Lenovo Z6 Pro review

Display

One of the key features of the Lenovo Z6 Pro is the 6.39" Super AMOLED screen with a droplet-shaped notch. It has a very familiar resolution of 2,340 x 1,080 pixels (403ppi) and 19.5:9 aspect ratio.

The screen is HDR10-compliant and fully covers the DCI-P3 color space.

We measured an excellent brightness for an OLED panel of 450 nits - this is at the far-right end of the brightness scrubber. Then we tried the auto brightness mode, but unfortunately, we couldn't squeeze any more nits north of the 450 nits mark.

The minimum brightness we measured was just 2.5 nits.

Lenovo offers two different Color Saturation settings, each one representing a specific color space. The Vibrant one fully covers the DCI-P3 color space and we measured an average deltaE of 3.6. Only in this mode you can choose the color temperature (standard, warm, cool) and the Delta E of 3.7 which we measured was taken at the standard preset. Choosing warm will offer a perfectly accurate presentation with an average deltaE of 1.4.

The Standard Saturation corresponds to sRGB and we recorded an average deltaE of 3.1 for the color accuracy, meaning it's a pretty great one.

Battery life

The Lenovo Z6 Pro is powered by a large 4,000 mAh battery. The phone comes bundled with a 27W Power Delivery charger and it refills 45% of the Z6's depleted cell in half an hour. Oddly, the Lenovo Z6 Pro specs say that the phone only supports 18W (5V/3A) charging so the phone isn't utilizing the full power of the charger.

The phone aced our battery test with excellent screen-on scores, a day of 3G talks, and frugal standby consumption. The great battery performance across our tests returned a final endurance score of 100 hours, an outstanding result!

Our battery tests were automated thanks to SmartViser, using its viSerDevice app. The endurance rating above denotes how long a single battery charge will last you if you use the Lenovo Z6 Pro for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern so that our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritty. You can check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.

Speaker

The Lenovo Z6 Pro features a single bottom-firing loudspeaker. It is quite loud though as it managed to score an Excellent mark in our loudness test.

Oddly, when playing music from YouTube or Play Music through the speaker, the loudness isn't as impressive. But on a positive note, the output is very balanced and rich in both high and low notes.

Audio quality

The Lenovo Z6 Pro has an issue with its software that prevented it from showing its full skill set in our audio test. You only get different settings for its system-wide equalizer but no option to fully switch it off, which means that getting accurate output just isn’t possible. We chose the setting with the sanest frequency response, but even so, it was way outside the limits of what we’d consider accurate representation.

We're not saying that many people can tell the difference, but some will. Anyway, it's strange to see that behavior since pretty much every other smartphone these days can output a flat frequency response line.

Frequency response aside, the clarity of the output is actually very decent with all the other scores being excellent both with an active external amplifier and with headphones. Our standard 32-ohm headphones even caused much less damage than usual to the stereo separation.

Then we have to look at loudness, which is below average in both parts of the test. While the equalizer issue might get fixed with a firmware update we are less certain anything can be done about the relatively low volume. It will probably affect users with larger high-impedance headphones.
