes for a toy.
The Oukitel K3 is a dual SIM mobile phone. In the sled there is room for a nano SIM and a micro SIM. If you don’t use the latter, you can also use a microSD card for memory expansion. For use in this country all necessary 2G, 3G and 4G nets are on board, including the important LTE volume 20, and after the test we can certify the Oukitel K3 to have an excellent reception. Due to the plastic back and additional receiving strips in the frame, I had a net at any time.
The K3 also shows no nakedness when it comes to determining the position: GPS, A-GPS and GLONASS are used for this purpose and the position could be determined accurately to within 3m. With the built-in compass, the pedestrian navigation worked perfectly! WLAN access is via the b/g/n standard, in both 2.4 and 5 GHz. The current Bluetooth 4.2 is also built in.
The fingerprint sensor does a good and reliable job. When the screen is switched off, you simply place your finger on the screen and the device is unlocked: this takes less than a second, but it works almost always. We are a bit annoyed about the micro USB port. It’s still the most built-in port on smartphones, but when does it start to rely on the new USB Type-C. This makes the battery-powered smartphone feel good again with additional sensors: in addition to the three standards, a gyroscope is also available.
Let us now turn to the most important discipline. If you buy a smartphone with a large 6000mAh you also expect a corresponding battery life – you also accept a higher weight and larger dimensions.
The Oukitel K3 offers a score of 12:18 hours in the Battery Mark or, to put it another way: with one charge I managed to make ends meet for two days in the hot test phase with 4 hours of display-on-time, benchmarks, test pictures and so on! All smartphone users will get a companion with the K3 with continuous-running qualities.
But it is also noticeable that Qualcomm’s Snapdragon CPUs have better control over energy management. The MediaTek processors are a little behind. MediaTek’s Pump Express fast-charge function is available for this purpose. And so the battery is filled up really fast with 9V/2A: from 0 to 100% in 2:00. This is an announcement for a capacity of 6000 mAh. Half the battery is charged in 45 minutes, 90% in 90 minutes.
