Lenovo Vibe K5 review: Base line

5-inch display with 720p resolution - can't complain

The Vibe K5 relies on a 5-inch 720p IPS display. The resolution is one of the few downgrades, compared to the Plus. Or rather the Vibe K5, being the base model, gets the base resolution. At 294ppi, pixel density is still good enough, even if we have to add "considering the price" once again.

No surprises when we put it under the microscope - the Vibe K5's panel has a standard RGB layout with an equal number of subpixels for each primary color.

The Vibe K5's display is capable of more than 400nits of brightness in its default mode, which isn't spectacular - more like average. Its black levels aren't too good either, and that somewhat ruins contrast.

Color reproduction is reasonably accurate in default mode, with an average DeltaE of 6.1. You can adjust the colors in settings and achieve an average DeltaE of 3, but at the expense of maximum brightness, which drops by about 100nits.

In the sunlight legibility test the Vibe K5 posted virtually the same score as the Plus. The dispay being one of the few parts not shared between the two, we thought this might be an area where they performed differently. Well, they didn't and the Vibe K5 scored a good figure for an LCD - not iPhone-6s-good, but better than the HTC 10, for example.

Connectivity

The Vibe K5 is a dual-SIM smartphone and it takes microSIMs in both slots. Both are 2G-capable, but only one gets the 3G/4G treatment. LTE is Cat. 4 for theoretical transfer speeds of 150Mbps down and 50Mbps up. It has a dedicated microSD slot - so no dilemmas between extra storage and a second SIM.

You get single-band 2.4GHz Wi-Fi b/g/n (no ac) with hotspot support, GPS with A-GPS, Bluetooth v4.1, and an FM radio receiver. There's no NFC or an infrared port, though.

The microUSB 2.0 port is USB OTG enabled, and you also get a standard 3.5mm headphone jack.

Lenovo Vibe K5 battery life

The Lenovo Vibe K5 packs a 2,750mAh battery - the same as the K5 Plus. A different (supposedly more frugal) chipset and display resolution sound like the right way improve battery performance but this isn't the case.

The Vibe K5 posted largely the same numbers as the K5 Plus, and while that is more of a testament to the Plus for squeezing the same endurance with higher-grade hardware, this plain K5 is by no means inadequately powered.

Close to 9 hours on the web over Wi-Fi, and 8 hours of video playback are average numbers, and actually pretty good for the battery capacity. The 3G talk time isn't great, at 13 hours, and that's where the K5 Plus lasts a little longer.
