Lenovo K6 Power Smartphone Review

Lenovo K6 Power Review

The Lenovo K6 Power is a compact 5-inch display Android smartphone from Lenovo. Even with this small size and miniature design the K6 houses a massive 4000mAh battery. Hence getting the moniker of Power in the Lenovo K-series smartphones. 

The metallic body finish, impressive specs, gripping software experience and with an enduring battery life, the K6 Power offers an economical phone which doesn’t make a hefty dent on your wallet.

Lenovo has come a long way in targeting budget markets with its full specs low budget smartphones. Lenovo has been perhaps eyeing Xiaomi’s smartphones and for that K6 Power shares many resemblances with the Redmi 3S. But the question is can Lenovo hold its ground in competition with the Xiaomi or in that case many other market contenders? We’ll shortly find out.

Design and Display

The Bar design of the phone has rather a premium texture with the metallic back and has a relatively good frame. The compact 5-inch design makes it pretty handy and slippery as well.

Lenovo arguably has taken some inspiration from the Xiaomi phone designs, and appear amusingly similar apart from slight differences in look and feel.

The phone is well built, the softly curved sides make it pretty comfy to use while the metallic case has the capacity to survive the occasional tumble. The front features capacitive navigation buttons, 5-inch 1080p display, and the front camera.

On the right side of the phone are power and volume buttons, and on the left side is the Nano SIM slots. One peculiar design feature of the K6 Power is the position of Micro-USB charging port which is located at the top of the phone right next to the audio 3.5mm jack. The navigation buttons are not backlit which makes things a little difficult while using, though the power and volume buttons are pretty handy and decent.  

On the back, the accentuated chrome linings around the camera lens, fingerprint sensor, and the grey antenna lines, that separates the color scheme make the phone look splendid. While the back also hosts Dolby Atmos stereo speakers on a rather not very ideal position. But I guarantee once you hear them you won’t even utter a word of complaint about their position, they are just amazing for a budget phone.

The design of the K6 Power is pretty similar to the recent budget phones in the market, like Redmi 3S Prime. With a weight of 145g and 9.3mm thickness, the K6 Power is perhaps not a very stylish phone available in the market. And the bulkiness of the phone is credited to the massive 4,000mAh Li-Po battery, which also is the most compelling hallmark of the phone.

The K6 Power has a maximum brightness of 450 nits, which is pretty good for sunny environments. Though the ambient light sensor is not up to the mark and lags to adapt to the changes in light conditions. 

The display of the phone is 5-inch full HD IPS LCD and has extraordinary viewing angles, with saturated colors and a pixel density of 441ppi, all these combine to make the multimedia experience an enchantment. The phone has a brightness protection mode which is basically a night mode. The normal mode balances the color scheme and color temperature bringing it to more realistic colors.


The 13 megapixel’s camera with a single LED flash has phase detection autofocus. Powered by Sony’s IMZ258 sensor, can record 1080p  video at 30fps. Has an 8MP forward-facing wide-angle camera.

The images captured with the camera are noiseless due to the noise reduction algorithms used by Lenovo. The captures are detailed and color contrast looks natural with the right amount of light. It offers panorama mode, slow-motion video and also a night mode to filter the low light conditions. Though, in low light conditions, the images lack sharpness.

The K6 Power comes with Android 6.0.1 Marshmallow. The phone has received updates to Android 7.0 Nougat, bringing in updated features. The Vibe UI with a custom app drawer has Lollipop flair with horizontal scrolling, has a search bar for apps at the top. While Vibe UI is a custom UI by Lenovo, it has not cluttered too much and leaves room for the stock Android features to peek out.

Lenovo has made ample changes in the interface, adding the double tap wake-up gesture, to take an image with the volume button, press the power button twice will launch the camera. It also provides an app locker called Secure Zone that lock apps with password or fingerprint. The dual app attribute permits you to simultaneously run two instances of an app i.e. two WhatsApp accounts run on the same device. Vibe UI is much elegant and cleaner than most ROMs provided by other Chinese vendors.

Even though the smartphone is running on ageing android nougat. Custom rom developers have extended the support for the device to lenovo k6 power. you can install the custom rom on your device with this following guide.

Powered by Snapdragon 430 system-on-chip, the K6 Power has four 1.4GHz Cortex-A53 cores, with the Adreno 505 GPU. The phone offers 2GB and 3GB of RAM variations, 16GB/32GB of storage capacity, and a microSD card slot that supports up to 256GB, also the phone has dual hybrid Nano-SIM connectivity. A hybrid slot has the capacity to support either a SIM card or a microSD card besides the primary SIM card. The K6 also supports all the 4G bands available in India with VoLTE, and Bluetooth 4.2.

The phone’s hardware performs satisfactorily through everyday tasks and doesn’t lag or slowdown during normal browsing, messaging, multimedia, or in any day-to-day tasks. The K6 serves all the features of a compact smartphone with an amazing multimedia powerhouse.  

Budget phones have come a long way and the likes i.e. K6 Power, Redmi 3S, are now impeccably sensible for everyday usage. With that said the K6 Power does have some deficiencies as well, especially when playing high-resolution games. Visually intensive operations are not perfectly handled by the low power Snapdragon 430. If you are a hardcore gaming fan, then you’ll probably look for higher power processors like Redmi Note 3 powered by Snapdragon 650.

As mentioned earlier the stereo speakers are wonderful. The Dolby Atmos speakers serve quality sound with detail even at high volumes. You can twist the Dolby settings as well to customize the sound to your needs. The fingerprint sensor on the rear of the phone is precise and fast in authentication. Overall the size and design complement the hardware to a certain extent and you’ll feel at home while using.

Running on Snapdragon 430 chip the Lenovo K6 works rather satisfactorily. Opening and closing of the apps are practically swift for an economical smartphone. Though the custom scrolling by Lenovo a glitch you’ll feel pretty soon.

On the GeekBench 4 tests, the K6 performed lower than its market contenders like Xiaomi Redmi 3s Prime. The Snapdragon 430’s low power also affects the phone’s capability to play higher resolution games and videos, as the K6 can only manage to play up to 720p display at a reasonable frame rate. 

The stereo speakers are the golden spots of the device as they sound quite good compared to other expensive devices. The Dolby Atmos speakers convey amazing clarity, and projects the sound in three dimensions meaning you as a gamer get an astounding sound experience. 

Battery life

The most plausible feature of the Lenovo K6 Power is the massive 4,000mAh battery it houses. Lenovo assures two days of battery life and the claim lays pretty possibly. From a full charge, you’ll most often than not get two day’s usage, otherwise, easily serving a full day intensive use. The insane battery life is also served by the frugal processor of K6.

The phone has an Ultimate Power Saver mode which restricts the phone to serve functions of calling and messaging, disabling all the other smartphone features. It also has a battery saver mode that is activated automatically when the charge hits the 15 percent threshold.

The K6, however, lacks the fast charging support, which can get pretty annoying with the huge battery it holds. It takes around two and a half hours to completely charge the device, and the charging slot is at a peculiar position on the device. The good side though, it can be used as an external battery pack to charge other devices. All in all, you won’t feel any glitches on the battery running dry, even if you consume loads of multimedia round the day.
