K6000 Pro - Review

Introduction

Following their previous battery-phone flow, OUKITEL decided to upgrade their well-made K6000 with major differences. The OUKITEL K6000 is entirely based on its previous model, but with an upgraded CPU, increased RAM/ROM, a better screen and some other minor differences. Somehow they have removed the Notification LED, but they have added an useful Fingerprint Sensor. They probably had to remove something in order to keep its price low.

This is the OUKITEL K6000 Pro

Hardware

This device is powered by a Mediatek MT6753 SOC clocked at 1.3GHz, with a plenty amount of RAM (3GB) and ROM (32GB). It shares the same Rear Camera sensor used by the Huawei P8 Lite (13MP OmniVision OV13850), not bad at all, while the Front Camera sensor is an excellent 5MP OmniVision OV5670. Another interesting hardware component on this device is the Screen, it is made by AUO and provides an excellent viewing experience, with superb brightness and color reproduction. Follow my next paragraphs to know more.

Unboxing

Packaging comes with many accessories: 1x TPU Cover (transparent), 1x Screen Protector (Plastic-made), 1x SIM/MicroSD tray Eject Tool, 1x Micro-USB Cable, 1x OTG Cable, 1x 5V/7V/9V USB Quick Charger, 1x Manual and the Smartphone (of course). No Headset included.

Just like the K6000, also the K6000 Pro has a Metal Chassis, with a Metal Back Cover. The device feels absolutely solid, it doesn’t feel too heavy too even if there is a 6000mAh battery inside. All is supported by a nice design.

It is just 15.5x7.8x1.04cm, not so slim, but don’t forget that there is a 6000mAh battery inside, and it weights 214g, not so much.

On the front side there is the 2.5D Curved Display, that makes the usage of the device much more ergonomic. The Glass is enclosed in a Plastic Frame, which increases the device’s toughness, while the upper front side of the device features a Front-Facing Camera, an Earpiece, and the Sensors hole that includes Light, Proximity and Gesture Sensors. Unfortunately No Notification LED is here.

On the lower front side of the device there are the Soft-Keys Navigation Buttons (not retro-illuminated).

On the back side there is metal back cover, but on the upper and lower sides of the back cover there are two plastic covers, probably used for the antenna stuff.

The upper rear side of the device features a slightly protunding Camera supported by a Dual-Flash (Single Tone) configuration, and the small rounded Fingerprint Scanner.

The lower rear side of the device features the Brand Logo and the Speaker hole.

Unlike some other Chinese Smartphones, the SIM Card/Micro-SD tray has been well designed to allow the usage of a Micro-SIM and a Micro-SD without having to replace your SIM with a Nano variant. So you can use a Micro-SIM and a Micro-SD in the same time.

Device

Screen

OUKITEL, even if they do not declare it, choose an high-quality IPS screen on this device, made by AUO. Probably one of the best screens I have ever tried, with a nice balance between brightness and image quality.

Brightness is great, without no issues at all under direct sunlight. The Light Sensor works great too, and supports smooth light changes making auto-brightness much better.

About Viewing Angles, the screen doesn’t suffer any kind of issue, it behaves perfect in every single condition.

Camera

Even if the Rear Camera has some of the best technical specs available as regards mid-high end sensors, the camera software hasn’t been optimized at all. Even if you play with the settings, you won’t be able to take photos with no noise or with just low noise, you’ll always take extremely noisy photos that doesn’t look pretty well. OUKITEL, please work on it because this Camera Sensor can work much better.

As you can see, HDR makes photos brighter just like it should.

Flashlight is extremely powerful, unfortunately it isn’t dual-tone, but it helps a lot in almost every condition.

As regards Video Recording, there are no major issues. 1080p videos (Video Quality – Fine) are recorded with a decent level of details, just remember that there is no OIS so you can’t expect stable videos.

Front Camera is good, probably better than rear camera as regards noise level.

Audio

Speaker isn’t loud, a bit poor as regards its power, it lacks low-frequencies but there are no issues with Sound Clarity. You can’t expect more for this price.

Unfortunately, it is positioned on the back, and, as I have already said for many other devices, if you place the device on a table you could experience volume issues, but this doesn’t mean that it is a bad thing. As always, what matters here is the quality.

Nothing negative to say about the in-call/telephony quality.

Telephony, Mobile Network & WiFi

Thanks to the 4G Band 20 support (some other Chinese Smartphones don’t have it), I’m almost always and everywhere connected to the 4G Network of my Mobile Network Provider (TIM Italy).

Also 3G Signal Reception is accurate, actually I never managed to get connected to the 2G Network of my Mobile Operator because there was always some 3G Signal available.

4G Network Speed is decent, it highly depends on your Mobile Operator and mine isn’t pretty good. While 3G Network Speed, is just fine.

This is a Speed Test taken using my poor 4G internet connection, unfortunately I won’t be able to show a better one. (poor mobile network operator)

There is no WiFi 5GHz support here, but WiFi 2.4GHz speed isn’t extremely low, I managed to get connected to my network connection at 65mbps, and Speed Tests reach more or less 40mbps.

Battery Life

I have measured the real battery capacity using my USB Tester, and as you can see it is almost correct. (declared 6000mAh, real almost 5850mAh)

I’m able to reach more than 10 hours of screen-on time with everything on (Sync, Location, 4G, WiFi…), and this GeekBench Battery Benchmark made without 4G on (only WiFi), confirms it.

If you are worried about charging times, you don’t have to. OUKITEL provides a Quick Charger (with MTK Pump Express Plus tech.), similar to Qualcomm’s Quick Charge tech., that allows you to charge the device completely in more or less 2 hours.

Software

OUKITEL choose to use an almost completely clean Android 6.0 release and it works much better than many other devices I have tried. It offers the same Nexus experience, just with some add-ons that you can choose to enable or not.

Just like other last-gen Mediatek Devices, there are some typical features such as Gestures, Scheduled Power On/Off, etc…

The UI is extremely responsive and smooth, with no lags at all (except the screen rotation animation). I didn’t managed to find any software issue, so...well done OUKITEL!

As regards the Fingerprint Scanner management, it can be configured via the Settings apps and it can be configured easily, unlike other Android 5.1 devices. Also, it gets unlocked pretty fast without major accuracy issues (it isn’t perfect, but pretty good).

Benchmarks

I have used 3DMark, Antutu Benchmark, Epic Citadel, GeekBench 3, GFXBench, AndroBench, PCMark (Work & Storage) and Vellamo (Browser & CPU Tests) to stress the device to the limit. I won’t test Games or Video Playback because there are already some related tests included in these Benchmark suites.

3DMark – GPU Performance isn’t extremely good, OpenGL 3.1 & 3.0 tests require lots of power, and this is where almost every mid-range GPU falls. OpenGL 2.0 tests are pretty good though.

Other 3DMark tests can be found on my Imgur album linked at the bottom of the thread.

AndroBench – eMMC Performance seems to be decent, especially as regards Reading Speed. Writing Speed isn’t as good as other devices though, but still good.

Antutu Benchmark – I won’t say a lot about this benchmarks, this isn’t as reliable as others. I’m providing this just for benchmarks lovers.

Epic Citadel – As you can see, 3D performance isn’t so high, but still enough for almost all games.

GeekBench – CPU Performance is nearly as good as other CPUs with the same configuration (8x Cortex-A53), enough to handle almost every type of activity. It could have been better though.

GFXBench– GFXBench score is low, but you can’t expect something better with this CPU.

PCMark – As you can see, only Writing score is a bit low. Pretty good.

Work

Storage

Vellamo

Browser score is probably lower than expected.

The same for the CPU score. Multicore score is nice though.

Performance could have been better, but i’ll wait next OTA Updates to express a final opinion about it.

Conclusions

Even if there are some issues with the Camera Software, everything else is almost perfect, so I can clearly say that if you need a device that features an huge battery and has high-quality components inside, then this is probably the best choice.

Just because I know that this device could work even better, please stay tuned to this thread so that if I manage to find any improvement with the next OTA updates, I will specify them and update the review.
