Lenovo ThinkBook 16 Gen 6 (Intel) review – Great for Work, Easy on the Ears
Temperatures and comfort, Battery Life
Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

The Core i5-1335U here can maintain decently high clocks in short loads. However, in medium and long max stress, the P-core frequency is sub-1.0GHz.
Comfort during full load
The low P-core clock has its good side – the fan is near-silent even when the CPU is loaded at 100%. In this case, the keyboard feels a bit warm in the center but nothing serious. The three performance presets can be found in the Lenovo Vantage app. If you enable the auto-transition to the “Extreme Performance” mode, the machine can dynamically switch between the mentioned preset and the “Intelligent Cooling” mode, depending on the load.
Battery
Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. The 45Wh battery lasts for around 10 hours of Web browsing or 8 hours of video playback. To achieve that, you have to apply the “Balanced” preset in the Windows “Power & Battery” menu and select the “Intelligent Cooling” mode in the Lenovo Vantage app.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better

ThinkBook 16 G6 ABP (21KK) Battery uses the highest quality graded and sorted ‘A’ Grade cells.
do suggest between E series and thinkBook 16
We currently have a review of the ThinkPad E16, so read both and try to see what’s more important for you. From our experience, ThinkPads and ThinkBooks are very similar, they just have different designs.
We have about 20 ThinkBooks at work and i am not happy with their robustness compared to Thinkpad L series we have. Electronics are ok, not that many more failures than L Thinkpads. Can’t speak for E series because we don’t have any.
What about configuration with core i7 13700H processor and 71 W battery, will it still last around 10 hours of Web browsing on a single charge or it is only true for configuration with Intel u-series processors and 45/71 W battery?
ja
Absolute non-sense battery review. I own thinkbook 16 with Intel u7 and it barely lasts 4 hours of internet browsing and all battery saving options are enabled. 7 hours is unachievable. This test is clearly faulty
trash, loud fans, gets hot easily
loud fans with having on old app that should be no effort for it !
bad quality!
