Oukitel K4000 Review


oukitel k4000 review

Oukitel have made a name for themselves over the past year making phones with big batteries and long battery life. In this review we take a good look at the Oukitel K4000.

The Oukitel K4000 is Oukitel’s mid range smartphone and boasts a good-sized 4000mAh battery in a phone with just a 5-inch HD display, its not the largest battery phone they offer though! In the Oukitel range there is also the K10000 with 10,000mAh battery, K6000 and a K4000 Pro is due with 4600mAh battery, but for this review we are concentrating on the current K4000. Check out the Oukitel website for more details.

Oukitel K4000 Review – Design

oukitel k4000 review

Open up the box and pick up the Oukitel K4000 and it’s weight and thickness quickly make themselves known. With a screen of just 5-inch the 11mm 208g phone looks portly on first inspection, but once you wrap your hand around it you realise that it’s still easier to handle than a 5.5-inch phone despite its girth.

oukitel k4000 review

Oukitel designed the K4000 to appear bezel-less with the screen off so we have a 5-inch screen plus black borders all around. Its a design that bothers some but not me personally after all a bezel is a bezel regardless of the colour.

Our version of the K4000 is the white model with white face and white removable rear panel. A black version is also available.

Up front the 5-inch HD panel is neatly tucked behind a sheet of glass with a nice 2.5D curve to the edge. 3 non back lit hardware buttons live on the chin and a 5 mega-pixel camera is easily visible at the very top to the left of the proximity sensor.

Like most current mid range phones, the Oukitel K4000 has a metal chassis, and in this case it appears to be a machined steel frame which might explain some of the extra weight.

oukitel k4000 review

The flat sided metal chassis has 45 degree bevel cut at front and rear, and unsurprisingly we find a few features dotted around such as volume and power controls on the right, 3.5mm headphone jack in the top and USB in the base.

There are no SIM trays as the plastic rear panel can be removed to gain access to the dual SIM and micro SD area, plus the user replaceable 4000mAh battery.

oukitel k4000 review

With the curved rear cover in place, shaped with a round contour to fit in your palm, you will find a 13 mega-pixel rear camera, single LED flash, speaker opening and Oukitel logo.

Despite the weight, the phone is actually quiet comfortable in the hand, and overall build quality is respectable, although our sample model does have a rattle coming from somewhere inside.

Oukitel K4000 Review – Hardware

You won’t find any fancy features in the Oukitel K4000, this is a phone designed to have a big battery and offer the longest run time possible. Compared to some phones the lack of dual LED flash, and fingerprint scanner might be a turn off for some users.

oukitel k4000 review

What the K4000 does have is a large 4000mAh battery, and as it only has to pump juice to a 5-inch 1280 x 720 display, 1.0Ghz Octacore chipset and 2GB RAM the cell does a good job of keeping you powered up while on the go. During our time with the phone we managed about 4 hours and 40 minutes of screen on time with LTE and WIFI running.

As the K4000 has a MT6735 chipset the phone runs on FDD-LTE B1/B3 and B7. Other connectivity options include Hotknot, Bluetooth and WIFI.

oukitel k4000 review

The no fuss features of the K4000 continue with the cameras which include a 5 mega-pixel front camera for selfies and a 8 mega-pixel rear camera and single LED flash on the rear.

Oukitel K4000 Review – Performance

In this day and age we are use to phones with at least 3GB RAM and processors running at much more than 1.0Ghz. The K4000 was really designed to be kind to the battery rather than offer out-and-out performance.

Benchmarks are obviously quite low compared to some phones, but in real life the phone works well. Oukitel have done a good job with the Lollipop based rom, and it feels much snappier than the hardware would suggest.

On the original ROM I had issues with the settings menus failing, but an OTA update has solved this.

Oukitel K4000 Review – Camera

Moving on to cameras, the rear camera on the K4000 is actually an 8 mega-pixel sensor which has been interpolated to 13 mega-pixels.

The sensor itself is fine, but I feel the lens on the camera let the performance down. If there are any bright light sources around (such as a bright blue sky) the resulting image is washed out. Keep away from dark and light extremes though and the camera can take some useable photos.

Oukitel K4000 Review – Conclusion

oukitel k4000 review

Checking online for the Oukitel K4000 brings up listings of the phone costing $115, and to be honest I would be happy to spend this much on the phone just for a back up with good battery. If you can live with the weight and lack luster camera, you will be rewarded with pretty good performance and a nice dose of battery life.

Then again, Oukitel will launch the K4000 Pro very soon with a larger 4600mAh battery, fast charging and a promised Android 6.0 Marshmallow update. Perhaps it’s worth waiting for that instead.

    lol , camera get 6 score and ulefone power just 5 with imx214

    • February 3, 2016

      Yea I really dont understand how they grade these scores. Very confusing and unreliable.

    • balcobomber25
      February 3, 2016

      That’s because the sensor is only one small factor. Most sensors are capable of amazing photos, the difference between the good and bad cameras is the optics and optimization.

        wrong score camera, i think real score k4000 = (3)…. 13mpx interpolated cmos, cant win imx214. both default software android. ugly photo review max score 3.

        • balcobomber25
          February 3, 2016

          6/10 is fair, it’s not a great camera but the shots are decent for this phone. You seem to think sensor is the only that matters in a camera, you have little clue what you are talking about. And when we say software for a camera we are not talking about the version of Android. We are talking about optimization.

            default software android camera. not about android version. just low-end camera – just take pictures without available configs

            default software android camera is not about android version. just low-end camera take pictures without available configs. so , homtom ht6, ulefone power, oukitel k4000, k6000, k10000…. low end basic config

              The three phones in that comparison all have superior hardware, not because of the sensors they use because they all use top quality lenses and they optimize the sensor. The Elephone Vowney has an IMX220 it’s pictures look worse than some phones with IMX 258. Sensor means very little.

              Depends on who is reviewing it. Everyone has a different idea of what a 5/10 is for a camera. And some reviewers compare it based on phones of it’s same class, others review it based on overall.

              February 4, 2016

              ex:
              i think you notice that a oukitel k6000 sensor unknown will have the same performance as a premium k6000 oukitel with imx230 using same software but without optimization.

            • xi7
              February 4, 2016

              to be younger and have more feature I believe imx258 performs better than imx220. but soft and device different.

    4hours of screen on time is pretty bad for a device with this specs. I usually get 7-8 hours with the Leagoo Elite with 5.5-inch screen and the same 4000mAh battery.

      I agree. I was expecting the battery life to be much better, and am surprised at the 9/10 rating for battery life.

    SOT of 4:40 with 5-inch 1280 x 720 display, 1.0Ghz Octacore chipset and 4000mah battery seems like it deserves way less than a 9/10

    I’d definitely wait for the “Pro”, but for the price this looks fair enough. And the 4:40 SoT mark is probably achieved under medium to high usage, so no complaints here.

    What’s going on Andi, you don’t seem to even mention this phone, while it’s probably most interesting 5-incher recently??
    You have strage selection critieria, for what’s really most worth attention at the moment – got to admit.
