Oukitel K6000 Plus review

The Oukitel K6000 Plus is the latest in the K6000 lineup and improves upon the K6000 Pro by including the newer, faster MT6750T SoC, 4GB RAM and 64GB storage.

Oukitel has also moved the fingerprint sensor to the front on the Plus. It’s about $30 more in comparison to the Pro; for the extra juice and storage it’s worth it.

I reached out to Oukitel and within six hours had a reply as to which of my requests could be added.

Oukitel K6000 Plus review display

The LCD protection is 2.5D Arc Dragontrail hardened glass. In the box are two screen guards, one already applied to the display and an extra.

Once you go glass, you never go back and we went ahead and ordered an inexpensive glass screen protector off of eBay. It’s much nicer to look at, smooths the display out a notch and stays generally scratch free compared to plastic guards.

The display on the K6000 Plus leans moderately towards a cold white balance. I normally prefer white balance leaning towards a warmer/bookish and there are several ways to achieve this if the coldish balance isn’t for you:

  • by tapping the Eye Icon in quick settings to instantly add a bit of warmth
  • in Settings >> Display >> MiraVision >> Color Temperature
  • or, Settings >> Display >> MiraVision >> Bluelight Defender

All three of these methods can be used to get a white balance that’s most appealing to your eyes.

The display looks very good:

  • only minor IPS glow
  • excellent color and contrast retention from extreme angles
  • no evidence of LED light placement
  • text is smooth and looks good.
  • color has good pop without going overboard.

Maximum brightness is a solid 330lux. Minimum brightness is a fairly nighttime friendly 13lux, and if you switch over to auto-brightness the display can dim to an excellent 1lux.

Oukitel K6000 Plus review OS

The Oukitel K6000 OS was missing a few features I appreciate. I reached out to Oukitel and within six hours had a reply as to which of my requests could be added. I am truly impressed by the Oukitel team.

Yes, we are a review blog, so it makes sense they’d want to be responsive, but it’s important to note that not all brands respond as Oukitel did when we make ROM requests and suggestions.

My favorite thing about Android 7 is integrated multi window mode. This allows you to have two apps on the display at once. Typically I use this function for watching a movie while surfing, chatting, or Facebooking.

Another excellent move by Oukitel is having an appropriate DPI. Some manufacturers have a tendency to oversize things, and even when setting text too small you can’t fit a lot more on the display than if you were using a 5.0″ phone. With the Oukitel K6000 Plus they make great use of the screen real estate.

OS quick notes
  • Android 7.0 Nougat.
  • Slow scrolling is smooth with no jitters.
  • Fast scrolling is quick and with appropriate friction / inertia.
  • Oukitel K6000 Plus ROM OTA downloads and updates without issue.
  • Google Play downloading and installing apps without issue.
  • System transitions and animations are smooth.
  • Switching between apps in memory is very quick.
  • Apps remain in memory right where you left them, even many hours later.

Overall, the MT6750T Oukitel K6000 Plus ROM is very responsive and without issue.

Though Snapdragon 625 handily beats MT6750T in benchmarks, when comparing responsiveness to the Redmi 4 Pro with Snap 625, in terms of real world general use the MT6750T in K6000 Plus generally performs just as well, and in some cases even better; this is especially true when switching between apps where there is a slight pause with Redmi 4 Pro before the app is ready to go, and with the K6000 Plus the app in memory comes instantly up and ready. This is possibly an MIUI thing, but whatever the case I’m impressed with the Oukitel K6000 Plus user experience.

Oukitel K6000 Plus fingerprint sensor

On the K6000 Plus Oukitel has moved the fingerprint sensor to the front of the phone. It’s an excellent implementation, with scanning in bringing you directly to where you last left the phone.

From the time you put your finger on the sensor to the time you’re into the phone is <1s. Your finger can be placed at any angle to scan in.

Oukitel K6000 Plus review battery charging

Curious to see how the K6000 Plus performed with a standard 5V 2A charger we found it charged fully in about four hours. Stepping it up to the included PumpExpress charger the 6000mAh Oukitel K6000 Plus charged fully in two hours.

The beauty of this super fast charging is that over lunch or a quick coffee break you can put enough juice into the K6000 Plus to last you several hours of onscreen use.

This is applicable in real world situations and actually came in handy for me the day I wrote this review; seeing the battery at 20% and knowing I had a several hour bus trip ahead of me I put the phone on the Oukitel supplied charger. After about 30 minutes I came back to the K6000 Plus at 53% and from this 30% of charging I got over 3 hours of screen on time.

Oukitel K6000 Plus review battery life testing SOT (screen on time)

One of the draws of the K6000 Plus is its huge 6000mAh battery. We tested the battery with our charging meter and found out the 6000mAh claim to be true.

Running the K6000 Plus battery down in our WiFi 140lux YouTube 720P test the battery lasted 12h 30m , which is a good result and means most users will get 6-10 hours of real world screen on use. NOTE: The screenshot shows 11:54. This test was done from 4.2V down. The battery when fully saturated charges to a solid 4.35V. We ran the video from 4.35V down to 4.2 and this gave us approximately an additional 30m, hence the score of 12h 30m.

Another test of actual use turned out some fantastic results, with the K6000 Plus lasting nearly 5 days and achieving 7h 44m screenon time. Use during this period was WiFi, lowish brightness, Facebook, browsing, chatting, flipping around the phone, and watching videos.

Oukitel K6000 Plus review camera

The Oukitel K6000 Plus camera is OmniVision OV16880. The OV16880 is a true optical 16MP sensor and uses OmniVision’s PureCell-S technology.

I found the images from the K6000 Plus to be good. Some may find the color in bright daylight shots to be a bit oversaturated (see the flower shot), but this can easily be adjusted.

Sharpness is good across the frame. The camera focuses quickly and accurately.

These shots are easily good enough for social sharing, and with a couple of edits in SnapSeed or similar app can be looking great.

All images in the gallery below are unedited, straight from the camera and non-HDR.

I’ve also taken a few non-flash indoor shots taken under dimmish/typical house lighting and they came out more than fine. They can be seen at the end of the album. If you would like to see the photos from the album at a bigger size and compare them to other phones, check out our Flickr albums (opens in new tab).

Oukitel K6000 Plus frequency support

North Americans will want to avoid the Oukitel K6000 Plus, but for Asia, UK and Euro the Oukitel K6000 Plus is a great choice frequency wise. It also has 800 band LTE which is important in some areas of UK/Euro.

Oukitel K6000 Plus build and style

Due to the 6000mAh battery this isn’t what you would call a thin-and-light phone, but this isn’t necessarily a negative. It feels solid in the hand and the front looks awesome with the 2.5D Arc full black display. The sides are CNC machined metal. Build quality of the Oukitel K6000 Plus is great.

Oukitel K6000 Plus review conclusion

I find the lack of a compass a bit strange and I’m not sure what Oukitel was thinking here, but in terms of practical use, not having a compass should not affect most users.

The K6000 Plus is very well built, comes with Android Nougat, has a huge 4GB RAM and 64GB storage, a very good looking display, excellent WiFi and GPS, and great battery life.

This is the first Oukitel we’ve reviewed and I’m very impressed. Build quality is excellent, and we could find no hardware issues with the phone. This is a phone I’d have no problem using as my main mobile.
