Lenovo ThinkBook 14s Yoga Gen 3 review – this is one fantastic little business convertible

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.

Average P-core frequency; Average E-core frequency; CPU temp.; Package Power

Okay, you shouldn’t read too much into this particular test in the case of the ThinkBook 14s Yoga Gen 3. Its frequencies showed a very weird behavior when we started the most CPU-intensive load on Prime95. Apparently, the software didn’t really want to push the system to the max, as the power draw was too low. On the other hand, the device performs really well in synthetic benchmarks and in real life.

Comfort during full load

And because of the low response from the CPU, the fan barely spins, and there is very little heat felt on the keyboard.

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. This device’s 60Wh battery pack lasts for 11 hours and 54 minutes of Web browsing, or 9 hours and 49 minutes of video playback.

Video playback

Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
