With Oukitel K10000 Pro, the manufacturer launches a new edition of the epitome of battery monsters. The phone provides 10,000mAh, which is the threefold capacity that ordinary smartphones have. Compared to the predecessor, the hardware has been improved. The phone now houses an octa-core processor, a full-HD display and a better camera. Whether or not the smartphone did a good job in the test, you’ll find out in the following review.
Design and build quality
Probably, Oukitel K10000 Pro is not the most beautiful smartphone of the year, as the design requires some time getting used to it. On the other hand, Oukitel K10000 Pro is simply not a normal smartphone with its oversize battery, so the unusual design underlines its singularity. In any case, beauty is in the eye of the beholder. Build quality is quite good. The look slightly resembles current outdoor smartphones. We doubt however that the device is well protected against falling down. The manufacturer does also not advertise the phone with outdoor qualities. In contrast to the predecessor, the casing now consists almost entirely of plastic in order to reduce weight. It remains however a mystery if these 20g less weight have really been necessary.
Compared to the predecessor, Oukitel K10000 Pro looks a bit cheaper. There is only one metal strip integrated in the frame and it is cased in plastic with a metallic look. The strip encloses power button and volume control, which are not firmly attached to the casing. On the left side, you can find the SIM tray, in which you can insert either 2 Nano-SIM cards or 1 Nano-SIM and 1 micro-SD card. The battery is not replaceable. According to the manufacturer, the rear side is covered with Australian calfskin. We do not dare to confirm the authenticity of the material. However, K10000 Pro survived a test with a lighter without problems, as there were neither burnt spots nor plastic smell. This is a strong sign for real leather.
Holding the smartphone in the hand, you instantly notice the massive weight of 295g (about twice the weight of normal phones). The dimensions are 160x74x14mm. Besides the heavy weight, you also notice the thickness of 1.4cm when having the phone in your trouser pocket. The huge battery capacity comes at a price; you have to cope with a bulky phone. On the other hand, Oukitel tried to give the device a look which matches the concept of the phone.
Oukitel K10000 Pro scope of delivery
The scope of delivery contains a quick-charge adapter, a screen protector, a micro-USB cable, a SIM ejection tool, two protective covers and operating instructions. One of the protective covers is made of flexible plastic. The other one is a bit bigger, consists of black imitation leather and covers the phone’s front as well. Oukitel K10000 Pro’s micro-USB plug is slightly longer than normal micro-USB plugs. The phone can be used only with this cable, therefore, you should keep an eye on it!
Oukitel K10000 Pro houses a full-HD display with a 1920*1080pixels resolution. In comparison to the previous model, resolution has been improved, which results in a sharper image on the 5.5-inch display. With a pixel density of 400PPI you can enjoy a clear image without any single pixels. It is a normal IPS panel, which offers good contrast and high brightness. It is possible to use the phone outside. Color representation on the other hand is not really convincing. The display has a slight blue cast. Unfortunately, the Mediatek MiraVision tool, with which you are able to customize the display, is not available, so you do not have any possibility to alter the display. In daily use you barely notice the blue cast and it is not disturbing, but if you put the phone next to a device with better display, the blue cast clearly stands out.
The display glass is not rounded off at the sides and it is a true magnet to fingerprints. Further, it is not really scratch-resistant. Swiping over the display with a screwdriver (with medium pressure), already leaves some damage. You should use the provided screen protector, if you like to keep the display free from scratches. The touchscreen works fast and precisely and registers up to 5 points of contact simultaneously. Below the display, there are 3 soft touch buttons. However, there is no notification LED. The display has additional features like gesture control and SmartWake. Whereas gesture control is not that useful, the SmartWake function is a nice feature.
Oukitel K10000 Pro uses a Mediatek MT6750 processor. The octa-core CPU has 2 quad-core clusters with 4 cores and has been launched in the second quarter in 2016. The first cluster works with ARM-A53 cores with 1.5GHz each. The second cluster houses 4 slower clocking ARM-A53 cores with 1.0GHz each. These features offer more performance than the MT6737 processor of K10000. However, Oukitel K10000 Pro is still no performance monster. In daily use, you get a nice speed for almost all fields of application. Apps open fast and navigating the system happens quickly and smoothly. Surfing the internet and watching YouTube is also not a problem. The phone cannot keep up with Redmi Note 4X (similar price) in terms of gaming performance. Hardcore gamers will probably choose a faster device. Nevertheless, you can play some games. With low graphics settings, the Mali T860 GPU makes it possible to play even Asphalt 8 almost smoothly. Other 3D games like Dead Trigger 2 or Overkill 3 can also be played. However, the device is not suitable for real gamers.
The Antutu benchmark of 44,000 is a bit less than you would expect from a current china phone in this price range. The speed of the RAM is only on average with 4GB/s, as is the reading/writing speed with 100/80MB/s. Ex works, you have a 32GB storage available. if necessary, the storage can be expanded via a micro-SD card. The 3GB of RAM provide basic multitasking ability. You can easily have several apps opened in the background without the speed slowing down.
Oukitel K10000 Pro runs with Android 7 Nougat. The Google Playstore is preinstalled, but you cannot find any bloatware. The manufacturer adjusted the launcher. Settings, lock screen and quick links remain unchanged, but apps have different icons. You can choose from 3 designs. The standard design is not visually appealing, as almost all app icons have a different layout, which makes the home screen look kind of untidy. The standard Android theme or the overflowing theme look better.
During the test, the Android 7 system was always fast and stable. There were no crashes. System updates are installed via OTA.
Oukitel K10000 Pro houses a 13MP rear camera with an aperture of f/2.2 and a 5MP front camera. The camera of K10000 was one of the phone’s weak spots. Fortunately, Oukitel improved the camera significantly. Sharpness is very good and color representation is mostly accurate. Considering the price range, Oukitel K10000 Pro is above average. As it is the case with all cheap smartphones, image quality deteriorates strongly as soon as less light is available. In good lighting conditions, however, you can take nice photos. The 5MP camera likewise takes nice pictures in good lighting conditions. If there is less light, image quality also deteriorates quickly.
Oukitel scores big with the K10000 Pro’s camera! Pictures taken in good lighting conditions are very sharp and have a good color representation.
Oukitel K10000 Pro is a dual-SIM smartphone. You can use 2 Nano-SIMs simultaneously. If you expand the storage with a micro-SD card, you have to go without the dual-SIM function. The phone supports the following frequencies:
GSM 850 MHz, GSM 900 MHz, GSM 1800 MHz, GSM 1900 MHz, W-CDMA 900 MHz, W-CDMA 2100 MHz, LTE 800 MHz, LTE 900 MHz, LTE 1800 MHz, LTE 2100 MHz, LTE 2600 MHz
Reception was on average and there were no problems when using mobile data. Voice quality is good on both ends and you can be heard well. The speakerphone does also a nice job.
The integrated speaker is on average, at the most. The sound is sufficiently loud, but it sounds tinny and there are some distortions at full volume. The sound is okay for watching a video clip occasionally, but the phone is not a mobile jukebox. Connecting headphones to Oukitel K10000 Pro, you get a good sound.
The Wi-Fi module uses a/b/g/n-standard and supports 2.4GHz and 5GHz networks. Signal strength is on average and you still have good reception even if you’re several meters away from the router. Bluetooth is supported with the new 4.2 standard, which you cannot take for granted in the price range. In return, the manufacturer saved on the sensors. The phone provides direction, proximity and brightness sensors, but a gyroscope or an e-compass are not available. Therefore, you cannot use VR glasses and pedestrian navigation is more difficult as well.
The GPS module on the other hand determines the position well and precisely. Because of the missing compass you only see in which direction you’re looking if you’re moving. Apart from that, Oukitel K10000 Pro can be used as navigation system without further problems.
Oukitel K10000 Pro houses a 10,000mAh battery, which is three to four times the capacity of an ordinary smartphone. The phone was designed for those who would like to use their phone several days without charging. Choosing Oukitel K10000 Pro, you definitely made the right choice. With an active use of 3-4 hours a day, you get at least 4 days of run time. Those using their phone just one hour a day can even get through the whole week without charging. This much stamina is impressive. Playing a 1-hour-YouTube video with full-HD resolution and medium brightness consumes 6% of the battery. In the PCMark test, the phone lasted for 18.5hours. The battery is simply awesome! However, we have to say that Oukitel K10000 Pro does not work very efficiently. Redmi 4 or Xiaomi Max 2 get similar good values, although they have only about half the capacity. We hope that Oukitel will be able to improve the battery life with further system updates. We guess that this is possible. We can also confirm the battery capacity; in the test, 9700mA were transmitted into the battery.
Oukitel K10000 Pro offers the possibility to charge other phones via OTG. Almost every current Android smartphone has this function, but K10000 is especially suitable because of its big battery, which is almost a power bank. The phone is charged with the 12V/2A quick-charge function Pump Express 2.0 by Mediatek. The phone is fully charged in 2.5 hours. However, the smartphone gets dangerously hot (up to 48°C) when it is charged with the quick-charge adapter. We doubt that this is healthy for the battery’s life. We advise to charge the phone with a normal charger overnight, if you’re not in a hurry.
