Call Quality

We had no issues with call quality on the K6 or K6 Note. We heard our callers sufficiently loud and clearly via the earpiece, and on the other end of the line our voice was also heard clearly. Also, we love the good travel, feel and convenient positioning of the volume rocker, which makes it easy to adjust volume levels while on a call.

Battery life

A battery champ.

It’s almost become the rule these days: affordable phones get impressive battery life figures. The Lenovo K6 and K6 Note are no exceptions, and this is their second big advantage.

The K6 features a 3,000 mAh battery, while the K6 Note touts a 4,000 mAh battery cell. Combined with their frugal Snapdragon 430 system chips and some careful optimization on Lenovo’s part, this allows an average of two days of battery life. In fact, while using the K6 I was getting three days with my more moderate usage, which is definitely an impressive achievement.

The K6 and K6 Note broke the 10-hour mark on our custom battery test, scoring around 10 hours and 40 minutes, while popular phones like the Galaxy S7, Google Pixel and iPhone 7 averaged around 7 hours on the same test, set at the same brightness level.

Battery life (hours) Higher is better
Lenovo K6 10h 40 min (Excellent)
Lenovo K6 Note 10h 47 min (Excellent)
Samsung Galaxy A5 (2017) 11h 9 min (Excellent)
Motorola Moto M 7h 8 min (Average)


So there you have it, the full picture of the new Lenovo K6 and K6 Note: affordable phones with great battery life, a fast fingerprint scanner and impressively loud dual speakers that do well in daily tasks. What they are not is pretty or well designed, and what they are most certainly NOT is good camera replacements.

It would have been easy to write these two off right away, but let’s first look at their prices. Lenovo has set the following prices for these two phones: the K6 is sold for somewhere between €150 to €200, depending on the market, while the K6 Note prices vary between €190 and €220.

Does that justify all the big compromises that you have to make with these two? Let us give you all the options: for the same price you can get the very good Moto G4, which lacks a fingerprint scanner, but has a cleaner, more refined interface and a much better camera, while for €40 more you can get the Moto G4 Plus that has a fingerprint scanner and is a further jump in terms of quality. At the same cost, you can also get the better designed and better performing Huawei P9 Lite.


  • Impressive battery life (2 to 3 days on average)
  • Loud dual speakers
  • Fast and accurate fingerprint scanner
  • Affordable price
  • Decent performance


  • Terrible camera quality (for both photos and videos)
  • Outdated software version (6.0 Marshmallow), no clear path for updates
  • Clunky Lenovo user interface
  • Gruff design, slightly chubby body
