Oukitel K6000 Plus Smartphone Review

Cram-packed. The Chinese smartphone presents decent figures on paper, such as 4 gigabytes of RAM, 64 gigabytes of storage, a 16-megapixel camera, and a strong battery. Is the additionally attractive smartphone also a power bundle in practice?

For the original German review, see here.

The battery has a capacity of 6080 mAh - which is quite impressive. However, the runtime and performance also depend on screen size and other factors. After all, a 5.5-inch Full HD needs to be powered here. We thus compare the K6000 Plus by Oukitel with some other giants, such as Honor's 6X and Acer's Liquid Z6 Plus, as well as some considerably cheaper phones like Sony's Xperia E5 that can compete with the K6000 Plus.

Case

Compared with the aforementioned rivals, Honor's 6X and Acer's Liquid Z6 Plus, the K6000 Plus is longer and thicker with 155 x 76.6 x 9.6 millimeters (~6.1 x 3 x 0.38 in). Its strong battery also makes it heavier than its opponents that remain below 170 grams (~6 oz) compared to over 200 grams (~7 oz).

The chassis makes a good impression at first glance, and the color transitions between the different materials are also well-implemented in our red and gold colored review sample. However, some weaknesses are found when looking closer: The polished edges of the rear aluminum cover do not close flush in the dedicated and also beveled plastic flaps in the antenna area. Thus, the bezel does not make an overall smooth impression when looking from the side.

The camera recess on the rear protrudes only slightly out of the casing. However, this is still enough to cause it to wobble when using the smartphone on a table. Two illuminated sensor buttons under the screen give the smartphone a high-quality impression.

The smartphone is pleasant to hold considering its size. The power button and volume control do not have much play and are both situated on the right where the right thumb can use them comfortably. Furthermore, Oukitel's software facilitates using the large phone - more about that in the Input Devices and Handling section.

Connectivity

Two speaker openings on the USB port's right and left suggest stereo speakers. However, this is deceiving. The K6000 Plus has only a mono speaker. The USB port in the K6000 Plus is still micro-B, and thus Oukitel has not yet updated to the new Type-C format. At least it is a USB OTG port, i.e. a USB flash drive can be connected via a corresponding adapter. Wi-Fi Direct is present for transmitting the (complete) screen content to a projector or TV. Furthermore, the K6000 Plus has an LED above the screen. The user can disable it separately for low battery, charging, and missed call/message.

Four cores of the octa-core MT6750T, a variant of the Mediatek MT6750 with a Mali-T860 GPU introduced in spring 2016, clock at up to 1.0 gigahertz and the other four at 1.5 gigahertz. Oukitel combines this with the SoC's maximum of four gigabytes. The 64-GB eMMC storage is also generous and the user has almost 54 GB available at the beginning.

Software

The user interface is virtually untouched: Android 7 is installed on the review sample. However, Oukitel has completely replaced the Android-typical icons with its own - even those of Google Maps or Play Store. Only few additional apps have been preloaded. Among them a QR scanner and an FM radio that the K6000 owes to the Mediatek SoC. The system menu soon makes it obvious that everything that does not come from Google largely correlates with English-language notifications - or provides a funny translation into German, for example when changing the lock screen background.

Communication and GPS

The K6000 Plus only supports the 2.4-GHz band in terms of Wi-Fi. Thus, it lacks the ac-standard with higher data rates that many routers now offer. The transmission speeds between our Linksys EA 8500 router and the handset is not very satisfactory by today's standards. Oukitel has also omitted some frequencies for mobile data usage. This involves the US American 3G frequencies of around 850 and 900 MHz, and the 2, 4, 13, 17, and 25 LTE bands. It will be possible to make calls anyway. Band 20 (800 MHz) that is important for Europe is present.

Thanks to two SIM card slots, the user can save money if a cheap pre-paid card is bought in a foreign country that supports foreign networks - and that should be almost all countries in Europe. However, a second card excludes inserting a micro-SD card into the only slot that would support this.

Instead of using NFC, the K6000 Plus shares data with compatible devices via HotKnot. Like near-field communication, connecting is only possible in the direct vicinity. The technology is installed under the screen so that, unlike NFC, not the rear sides of both devices have to touch, but their screens.

Finding our position was fast and with an accuracy of up to 3 meters (~9 ft) in the best case outdoors. Localization was also possible indoors depending on the building's composition. Our test in an apartment building presented a result in 11 seconds with an accuracy of 8 meters (26 ft).

The smartphone was mostly on-route on our bike trip where the K6000 Plus had to compete against Garmin's Edge 500 specifically made for cyclists. The measured difference of 140 meters (~153 yd) over almost 12 kilometers (~7.5 mi) was overall correspondingly low. However, sporadic cases recurrently proved that navigating with the smartphone was not as reliable as with the professional device, and this was quite evident in the area of the canal bridge.

Telephony and Call Quality

The K6000 Plus uses standard Android apps for basic functions, such as contacts and phoning. The call quality is good. It is slightly better with the earpiece than via the integrated speaker. However, overall, it is not as clear as with premium smartphones.

Cameras

The front camera with a fix focus and an 80-degree wide angle lens for facilitating groupies has a trendy high resolution of 8 megapixels. The resolutions of selfie cameras in premium smartphones are hardly lower than that of the primary camera. A soft focus is hidden behind an optional beautify mode, and it can already be used in the preview. As the screenshot below illustrates, the exposure correction in conjunction with face recognition functions well, even when light comes from the side. It is possible to select if the photo is to be mirrored in the settings.

The maximum aperture of f/2.0 of the 16-megapixel primary camera is hardly enough to depict poorly lit objects. This can be seen in the 3rd scene of the comparison photos below. Quite decent daylight photos are possible, but they lack sharpness. Details look as if they have been edited with a soft focus. HDR is not present, but a pro mode for correcting brightness, sensitivity and color temperature via the preview is available.

Accessories and Warranty

As well as the smartphone and a 12-volt quick charger (5V/7V/9V/12V / 2A) including the cable, Oukitel adds an adapter for the micro-USB OTG port and a transparent bumper. The mounted screen protector ex-factory can also be left on the handset - and thus, the buyer will not have to spend money on this. Oukitel includes a one-year warranty from the date of purchase. Please see our Guarantees, Return policies and Warranties FAQ for country-specific information.

Input Devices and Handling

Google's GBoard is preloaded, but the KiKa Keyboard was also installed and already enabled. Both share a weakness in the review sample that is due to the touchscreen, or rather its calibration: Both keyboards respond only when the screen is tapped just over the symbols just at the keyboard's lower area, especially in the lower right corner where, for example, the period "." is situated.

A closer look at the KiKa Keyboard is worthwhile: A menu button above the keyboard leads directly to various settings, such as a spellchecker and night mode. It is also possible to choose between standard Emojis and Android Emojis, depending on which set is preferred. Furthermore, it is also used to quickly adjust the keyboard's height to the required visibility of the current app running.

The developers have also come up with some things for quick access to common functions and one-hand use. A few interesting options can be found in the system menu Smart Assistance: Float Gesture enables a menu wheel such as the one we are familiar with from, for example, Samsung, which launches the music or video player or other apps in a window. When a symbol or a letter is assigned to some apps, they can be opened via the corresponding gesture. Unlike some Huawei smartphones that identify these gestures directly on the home screen, a window for gesture detection has to be opened first in Oukitel's device. This delays opening the app.

A float view that is displayed by swiping from the lower right corner is also present. It offers quick access to recently opened apps, volume, brightness, eye filters and other quick settings as well as tools such as a bar code scanner or screen recorder.

As if this is not a decent collection of helpful tools for smartphone use already, Oukitel also uses the installed sensors. For example, calls can be muted by turning the smartphone around or the call can be switched back from the speaker to the earpiece when the smartphone is led to an ear. And users with wet hands wanting to skip a song in the music player can do so by just swiping over the brightness sensor without touching the screen. However, this needs some practice.

Display

Oukitel K6000 Plus – subpixels
Subpixels

Even if the resolution of a 5.5-inch screen cannot be high enough, some simple HD panels are still found in this price range. Thus, Full HD with 1920x1080 pixels and a density of 401 PPI are quite satisfactory. The K6000 Plus has an LTPS screen that supposedly stands out with a high brightness and low power consumption. Neither can be confirmed for Oukitel's smartphone. The undoubtedly good runtime is principally due to a strong battery, and 351.9 cd/m² is a good average at best. With a possible difference of 47 cd/m² between two different sectors, the illumination achieves the not uncommon rate of 87%. These differences are only visible in images with very large single-colored areas.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 2688 Hz ≤ 1 % brightness setting

The display backlight flickers at 2688 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 1 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 2688 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18110 (minimum: 5 - maximum: 3846000) Hz was measured.

The black value of 0.52 cd/m² is acceptable. However, contrasts achieve a ratio of only 710:1 due to the weak brightness. All rivals do a much better job here. The K6000 uses pulse width modification for controlling the brightness at minimum brightness. This is a high-frequency flickering that makes the screen's brightness look weaker. The measured frequency of 2688 hertz is below the determined average rate for this method. Nevertheless, it is still high enough to be perceived as flickering. At most, very sensitive users might find that their eyes fatigue sooner or even get a headache at such a low brightness rate.

The screen's cool color reproduction is noticed in practice. The spectrophotometer in conjunction with the CalMAN software confirms this: A color temperature of 12118 K is measured (6500 K is seen as ideal). Unlike other manufacturers, Oukitel does not offer different color profiles. At least a blue filter that is easy to access in the notification and quick settings is installed for sparing the eyes. Of course, this is not only helpful at night.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
25.6 ms ... rise ↗ and fall ↘ combined↗ 12.8 ms rise
↘ 12.8 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 56 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).

This means that the measured response time is worse than the average of all tested devices (33.9 ms).
Oukitel K6000 Plus - reflections
Reflections

The brightness is just high enough for using the smartphone in the sun. The reflections and weak contrast do not contribute much to legibility. However, should the user want to read a notification, for example, at a concert or in the theater, the screen stays quite bright in minimum settings compared with other smartphones.

The screen's viewing angle stability does not give much cause for complaint. This is particularly evident in the skin tones in the back part of the screenshot that still look natural when looking from the side.

Performance

In the test field, the K6000 is particularly fast primarily in read and write from an external memory card, the Toshiba Exceria Pro M401 reference card in our test. The combination of an MT6750T with 8 Cortex A53 cores (4x 1 gigahertz and 4x 1.5 gigahertz) and four gigabytes of RAM present impressive outcomes in the other benchmarks, as well. It only lagged behind Honor in the standard core and memory benchmarks more than once. However, the 6X's Kirin 655 with 2.1 gigahertz steps out of line a bit in this test field. Despite that, stutters were often noticed in practice, for example when browsing through longer websites in desktop mode. This might be acceptable for the price range, but it can get annoying in everyday use.

Games

In contrast to the ARM Mali-T720 that is found in several of the comparison smartphones, the Mali-T860 in the K6000 Plus supports 1080p (MT6750T: max. 650 MHz). Games such as “Asphalt 8” run smoothly especially since the position sensor does not give any reason for complaint. The K6000 Plus comes with a screen protector that makes clear image areas, such as a bright sky, look a bit grainy. This negative effect disappears when the screen protector is removed. The sensor buttons below the screen, or on the right in landscape mode, can be temporarily disabled when the Float Gesture menu is enabled for preventing unintentional taps that could ruin the game (however, its transparent button always hovers over the image then).

From a speed point of view the seemingly harmless VR game “Pokémon Go” that needs permanent GPS, screen and mobile data connection, is nerve wracking on the K6000 Plus. Just scrolling through the monster list for selecting an arena opponent was sluggish. Following an update in June,  a bug was found that would sometimes introduce an  unsuitable monster to pop up at the beginning of every round and took longer for it to disappear again from Oukitel's phone than on other smartphones in the same group battle and under identical network conditions.

Temperature

Only a slight temperature increase can be determined on Oukitel's K6000 Plus during normal use. Up to 45 °C (~113 °F) were measured during load in the lab - this is high. A minor temperature increase in the left hand's area could be perceived when playing a game in landscape mode. However, the K6000 Plus did not heat up as much as higher performance smartphones in “Pokémon Go”.

Speaker

Oukitel K6000 Plus Pink Noise speaker test
Pink Noise speaker test

The mono speaker reaches a volume of 81 dB(A). Its bass is particularly weak. Frequencies below 315 hertz are almost inaudible. The K6000 is not much better with the trebles than the comparable devices; the audible frequency range of Oukitel's handset is overall narrower. The limited sound range also results in an unfavorable experience that hardly sounds any better than as if the contact were sending music over the airwaves.

Power Consumption

The K6000 Plus already consumes an average of 2.02 watts while idling. Peaks of up to 7.74 watts are even possible during load. This also makes the K6000 Plus look bad even beyond this test field. Positive: Oukitel includes a quick charge power supply for the 6080 milliampere battery. This allows recharging the battery to 100% in less than two hours.

Battery Runtime

6080 milliampere is a dimension that would make some tablet owners get jealous. Such strong batteries usually have too high an impact on the weight of smartphones - as the K6000 Plus proves with 207 grams (~7.3 oz) - and thus, they are rare. The Gretel GT6000 and Blackview's P2 are two of the few. 14 hours and 21 minutes in our Wi-Fi test is a good outcome. However, the P2 easily outruns that. All smartphones in the following runtime comparison have a 5.5-inch FHD screen and, apart from the P2, some have much weaker batteries. The K6000 does not look that good anymore then. Acer's Liquid Z6 is the clear winner here.

Verdict

In review: Oukitel K6000 Plus. Review sample courtesy of Oukitel.

Oukitel's K6000 is an eye-catching smartphone. The aluminum back cover and the matching colors are the primary reasons for this. The buyer should not be deceived by the large battery; the runtime is ultimately important - and it is not much longer than that of comparable smartphones. Furthermore, the large battery is the reason that the K6000 Plus is heavy even for a 5.5-inch handset with over 200 grams (~7 oz). The performance also lags behind the very promising benchmarks in practice.

The K6000 Plus comes with the latest Android 7. The extras that Oukitel adds for fast accessing and easier use make it appealing - the K6000 Plus is suitable for everyday use and it is not only the memory configuration that underlines this. However, it might quickly be cut from the list in view of the increasing demands on image and sound. Although the camera shoots good daylight photos despite a lack of details in sharpness, it is only useful in low light when adding the LED. The sound is even worse: Users who want to listen to music or videos without a headphone should take a look elsewhere.
